MRCOOL DIY Mini Split, Seriously, I Think...

Pretty sure I am about to pull the trigger on an 18K version of the MRCOOL DIY mini split. I am put off a little by the lack of reviews, and the thing seems too good to be true, but... There aren't any negative reviews, either the things work great and almost no one bothers to post a positive review, or they have only ever sold about 5 of them. And if 2 of those 5 were bad, we all know there would be negative reviews all over the internet.

I have to do something, I had the garage insulated when it was built, and we are reaching the season where it is going to get hot in there and stay hot, plus as I was warned, the humidity is obviously high inside. We have seen upper 80's to low 90's so far, and I am sure I will not be using the space much without A/C.

I have a couple of quotes, one for a Trane (actually a rebadged Gree) and one for Daiken, each around 4 grand before we start talking about rebates and incentives and all. I think they got the Trane down to $3,600 and 0% financing for 36 months or such. I'm all about supporting good local companies, and yes, the expertise and warranty on the work is worth something to me, but I can't see over 4K for a unit I can buy on the internet for $1,200 with a different sticker. I was all but told that they essentially charge the same prices for mini splits as traditional split systems. I guess duct work and wiring separate thermostats is free. I have already spent way over what I intended on this garage, I don't see another 3 to 4 grand, even if it is financed at 0%.

So... For $1,200 I can have a pre-charged unit with a nifty pre-charged line set deal delivered to my door. If it lasts 3 or 4 years I think I still get my investment out of it. It is supposed to have a 5 year warranty on everything, 7 on compressor. Of course if it needs a compressor in 5 years, it's probably time to replace the whole thing.

I have thought about window units, but a window unit with heat and cool in the same BTU is $600 or so, and the mini split should be more efficient to operate. Plus I am not supposed to have a window unit in the neighborhood, and I don't really want to give up the window. I would likely still need a dehumidifier also.

Thoughts ? Encouragement ? Talk me down ?

If I go forward, I promise it will be posted and reviewed here for everyone to see.

Thanks for reading the rambling,

A friend of mine is approaching retirement. He has just a few years left and he is already making plans. One of these plans of his was to purchase a small cottage in the Ozarks. For those of you who aren’t from Kansas City, the Ozarks are a few hours south of here and are very similar to Appalachia. There are lots of forests, rivers, and hunting to be had. The place he purchased came with over thirty acres to play around with. The home though was rather small at only around twelve-hundred square feet. The home was also very old and did not have a central air conditioning system. There was an old window unit in the living room that did a mediocre job of cooling the home but it didn’t help for the winter months, it didn’t reach the bedrooms, and it needed to be replaced anyways.

He brought this up a few weeks ago when we were having a few and I told him to look into getting a ductless system. You see a ductless system can give you significantly more power then a standard window or mobile air conditioner. Along with the additional power it is much less of an eye sore. I didn’t see the old window unit that he had at his home but I can only imagine what it looked like. You’ve all seen them. Those old rusted looking units that look like they could fall at any moment. A ductless system mounts to your interior wall and to the outside of your home. You don’t lose a window. You don’t have to cut a huge hole in your wall to fit the wall unit. All you need is a three to four inch hole to fit the refrigerant lines through and you are good to go!

Personally, I am a big fan of ductless systems. Obviously, I am going to go with a central unit first if it’s possible, but if it’s not then I am going for the ductless. Yes they are more expensive but you are getting a better product too. In this article we are going to take an in-depth look at one of these ductless systems, MRCool Do-It-Yourself Smart Air Conditioner and Heater.

Please note that this will be a comprehensive review. I will try and cover everything including sizing requirements, installation, product features, the pros, and the cons. You can expect a lot of reading on your part but at the end you will definitely know what you are getting into and if this is the right product for you and your family.

Ok folks so before we get into the features and the pros/cons of these air conditioners from MRCOOL I want to cover a few topics: Sizing and Installation. These sections are key for when you are shopping for a ductless system. The sizing allows you to accurately predict exactly what size air conditioner that you need and the install section will give you an idea of what to expect when the air conditioner arrives at your home.


