Why Isn’t My Geothermal HVAC System in Henrico, VA, Working?

Geothermal HVAC systems are effective because they operate by tapping into the heat stored underground. This method comes with many benefits such as durability and high performance. However, despite proper care and maintenance services, your geothermal HVAC system in Henrico, VA, may stop working efficiently. Read on to learn why.

Incorrect Thermostat Settings

The first thing you should always check is the thermostat. Ensure you have correctly set it at the right temperature and that’s not too low or too high. It’s best to put it on “auto,” which regulates the fan blower when the heat pump is running.

Next, you need to ensure that the temperature settings are higher during winter and lower in the summer. It’s best when you set the temperatures five degrees lower or higher, depending on whether you want to cool or warm up your home.

Clogged Air Filter

Faulty air filters in your geothermal HVAC system will prevent air from circulating smoothly. Dirt buildup may be what’s clogging your air filters.

You may need to clean or replace your air filters. You can do this once every three months. You can also call our service technicians for a maintenance check, and they’ll clean and replace your air filter as well as any faulty parts.


A leaking pipe in your heating pump will lead to the system not working efficiently. Our technicians will determine where the leaks originate from and they’ll seal them well.

Closed Registers

You might notice there’s less cool air in the room, but it could be that you have closed the room grilles or you have blocked them with furniture or curtains. Take a walk through your rooms and ensure the registers are open.

There are many other reasons your geothermal HVAC system might not be working, such as corroded heating coils or a faulty pump. Schedule an appointment for heat pump repair by contacting Atlantic Shores Heating and Cooling. We’ll perform a complete service check and repair of your HVAC system.
