A heat pump contractor in Palmdale, CA, can explain the difference of air-source and ground-source heat pumps to you. The basic gist is that air-source heat pumps take heat from the air and redistribute it either indoors or outdoors depending on your needs. Ground-source heat pumps rely on geothermal energy. Air-source heat pumps tend to be easier to install and have the capacity to handle almost all residential needs. Ground-source heat pumps, on the other hand, are more expensive and difficult to install; however, they are more efficient and come with lower operation costs.
Proper installation from a licensed heat pump company can make a huge difference in efficiency and lifespan. Many of the newer models have advanced technology that allow them to remain efficient for as long a 20 to 25 years. After that, you’ll need to get a replacement. Newer models also tend to operate quietly and some can even improve indoor air quality. They may even have smart technology integrated into them.
