Why Geothermal Heat Pumps Have Filters Some heat pumps don't come with a filter. A good way to figure out if your heat pump has a filter is whether there is ductwork in the house. If this is the case, you have a water-to-air heat pump. This filter cleans the air entering into the heat pump, removing pet hair, dander and other air-borne particles. This keeps the heat pump clean and re-circulates clean air throughout your home.

Why Change Your furnace Filter? With time your heat pump's filter will get dirty with dust and debris. A dirty geothermal filter will reduce air flow to the heat pump, reducing overall performance. If unchecked, over time, it could harm your heat pump's compressor too. When this happens it usually comes with an expensive service bill. So remember to check the filter at least two times a year, and change it when it needs changing. We carry a large supply of Geothermal Furnace Filters, including typical sizes 30x32x2 and 30x36x2 .  Please contact us if you require a special size that you are having difficulty finding.
