A geothermal heat pump can heat and cool your Alexandria, Virginia, home by using the constant temperatures underground. It works like a conventional heat pump, but it uses water or refrigerant instead of air to transfer heat. This makes it more efficient. A geothermal heat pump can last for up to 50 years, but it needs regular maintenance just like other HVAC systems. You should take care of your ductwork, change your air filter often, and have your geothermal heat pump inspected by a professional once per year.

Check Your Ductwork

In spring and fall, check any exposed air ducts in your basement or attic for damage or leaks. Look for ducts that aren’t connected well and holes in ductwork or insulation. Leaky ducts increase your utility bills and lower your comfort. You can seal small leaks yourself, but ducts with lots of leaks in exposed areas probably have other troubles in places only a professional can access.

Every few years and when you have trouble with asthma or allergies, remove one of your air registers, and look at the inside of the duct. If it’s dirty or moldy, having it cleaned by a professional can improve your indoor air quality.

Change Your Air Filter

Like other systems, geothermal units have air filters that need regular changing to keep dust and debris away from coils and other components. Check your filter once per month and change it as soon as it gets dirty.

Have a Professional Inspect Your System

A professional HVAC technician should inspect your geothermal heat pump every year to lubricate motor, bearings, and other parts if needed; make sure your thermostat is working correctly, and clean all parts including the coils. You should also have your condensate drain line, wiring, and refrigerant level checked. Low refrigerant could be a sign of a leak in one of your underground pipes.
