Geothermal Heating and Cooling System Troubleshooting for Harried Wilmington Homeowners

We’ll give you the good news first: geothermal heating and cooling systems are widely recognized for their trustworthiness, longevity, and ease of maintenance. The bad news? Well, you shouldn’t encounter any – if you keep your system adequately maintained! That said, even the finest of geothermal systems can come down with an isolated hiccup or, yes, even break down once in a blue moon. At such times, it’s good to know the Wilmington experts at O'Brien Service Company are here to help.

Prior to calling us, though, you might want to peruse the following checklist – just to confirm that the problem can’t, in fact, be taken care of without us. :-)

Check …

  • The Thermostat’s Seasonal Setting. Can’t get warm? Can’t cool off?  The problem could be as simple as having your thermostat set for the wrong season. If that’s the case, reset it and see if that doesn’t take care of it.
  • The Thermostat’s Temperature Setting. A house that’s already arrived at the warmth or coolness of the thermostat setting won’t prompt your geothermal system’s heat pump to start. Try setting the thermostat five degrees higher to get the heating system restarted in Winter – or five degrees lower to get the cooling system restarted in Summer.
  • The Fan. A sufficiently maintained auto setting for the fan ensures that it operates whenever your geothermal heat pump increases or decreases your home’s temperature. This helps boost the energy efficiency of your system on the whole.
  • The Circuit Breakers and Power Switch. It happens more often than you’d suppose that the cause of a geothermal system malfunction is nothing more than a blown fuse. Or a repercussion of the power switch – indoors or outdoors, in accordance with the kind of system you have – being for whatever reason shut off!
  • The Room Registers. Are your return grilles and supply registers open? If the answer’s no, then it’s perfectly understandable why you’re not experienceing the warmth or the coolness you want!
  • The Filters. Here’s where recurrent – and simple – self-performed system maintenance definitely proves its worth! If you aren’t changing 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 impeded by dust, dirt, and other airborne particulates getting into the heat pump. A sufficient buildup will hinder air circulation, lower the heating and cooling capability of the system, send your utility costs skyrocketing, and cut a few years off your heat pump’s lifetime. Whatever else you do, maintain your air filters!

Okay. So you’ve followed the checklist, righted whatever needed righting, and your geothermal heating and cooling system’s still not functioning properly? Now would be the right time to call us. The pros at O'Brien Service Company have a gift for fixing whatever might incapacitate a geothermal system – as lots of harried Wilmington homeowners will attest!
