Are You Getting Correct Thermostat Readings? How to Tell.

Do you know how to tell if your thermostat is giving correct readings? Incorrect thermostat readings are a common HVAC problem. This thermostat malfunction can interfere with your HVAC system’s cycling, make your home feel uncomfortably cold or hot, and cause your energy bills to rise. Therefore, testing your thermostat to ensure it’s giving accurate readings is a worthwhile endeavor.

Testing the Accuracy of Your Thermostat Readings

To test your thermostat, you’ll need the following:

• Small thermometer
• Tape
• Paper towel

You’ll need to tape the thermometer to the wall a few feet away from your thermostat, but at the same height and away from windows, doors, direct sunlight, lights, and other heat sources. Set the thermometer on top of the paper towel to prevent cold or heat transfer from the wall from affecting it. Wait for 15 to 20 minutes before checking the temperature on the small thermometer and comparing it to the thermostat reading.

Fixing Incorrect Thermostat Readings

You shouldn’t worry much about a three-degree (or less) difference. If the difference is more than three degrees, a buildup of dirt and debris may be interfering with your thermostat’s ability to read the room temperature accurately.

Use a compressed air can or a soft brush to clean the thermostat casing’s vents. Pop the thermostat cover off and clean the interior gently using a soft brush. Remove corrosion from the metallic contacts using a cotton swab saturated with an electrical contact cleaner. Replace the thermostat batteries if you have a battery-powered unit.

After cleaning, you should leave the thermostat and thermometer in place for another 15 to 20 minutes before rechecking the readings. If the readings are still different, you probably have a problem that requires professional assistance. Some of the possible causes include:

• Wiring issues
• Faulty sensor
• Poor location
• Old age

Getting correct thermostat readings is crucial to your home’s comfort and energy efficiency.
