Geothermal system maintenance tips for homeowners
Air filter. As with most HVAC units, one of the most important
things a homeowner can do to extend the life and maximize the unit’s
efficiency is to regularly clean or change the filters. If done
according to the owner’s manual, this simple geothermal system
preventative maintenance practice can help keep the unit working
effectively by keeping the air coil free of dust and debris.
Condensate drain. Homeowners should also periodically check the
condensate drain. Just as with air conditioning units, condensation
can form on the coils of geothermal systems during the warmer months.
As the condensation flows away, it can take dirt and dust with it,
which, over time, can potentially clog the condensate drain. Check the
drain once per season to make sure water flow isn’t being impeded.
Geothermal system maintenance for dealers
Since geothermal units are closed systems, and contain chemicals
like refrigerants, most maintenance and repairs should be performed by
a certified technician. Here are just a couple of the geothermal
maintenance checks a Trane Comfort Specialist can do during your
yearly HVAC inspection.
Coolant. Geothermal systems work by sending coolant, or a
mixture of water and coolant, through a series of tubes underground,
where they exchange heat to regulate the temperature of your home. And
while these tubes do not usually require maintenance, it is possible
for a leak to form. A Trane Comfort Specialist can test the lines to
make sure no leaks are present, and that the coolant level is correct.
Underground pipes. If the technician does locate a leak, it
will have to be repaired. Leaks in underground geothermal pipes are
rare, but if present, they can significantly impact your system’s
ability to heat and cool your home.
Compared to other HVAC units, geothermal systems are relatively low
maintenance. But damage over time can occur, and geothermal units
should be checked once per year by a Trane Comfort Specialist. Contact
your dealer today to schedule a yearly service check in your home.
