In San Antonio, heat pumps can be a popular choice to heat and cool your home.
They look about the same as an air conditioner. In fact, they work in the same way during warm weather. Because of a reversing valve, they can shift warmth in the opposite direction as well as add warmth to your house in the winter.
Not sure if you have a heat pump or an air conditioner? Simply locate the model number on the outdoor unit and run it online. If it turns out you own a heat pump, or you’re thinking about buying one, find out how this HVAC system keeps houses cozy.
How Heat Pumps Run
Heat pumps depend on a refrigeration system like an air conditioner. Most can run similar to a ductless mini-split, since they can heat and cool. Heat pumps rely on an indoor evaporator coil and an outdoor condensing coil. Refrigerant is moved through these coils to shift humidity. The outdoor unit also has a compressor and is surrounded by metal fins that work as a heat sink to help shift heat effectively.
In cooling mode, the refrigerant starts in the evaporator coil. Air from inside the house is distributed over the coil, and the refrigerant removes heat. Water in the air also condenses on the coil, falling into the condensate pan below and drains away. The ensuing dehumidified air flows through the ductwork and back into your home.
Meanwhile, the refrigerant flows a compressor on its way to the outdoor coil. This compresses the refrigerant, leading it to warm up. As it moves through the condensing coil, the exterior fan and metal fins help to discharge heat to the outdoors. The refrigerant moves back indoors, passing through an expansion valve that chills it considerably, prepping it to begin the process from the start.
When your heat pump is put in and maintained appropriately, you’ll have efficient cooling comparable to an energy-saving air conditioner.
When your heat pump is heating, the heat exchange cycle happens in reverse. By moving in the opposing direction, refrigerant extracts heat from the outdoor air and disperses it into your home to warm the inside.
Heat pumps working in heating mode are most efficient when the temperature remains above freezing outside. If it turns too frigid, a backup electric resistance heater turns on to keep your house comfortable, but your heating expenses increase as a result.
Heat pumps operate longer than furnaces since the air doesn’t become as warm. This helps keep a more stable indoor temperature. Also, because heat pumps move warmth rather than generating it from a fuel source, they can perform well above 100% efficiency. You should expect 30–40% savings on your heating expenses by using a heat pump.
