What Is A Heat Pump and How Does a Heat Pump Work?
A heat pump is a dual-purpose HVAC system that heats and cools your home by transferring heat energy rather than generating it from fossil fuels. In the summer, it acts like an air conditioner, removing heat from your home. In the winter, it reverses the process, extracting heat from the outdoor air (even in cold temperatures) and moving it inside. Heat pump systems Electric heat pumps
How Does A Heat Pump Work?
Heat pumps work by using a refrigerant cycle to transfer thermal energy between the indoors and outdoors. They do not burn fuel to create heat; instead, they move existing heat from one place to another, which makes them highly energy-efficient.
“A heat pump uses electricity to provide both heating and cooling to a home,” Mike Lea, co-owner of Lea Heating & Air Conditioning in East Dundee, IL, said. “A heat pump transfers heat from one place to another. In the winter, a heat pump transfers heat from the outdoors and moves it inside. In the summertime, it reverses and it moves the heat from indoors to outdoors. In heating mode, a heat pump works like an air conditioner, but in reverse. Instead of using refrigerant to keep your home cool, it uses refrigerant to warm your home.”
The 3-Step Process of Heat Transfer
- Absorption: The outdoor unit (in air-source systems) extracts heat from the outside air, ground, or water source. Even in cold weather, there is thermal energy present in the air.
- Compression: A compressor increases the pressure and temperature of the refrigerant, concentrating the absorbed heat.
- Distribution: The heated refrigerant flows to the indoor unit, where a fan blows air over the hot coils, releasing warmth into your home. In summer, this flow is simply reversed to pump heat out of the house.
“When I sit at the kitchen table with a homeowner, I like to use the analogy of a refrigerator,” Mark Lea, co-owner of Lea Heating & Air Conditioning in East Dundee, IL, said. “We do not pump cold air into the refrigerator. Inside the refrigerator, what we do is we take and extract all the heat out of the refrigeration to lower the temperature. That's why you have the kick plate at the bottom of the refrigerator blowing warm air out. And every time you open the door and you leave the refrigerator on too long, the compressor comes on.
It’s just the opposite for a heat pump. We take the warm air that we're sitting here in the kitchen and we put it back into the box.”
Types of Heat Pumps
Understanding the different types of heat pumps can help you choose the best option for your climate and property.
Air-Source Heat Pumps
The most common type in North America, air source heat pumps transfer heat between your house and the outside air. They are relatively easy to install and highly efficient, capable of reducing electricity use for heating by approximately 50% compared to electric resistance heating.
Ground-Source (Geothermal Heat Pumps)
Geothermal heat pumps take advantage of the constant temperature of the earth or a nearby water source. By transferring heat to and from the ground, they offer exceptional efficiency and consistent performance regardless of extreme outdoor air temperatures.
Ductless Mini Split Heat Pumps
For homes without existing ductwork, ductless mini split heat pumps offer a flexible solution. They connect an outdoor compressor to individual indoor air-handling units, allowing for zoned temperature control in specific rooms.
4 Key Benefits of Installing a Heat Pump
Why are homeowners increasingly choosing heat pumps over traditional furnaces?
- Energy Efficiency: By transferring heat instead of burning fuel, high efficiency heat pumps can significantly lower your energy bills.
- Versatile Performance: You get a heating system and an air conditioner in one unit, simplifying maintenance and freeing up space.
- Eco-Friendly Operation: Heat pumps reduce your carbon footprint by utilizing electricity (which can come from renewable sources) rather than burning natural gas or oil onsite.
- Cold Climate Reliability: Modern cold climate heat pumps are engineered to perform efficiently in sub-zero temperatures, making them a viable option even in northern regions.

Heat Pump FAQs
A heat pump works like an AC in cooling mode, but unlike a standard AC, it can reverse its operation to also provide heating in cooler months.
A heat pump is a two-in-one system that moves heat in or out of your home—pulling heat inside to warm your house in winter and pushing it out to cool it in summer.
Yes, modern heat pumps—especially cold-climate models—work efficiently in winter, even at freezing or subfreezing temperatures, by extracting heat from the outside air.
Yes, a properly sized heat pump can cool an entire house, delivering even, efficient cooling through ducted or ductless systems. Modern heat pumps are designed to handle whole-home comfort in a wide range of climates.
A heat pump is one part of an HVAC system—it provides both heating and cooling using a single piece of equipment.
Most heat pumps last 10 to 15 years, depending on usage, maintenance, and climate.
