Geothermal Heating and Cooling System Troubleshooting for Harried Seattle Homeowners

We’ll open with the good news: geothermal heating and cooling systems are famous for their reliability, longevity, and ease of maintenance. The bad news? Well, you might not have to face any – if you keep your system well maintained! That said, even the greatest of geothermal systems can experience an occasional hiccup or, yes, even break down once in a blue moon. In those instances, it’s nice to know the Seattle specialists at Vaughn Mechanical are here to help.

Prior to calling us, though, you probably ought to look over the following checklist – just to make sure the problem can’t, in fact, be taken care of without us. :-)

Check …

  • The Thermostat’s Seasonal Setting. No heat coming through? No cool air to speak of?  The difficulty could be as simple as having your thermostat set for the wrong season. If so, reset it and see if that doesn’t put things right.
  • 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 get the heating system restarted in Winter – or five degrees lower to get the cooling system restarted in Summer.
  • The Fan. A well maintained auto setting for the fan makes certain 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 generally.
  • The Circuit Breakers and Power Switch. It happens more frequently than you’d imagine that the cause of a geothermal system malfunction is nothing more than a blown fuse. Or a consequence of the power switch – indoors or outdoors, depending on 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 want!
  • The Filters. Here’s where regular – and simple – do-it-yourself system maintenance undeniably 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 getting into the heat pump. A sufficient buildup will hinder air circulation, lessen the heating and cooling capability of the system, increase your utility costs, and trim 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, rectified whatever needed rectifying, and your geothermal heating and cooling system’s still not running properly? Now would be a swell time to call us. The pros at Vaughn Mechanical have a knack for fixing whatever might impair a geothermal system – as lots of harried Seattle homeowners will attest!
