How do Heat Pumps Work?

September 19, 2022 | Blog

Nothing feels better than a warm house on a cold winter night. For people looking to improve their heating options, it can be very frustrating to learn the ins and outs of installation, purchasing options and regulations depending on your house and where you live. What’s even more mysterious is trying to figure out which type of technology suits your needs the best, and without a professional heater installation, it can be an absolute disaster.

Luckily, Bob’s Heating and Air Conditioning has been faithfully serving families in Berwick, LA for over 25 years, and their explanation of heat pumps can help you understand exactly what is keeping you warm at night.

What is a Heat Pump?

One of the most defining features of a heat pump is that they do not generate heat, rather, they move the heat from one place to another. Heat is instead generated by a furnace, which is why heat pump installation can be quite a daunting task. Making sure that everything is fit accordingly can be detrimental to how effective the heat pump is. For a heat pump to be one of your best heating options, you need to have ample indoor and outdoor space for all of the necessary parts.

How do Heat Pumps Work?

Compared to other heating and air conditioning units, heat pump installation requires very few parts, but a lot of security when putting them together. The normal parts for a heat pump include:

Outdoor and Indoor Units

The outdoor and indoor units are comprised of fans and coils that push outside air to the inside, either condensing the air in a cooling fashion or evaporating the air to create heat. The outdoor unit will cool or heat the air first, pumping it into the indoor unit, which will then regulate the temperature further and push it into the ducts of your house.


Refrigerant is an important part of heat pumps, as this is the part that is able to absorb and reject heat to make for a more efficient transition during temperature changes.

Reversing and Expansion Valves

Reversing and expansion valves should also be considered when evaluating your heating options as they can determine how fast your house can go from hot air to cooler air. Reversing and expansion valves control the air’s relation to heat and the refrigerant, also putting it in different directions throughout your home.