Before you buy we need to understand how sizing in air conditioning system works. It is not as simple as just picking the biggest and baddest model on the market. If you purchase a unit that is rated to cool one-thousand square feet and you put it in your one-hundred and fifty square feet office your air conditioner is going to have difficulty extracting the humidity from the air as well as evenly distributing the cooler air. The end result will be hot and cool spots throughout the room. That isn’t even mentioning the increased monthly cost to run a much larger machine then you needed in the first place. This will leave you feeling frustrated due to the hot and cool spots as well as paying more money per month then you should be.

Now, if we do the inverse of this scenario and buy a smaller air conditioner for a much larger area your unit will be running constantly all day and night just trying to keep up by cooling the larger square footage. This will result in the room not being as cold as it should be as well as significantly increasing the energy bills for running your AC non-stop. Remember folks, air conditioners are supposed to hit a desired temperature, turn off, and then turn back on when the temperature begins to rise. If they are running constantly that means higher bills as well as quicker parts failure on the unit.

To understand air conditioner sizing you need to understand British Thermal Units, or BTUs. If you have already been looking online or in stores you have probably noticed that window air conditioners always have a BTU number in their description. BTUs are the traditional measurement unit of heat.  In the air conditioning world BTUs are a measurement of the cooling capacity of your window air conditioner. The bigger the number of BTUs the more powerful and the higher cooling capacity of your A/C unit.  As a standard measurement an air conditioner needs around thirty BTUs for each square foot of living space that you wish to cool. Using that standard measurement let’s do some match based off of the 24,000 BTU rating example we pulled from earlier.

24,000 / 30 = 800 square feet

To ensure that you are buying the right sized air conditioner for your room it is best to measure it. To get the square footage of your room measure the width and depth of your room and then multiply the numbers together to get your square footage. As an example if you have a ten foot by eleven foot room you have one-hundred and ten square foot.

There are also other considerations when looking at your room. Yes, the size of the room definitely matters but these other scenarios could have a play into what kind of air conditioner you should purchase such as is the room sunny all day? How many people will be in the room at a time? How tall is the ceiling? Is the room in the kitchen or other hot appliance? All of these are signs that you need to increase the BTUs for your air conditioner.

The MRCOOL Ductless Systems come in a variety of sizes. To give you a better idea of what square footage they all fall under we’ve broken it down for you below. Just keep in mind folks that if you have some of the exceptions we mentioned above that you will need to increase the BTUs required.


This product is marketed as a do-it-yourself project. While that is great and doing it yourself can save you a bundle when it comes to hiring a professional HVAC technician, you should know exactly what you are getting into before you purchase. Doing it yourself doesn’t mean it’s going to be easy and if you guess your way through it then you not only risk voiding your warranty but you could also end up harming yourself or others when it comes to the electrical work. If you do wish to install the unit yourself then please continue reading on exactly what will need to be done.

First, the good news is that everything is included in the kit including a detailed installation manual. This manual can also be found at the bottom of this article under our ‘Important Link’s section if you wish to view an online copy. It should be noted that this kit does NOT come with exterior mounting brackets and superficial coverings. If you wish to go this route you will have to purchase these extra. The right brackets and coverings though can easily be found on Amazon by clicking here for the brackets and here for the coverings. The coverings are more aesthetic then anything, but they can provide an extra bit of protection to your lines. It is up to you if you want the extra expense or not.MRCOOL DIY Series Ductless Mini Split Air Conditioner & Heat Pump1

Now, for the install there are four main sections that will have to be done. The first two are the easiest. When you order this product you will receive an indoor section and an outdoor section. The outside section can either be mounted against your home using support brackets or it can be installed at ground level as long as you create a completely level floor pad. Most folks opt for the floor pad option as it is overall easier to install this way and if you have to do maintenance on the unit down the road you will have much easier access. Creating the floor pad can be done with bricks, cinder blocks, or even your own concrete pad.

The inside unit will need to be mounted up against an exterior wall. Some folks have done interior walls, and while yes it is possible… I would not recommend it. Remember, that once the interior section is mounted you will need to connect the refrigerant pipes and the condensation line to the outside unit. This is why it makes sense to have them on the other side of the wall.

When mounting the interior unit be sure to mount it high up against the wall, close to the ceiling. This is done for two main reasons. The first is that the fan or blower is located at the bottom of the unit. So, the higher the unit is mounted in the room the more easily the air can be distributed. If you have it towards the bottom of the room then all your cold air is blowing up against the floor. The other reason is the condensation line. This is where the water will drain through when excess humidity is removed from your home. This line is gravity fed so if your unit is floor level that water will have nowhere to go.

