How a Heat Pump Cools Your House

In Hillsborough, heat pumps can be a popular option for heating and cooling your home.

They appear almost like an air conditioner. In actuality, they run in a nearly identical way during warm weather. Due to a reversing valve, they can move warmth in the opposite direction as well as heat your house in the winter.

Not sure if you rely on a heat pump or an air conditioner? All you have to do is track down the model number on the outdoor unit and run it online. If you discover you use a heat pump, or you’re thinking over purchasing one, find out how this HVAC unit keeps houses comfy.

How Heat Pumps Operate

Heat pumps rely on a refrigeration system much like an air conditioner. Most can run akin to a ductless mini-split, since they can heat and cool. Heat pumps depend on an indoor evaporator coil and an outdoor condensing coil. Refrigerant is pumped through these coils to move heat. The outdoor unit also contains a compressor and is enclosed by metal fins that work as a heat sink to help shift humidity efficiently.

Summertime Cooling

In cooling mode, the refrigerant starts in the evaporator coil. Air from within the house is set over the coil, and the refrigerant extracts heat. Wetness in the air also condenses on the coil, falling into the condensate pan below and flows away. The ensuing dehumidified air flows through the ductwork and back into your house.

At the same time, the refrigerant passes through a compressor on its way to the outdoor coil. This concentrates the refrigerant, leading it to warm up. As it goes through the condensing coil, the outside fan and metal fins help to discharge heat to the outside. The refrigerant travels back indoors, passing through an expansion valve that chills it significantly, readying it to start the process from the beginning.

When your heat pump is replaced and maintained properly, you’ll have efficient cooling comparable to an energy-saving air conditioner.

Wintertime Heating

In heating mode, the heat exchange procedure occurs the opposite way. By flowing in the opposite direction, refrigerant extracts heat from the outdoor air and adds it into your house to warm rooms.

Heat pumps working in heating mode are most efficient when the temperature remains above freezing outside. If it becomes too cold, a backup electric resistance heater kicks on to keep your home comfortable, but your heating bills increase as a result.

Heat pumps work longer than furnaces because the air doesn’t become as warm. This helps maintain a more stable indoor temperature. Additionally, because heat pumps transfer heat rather than making it from a fuel source, they can perform well above 100% efficiency. You can anticipate 30–40% savings on your heating costs by using a heat pump.
