The best heat pumps are highly efficient heating and cooling systems that provide comfort and climate control in residential and commercial spaces. Understanding how they work is crucial to comprehend the factors that influence the life expectancy of heat pump workability and answering the question of “How Long Do Heat Pumps Last?”. Heat pumps operate on the principle of moving heat from one area to another rather than generating heat through combustion or electrical resistance.

Heat Pump Basic Functionality

Overall, heat pumps offer a sustainable, energy-efficient solution for climate control by leveraging the natural heat exchange processes, providing year-round comfort in homes.

Heat Transfer

Heat pumps use refrigerant to absorb and release heat as it circulates through the system. The refrigerant alternates between a liquid and a gaseous state to absorb and release heat energy.

Evaporation and Condensation

The process starts with the refrigerant absorbing heat from the outdoor air (even in cold temperatures) through an outdoor coil. This causes the refrigerant to evaporate into a low-pressure, cold gas.


The compressor then pressurizes the refrigerant gas, raising its temperature significantly.

Heat Release

The now hot, pressurized gas moves to the indoor coil, where it condenses back into a liquid state, releasing the absorbed heat into the indoor air.


The warm air is then distributed throughout the home using a fan system.

Heat Pump Modes of Operation

During colder weather, the heat pump extracts heat from the outside air and transfers it indoors.

Cooling Mode

In warmer temperatures, the process is reversed. The heat pump removes heat from indoors and releases it outside, cooling the indoor space.

Heat Pump Components

  • Outdoor Unit: Contains the compressor and outdoor coil where heat exchange with the outside air occurs.
  • Indoor Unit: Includes the indoor coil and a fan to distribute conditioned air inside the house.
  • Refrigerant Lines: These lines connect the indoor and outdoor units, transporting the refrigerant between the coils.

Heat Pump Efficiency and Energy Source


Heat pumps are highly efficient as they move heat rather than generate it, making them cost-effective for both heating and cooling.

Energy Source

They can run on electricity and are ideal for moderate climates. However, in extremely cold temperatures, their efficiency might decrease as it becomes more challenging to extract heat from the outdoor air. Proper makes and brands will still be able to reliably heat and cool your home for 15+ years.


Heat pumps’ versatility makes them suitable for regions with mild to moderate climates, where they can efficiently provide both heating and cooling functions, eliminating the need for separate systems.