Alright folks so now we have the easy parts covered. The next point, and a tricky point for a lot of folks, is feeding the refrigerant and condensation lines through your home and connecting them to the exterior section. In order to do this you will need to cut a three and a half inch hole in the wall nearby where you have chosen to mount your interior unit. This is where you will feed the lines. When planning this out you should note that the MRCOOL unit comes with twenty-five feet of refrigerant line. To some this amount of piping is a blessing and to others a cruse. If you only have about ten feet needed then you have to be creative and find a way to ‘hide’ the other fifteen feet.

This unit from MRCOOL comes precharged with refrigerant. What that means is that the system is ready to go and no vacuuming or charging of the system is required. While this is a great pro it can also be a detriment as you have to be extra careful when routing these refrigerant lines through the hole and to the outside unit. Make no mistake, this is the hardest part of the install. You can NOT bend the lines. You can NOT cut or modify the tubing. If any of this occurs and a crack or leak forms in the tubing then all of the refrigerant will leak out and you will have a useless machine. If this does happen then you need to identify the source of the leak, patch it, and then charge your system again with refrigerant. You will most likely need a HVAC professional’s help in this scenario. But, hopefully it doesn’t come to this and you are very careful with the piping.

Once the tubing has been routed through the hole and both sections have been mounted you are now ready to seal the three and a half inch hole we made earlier. A lot of folks used weather proof insulation. I like the spray foam that expands. Either way, you need to seal this hole up to prevent drafts, water, and anything else from getting in there.

Alright folks, the last section of the install is the electrical portion. The twelve-thousand BTU unit requires a one-hundred and ten connection whereas the larger sizes require a two-hundred and twenty volt connection. Please note that regardless of what size of ductless system you choose it will have to be hardwired to your circuit box either through a one-hundred and ten or a two-hundred and twenty volt connection. Now, I’ll be completely honest with you here folks, I do not have much electrical expertise and it would be wrong for me to steer you a certain way for the install. From my research though I have found that you need a fifteen amp breaker for the smaller twelve-thousand unit and a twenty amp breaker for the larger sizes. Now, as to how to install these and connect them I am not knowledgeable enough to guide you. If you are not familiar with how to do this then I would recommend reaching out to an electrician once you have the unit itself setup and ready to go. It is best not to guess with electrical work and if you do it wrong then you risk voiding your warranty… not to mention harming yourself. Electricity is no joke.

Once you have finished the electrical work and everything else is done it is recommended by the manufacturer to run the air conditioner for ten to fifteen minutes and monitor the system for leaks. If the air conditioner passes then run the heater for ten to fifteen minutes as well. Note that the heater may take longer for it to truly start up so it may be best to let it run for a half-hour or so just to ensure everything is working as it should be. For any further questions or concerns when it comes to installation please click here to be taken to the official Mr Cool’s installation instructions. This should answer any questions that you have BEFORE you purchase.

Now that we have the sizing and installation sections covered we can begin to look at exactly what these products from MRCOOL have to offer. The first and most important point here is to recognize the various modes that these units come with. Each mode is important and can help you in making your purchasing decision. These units come with an Auto mode, a Cool mode, a Fan mode, and a Dry mode (Dehumidifier). Let’s take a look at these:

