3 Symptoms of a Bad AC Sensor in Sterling, VA
The average AC in Sterling, VA, contains multiple sensors that help it function. When any of those sensors go bad, it can lead to some unusual symptoms. Here are three symptoms that can alert you to a bad AC sensor.
1. Unusual Energy Bill Spikes
An unusual energy bill spike is one sign of a sensor problem in your air conditioner. Your AC relies on sensors to tell it when and how to operate. A failing sensor could send bogus information that causes the AC to run longer than necessary.
Unfortunately, this nonspecific symptom doesn’t point toward one particular sensor or another. So, you’ll need one of our expert HVAC technicians to investigate and solve the problem.
2. Erratic Cycles
Another sign of AC sensor problems is erratic cycling. In mild weather, your AC might run for 15 minutes three times each hour. In hotter weather, it may run for longer during each cycle.
If your AC turns on or off rapidly or runs at seemingly random intervals, it may have this problem. That will lead to unstable indoor temperatures and increase wear and tear on your AC. As a result, promptly investigating and solving the cause of erratic AC cycling is critical.
3. AC Won’t Turn Off at Set Temperature
Finally, if your AC stops turning off when your home reaches your set temperature, a failed sensor may be why. It can happen when one of your AC’s internal parts reports a temperature that conflicts with your thermostat. Since your centrally located thermostat only represents your home’s mean temperature, your AC might ignore it and keep running.
This symptom usually occurs when the temperature sensor near your AC’s evaporator coil fails. If the failed sensor reports an abnormally high incoming air temperature, your AC will work overtime to compensate. Since the failed sensor will never update its reading, your AC can’t shut down.
