Since the DIY Multi-Zone is a heat pump, you get great cooling and heating without running up that electric bill or harming the environment. The outdoor heat pump unit is capable of heating up to 36,000 BTU.

The 9,000 BTU air handler can distribute heated or cooled air in a room of up to approximately 250 square feet.  

Installing the MrCool DIY 36k BTU 21.5 SEER 4-Zone Ductless Heat Pump Split System - 9k+9k+9k+9k does not require any special training or tools. You only need a basic technical ability and follow directions to install. The Quick Connect line set is a special pre-charged line that makes installation simple. It allows anyone to complete this home improvement project in record time.

The MrCool DIY 36k BTU 21.5 SEER 4-Zone Ductless Heat Pump Split System - 9k+9k+9k+9k can heat, cool, and dry. The LED display on the front of the air handler allows you to check the temperature of your space easily. You can also monitor your home heating and cooling system using the MrCool mobile app (available for iOS and Android devices). Control the unit from anywhere with the included remote, the MrCool smartphone app, or an Amazon Alexa or Google Assistant.

Both MrCool air handlers included in this MrCool DIY 36k BTU 21.5 SEER 4-Zone Ductless Heat Pump Split System - 9k+9k+9k+9k evenly distribute heated or cooled air via their directional louvers, so you can stay comfortable 24/7. Sleep mode allows you to even save money and sleep soundly simultaneously. Once activated the unit moderates room temperature in eight-hour increments. In each of the first two hours in that window, the appliance will drop while heating or rise while cooling by 2°F. For the next six hours, this more moderate temperature will keep you comfortable and reduce energy costs and usage.

Use auto mode to set each indoor unit to your desired temperature and let the unit handle the rest. The MrCool DIY system will determine how much heated air or air conditioning you need to maintain your desired environment. If you require forced cooling to test the unit’s air conditioning ability or perform maintenance tasks this MrCool DIY System can be set to a manual mode, also called emergency operation mode. Push the button on the right side of the air handler under its front panel to initiate this type of operation.

Enjoy these additional options of this MrCool DIY 36k BTU 21.5 SEER 4-Zone Ductless Heat Pump Split System - 9k+9k+9k+9k that give you extra control of your home’s comfort level. Use the timer to limit energy usage and save money on your next bill. Easily read the alerts on the LED display on the front of each air handler. Examples of alerts include low refrigerant and reminders to clean or replace the unit’s filter. You can mute the air handlers if you want an interruption-free atmosphere. Mute your system to deactivate the LED display and audible alerts. During a blackout or power outage, you can trust this split system to automatically return to operation with the same settings once power returns.

Maintenance is easy with this MrCool DIY 36k BTU 21.5 SEER 4-Zone Ductless Heat Pump Split System - 9k+9k+9k+9k.
