These units were noisy and not especially energy efficient, so it is not surprising that one of the most common problems we feel is noise. However, modern mini-divisions are different. They are much quieter than original models, due to much of the technological progress.

Hyper-heat systems offer 100% heat capacity in outdoor 5 F environment, and offer performance in outdoor -13 F environment, so they are the perfect complement to an existing central heat system.

Finally, the HVAC-free mini-units are controlled individually at each location while conventional systems are controlled by one or two thermostats that control the whole house or workspace.

Most wall units require gravitational drainage, where other types of units (cabin, roof or floor) can incorporate a condensate pump installed in the factory or provide the possibility of a condensate pump supplied on the floor.

Mini-splits are heating and cooling systems that allow you to control temperatures in individual rooms or spaces. Mini-splits are equipped with two main components: an external compressor and an air handling unit (evaporator).