  • Cool – This is your air conditioning mode and can cool your home all the way down to sixty-two degrees. Although most folks prefer temperatures between sixty-eight to seventy degrees. This cool mode will work to cool your home even when outside temperatures range from five degrees to one-hundred and twenty-two degrees Fahrenheit.
  • Heat – These units from MRCOOL also come with a full heating mode. What is most exciting about this feature though is that the heater’s BTUs are mostly aligned with the air conditioners BTUs. What I mean by this is that in other air conditioners/heater combos you see the air conditioner has a significantly higher BTU number then the heater. This results in a far less powerful heater and requires you to have supplemental heat in your home along with this heater. But, with these units from MRCOOL the heater is very close the air conditioner BTUs. This heater will also work at maximum capacity with temperatures as low as five degrees Fahrenheit. Anything below five degrees then the heater will work but it will see diminished capacity.
  • Auto – The auto mode is pretty self explanatory. This is similar to most homes with a central system that have an auto mode. All this does is determine if the heater or air conditioner needs to be on. It will actively monitor the temperature in the room and turn one of these on to reach your desired temperature level. This is more of a hands off approach. I’ve never been a fan of auto myself. I like to have ‘heat’ mode in the winter and ‘cool’ mode in the summer, but that’s just my personal preference.
  • Dry Mode – Dry mode is actually just a dehumidifier mode. This allows you to dehumidify your home without cooling your home. I’m not sure how often you would use this as the air conditioner itself is a dehumidifier as well and most of the time if you are trying to dehumidify then you needing to cool as well. This dehumidifier will work between the inside temperature range of fifty to ninety degrees Fahrenheit. Outside temperature range between thirty-two to one-hundred and twenty-two degrees Fahrenheit.
  • Fan – The fan mode is just that. It is a fan without any cooling or heating effects. This is just the blower of the interior running and circulating air. This may be great to have if you have a fire in the fireplace and don’t necessarily want the heater on as well. The fan will help circulate the warm air without kicking that heater on.

Other Features

Along with your other basic modes that we mentioned above there are some other ancillary features that come with these Mr Cool air conditioners. These aren’t huge features but still good to know. The first is what’s known as the auto-restart. Let’s say for example it’s in the middle of summer and a bad storm rolls through the neighborhood and cuts power from your home. When power is restored at your home then your MRCOOL unit will turn back on and at the same settings it was at before. This is one less thing that you have to worry about resetting when your power comes back on.MRCOOL DIY Series Ductless Mini Split Air Conditioner & Heat Pump1

Another neat feature is what’s known as ‘louver angle memory.’ What this means is that when your appliance is turned off and then turned back on it will automatically remember the angle of the louvers from when it was last shut off. This is similar to the power loss feature we mentioned above. It ensures consistency when powering on your air conditioner.

This next one will be very important for those of you who elect to install this product yourself. Remember how I said earlier that you had to be very careful with the refrigerant lines and that you were not to bend them? If worse comes to worse and you do get a leak in your system the MRCOOL unit will actually alert you of said leak. If a refrigerant leak is occurring you will get an ‘EC’ error message come up on the inside unit. As to how to find the leak that is a whole other story. I did an article on this topic a few years ago which can be found by clicking here.

This product from MRCOOL comes with a remote and built in WiFi. The WiFi allows you to connect your phone to the appliance through the MRCOOL application. From here you have your own personal remote on your phone that will allow you to adjust temperatures, modes, and any other settings you require. The remote gives you the same functions as the phone app does but is overall easier to operate.

There are two extra features though on the remote though that I want to point out. The first is what is known as the ‘Follow Me’ function. This option will actually have the MRCOOL appliance read the temperature in the room where the remote is. So, if you have the inside unit setup in your living room but the remote is in your kitchen then it will keep running until the desired temperature is reached within the kitchen. This is a handy feature as it will give you a degree of separation between the cold air blowing and the thermostat itself. Otherwise, you will have the thermostat right next to where the cold air is coming out.

The last feature I’ll mention here is what is known as ‘Sleep Mode.’ This sleep mode is only accessible through the remote. When this is turned on the product will slowly adjust the temperature up or down every hour depending on if it’s in cool or heat mode. It will hold these temperature for seven hours and when the time is up it will revert back to it’s previous programmed temperature. This is a great function for you folks who want to save on your energy bills.

A lot of the pros on this product we have already covered in our product feature section, so there may be some repetition here. The biggest pro on these MRCOOL products are the various modes and the capacity of these modes. What I mean by that is you have a fully functioning air conditioner and a fully functioning heater that can work in temperatures as low as five degrees and up to temperatures of one-hundred and twenty-two degrees. This product has you covered. The only exception I would say is that if  you live in the far north and experience temperatures way below zero routinely throughout the year. Otherwise, this unit can handle whatever you throw at it.

The other big pro here is the warranty on the unit. These products come with a five year parts replacement warranty. Along with this you also get a seven year replacement warranty on the compressor. This keeps you covered in case of any your parts fail. The extra two years on the compressor is great as well as compressors are some of the most commonly failed parts when it comes to air conditioning. This warranty is much better then the competition. If you look at the Pioneer ductless system you will only find a two year parts warranty. Quite the difference if you ask me.

