Usually, there are specific signs indicating that your thermostat might have a calibration problem. Let’s look at the two most common signs.
When you are suspecting that your thermostat is not calibrated correctly, you can follow the following steps to determine whether you have a calibration problem. 1. Step 1: Get a thermometer, and after you’ve wrapped it in a paper towel, place it somewhere close to your thermostat. If needed, you can tape the thermometer to the wall next to the the...
1. Mechanical and programmable thermostats
Because your thermostat may lose calibration due to dust inside the thermostat, a good cleaning could solve the problem. If you have a mechanical or programmable thermostat, put off the power to the thermostat because you have to remove the front cover of the thermostat. The best is to put it off at the circuit breaker. Remove the front cover of your programmable or mechanical thermostat. Take a soft brush and clean the dust inside the thermostat. Use Q-tips or a soft cloth for cleaning. Whil...
2. Smart thermostats
Smart thermostats don’t need internal cleaning. Just use a soft cloth to lightly dust off the screen and the area around the thermostat. When you’re satisfied that all “outside” dust is removed, do the thermometer-thermostat test again. If the difference between the two readings is still more than 3 degrees, you’ll have to calibrate your smart thermostat.
1. Programmable and smart thermostats
Always remember that although I provide you with steps that will, in most instances, apply to your thermostat, every thermostat model has different controls. Thus, use the “logical” steps I’m providing and find the exact procedure for your thermostat in its manual.
2. Mechanical Thermostat
If you’re using a mechanical thermostat, you can also calibrate it if it is giving you incorrect readings according to the thermometer-thermostat test. But you must remember that there are two types of mechanical thermostats. One type is equipped with a calibration screw, and the other type has a mercury switch. Because each type has a different process to follow to calibrate it, you have to know which type of thermostat you have. You’ll find the detail either in the owner’s manual or online.
Final resort if you don’t get the calibration issue fixed
If you couldn’t fix your thermostat’s calibration problem, the best is to contact your HVAC technician for help. The technician will be able to determine whether it is a thermostat problem or whether there are other reasons for the uncomfortable temperature in your home.
For your convenience and to prevent you from spending time calibrating your thermostat while calibration is not the problem, I’ll briefly mention other possible causes of temperature issues in your home. 1. The thermostat batteries might be low or bad and this can be rectified by replacing the batteries with fresh batteries into the thermostat. 2. ...
Q1: Is it always a thermostat-related issue if the temperature in my house is fluctuating? A:Sometimes the problem is not thermostat-related. The problem might be with the HVAC system itself. Poor air circulation, frozen AC coils, and dirty sensors can all cause an HVAC system to run improperly. Q2: What are the two main reasons why a thermostat lo...

Fortunately, it is relatively easy to recalibrate the thermostat again and enable it to control the HVAC system effectively. It is, in any case, a good habit to check your thermostat’s calibration at least once a year and rectify it if it is no...
Step 1: Gather the Necessary Tools. Before you begin, ensure you have the following tools: Screwdriver. Digital thermometer. Reference thermometer. Step 2: Turn Off Your HVAC System. For safety reasons, turn off your heating or cooling system before you proceed with the calibration. Step 3: Remove the Thermostat Cover.

Remember that a thermostat is just an "on-off" switch that turns heating or cooling ON or OFF in response to the actual room temperature and the desired or "set" temperature you've specified. Make sure that your thermostat is properly set - to "Heat" mode with the fan switch set to "Auto".
