What Is A Heat Pump and How Does a Heat Pump Work?
By Travis Baugh | Expert Review By Michelle Notaro - Product Manager, Heat Pumps
A heat pump is an HVAC system that heats and cools your home by transferring heat energy rather than burning fuel to create it. A heat pump can act like an air conditioner in summer, removing heat from your home, and reverse the process in winter to transfer heat from the outdoor air into your home. Because heat pumps transfer existing thermal energy rather than generate heat through combustion, they can provide efficient heating and cooling from one system.
How Does A Heat Pump Work?
Heat pump systems use a continuous refrigeration cycle to transfer thermal energy between the indoors and outdoors. Bryant heat pumps use this process to provide both heating and cooling from the same system.
“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.”
What Is the 3-Step Process of Heat Transfer?
Bryant heat pumps use a refrigerant cycle that can be simplified into three key stages: heat absorption, compression and heat distribution. The exact components and controls vary by system.
- Heat Absorption: The outdoor unit in an air-source heat pump absorbs thermal energy from the outdoor air through the refrigerant cycle. Even when outdoor temperatures are below freezing, outdoor air still contains thermal energy that a heat pump can extract.
- Compression: The compressor raises the refrigerant's pressure and temperature, preparing it to release the transferred heat.
- Heat Distribution: The refrigerant carries the transferred heat to the indoor coil, where the heat is released into the home. In cooling mode, the refrigeration cycle reverses and moves heat from indoors to outdoors.
Mark Lea, co-owner of Lea Heating & Air Conditioning in East Dundee, IL, uses a relatable analogy to explain the process.
“When I sit at the kitchen table with a homeowner, I like to use the analogy of a refrigerator,” Lea 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.”
What Are the Types of Heat Pumps?
Heat pumps can be classified by the source they use to exchange heat, including air-source and ground-source (geothermal) systems. Ductless mini-split heat pumps are a type of air-source heat pump that uses an outdoor unit connected to one or more indoor units. Understanding their differences can help you choose the best heat pump for your climate, budget, and property.
Air-Source Heat Pumps
Air-source heat pumps are the most common type in North America. Air source heat pumps transfer heat between your home and the outside air. Modern air source heat pumps can provide efficient heating and cooling across a wide range of climates, while cold climate heat pumps are specifically tested for low-temperature performance. ENERGY STAR® cold-climate requirements include performance testing at 5°F.
Ground-Source (Geothermal Heat Pumps)
Geothermal heat pumps take advantage of the relatively stable temperature of the earth or a nearby water source. By transferring heat to and from the ground, geothermal systems can provide consistent heating and cooling performance without relying on outdoor air as the heat source or heat sink.
Ductless Mini Split Heat Pumps
For homes without existing ductwork, ductless mini split heat pumps offer a flexible solution. Mini-splits connect an outdoor compressor to individual indoor air-handling units, allowing for zoned temperature control in specific rooms. They can be useful in additions, older homes, or spaces where installing traditional ductwork is impractical or costly.

What Are the Key Benefits of Installing a Heat Pump?
Homeowners are increasingly considering heat pumps because they can provide heating and cooling from one system, efficient electric operation, and cold-weather performance when properly selected for the climate.
- Energy Efficiency: By transferring heat instead of burning fuel, high efficiency heat pumps can significantly lower your energy bills.
- Versatile Performance: A heat pump can provide both heating and cooling in one system, reducing the need for separate heating and cooling equipment.
- Electric Operation: Heat pumps use electricity to transfer heat. When electricity comes from renewable sources, the home's heating and cooling can be powered in part or entirely by renewable energy.
- 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.

Do Heat Pumps Work in Cold Climates?
Yes. Modern heat pumps, particularly cold-climate models, are designed to provide heating at low outdoor temperatures. ENERGY STAR® evaluates cold-climate heat pumps at 5°F, and qualifying systems must meet specific heating-capacity and efficiency requirements at that temperature.
Bryant offers models designed for cold-weather operation. For example, the Bryant 291VAN is designed to maintain 100% heating capacity down to 0°F, while the 290VAN is rated for heating operation down to -11°F.
Actual performance at very low temperatures varies by model, equipment combination, installation and operating conditions.

Heat Pump vs. Air Conditioner
While both heat pumps and central air conditioners cool your home using the same refrigeration process, the biggest difference is that a heat pump can both cool and heat, while a standard air conditioner only provides cooling and requires a separate furnace or other heating system for winter.
In terms of cost, heat pumps typically have a higher upfront installation cost than a central air conditioner because they perform two functions in one system. However, they can also reduce annual energy costs in many climates by using electricity to move heat rather than generate it. In moderate climates, a heat pump may provide lower heating costs than electric resistance heat or propane, while homeowners in colder regions often pair a heat pump with a gas furnace for maximum comfort and efficiency.
For homeowners who already have an efficient gas furnace, replacing only the air conditioner may be the most cost-effective option. If you're installing a new HVAC system or want an all-electric heating and cooling solution, a heat pump may offer greater year-round efficiency and long-term energy savings. The best choice depends on your local climate, energy costs, existing equipment, and comfort goals.