This warranty is NOT voided if you install this unit yourself. Remember folks, this is a do-it-yourself product. The only caveat here is that if you guess you way through the electrical work then you could void the warranty. If you are unsure on how to do the electrical connection then I would hire a professional to ensure you warranty stays in tact. For more on MRCOOL’s warranty click here to be taken to their official warranty page.MRCOOL DIY Series Ductless Mini Split Air Conditioner & Heat Pump1

The last pro I want to mention here is the overall volume of the unit. For those of you who have experience with window units you will know just how loud they can get during operation. You will not have this problem with this ductless system. No, these units are extremely quiet. In fact many folks don’t even realize the machine is on. It is that quiet.

We are now ready for the cons of this ductless system. Before I get into this though I first want to state that overall this is a great product and the cons I mention below are similar to what you find with other ductless systems. The big con here, especially on this MRCOOL system, is the expense. These units are very expensive, especially compared to some of the competing lines like the Pioneer model we mentioned in our pros section. The difference though is that with the MRCOOL brand you are getting a fully functioning heater whereas with the Pioneer you don’t get that same function. You also have less heater operating temperature range with the Pioneer unit. So, while this is more expensive you are getting more product and a higher quality product.

The other big con here is the install. Now this can be said with any ductless system. Do not be fooled, these are not an easy install. You have to mount both units. You have to feed the lines through… and you have to create a three and a half inch hole in your exterior wall. On top of all of that you have to connect it directly to your circuit breaker. Do you feel comfortable with all of that? If so, then this won’t be a big deal at all. But, if you are not then you either may want to hire a professional to help with the install or purchase a window or mobile unit that is much easier to just plug-in and go. The problem with the window/mobile units though is that their capacity is much lower and they are an eyesore.

The last few cons I want to mention are somewhat minor but still deserve to be mentioned. Some folks have stated problems with leaking refrigerant. While this can be a huge problem and will cause your unit not to work… it is most likely caused by poor install. They most likely bent the pipes or did something else to cause a fracture in the pipes which caused the refrigerant to leak out. Just be careful during install and follow the directions carefully. If you do this then you shouldn’t have this problem.

Remember the ‘follow me’ function we mentioned earlier? There were a few reviews that stated this wasn’t working properly. I only saw this a few times during my research, but the complaint was that the follow me function would try to reach the desired temperature through heat and cool in a back and forth fashion. In other words, if the temperature was set to seventy-two then cool would kick on to get it down to seventy-two… but then it accidentally goes down to seventy-one, so then the heater kicks on to get it back to seventy-two and then that accidentally goes to seventy-three. And so on and so on. This didn’t seem to be a prevalent complaint though so I don’t know much stock I would put into this.

The last con here is that some of the ductless systems are what’s known as a multi-zone system. This means that you can have one outdoor unit and multiple indoor units to cool your home in different rooms. These MRCOOL systems are NOT multi-zone. You only have one indoor unit and that is all you can have. If you need more then one then you will have to purchase the entire machine again.

Alright folks so we have gone through sizing, installation, features, pros, cons, and everything else there is to possibly know about this product. Bottom line is that this is a great product and will definitely do its job of cooling your home, garage, loft, workshop, or whatever other area you are looking at this for. But, don’t just take my word for it. If we look at we can see that this MRCOOL product has over two-hundred reviews on it all with an average rating of four and a half stars. That is the equivalent of a ninety percent approval rating. It is a solid product. If you’d like to purchase this unit please click here to be taken to our Amazon partner.

One last point of note here is that we here at RefrigerantHQ are not responsible for the install of this unit. If you purchase this product the installation process will be solely on you or a hired professional. If you are unsure on what to do rather it be through routing the refrigerant lines or doing electrical work then it is always best practice to contact a professional. You know what they say, it is always better to be safe then sorry.

