Does a Geothermal System Need Winter Maintenance?

Geothermal systems can be a bit of a mystery for homeowners who don’t have a lot of HVAC knowledge or experience. This is even true of people who actually have geothermal systems installed in their homes. Not to worry, though, we’re here to answer all of your questions. This week, we’re tackling the subject of winter maintenance with regard to geothermal systems.

Geothermal Maintenance

Geothermal systems do need maintenance at least once or twice a year, just like any other heater. With specific regard to winter maintenance, however, that depends on circumstances. Most other heating systems have their recommended maintenance during the fall season. This is because the best time to conduct maintenance on any system is right before you plan on using it a lot. Maintenance on your heating system right before winter ensures that it will be able to handle the increased strain of frequent use.

In that sense, winter maintenance on your geothermal system is a good idea. You really don’t want your geothermal heater breaking down in the middle of winter. Demand for HVAC repairs tends to rise during the cold season, for obvious reasons. This could lead to a delay of a few days for HVAC service, which means you would be stuck without heat during the coldest months of the year.

As for specific repair needs, geothermal systems are more low-maintenance than most systems. The water in the underground loop can occasionally freeze, but only if the loop isn’t buried far enough down. The actual depth that the loop needs to be buried at depends largely on the region your home is in. In some colder areas of the country, loops can freeze and stop working as deep as 15ft below the surface.

Other than that occasional concern, geothermal systems are much the same as any other heat pump. As long as the reversing valve, refrigerant line, and coils are working, you should have nothing to worry about.
