What is a ductless mini-split heat pump?

A ductless mini-split heat pump, also known as mini-split or zoned HVAC, is a type of HVAC system that doesn’t require ductwork to condition your indoor air.

Ductless heat pump units can be the best alternative for home renovations and add-ons that don’t have an existing duct system in place.

When extending or installing new ducts is overly complicated or impractical, ductless mini-split heat pumps may be ideal for heating and cooling. Larger homes requiring more control over their cooling and heating may also prefer the convenience and flexibility of ductless mini-split heat pumps. By only cooling or heating the rooms in active use, you may save considerable energy and money. With more control over your temperature levels, there will also be fewer thermostat wars in your home. A ductless mini-split heat pump comprises two main components, the indoor air handling unit and the outdoor compressor or condenser unit. The indoor unit air handler, often suspended from your ceiling or mounted high on your wall, delivers conditioned air directly into your living space. The indoor unit is connected directly to an outdoor compressor unit via a refrigerant line instead of a complicated duct system. In addition to a refrigerant line, your indoor unit is also connected to your outdoor unit by a condensate drain line, suction tubing, and a power cable. The ductless mini-split heat pump includes multiple indoor air handling units connected to the single outdoor unit. These multiple indoor units can be controlled independently, but they all use the same outdoor heat pump unit to either dispense or absorb heat.
