Geothermal Heating and Cooling System Troubleshooting for Harried Homeowners

The good news is, geothermal heating and cooling systems are acclaimed for their trustworthiness, longevity, and ease of maintenance. The bad news? Well, you shouldn’t encounter any – if you keep your system well maintained! Still, even the greatest of geothermal systems can fall victim to an occasional hiccup or, yes, even break down once in a blue moon. At such times, it’s encouraging to know the pros at Ground Loop Heating & Air Conditioning, Inc are here to help.

Before you call us, though, you probably ought to cast an eye on the following checklist – just to ensure that the problem can’t, in fact, be solved without us. :-)

Check …

  • The Thermostat’s Seasonal Setting. Can’t get warm? Can’t cool off?  The difficulty could be as straightforward as having your thermostat set for the wrong season. If so, reset it and see if that doesn’t straighten things out.
  • The Thermostat’s Temperature Setting. A house that’s already reached the warmth or coolness of the thermostat setting won’t start up your geothermal system’s heat pump. Try setting the thermostat five degrees higher to restart the heating system in Winter – or five degrees lower to restart the cooling system in Summer.
  • The Fan. A well maintained auto setting for the fan insures that it operates whenever your geothermal heat pump cranks up or drops your home’s temperature. This helps boost the energy efficiency of your system generally.
  • The Circuit Breakers and Power Switch. It turns out more often than you’d suppose that the cause of a geothermal system failure is nothing more than a blown fuse. Or the result of the power switch – indoors or outdoors, dependent upon the type of system you have – being somehow shut off!
  • The Room Registers. Are your return grilles and supply registers open? If not, then it stands to reason you’re not getting the warmth or the coolness you seek!
  • The Filters. Here’s where regular – and simple – DIY system maintenance truly proves its value! If you aren’t swapping out disposable air filters every three months, or vacuum-cleaning permanent filters every one to three months, your geothermal heating and cooling system may well be hobbled by dust, dirt, and other airborne particulates invading the heat pump. A sufficient buildup will restrict air circulation, reduce the heating and cooling capability of the system, send your utility costs soaring, and cut a few years off your heat pump’s lifetime. By all means, maintain your air filters!

Okay. So you’ve gone through the checklist, corrected whatever needed correcting, and your geothermal heating and cooling system’s still out of whack? Now would be a great time to call us. The experts at Ground Loop Heating & Air Conditioning, Inc have an aptitude for fixing whatever might incapacitate a geothermal system – as plenty of harried homeowners will attest!
