In Birmingham, heat pumps can be a popular option for heating and cooling your house.
They appear very similar to an air conditioner. In fact, they run in a nearly identical way during warm weather. Because of a reversing valve, they can transfer warmth in the opposite direction as well as heat your house when temperatures drop.

How Heat Pumps Run
Heat pumps rely on a refrigeration system much like an air conditioner. Most can work like a ductless mini-split, because they can heat and cool. Heat pumps use an indoor evaporator coil and an outdoor condensing coil. Refrigerant is pumped through these coils to move humidity. The outdoor unit also contains a compressor and is surrounded by metal fins that work as a heat sink to help move humidity effectively.
When your heat pump is cooling, the refrigerant is in the evaporator coil. Air from within the house is distributed over the coil, and the refrigerant extracts heat. Water in the air also condenses on the coil, falling into the condensate pan below and drains away. The following cool air circulates through the ductwork and back into your residence.
Meanwhile, the refrigerant flows a compressor on its way to the outdoor coil. This concentrates 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 exterior. The refrigerant moves back into your house, moving through an expansion valve that lowers its temperature it greatly, preparing it to start the process from the beginning.
When your heat pump is installed and maintained appropriately, you’ll receive efficient cooling as good as an energy-saving air conditioner.
In heating mode, the heat exchange procedure occurs in reverse. By flowing in the opposite direction, refrigerant removes heat from the outdoor air and vents it into your home to warm the interior.
Heat pumps working in heating mode are most useful when the temperature is warmer than freezing outside. If it gets too frigid, a backup electric resistance heater turns on to keep your home cozy, but your heating costs rise as a result.
Heat pumps work longer than furnaces as the air doesn’t become as hot. This helps sustain a more even indoor temperature. Also, because heat pumps shift heat rather than creating 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.
