MRCOOL is happy to announce that on 21 September 2021 it received Patent No. 11,125,479 from the United States Patent and Trademark Office. This ‘Apparatus and process for amateur HVAC installation’ patent makes the MRCOOL DIY the only ductless mini-split heat pump on the market with technology patented and verified to ease installation for nonprofessionals.

While the competition can only claim to be do-it-yourself worthy, our DIY patent proves that our technology really is.

Why Our DIY is Superior

What does the MRCOOL DIY have patented that other mini-splits just don’t?

Our Quick Connect lines are the star of the show. These lines and their integration into the overall design mean that this mini-split can be installed without the necessity of in-field vacuuming or charging. Plus, they can be easily connected without cutting or brazing. In short, this patented technology means that anyone can hook up the refrigerant lines on the MRCOOL DIY without special tools, training, or industry-only know-how.

This innovative approach to HVAC is what has allowed MRCOOL to grow into a space once dominated by giant, old money corporations. It is our conviction that tech disruptors like our patented DIY design, and others on the horizon, will change the face of this industry in a much quicker timeframe than the experts believe.

  1. I just installed the MRCOOL MDU0180124036 and air handler. The concept is fantastic, I installed in a mobile home so it was a bit more challenging. I really like it this first night of operation. Although, I dread the day I will have to charge the thing because the charging connections are situated so it will be very difficult to get my hoses on. A few other things I noted. The King valves are so close to the bulkhead that connecting the line sets is more difficult than need be. Along with that, it is very difficult to get the insulation around the “Low side” or gas tube on the A-coil. A little more clearance would make installation a little more forgiving and not so frustrating. The refrigerant line connections on the condenser are inside the front right panel and face downward. I mounted the condenser on slab next to the house. This meant the tubing had to make a 90′ bend from side to an immediate 90′ bend up, not real conducive for the “non-kink” line set. That said, the install was reasonably quick and easy. The no braze “no-vac” lines had me. I can no longer see the flame to braze correctly. That along with the 10 year warranty sold me.

  2. I have just finished the installation of a Mr Cool DIY 18,000 BTU Energy Star Ductless Mini Split Unit. The unit is the 3rd Mini-split unit I have installed in my home over the last 4 years. The first two units were each a different brand and size, the first a 24K BTU unit (a noisey unit) , the second 9K BTU in our garage (very quiet), and now for our kitchen/dinningroom/office area our new Mr. Cool 18K BTU unit. (The quietest of all) The unit was a joy to install. Your company provided superior direction manuals that were very detailed and yet easy to understand. All required part were include with a few spare items included as well. Your company’s newly patented refrigerant lines and fittings were easy to install, and all fittings sealed perfectly on the first try. I do have Torque wrenches from installation requirements for former mini-split units I’ve installed, so final steps were easily done as per your installation manual. I recognize though that for DIY home owners, your new fittings should seal well for those who do not have the torque wrenches that are recommended. Your new fittings are such an improvement for refrigerant lines. One note on your installation instructions though: I would inform installers that the new fittings do require more turns that the traditional flared fitting to get to the “snug point”. Your new fittings really seat all the way on with no visible thread to be seen as the “snug point” is reached. (old flared fittings reach that snug point much more quickly from my experience) Thus I would suggest that you inform the installer that the fitting may take a number of turns to reach that snug point, before the final wrench torque tightening of just a few degrees of turn is completed. Mr. Cool has developed a very fine product, and I hope that word of mouth will continue to provide strong sales for you company in the years to come. Congratulations to your design teams for: innovative engineering, superior shipping and packaging expertise, finely written instructions and great customer service. I can only praise you all for running such a fine organization and backing your products with the home owner in mind.

    1. Thank you very much for this thoughtful review! We’re ecstatic to hear that you’re enjoying our unit, and we’re incredibly grateful for your feedback. Once again, thank you!