Thanks for reading and I hope this review was helpful,

Mrcool Mini Split Review_

Table Of Contents_

Having an air conditioner in your office or building is essential to your overall well being, especially if you live or work in a place where the weather changes all the time. To ensure that you get the kind of good air quality that is essential for comfort, you need to invest in a good quality air conditioner. The Mrcool mini split ductless air conditioner would make a great choice, as it’s got a decent SEER rating of 22, and features technology that doesn’t eat too much into your energy costs. If you’re shopping around for the best ductless mini split air conditioner, then the DIY-12-HP-115B25 Mrcool mini split AC unit should be among your top considerations. Get through to the end of this review to find out what it’s capable of doing for you.

Why We Like It – Mrcool Mini Split

The Mrcool Mini Split air conditioner is a great option to consider especially if you’ve got spaces that average around 500 square feet in size. With a 12000 BTU rating, the AC unit is sufficiently powerful to cool down the average living room space, and since it also features a heat pump, you will be able to use it to warm up the air whenever it’s too cold.


  • Supports use of Amazon Alexa & Google Assistant
  • High SEER rating of 22
  • 7 Year Warranty on Compressor & 5 Year Warranty on Parts


Each indoor unit in the Mrcool ductless mini split air conditioner is capable of cooling a room that’s as large as 500 square feet, and this is thanks to its 12000 BTU rating. This makes it significantly more powerful than the SENL-09CD Senville mini split air conditioner, but they both rely on inverter technology, and this makes them efficient in how they function.

Energy Efficiency

The Mrcool mini split air conditioner is very much energy efficient. It’s got an SEER rating of 22, (making it better than the WYSO 12A-19 Pioneer Mini Split which has a rating of 19) and if you’ve never heard of an SEER rating before, this is basically a measure of the air conditioner’s efficiency in a year, and it gives you an indication of how expensive it is to maintain. Any rating that’s above 13 is considered to be good, and any over 20 is considered great.


As with most modern air conditioners, the filters on the Mrcool mini split air conditioner are removable, and also easy to wash. The recommended period for replacing filters is every 2 to 3 months, and this is important to take note of because it affects the quality of air conditioning. The filters trap any foreign elements in the air, and also improve its odour.


The 5 year parts, 7 year compressor and 1 year remote control warranty policy that comes with the Mrcool Mini Split is impressive, but it doesn’t match the one you’ll get with the Daikin 12000 btu mini split air conditioner. Daikin offers a 10 year parts warranty and another 10 year replacement compressor warranty, making it slightly more viable than the Mrcool AC in terms of longevity.


For added convenience and easier operation, this Mrcool air conditioner comes with support for use with both Amazon Alexa and Google Assistant out of the box, so if you don’t have it’s remote control nearby, you’ll still be able to use your phone or your voice to change the settings on it.

Mrcool Mini Split Wrap Up

As a company that was established in 2014, Mr cool still remains a new entrant to the air conditioning space, but for the few years that it has been around, it’s gained a lot of popularity for the quality of its products. The DIY-12-HP-115B25 DIY is just one of their many mini splits that have gone on to gain a lot of popularity among buyers, and if you have a look at it’s Amazon page, there are a lot of positive comments about it that people have been able to leave.

MRCOOL DIY Ductless Mini-Split Heat Pump On EBAY
Mr Cool Mini Split heat pump is a good unit that works very well both heating and cooling.

Do-It-Yourself type individuals will find it to be the simplest to install.

There is no need to buy and operate HVAC gauges or vacuum pump which many find confusing.

While easier to install it does cost more compared to other DIY kits.

I installed a Mr Cool unit on my garage 1 year ago (See video below) and it has been working very nicely heating in the winter and cooling in the summer.

The unit heats and cools very well with a remote control that makes it easy to operate.

The 17.5 SEER rating is also very good and makes it a very efficient unit.

There are higher SEER units that can be bought but 17.5 SEER is a good SEER rating.

My thoughts on Mr Cool units is once installed they work very well.

They are good for the DIY type person that doesn’t want to buy and operate HVAC gauges or vacuum pump.

For a more experienced DIY type person there are cheaper kits that while harder to hook up cost less.

Read Here for an Overview of All the Mini Split Kits I Have Installed.

I am still testing the unit so far with good results and will update if anything changes.

As always be sure to read the reviews on Amazon, forums, or elsewhere to be sure a unit is a good fit for you.

For a long time, the HVAC industry has been dominated by a few large manufacturers. Their brand names are well-known and highly regarded.

But a new company called Mr. Cool has now entered the HVAC field, and they are already making quite a splash. If you’re in the market for new heating and cooling equipment, you owe it to yourself to check out their products before you make your purchase.

