What is the definition of a minisplit heatpump? A minisplit heatpump is an energy efficient heating and cooling system that is designed to provide comfort to individual rooms or zones within a larger space. It is a ductless system that consists of a single outdoor unit connected to one or more indoor air handlers via refrigerant lines. The outdoor unit is the condenser which is powered by a compressor and operates with a fan to draw air into the system and transfer it to the indoor air handler, where it is cooled or heated depending on the season. By using the refrigerant cycle, the heat from the indoor space is moved outside and the cold from the outside is brought in to cool the indoor space. Minisplit heatpumps are an energy efficient alternative to traditional heating and cooling systems, as they don’t require ductwork and can help to lower energy bills. They are also quite versatile, as they can be installed in almost any space, whether
