Your thermostat is registering a comfortable 73 degrees, but it feels so hot inside your home that you’ve started to sweat. Is there an issue with your thermostat? Is your air conditioning system acting up? Here are five things to inspect when your thermostat is registering an incorrect temperature.

1. Batteries

Older thermostats that rely upon mechanical switches are often powered by batteries. Those batteries need to be replaced periodically for the thermostat to operate optimally. Alkaline batteries deplete fairly quickly. For optimal thermostat performance, try to use lithium AA batteries.

2. Gradient

Some older thermostats use mercury switches to communicate with your HVAC system. These thermostats are particularly sensitive to direction gradients. They must be kept absolutely level in order to function the way they were engineered to operate.

3. Placement

Thermostat placement is important, too. If your thermostat is in an area of your home that receives ambient drafts, it may register a temperature that is falsely low.

4. Broken Sensors

The sensor inside your thermostat could be malfunctioning. This means that the information it’s providing to other parts of your HVAC system is false. Try cleaning the thermostat and recalibrating it. If this doesn’t work, you may need to think about replacing the sensor.

5. Mismatched Components

If your thermostat is not matched precisely to the capacity of your air conditioning equipment, it could be giving you false readings. It’s important to consult with an experienced HVAC professional whenever you’re replacing HVAC equipment to make sure your new components are compatible.
