The 18k BTU MrCool DIY 3rd Gen Ductless Air Handler with a compatible MrCool DIY condenser is a legitimately do it yourself heating and cooling option. This air handler has an 18,000 BTU capacity and can heat and cool up to 750 square feet. And, as we said before, only a MrCool DIY air handler is uniquely designed for amateur installation.

With MrCool, interruptions to your daily life are kept to a minimum. With this smart system, there is no need to reset the horizontal louver to ensure your home is evenly cooled or heated. The 18k BTU MrCool DIY 3rd Gen Ductless Air Handler remembers where you set the louver and automatically goes back to that position once it is turned back on.

This indoor wall unit offers several modes and features to make sure it operates just the way you want for your home.

In AUTO mode, the unit will automatically select cooling, heating, or fan-only operation based on the set temperature and the temperature of your room so you don't have to constantly monitor the temperature of your home.

In SLEEP mode, the temperature will increase 2°F per hour when cooling and decrease 2°F per hour when heating during the first two hours of operation. It continues at that new temperature for six hours, then returns to its normal operation. This allows you to fall asleep comfortably and save money while you snooze.

By using the TIMER feature, you can limit your energy usage and save money on your electricity bill.

This air handler also offers a DRY mode that will regulate the temperature and dehumidify at the same time by switching between the cooling and fan-only operations.

Keeping on top of your air handler's maintenance is easy with the 18k BTU MrCool DIY 3rd Gen Ductless Air Handler. The wall unit can let you know when your HVAC is leaking refrigerant, prevent mildew growth with the Anti-Mildew Function, and remind you when the air filter needs to be cleaned or replaced. The MrCool DIY 3rd Generation will also auto restart in the event of a power outage. So you don't have to lift a finger to get your home to a comfortable temperature when power returns.
