Does My Thermostat Need to Be Calibrated?

Today’s programmable thermostats have a setting that allows you to manually set the temperature up or down if you find that the reading is wrong.  Manual thermostats do not have this option and often need to be replaced when their reading is inaccurate.

A family in Litchfield noticed that their home seemed colder than unusual, despite the reading on the thermostat.  It isn’t uncommon for a programmable thermostat to need to be recalibrated over time to ensure the most accurate reading.

Checking the Accuracy of Your Thermostat

There are many factors that can cause your thermostat to need to be recalibrated, from accidental bumping to dirt entering the thermostat.  Fortunately, with today’s programmable thermostats this is a relatively easy fix.  The first step is to check the thermostat’s accuracy.  You can do this by taping a glass thermometer to the wall beside the thermostat.  Wait fifteen minutes and then compare the thermometer with your thermostat.  If the reading is off, your thermostat will need to be adjusted.

Most programmable thermostats allow you to make these adjustments yourself, using the settings within the thermostat.  You should refer to the manual for instructions on how to do this for your brand of thermostat. 

Cleaning the Inside of the Thermostat

Dirt inside the thermostat can be a big factor for this inaccurate reading.  You can clean the inside of the thermostat by removing the cover and gently cleaning the inside with a soft, dry brush or cloth.  Removing any dirt inside the thermostat may do the trick, so you should recheck the accuracy using your thermometer after cleaning.

The family in Litchfield was able to manually recalibrate their thermostat and they are now once again comfortable at home.
