Heat pumps are a great way to keep your home warm in the winter and cool in the summer. Knowing how they work can make a big difference in whether you want one for your home. So, how does a heat pump work in the winter? Keep reading to find out.

How Heat Pumps Work

Heat pumps work in the summer to take the warm air from inside your house and pump it outside so that your home will be cooler. The fans take the air from inside the home and then push it through the system, where it is cooled down and then pumped back into the house as cold air. This is a circular system and the heat from inside your home is going to be absorbed and then released outside.

Having your heat pump serviced regularly is going to help you make sure that it is going to keep working all winter. It can be hard to ensure that it is working properly, but your heat pump can work well all winter with the right service program and the right services.

Heat Pumps in Low Temperatures

In colder weather, heat pumps work in a similar manner to how they function in the summer, just with a little different flow of air. The heat pump does not create heat like some units do or like space heaters do. Instead, the heat pump will absorb the heat from the air outside and then pump it back into the house. They work to transfer the heat that is already present and then redistribute it.

When the temperatures are above 40 degrees, it is not a huge struggle for the heat pump. When the temperature drops below 40 degrees Fahrenheit, the heat pump will start to struggle, and that is when something called resistance heat starts to work. This uses heating coils installed in the HVAC system to help heat the air being pumped into the home.

This may also be called AUX heat or emergency heat on your system, and you may not ever need to use it. In cases where it is very cold, the emergency heat will kick on automatically in some cases. If it does not, you may need to start the emergency heat on your own to help keep the home warm. As long as your heat pump has been serviced properly and is in good shape, you should not have any issues or problems with the heat pump.
