Maybe you’re the go-to fixer upper around your house, a home improvement guru, or just enjoy continuously reinventing your space. For any kind of DIYer, we have the product for you. Introducing the MRCOOL DIY 3rd Generation Energy Star Ductless Mini-Split Heat Pump.

The MRCOOL DIY 3rd Gen provides optimal comfort in a simple-to-install format. As you may have gathered, the 3rd Gen is the latest model from our popular DIY Series, and delivers even more flexible installation options than previous models. It requires no specialized tools, no special HVAC training, and no handling of expensive refrigerant.

And, as the name implies, the MRCOOL DIY 3rd Gen is Energy Star certified. This means you save money every month on your energy bill as your DIY unit maximizes its efficiency during both cooling and heating. This serious money-saving capability makes this product ideal for additions to homes already serviced by a high efficiency central system. Additionally, the DIY benefits older homes that need to be upgraded from outdated window air conditioners or low performance baseboard heaters.

Installation Supplies

So, what do you actually need to install a MRCOOL DIY 3rd Gen E Star heat pump?

You only need basic tools like a stud finder, drill, level, 3.5-inch hole saw, and wrenches. Our easy-to-read installation manual will guide you through the entire process, step by step. Should you ever get stuck or have a problem, you can call us at 270-366-0457 to speak with Tech Support.

Smart HVAC WiFi Controls

Simple and fast installation is great, but what’s so special about the DIY after that’s done?

One DIY feature our customers love is the Smart HVAC Controller®. This tech-savvy capability allows you to control your DIY unit with your smartphone. You control everything else in your life with your phone, so why not your air comfort too?

The Smart HVAC Controller for the MRCOOL DIY 3rd Gen E Star unit is packed with great features and capabilities. You can set and change your ideal settings with the touch button. No matter where you are in the world, you will be able to control your MRCOOL DIY simply and easily. Plus, you get even compatibility with Amazon Alexa and Google Assistant.

Other Features

Other features include Low Ambient Cooling down to 5 degrees, Gold Fin corrosion resistance, auto-restart, Sleep Mode, louver position memory, Follow Me functionality, and more.

Low ambient cooling is ideal for spaces that require a set temperature 365 days out of the year. Trying to keep a server room or greenhouse cool on cold winter days? Low ambient cooling is what you need.

Gold Fin corrosion-resistant is even better. This protective condenser coating protects the coil against the corrosive effects of wind and weather. It helps ensure long term quality performance.

Auto-restart is a quality of life feature you will appreciate when you least expect it. Sudden power outages are annoying. Auto-restart means that your DIY mini-split will be back up and running in a matter of seconds when the power is out. That means if your power goes out in the middle of the night, you won’t have to move a muscle to get the air comfort flowing again.

Sleep mode is a great feature for setting when the household is quiet and sleeping at night. It helps you save money and sleep easier as your system runs efficiently to your ideal temperature setting.

Choose the louver position memory when you want your system to remember the exact settings you choose during the daytime. No need to reset your system with your choice in settings every morning. This function stores your favorite temperature, position and more so you can wake up without a worry.

The Follow Me function is designed to provide you with optimal comfort customized just for you. With previous heating and cooling technology, you would have to wait for the split system to heat or cool the entire room before you could regulate the temperature to your exact specifications.

Warranty

Last but certainly not least, the MRCOOL DIY® 3rd Gene E Star Ductless Mini-Split Heat Pump comes standard with a 7-year compressor and 5-year parts warranty. That means you can rest assured you’re making a great investment in choosing a DIY for your next HVAC system.

  1. We cannot seem to find Mr Cool 3rd Generation Energy Star 36,000 BTU DIY for our enclosed pole barn 24×36 with 14 ft ceiling. It has sprayed foam insulation in ceiling and walls, no windows, 1 entry door, 1 garage door. We are in Florida and Don’t think 24,000 btu would be big enough. We installed 18,000 last year in our Sunroom and love it. So we need DIY. Thanks for any help.

        1. We had very high sales for the DIY 36k this summer. Most dealers are sold out. However, we are working to get the model back in stock as soon as possible.

  2. Can the pipes from the air handler be routed through the right side of the unit instead of the back? We bought the E Star 24K unit.

  3. We recently purchased a 12k DIY mr cool mini split and I’m curious about what happens with the heat when outside temps reach below 20 degrees. I noticed some literature saying that it “stops working”. Does that mean that the unit will completely shut off due to the outside unit becoming too cold? Or will it still work, just not as efficiently? We have a wood stove to help heat the area as well but it cannot heat the whole space on its own, so will that help the unit stay on below 20 degrees or does the inside temp have nothing to do with it at that point?

    Hoping this makes sense:)
    Thanks!

    1. The DIY mini split will still work, but will lose heating efficiency at outdoor temperatures like 20 degrees and lower. It will not function at 5 degrees Fahrenheit or lower.

  4. Do you have any plans to make a DIY multi zone unit that is energy certified? It appears none of the DIY multi zone units qualify for the rebate in NH. New Hampshire’s rebate is $500 per ton. It’s cheaper for me to by individual units that do qualify but that does not seem to make sense.

    Thanks in advance.