This is certainly true if you’re looking for a mini-split heat pump, which is a Mr. Cool specialty.

How Mr. Cool Mini-Split Compares to the Competition

Modern mini-split heat pumps are manufactured with energy-efficiency in mind. Consequently, no matter what brand you choose your SEER (seasonal energy efficiency ratio) ratings for cooling and HSPF (heating seasonal performance factor) ratings for heating will be impressive. Also, most units now come with remote controls and electronic control panels that allow for precise digital interface and customized hour-by-hour programming.

What Mr. Cool has done is to take these concepts to another level. By incorporating industry best practices, they’ve created a heating and cooling system that hits every energy-efficiency bullseye available. Surpassing the improved mobility offered by the remote control, they’ve manufactured superior-quality smart appliances that are WiFi compatible. Once you’ve installed the Mr. Cool app, their DIY mini-splits can literally be monitored and controlled from anywhere on the planet.

But the most innovative characteristic of their DIY line of mini-splits is the DIY part. With a few basic tools and help from one or two family members or friends, you can install your new Mr. Cool all on your own in just a few hours time. This can save you an enormous amount of money on labor, more than enough to offset the higher upfront cost of a Mr. Cool DIY appliance.

People Also Ask

Here are the questions:

How Many Amps is a Mini-Split?

A typical mini-split heat pump will seldom draw more than 20 amps of power and usually will use much less since they aren’t normally operated at full capacity. This makes them more energy efficient than most central air conditioners or ducted heating systems.

How Many BTUs Do I Need in a Mini-Split?

Recommendations will vary between manufacturers, but some reasonable estimates might be:

8,000 BTU for 350-450 Square Feet
12,000 BTU for 500-700 Square Feet
18,000 BTU for 700-1,000 Square Feet
24,000 BTU for 1,000-1,250 Square Feet
36,000 BTU for 1,250-1,700 Square Feet

Rooms that are unusually warm because of sunlight penetration or proximity to a kitchen might need more heating capacity.

How Many Watts Does a Mini-Split Air Conditioner Use?

The power consumption of a mini-split unit varies by its heating and cooling capacity. It’s reasonable to expect a 12,000 BTU ductless heat pump to use 1,000 watts of electricity or more when turned on, while a 24,000 BTU model could be expected to use twice that amount.

Mr Cool DIY Mini Split Buying Guide

If you’d like more information before purchasing a mini split, this Buying Guide with FAQ’s will provide you with some answers.

Who is MRCOOL?

MRCOOL was founded in 2014 and is headquartered in Hickory, Kentucky. It’s rise to becoming one of the top mini split heat pump brands has been swift. MRCOOL is known for its durable, reliable mini splits highly recommended by HVAC professionals. They are also the first heating and cooling manufacturer to make ductless mini splits that are truly DIY and can be easily installed by the homeowner without the need for specialized tools.

MRCOOL was a finalist in the Innovation category at the 2021 AHR (Air Conditioning, Heating, Refrigeration) Expo for their ground-breaking approach to ductless mini split DIY installation design which eliminates the need for in-field vacuuming and charging by an HVAC professional.

What is a Mini Split Heat Pump?

A mini split heat pump provides air conditioning, heat and dehumidification. The mini split name comes from the fact that they have two major components, the condenser is installed outside and one or more air handlers are installed inside. A mini split does not require ductwork.

There are single zone units that include the condenser and one air handler and multi-zone units that include the condenser and two to four indoor air handlers. Mini splits are available in a variety of BTU levels.

Why Purchase a Mini Split?

There are a variety of excellent reasons to consider a mini split. Following are some of the best reasons:

When you want to cool an area that doesn’t have existing ductwork. A mini split system is a great option for a home that uses radiant or hot water heating, but where part of the house isn’t adequately served.

A mini split can be used to supplement an existing system. Perhaps you have an area of your home that your existing system can’t keep comfortable, like an upstairs bedroom or basement. A mini split can supplement your existing system to make the area comfortable and without much added cost.

When you add new space to your home. Mini splits are perfect for additions and attic conversions and will save you the cost of adding expensive ductwork. Plus, your existing central HVAC system likely won’t have the capacity – if properly sized – to heat and cool the extra space in addition to what it’s already doing.

