Until recently, I’d never heard of a VRF heating plus cooling system. I was respected with oil furnaces, boilers, heat pumps plus air conditioners, but variable refrigerant flow systems were modern to me. An Heating plus A/C supplier recommended this type of system when the two of us renovated our house plus tore out the forced air equipment. The air duct was a complete mess plus the oil furnace plus air conditioner were terribly aged. The people I was with and I got stuck breaking down walls plus ceilings plus creating a large mess. The method of putting in a similar system didn’t appeal. I’d had enough of leaky ducts wasting energy plus spreading dust throughout the house. I wanted something easy plus more compact, and vRF technology is a lot like a ductless split system in that there is a single outdoor condensing component attached to several indoor units. However, as the name implies, a VRF system features inverter-driven fans that adjust the speed plus refrigerant flow to meet the exact plus changing demands of each particular room. Plus, the VRF system can handle simultaneous heating plus cooling. It can heat one room plus air condition another, however even better, the system provides heat reusey. It takes the heat it captures during the cooling process plus redirects to the room that requires heating. The result is incredible energy efficiency. I’ve trimmed my annual utility costs by around 30%. I also like that the VRF system allows for truly precise temperature control, operates quietly plus allows flexibility of design. If the two of us should decide to put an addition on our house, the two of us could add more indoor units without any major problems.
