Environmentally conscious homeowners in Annapolis, Maryland, understand the benefits of a geothermal HVAC system. That’s why many choose to have it installed in a new building or an older home when replacing an outdated unit. Geothermal systems can help you save a significant amount of money. Once you own a geothermal HVAC system, you need to know the signs that indicate it requires a rare repair.

Higher Energy Bills

A geothermal HVAC system is highly efficient and uses very little energy. An increased electricity bill could indicate your unit isn’t functioning properly and is utilizing more energy. The heat pump is usually the cause of these problems, and this repair costs less than replacing the system.

Loss of Power

If your system isn’t getting enough power, your home may not be as hot or cool as you need it. This might be as simple as a dirty filter. You can check the filter and change if necessary. But if the unit continues with a loss of power, call our certified service technicians for an assessment.

Rattling Noises

It’s always possible that parts on the heat pump unit will wear out. If you hear a rattling noise, this could be a problem with the fan motor. Mechanical issues will affect the unit’s efficiency, and you should address them right away to avoid larger problems. These issues are usually a simple fix. Our service technicians can get your unit back up and running correctly in no time.

Wet Spots in the Lawn

As your HVAC system ages, you may notice wet patches on the lawn where the loops may be leaking. Depending on the type of loop system you’re using, we may be able to repair the loop and fix the problem. Allow one of our certified service technicians to assess and diagnose the issue. We can insert a dye into the system and determine the leak’s location and whether it requires repair or a replacement.

Corrosion

Another problem you might encounter as the system ages is corroded coils. When this happens, the coils restrict the exchange of heat from the ground and corrosion isn’t easy to remove. If you know your geothermal unit is 20 years old or older, it probably needs replacing. The newer geothermal systems also use a more environmentally friendly refrigerant. As a result, you can become an even greener homeowner.

Malfunctioning Coils

If you notice ice developing on the coils of your HVAC unit, there’s probably a refrigerant leak and the coils are no longer absorbing heat. You might also notice a chemical or burning smell when using either heating or cooling. This needs to be quickly addressed, and it’s best to turn off the unit until a service technician arrives. We can come out, check the unit, and let you know if you need to repair or replace it.

The best way to take care of your geothermal HVAC system is to let a professional perform regular maintenance. Since these units are a big investment in your home, you should sign up for our preventative maintenance plan to ensure the unit lasts for a long time.
