How Do I Know If My Thermostat Is Causing HVAC Problems?
When your HVAC system isn’t heating or cooling properly, your first instinct might be to blame the furnace or AC unit—but sometimes, the thermostat is the real culprit. At Integrity Air Solutions, we often find that a small thermostat issue can cause big system problems. So how do you know if your thermostat is to blame?
Common Signs of a Faulty Thermostat
Inconsistent Temperatures:
If some rooms feel warmer or cooler than others, or if the HVAC system doesn't match your thermostat setting, your thermostat might be misreading the temperature or sending incorrect signals.
System Won’t Turn On or Off:
If your heating or cooling won’t start or won’t stop running, a malfunctioning thermostat may not be communicating correctly with your HVAC system.
Unresponsive Controls:
If pressing buttons on your thermostat does nothing, or if the screen is blank or flickering, there may be an internal wiring issue or dead batteries that need attention.
Frequent Cycling:
Short cycling—when your system turns on and off rapidly—can be caused by a thermostat that's placed in a poor location or is malfunctioning.
Thermostat Settings Don’t Hold:
If your programmed schedules keep resetting or disappearing, especially on smart or programmable thermostats, it could mean a software glitch or internal failure.
