| 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. These line sets are sold separately. 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®. |

My biggest hesitation was definitely the "DIY" part. MRCOOL's pre-charged line sets are truly brilliant. We chose the 2-zone system (we used one head for our living room/dining area and another for the master bedroom), and the ability to control each space independently is fantastic. The 22 SEER rating isn't just a number on a spec sheet β it directly translates into significant energy savings.
I used the two heads to finally tame the wild temperature swings in my garage workshop and my bonus room above it. They now run independently, silently, and efficiently. The temperature control is instantaneous and the Wi-Fi monitoring is solid. When a friend asked who installed my new AC, the look on their face when I said "Me" was worth the price alone. This isn't just an air conditioner; it's a giant middle finger to overpriced HVAC quotes. If you can handle basic wiring and drilling a clean hole, this is your solution.
I skipped the pro install and saved thousands. The indoor units are whisper-quiet and cool the rooms instantly.The pre-charged lines made the setup foolproofβno special tools needed. Controlling both zones from my phone is a total game-changer
