The Difference Between Heat Pumps and Traditional ACs

Both heat pumps and air conditioners cool your home using the second law of thermodynamics (heat will always flow from a warmer area to a cooler area). Air conditioners work by absorbing heat from the inside of a room and releasing it outside. To do this, they use a refrigerant fluid that cycles through a system of coils, compressors, and expansion valves. During this cycle, the refrigerant is compressed by a compressor, raising its temperature and pressure. It then flows through the condenser coils where it releases heat to the outside. After releasing its heat, the refrigerant expands and cools significantly in the evaporator coils. As it passes through these coils, it absorbs heat from the indoor air, cooling the environment. This process not only cools the air but also removes humidity, making the indoor environment more comfortable.

Heat pumps, during a cooling season, function the same exact way air conditioners do, moving heat from inside a home to outside. During the heating season, heat pumps reverse the process to heat a home. The same refrigeration loop used to cool the home is reversed to extract heat from the outside air — even in cold temperatures — and bring it indoors.

Heat pumps offer increased efficiency, which makes them a more appealing choice for energy-conscious homeowners in areas like St. Louis, with our hot summers and cold winters. Additionally, since heat pumps can be used year-round, they offer a practical solution for maintaining comfortable indoor temperatures in varying seasonal conditions without the need for separate systems.

How Are Heat Pumps Better Than Air Conditioners?

Heat pumps offer several compelling advantages over traditional air conditioners:

Energy Efficiency

Heat pumps transfer heat rather than generate it by combustion, making them significantly more energy efficient. In climates like St. Louis’s, where temperatures fluctuate across seasons, heat pumps maintain an optimal balance by using less electricity to produce the same amount of heating or cooling as traditional HVAC systems. This efficiency significantly reduces your monthly energy bills throughout the lifetime of the system, saving you as much as $300-$1,500 a year.


Most heat pumps – especially the most energy efficient heat pumps – will have a higher initial cost than most traditional ACs. However, the upfront cost is offset by a few different factors:

Versatility & Comfort

One of the most significant advantages of heat pumps is their dual functionality. Heat pumps can cool your home during the summer and provide warmth in the winter. This versatility ensures homeowners can enjoy comfortable indoor temperatures year-round without the need for separate systems. That means you only pay for one system to be installed, repaired, and maintained.

Reduce Your Carbon Footprint

By utilizing electricity instead of combustion for heat, thus minimizing the burning of fuels, heat pumps have a much smaller carbon footprint than conventional heating systems. This reduced environmental impact aligns well with many St. Louis homeowners’ increasing emphasis on sustainability, energy conservation, and being environmentally friendly.
