We are thrilled to announce our new 5th Generation MRCOOL® DIY® 18k BTU Multi-Zone Ductless Mini Split Condenser, which is the best and most convenient way to get comfortable. You won’t need the services of an HVAC professional to install this unit, because it’s do-it-yourself! Achieving a SEER2 rating of 23.9 and an HSPF2-4 rating of 10, you can rest easy knowing this unit will help you save money as you chill. This condenser can also support up to three air handlers, meaning it can heat and cool three rooms that are a combined 750 square feet in size, making it a perfect option if you have spare bedrooms in need of heating and cooling.
What makes this system different is our patented pre-charged Quick Connect® line sets filled with R-454B, an incredibly efficient and eco-friendly refrigerant. This switch from the previous refrigerant makes the system even more efficient and sustainable than before. The design of these innovative line sets allow you to install the system yourself, saving you time and money.
This condenser is more than just a heating and cooling unit. When operating as a system, you will be able to experience total customization with the unit’s wealth of features. For example, you can integrate your system with Amazon Alexa or Google Home through the Smart HVAC app, allowing you to control your system with your voice and monitor its operation with the touch of a button. You can also set schedules, temperature ranges, and mode of operation through the app. The power of comfort is in your hands with this system. In the unlikely event that something happens to the system, we’ve got you covered. The DIY® series comes with one of the best warranties in the industry - a 7 year compressor warranty, a 5 year parts warranty, and a Limited Lifetime Replacement warranty with enrollment in the MRCOOL® Care Program. Give yourself the best comfort with the DIY®.
