Tempe AC Repair. Common Causes For Thermostat Issues

Phoenix AC Repair. Common Causes For Thermostat Issues

Are you having HVAC problems? Before calling a Tempe AC repair specialist, try these thermostat troubleshooting tips.

They’ve come a long way from the original dial, and you can save hundreds of dollars on power bills by the thermostat remembering your home’s temperature needs. Your HVAC unit only runs when needed, and you’ll always be in a comfortable home.

With such advances, programmable gadgets have become more challenging to use for some. For example, incorrectly, programming a thermostat can lead to poor HVAC performance and system failure.

Regardless of your model’s design, a faulty thermostat could be the culprit behind your HVAC problems.

Here are some tips from local Tempe AC repair experts, and if you can’t fix them, you know who to call.



Heating and Cooling Problems With Faulty Thermostats

Try these tips if you have frequent heating or cooling problems:

 The widespread circular or rectangular “mercury” thermostat design can be sensitive. Dust can impact their efficiency. Therefore, a light dusting of the exterior and interior of an older thermostat may be required.

Your thermostat’s age, so will the “newer” digital models. If your thermostat is 15 years old or older, the wiring may be the culprit—replacement with an energy-efficient model.


Energy-Efficient Thermostats 

  • Is it cooling or heating? Make sure it’s programmed in the proper mode.
  • Turn the thermostat off and on again to reset the system.
  • Check the fan mode isn’t activated by accident.
  • Check the settings. If they are set right, conduct a heating or cooling test by setting the temperature a few degrees on either side of the setting.
  • If your thermostat needs batteries, sometimes all it takes is a new set.
  • Check the circuit breaker to make sure there is no power to issue.
  • Check the wiring on the back to make sure it’s working correctly.
  • Your thermostat’s anticipator may need adjusting. Look for a bit of metal tab close to a scale on your thermostat’s housing. Try adjusting the anticipator’s “longer,” setting one calibration mark at a time.


AC Cycles On and Off

If your HVAC system is cycling on and off too frequently, it may be a thermostat issue. Also, debris and filth in your HVAC components can cause rapid cycling, another reason for periodic maintenance. If your system is cycling too often, consider these:

If you have a mechanical thermostat, remove the lid and level the subbase. A twisted mercury switch inside won’t work correctly.

Besides this, a thermostat that ghost reads or read from a nearby temperature can cause problems. A window or door can be an issue, so place your thermostat away from appliances and hot zones. A proper air sample should be five feet off the floor.
