Is your HVAC system not functioning as it should in your Keller, TX, home? You may have a problem with your thermostat, which is the communication link to your HVAC unit. Telltale signs such as wrong temperature readings and high utility bills can alert you to the possibility of a faulty thermostat.

HVAC Incorrectly Switches On or Off

Your system may fail to switch on or switch off when it should. For example, it may switch off before your system reaches the programmed temperature, or it may switch on when the room temperature is at the desired or programmed level. All these issues point to the likelihood of a malfunctioning thermostat.

Faulty Readings on the Display

If the room doesn’t feel as cool or warm as the reading displayed on the thermostat, there could be a problem with its temperature sensor. In other cases, information may be missing from the display. The screen may also display different readings than those on the app for your smart home.

Aging Thermostat

The average lifespan of a thermostat is 10 years. After that point, it may begin to malfunction. We recommend that you replace a control that is more than a decade old.

High Utility Bills

If you notice that your energy bills are unusually high for the season, one possible reason is a malfunctioning thermostat. When it incorrectly reads the temperature, it may switch on the HVAC when it shouldn’t, unnecessarily driving up energy use.

Rapid Temperature Fluctuations

If the HVAC is switching on and off rapidly or the room temperature is swinging wildly, the temperature sensor in the thermostat could be sending faulty signals to the HVAC. You may notice that the unit is unable to maintain the set temperature and adjusts it without warning. In such cases, hire a technician to inspect the control for malfunction.

Unresponsive Thermostat

When you change the temperature settings on your thermostat, the response should be almost immediate in the form of the HVAC system switching on or off to conform to the set temperature. If this fails to happen, the control could be malfunctioning.

If you find yourself experiencing any of these telltale signs that your thermostat is malfunctioning, an HVAC technician will need to inspect the unit. Contact us at North Tarrant Heat & Air to schedule a professional inspection, HVAC repair, regular tune-up or maintenance check.
