Does your home feel blazingly hot but your thermostat reads only 74 degrees? Sometimes, your thermostat can say one thing yet the temperature in your house is entirely different. However, before you call an HVAC technician to complain about a broken air conditioning unit, check if the cause of the problem is something you can easily solve.
Here are some of the common causes of a thermostat reading wrong temperature.
Dirty Air Filter
Your air filter can clog up fast if you have shedding pets or a cold air return in a high-traffic room. A clogged filter will hamper your A/C unit's cooling ability. It can also affect whether or not the unit turns on without involving your thermostat. Replace your air filters regularly.
Dirt is also problematic for thermostats. A dirty thermostat will have a difficult time reading the correct temperature inside your home. To clean it, remove the cover and gently dust the inside parts using a soft brush.
Have you set the temperature without checking whether your thermostat is set to cool or heat? With incorrect settings in place, your A/C system won't turn on and function as expected. Verify that your thermostat settings are suitable for the season.
A thermostat does its job quietly, so it's easy for you to set it and forget that its batteries may be dead or dying. Change the batteries and check if normal operation is restored.
Your thermostat will read the wrong temperature if it isn't located in your home's most optimal place. If it's located near drafts or heat sources, or it's in an area that isn't centrally located, you may need to have it moved.
If you can't fix your thermostat problems, contact an HVAC professional soonest possible. A malfunctioning thermostat can lead to inefficient A/C operation and high energy bills.
