4 Common Signs of a Faulty or Failing AC Sensor

Air conditioning systems have sensors that read the temperature of the air that enters the evaporator coil. They help your equipment reach your desired temperature and effectively cool your living space. When these sensors malfunction, your home’s comfort could suffer.

One of the area’s leading HVAC contractors shares four common signs of a faulty or failing AC sensor.

1. Uneven Cooling

Are you finding it hard to keep your living space comfortable? A malfunctioning AC sensor could be to blame for this issue. Even if you adjust your thermostat multiple times, your home will remain uncomfortably hot or cold if the sensor isn’t working right.

2. Short Cycling

An efficient air conditioning system will automatically turn off after achieving your set temperature. However, your unit will keep cycling on and off if it has a faulty sensor. Hire experienced heating and cooling professionals to address the problem and avoid early system failure.

3. Thermostat Issues

Another reason an AC sensor stops working right is because of a faulty thermostat. Excessive dust or grime buildup and poor installation are typical causes of thermostat failure. The issue can also occur if the device is old and needs replacement.

4. Dislodged Sensor

An AC sensor can malfunction once it moves out of its initial position. As a result, it will not be able to produce accurate temperature readings. When this happens, your AC won’t be able to cool your indoor spaces efficiently.
