In Roanoke, heat pumps can be a popular solution for heating and cooling your home.
They appear very similar to an air conditioner. In actuality, they run in the same way during warm weather. Because of a reversing valve, they can shift heat in the opposite direction as well as add warmth to your residence when temperatures drop.
Not sure if you use a heat pump or an air conditioner? Just track down the model number on the outdoor unit and check it online. If you find you have a heat pump, or you’re thinking about purchasing one, learn more about how this HVAC unit keeps houses comfy.
How Heat Pumps Operate
Heat pumps depend on a refrigeration system much like an air conditioner. Most can run similar to a ductless mini-split, since they can heat and cool. Heat pumps have an indoor evaporator coil and an outdoor condensing coil. Refrigerant is sent through these coils to move heat. The outdoor unit also contains a compressor and is surrounded by metal fins that function as a heat sink to help shift humidity efficiently.
When your heat pump is set to cooling, the refrigerant is in the evaporator coil. Air from indoors moves over the coil, and the refrigerant removes warmth. Water in the air also condenses on the coil, dripping into the condensate pan below and drains away. The resulting cool air moves through the ductwork and back into your residence.
Meanwhile, the refrigerant flows a compressor on its way to the outdoor coil. This compresses the refrigerant, leading it to warm up. As it flows through the condensing coil, the outside fan and metal fins help to discharge heat to the outside. The refrigerant heads back into your house, traveling through an expansion valve that cools it significantly, preparing it to go through the process from the start.
When your heat pump is replaced and maintained correctly, you’ll enjoy efficient cooling as good as a high-performance air conditioner.
When your heat pump is set to heat, the heat exchange cycle happens the opposite way. By moving in a different direction, refrigerant removes heat from the outdoor air and disperses it into your house to warm the inside.
Heat pumps working in heating mode are most effective when the temperature remains above freezing outside. If it turns too cold, a backup electric resistance heater kicks on to keep your home comfortable, but your heating bills go up as a result.
Heat pumps operate longer than furnaces since the air doesn’t turn as heated. This helps keep a more even indoor temperature. On top of that, because heat pumps transfer warmth rather than making it from a fuel source, they can work well above 100% efficiency. You should receive 30–40% savings on your heating costs by switching to a heat pump.
