What is a Heat Pump and How Does it Work?

Published on: December 1, 2019

As homeowners research different heating and cooling systems for their homes, they inevitably come across the term heat pump or HVAC heat pump system. As a resident of Southeastern USA, you may not think that a system like this would be the ideal choice for your needs. These heating and air conditioning units, however, may be the ideal choice for our climate. To fully understand how residential heat pumps can benefit you as a homeowner, you must understand a bit about what they are and how they work.

What are Heat Pumps?

Heat pumps are one of the most popular alternatives to traditional furnaces and air conditioning systems. Simply put, heat pumps move warm air from one location to another. There are three main types of heat pump units; geothermal, water source, and air-to-air, which gather heat from either the soil, water, or air and move the heat in or out of your house.

Air-sourced heat pumps are the most popular for homes and multi-family residences. They are the least expensive. However, homeowners that are looking for a long-term return on their investment should consider a geothermal. It costs less money to run and is more efficient than other units.

How Does a Heat Pump System Work?

When your heat pump is in cooling mode, it absorbs the heat energy from your home and moves it outside. A simplified version of the process goes as follows:

1. Refrigerant is pumped through the indoor coil, which absorbs heat energy from your home. Any leftover air has been cooled, which is pumped back in to the house.

2. This energy turns the refrigerant to gas, which is condensed, and the heat is pumped outside.

3. The refrigerant, once the heat energy has been released, is ready to cycle back through the process.

When set to heating mode, a heat pump will do just the opposite. It will absorb heat energy from the soil, water, or air around your house and transfer that heat energy to your house.
