Large commercial spaces, such office buildings, retail stores, and industrial facilities, can benefit from both heating and cooling provided by a commercial heat pump, a sophisticated climate management system. A heat pump employs a single mechanism to handle both heating and cooling, in contrast to traditional HVAC systems, which normally run with separate heating and cooling units. Transferring heat instead of creating it is the fundamental idea of a heat pump. No matter the outside weather, a heat pump can effectively keep the interior of a building at a reasonable temperature by transferring heat using refrigerant.
