If you’re in need of comfort, our new 5th Generation MRCOOL® DIY® 27k BTU Multi-Zone Ductless Mini Split Condenser is the perfect solution! The acronym in the name is true - you can install this system on your own, without the assistance of an HVAC professional! You’ll save money in more ways than one, too, due to the incredible efficiency of this system, which attains a SEER2 rating of 23 and a HSPF2-4 rating of 9.5.
This condenser in particular is able to support up to 4 air handlers, meaning it can provide heat and air conditioning to four separate spaces equalling a total of 1,000 to 1,200 square feet. This system is unique because it utilizes special, patented Quick Connect® line sets that are pre-charged with R-454B, which is a newer refrigerant that allows the system to be even more sustainable and efficient than its previous generation. These line sets essentially link to the fittings of the condenser and the air handler, making the installation process a breeze.
Once installed, this condenser will be able to do more than you expect! Our SmartHVAC app gives you the opportunity to integrate the system with your phone and Amazon Alexa or Google Home, which will let you control your comfort using just your voice. The app also gives you the ability to customize your comfort with a range of features, from setting schedules to monitoring the system’s energy use. You deserve to have your comfort meet your standards, and this unit can do that for you. Should something happen to the system, we’ve got your back. The DIY® series boasts one of the foremost warranties in the HVAC industry - a 5 year parts warranty, a 7 year compressor warranty, and a Limited Lifetime Replacement warranty if you enroll in the MRCOOL® Care Program. Get the best for your home and install a DIY®!

*Shipping Policy
I ordered a HVAC system and it arrived in a timely manner and with no apparent issues. I thought the system was defective once installed but it was the installers fault who wired it wrong. My only issue would be the fee (30% I believe) to return a defective item within the 30 day return policy. If it is defective the customer shouldn't have to pay a fee to return an item that is not operating as designed. Other than that this is a good company.
Installed my own central HP system. It was a bit of work but nothing beyond a person with basic mechanical and electrical skills. It took me a while because I had to remove the existing electric forced air furnace from a pretty tight place. Some custom sheet metal work and a bit of custom electrical too. Worked perfectly when powered up and I actually like the thermostat provided, although I wish it was clearer how to set up a temperature set-back schedule. Pre-charged refrigerant piping was something new and I liked that too. The best thing is that my electric utility forked out $4,000 and that paid for the unit!
Installed with ceiling cassettes... Quiet and keeping us cool so far !
