What’s Wrong With My Thermostat?

Improper Installation

Some thermostats need to be level to read your home’s temperature properly, so if yours was installed wrong or got knocked out of place, you may just need to make sure to put it back where it’s supposed to be.


If the sensor on your thermostat is dirty, it won’t be able to get an accurate reading of your home’s temperature. Clean it by removing the cover and dusting it with a soft brush.

Poor Location

If your thermostat is not centrally located, is in direct sunlight or near drafts, it won’t be able to get an accurate reading. Make sure your thermostat is at least 5 feet above the floor and in an area away from sun, vents, or outside doors.


If you have an older thermostat, it could be reaching the end of its life. Consider upgrading to a newer smart or programmable model like a WiFi thermostat for an accurate temperature reading. These are more expensive than a traditional thermostat but you’ll end up saving money on energy bills.
