In Scottsdale, heat pumps can be a popular option for heating and cooling your house.
They look about the same as an air conditioner. In fact, they run in the same way during high temperatures. Since they have a reversing valve, heat pumps can transfer heat in the opposite direction as well as add warmth to your home in the winter.
Not sure if you use a heat pump or an air conditioner? Simply find the model number on the outdoor unit and check it online. If you already have a heat pump, or if you are considering getting one, here is how these HVAC systems keep your home comfortable:
How Heat Pumps Run
Heat pumps use a refrigeration system similar to an air conditioner. Most can operate similar to a ductless mini-split as they can heat and cool. Heat pumps contain an outdoor condensing coil and an indoor evaporator coil, and move refrigerant through these coils to transfer warmth. The outdoor unit contains a compressor enclosed by metal fins that move warmth by acting as a heat sink.
How Heat Pumps Cool in Summertime
When your heat pump is cooling, the refrigerant starts in the evaporator coil, where it is chilled. Air from within the house is moved over the coil, and the cold refrigerant removes warmth from the air.
Water in the air condenses on the coil, where it drops into the condensate pan below and is drained out of the unit. The ensuing cool air blows through the ductwork and throughout your house.
Next, the refrigerant passes through a compressor on its way to the outdoor coil. The compressor concentrates the refrigerant and causes it to get hotter. As the refrigerant passes through the condensing coil, the exterior fan and metal fins release this heat outside.
The refrigerant heads back into your house, where it passes through an expansion valve that causes its temperature to drop greatly. From there, the process repeats. Once your heat pump is installed and maintained correctly, you will get energy-efficient cooling.
How Heat Pumps Warm in Wintertime
In heating mode, the heat exchange cycle flows in the opposite direction, reversing the process. Refrigerant extracts outdoor heat and disperses it indoors to warm the interior.
Heat pumps operating in heating mode are most effective when outdoor temperatures are above freezing. If it gets too frigid, a backup electric resistance heater should be available to keep your residence comfortable. In southern and central Arizona, heat pumps are often enough to maintain comfortable indoor temperatures during winter months.
Request a Heat Pump Installation or Service Check
Heat pumps are eco-friendly and cost-effective. They are an alternative to the standard AC/heater configuration and require less maintenance than having two separate systems. You will need only one appointment in the spring and another in the fall.
