 Over the last 20 or 30 years, heat pump technology has continued to evolve, and today, homeowners can choose from a variety of systems that best fit their needs. The VRF, or Variable Refrigerant Flow Heat Pump, is a heating and cooling system that does not have duct work as a component of the overall system. They serve as a great application for homes and living spaces where installing duct work is not possible or desired. Commonly known as a mini-split heat pump or ductless heat pump, the VRF system uses a single outdoor condensing unit to connect with one or more indoor air handlers. Refrigerant is cycled through the lines from the outdoor condensing unit to the air handlers, where the heat or cool air is distributed. Typically, the indoor air handlers can be mounted on the wall or ceiling and come in a variety of styles. Each zone has its own thermostat and when needed, multiple air handlers can be controlled as separate zones, providing the right amount of heat or conditioned air for that zone. In addition, both heating and cooling can occur at the same time. So if the bedrooms in the back of the house need cool air, while the front of the house requires heat, the system can handle it. As with other heat pumps, there are significant energy savings, but the VRF system provides some added efficiencies. There is minimal energy loss compared to 30-40% energy loss with traditional forced air systems that use ductwork in unconditioned places, such as attics. And in most circumstances, VRF heat pumps do not require a backup heat source. Whether it's a new sunroom or retrofitting an entire house, if ductwork is not an option, a VRF heat pump is the perfect option. Energy smart choices brought to you by Georgia Power.
