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®!
