You might have heard people talk about heat pumps before; however, if you’ve never had one in your home or seen one firsthand, you probably don’t know much about how this solution can transform your home and provide significant long-term savings on your heating and cooling costs.

If you’re interested in adding a heat pump in your home, or you just want to get more information about how a heat pump works, this basic information about these systems can help. We’ll also cover the types of heat pumps you might choose, and how they are installed in your home.

What is a heat pump, and how does a heat pump work?

A heat pump is a two-component system that moves heat from one location to another. This can be used to heat a home or parts of a home by drawing warm air into your living space, but it can also be used to cool a home by pulling warm air out of your home.

This system uses refrigerant and electricity to move warm air, which is similar to the way an air conditioning unit uses refrigerated air to cool your home. The main difference is that air conditioners force cool air into your home, while heat pumps use pressure and heat transfer to move hot air out of the home. This approach is far more efficient, which can result in lower heating and cooling costs overall. In addition, heat pumps can regulate air temperature without the use of ducts, which can be a benefit in homes without existing ductwork.

Different Types of Heat Pumps

Heat pumps come in a few different forms, all of which offer different benefits and potential uses in your home. These categories include:

  • Air-source Heat Pumps: This is the most common type of heat pump used in homes, and transfers air between your home’s interior and the outside air. Air-source pumps can also feature mini-split heat pumps, which are a popular ductless heat pump option in homes.
  • Geothermal Heat Pumps: This includes ground-source and water-source pumps, and transfer heat between your home and nearby ground or water sources. These pumps are typically more expensive to install, but they offer greater heating and cooling savings by taking advantage of nearby heating and cooling sources. These systems are also useful in regions with extreme temperature changes.
  • Absorption Heat Pumps: This is a newer type of heat pump, also known as a gas-fired heat pump. Absorption heat pumps use heat generation to absorb heat from your home’s air.

These basic types of heat pumps can be configured in many different ways to account for the specific heating and challenges for any home, maximizing the potential benefits of installing this system.

Benefits of a Heat Pump System

The greatest benefit of installing a heat pump system in your home has to do with the lifetime savings you will enjoy by reducing your heating and cooling costs. Thanks to the exceptional efficiency of heat pump systems, it’s normal to experience reductions of heating and cooling costs by 50 percent or more. In some cases, a heat pump can fully replace other HVAC appliances.

Heat pump systems can also be set up to use geothermal and/or solar heat, allowing your home to be efficiently heated from a renewable resource. For environmentally-conscious residents, this can make heat pump systems even more appealing beyond their simple financial benefits.

Installing a Heat Pump System

If you’re interested in installing a heat pump system in your home, you will probably want to work with an HVAC company to have this work performed. Installing a brand-new heat pump system requires a lot of work installing ventilation, integrating with existing HVAC equipment, and ensuring that the newly installed system is set up to properly heat and/or cool your home.

In certain climates, a heat pump can be your home’s sole source of heating and cooling, delivering year-round benefits to both your home and your utility bill. But even if you still need other HVAC appliances to supplement your heat pump, this heating-and-cooling solution can still dramatically reduce your monthly utility bills, paying for its own cost of installation over time.
