Troubleshoot Your Thermostat

Waking up or coming home to an HVAC not working can be the scariest for Central Texas home owners, especially before summer hits. A broken thermostat may be the only culprit, so we wanted to share some tips and tricks on checking on that before you start to stress that it is your entire system.

First of all, what is a the function and purpose of a thermostat?

A thermostat is basically a heat-activated switch that uses an internal temperature sensor to open or close a switch to turn on your system. The thermostat is there to tell you the current temperate and activate your furnace or AC to the temperature you have set.

The temp in my house is off, what move should I make first?

Oftentimes, basic things are frequently overlooked- like checking to make sure the thermostat is even on. The first step is confirming power and that your circuit breakers are operating properly. Checking to make sure the actual thermostat has charged batteries is another “Captain Obvious” move, but one we have all overlooked before.

Wipe it down

Dirt, pet hair, and dust can make their way inside your thermostat, clog the thermostat and interfere with both electrical and mechanical components.

You can use a Q-Tip or a small paintbrush or a can of electronics air cleaner designed for electronics. If you are uncertain about how to do this correctly, call Airtech to schedule an appointment to avoid damaging the sensitive components. We got you!

Where is it located?

Remember being young and putting the thermometer near a lamp to appear ill and stay home from school? Putting a thermometer in a heated location will inaccurately raise the temperature and cause your thermostat to give you a bad answer. Also, make sure the holster and components level, the mercury used in conventional thermostats will not register correctly if uneven.

Breathe and reboot

To do this: set your thermostat to heat and lower the temperature until the furnace shuts off. Go to your breaker panel and turn off the power to your thermostat and furnace system. Leave the breaker switch off for about a minute, and then turn your breaker back on.

Time to update?
