Mini Split Heating

While heat pumps are similar to standard mini split air conditioners at first glance, they have one extra essential function: they can both heat and cool your interior, making them a practical HVAC option year-round. However, if you live in colder climates with cold to freezing winters, you may need a more powerful model capable of delivering more heat. ComfortUp carries a wide selection of extra-heat systems ideal for the task.

Extra-heat models are heat pumps designed to function normally and keep the interior of your home comfortable even when the outdoor temperatures are freezing. ComfortUp carries extra-heat systems from Mitsubishi Electric and Gree, including the Mitsubishi Hyper Heat, Gree Sapphire, and Gree Multi+ Ultra product families. These products are certified to maintain their factory capacity and keep your home reliably warm even when the outdoor temperatures fall under -10°F. This functionality applies to all heat pumps, regardless of the number of zones and capacity. For instance, a single-zone extra-heat system will function under the same operating temperatures as a multi-zone model of the same manufacturer and product family.

Browse our collection of Gree and Mitsubishi extra-heat systems and stay warm year-round regardless of your home’s layout. Whether you need a single-zone system for keeping an apartment, single bedroom, or outdoor shed warm or a comprehensive multi-zone system for an entire home, we have an extra-heat system for you. 

Our extra-heat single-zone models feature capacities ranging from 9,000 BTU to 24,000 BTU. In contrast, the multi-zone models feature 2 to 5 zones, with capacities between 20,000 and 42,000 BTU, ideal for houses or apartments of any size.
