Geothermal Heating and Cooling System Troubleshooting for Harried Knox County Homeowners

We’ll lead with the good news: geothermal heating and cooling systems are famous for their trustworthiness, longevity, and ease of maintenance. The bad news? Well, you might not have to face any – if you keep your system well maintained! Nevertheless, even the best of geothermal systems can experience a sporadic hiccup or, yes, even break down once in a blue moon. On those rare occasions, it’s nice to know the Knox County specialists at Cosby Heating and Cooling are here to help.

Prior to calling us, though, you may want to run through the following checklist – just to make sure the problem can’t, in fact, be resolved without us. :-)

Check …

  • The Thermostat’s Seasonal Setting. No heat coming through? No cool air to speak of?  The trouble could be as elementary as having your thermostat set for the wrong season. If that’s the issue, reset it and see if that doesn’t do the trick.
  • The Thermostat’s Temperature Setting. A house that’s already been brought up to 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 restart the heating system in Winter – or five degrees lower to restart the cooling system in Summer.
  • The Fan. A adequately maintained auto setting for the fan assures that it kicks in whenever your geothermal heat pump increases or decreases your home’s temperature. This helps improve the energy efficiency of your system on the whole.
  • The Circuit Breakers and Power Switch. It proves true more often than you’d imagine that the cause of a geothermal system fail 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 the answer’s no, then it’s not at all surprising that you’re not experienceing the warmth or the coolness you seek!
  • The Filters. Here’s where periodic – and simple – self-managed system maintenance definitely proves its merit! 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 handicapped by dust, dirt, and other airborne particulates getting into the heat pump. A sufficient buildup will cut down air circulation, reduce the heating and cooling capability of the system, increase your utility costs, 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, remedied whatever needed remedying, and your geothermal heating and cooling system’s still malfunctioning? Now would be a great time to call us. The experts at Cosby Heating and Cooling have an aptitude for fixing whatever might impair a geothermal system – as scads of harried Knox County homeowners will attest!
