Geothermal Heating and Cooling System Troubleshooting for Harried San Antonio Homeowners

Here’s the good news: geothermal heating and cooling systems are famous for their trustworthiness, longevity, and ease of maintenance. The bad news? Well, there shouldn’t be any – if you keep your system well maintained! Nevertheless, even the finest of geothermal systems can develop an isolated hiccup or, yes, even break down once in a blue moon. At such times, it’s nice to know the San Antonio specialists at Southwest Mechanical Services are here to help.

Before you call us, though, you might want to look over the following checklist – just to make sure the problem can’t, in fact, be corrected without us. :-)

Check …

  • The Thermostat’s Seasonal Setting. Can’t get warm? Can’t cool off?  The difficulty could be as elementary as having your thermostat set for the wrong season. If that’s the situation, reset it and see if that doesn’t improve matters.
  • The Thermostat’s Temperature Setting. A house that’s already reached the warmth or coolness of the thermostat setting won’t set off 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 makes certain that it runs 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 frequently than you’d figure that the cause of a geothermal system malfunction is nothing more than a blown fuse. Or the result of the power switch – indoors or outdoors, regarding the sort of system you have – being somehow shut off!
  • The Room Registers. Are your return grilles and supply registers open? If they’re closed, well, then no wonder you’re not experienceing the warmth or the coolness you want!
  • The Filters. Here’s where a program of methodical – and simple – self-performed system maintenance unquestionably proves its worth! If you aren’t replacing 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 crippled by dust, dirt, and other airborne particulates working their way into the heat pump. A sufficient buildup will hinder air circulation, lower the heating and cooling capability of the system, raise your utility costs, and take a few years off your heat pump’s lifetime. Whatever else you do, maintain your air filters!

Okay. So you’ve run through the checklist, righted whatever needed righting, and your geothermal heating and cooling system’s still not running properly? Now would be a swell time to call us. The specialists at Southwest Mechanical Services have a talent for fixing whatever might disable a geothermal system – as plenty of harried San Antonio homeowners will verify!
