How Does a Heat Pump Work?

A heat pump works like a traditional central air conditioning system in the summer.

The coil in the indoor unit acts as the evaporator. As air from inside your home blows over the coil, the refrigerant absorbs heat from the air, and it transforms from liquid to gas. This generates cool air that is blown through your ductwork.

The gaseous refrigerant is then compressed and sent to the coil in the outdoor unit, which is serving as the condenser. The refrigerant transfers the heat to the outdoor air so it turns back to its liquid form and starts the cycle again.

In the winter, the cycle reverses to heat your home. A reversal valve swaps the roles of the condenser and evaporator coils, absorbing heat from the outdoor air and bringing it inside.

A heat pump offers energy-efficient heating and cooling, so you don’t need an air conditioner and furnace.

Frequently Asked Questions

Do I need a furnace with a heat pump?

In extremely cold weather, heat pumps can become less efficient at heating your home. If you want a backup option, a dual-fuel system may be a better fit.

This type of system uses a highly efficient heat pump to heat and cool most of the time and a furnace to provide stronger heat in freezing temperatures.

What happens if your heat pump’s reversing valve is stuck?

When your reversing valve is stuck, your heat pump will remain in the last mode previously used, whether that was heating or cooling.

Although tapping the reversing valve may help it switch properly again, it will need to be professionally replaced in most cases.

When should I schedule heat pump maintenance?

Ideally, you should schedule maintenance visits in the spring and fall to ensure your system is working correctly and ready to keep your home comfortable through peak heating and cooling seasons.

As long as you schedule maintenance twice a year, you’re keeping your heat pump in good condition.
