Heat pump overview

A heat pump is an all-in-one electrical device that heats and cools your home as desired. The heating and cooling system works throughout the year to keep your home comfortable. The working mechanism of a heat pump involves extracting heat from one place and transferring it to another. During the cold winter months, your heat pump will extract heat from the air outside and transfer it inside your home. When the weather heats up, the appliance will do the reverse, extracting heat from the air inside your home and moving it outside, so your home remains cool. There are different types of heat pumps, which include air-to-air, water source, and geothermal, as well as single-stage, two-stage, variable-speed, and modulating heat pumps.
