If you frequently feel too warm or too chilly, but your thermostat is displaying what should be a comfortable temperature, its accuracy may be off. An inaccurate thermostat not only has an impact on the comfort level in your home, it can affect the length of your HVAC system cycles and increase the equipment’s energy consumption. Here’s what to check for to make sure that your thermostat temperature is right.
If you haven’t taken cleaned the inside components in a while, built up dust and debris may be preventing it from reading the room temperature properly. Cleaning a thermostat is easy — just take off the cover and use a soft-bristle brush to remove any accumulated dirt. Then, clean the metal contacts with a cotton swab dipped in electrical contact cleaner.
An out-of-whack sensor can prevent the thermostat from reading and displaying the correct temperature. Re-calibrating the unit may solve this problem, but if it doesn’t, you’ll have to replace it.
Out of Level
If you have an older mercury thermostat that’s been bumped and put off level, it may not work accurately. You can adjust the thermostat’s positioning by setting a carpenter’s level right above it and moving it carefully until it’s back on level. If this doesn’t improve its accuracy, it’s time to invest in a new thermostat.
Where the thermostat is situated in your home has a direct correlation to how well it performs the task of reading the right temperature. Make sure it’s centrally located out of direct sunlight and and away from drafts, HVAC registers and heat sources. You may need to have it relocated to improve its accuracy.
If you have an older thermostat and it’s still not reading properly after you rule out all of the above issues, retire it. By upgrading to a programmable or Wi-Fi thermostat, you can increase comfort, boost energy efficiency, and take advantage of the latest convenience features, too.