When you want to customize temperature control in individual rooms. Multi-zone mini splits allow you to control the temperature in each room or zone. The indoor air handler in each room is operated with its own thermostat and control.

You may need extra cooling in the kitchen during the day and more cooling in the bedroom at night. They are also good for a room that you only use occasionally, like a guest room. Using energy only where and when you need it will save you money on your energy bills.

Mini splits are excellent solutions for spaces where a central system isn’t possible. Mini splits can be used for heating and cooling  tiny homes, cabins, garages, offices, workshops, pole barns and even RVs.

What Size Mini Split Do I Need?

Knowing how many rooms you want to cover and their overall square footage is a good starting point. If you need a multi-zone system, consider whether the air handlers will always run simultaneously or not. Other factors include the layout of the space, the age of your home, and how well it’s insulated.

Note: For multi-zone units, the total BTUs of the condenser will be split between the air handlers in use at any given time. For instance, you can have a 27k BTU condenser with three 12k air handlers but they won’t all run at 12k at the same time. This would be a good choice if you only need two handlers running at full capacity at the same time.

MRCOOL mini splits are available with 12k to 36k BTU condensers and with one to four indoor air handlers. Below is a guide to BTUs and coverage areas.

Can a Mini Split System Save Money on Energy Bills?

Yes, a mini split heat pump system can save you at least 30% on energy costs over window air conditioning units and central systems. Here’s why:

Heat transfer abilities. When in heating mode, mini splits transfer heat from outside into your home. They don’t generate it. As a result, they generate on average about three times more heat compared with the energy used. The most efficient furnace available now is the Lennox SLP98V with an impressive 98.7% fuel utilization efficiency. You could state the performance as a ratio of .987 to 1; for every unit of energy spent, you get .987% of it in heat. By contrast, ductless heat pumps average about 3.5 to 1. For every unit of electricity spent, they deliver 3.5 times more heat. This is called the Coefficient of Performance, or COP, if you’d like to do further research.

They are ductless. Mini splits do not lose cooled or warmed air through ductwork, like central systems do.

Did you know? In homes with older ductwork, an average of 30% of the treated air, whether it is heated or cooled/dehumidified, escapes through gaps and poorly insulated sheet metal. So, if you have a 95% gas furnace, it is suddenly reduced to a 65% furnace. This is one very important reason that ductless mini split heat pumps are growing in market share year after year after year.

Temperature customization. Mini splits allow you to tailor climate control in individual rooms at specific times. The entire house doesn’t have to be the same temperature at the same time.

Innovative technology. MRCOOL mini splits use technology that makes them extremely efficient, offering many units with SEER Ratings above 20. SEER stands for Seasonal Energy Efficiency Ratio and can be used as a guide to let you know how much comfort you get for every energy dollar you spend. The higher the SEER, the more efficient the unit.

A SEER rating above 17.5 is considered excellent.

EnergyStar. Many of the MRCOOL mini splits are EnergyStar certified meaning that they meet strict energy efficiency criteria set by the U.S. Department of Energy and are at least 25% more efficient than non-certified products.

Replacing older systems with an EnergyStar product can often make you eligible for a rebate from your local energy supplier. Really? Yes, really. Call your energy provider or check its website. If you want to explore this more, our partner contractors will give you full details on the savings for various heat pump models. Call 888-894-0154 or click here for details.

What Other Features Are Available?

The MRCOOL DIY mini splits include a Smart HVAC App, compatible with Google, Alexa, Apple, and Android, and include WiFi remote control. Install it on your phone, and monitor and control the thermostat from anywhere. This can save you a lot of money in a year. In summer, turn up the thermostat to 80 while you’re gone to save on energy costs. Then about an hour before you plan to get home, use the app to turn it down to 74, and the space will be cool, dry and comfortable when you arrive.

  • Low coolant and filter change alerts.
  • Follow Me Mode tracks the air temperature at the location of the remote. Think about that. If you keep the remote near you, then the unit won’t stop working until the remote – and you – are as cool or warm as you want to be.
  • Sleep Mode
  • Low ambient cooling capabilities for rooms that need cooling year round like server rooms and greenhouses.
  • Auto Restart will retain all of your programmable information in the event of a power outage.
