Thermostats are reliable devices that detect the temperature of your home and will
request changes to balance the temperature of a room to your desired specifications.⌊
Bad Thermostat⌉

Like everything else, thermostats can succumb to wear and tear over time.

A faulty thermostat can end up costing you money in the long run. When was the last
time you checked yours?

Here are the top ways to test your home thermostat.

**Check Thermostat Wiring**

For most thermostats, the face cover should easily pop off using your hands.

From there, check all wires to make sure nothing is loose. A disconnected wire could
be a major factor in a thermostat malfunction.

If you are having issues with the air conditioning system, check the red and green
wires. If it is the furnace that may be giving your trouble, check the red and white
wires.

Important: before you do this, be sure to turn the circuit breaker off.

**Check Your Fuses**

Blown fuses are often times one of the main culprits to a dysfunctional thermostat.
Be sure to check all fuses, loose wiring, and dirt accumulation in your thermostat
to ensure everything is running smoothly.

**Do Some Troubleshooting**

During heating season, set the temperature five degrees higher than normal. During
cooling season, set five degrees lower.

After this step, check to see if your supply vents blow out air or if your return
vents suck air in. This will be a major indicator as to whether or not your thermostat
may be faulty.

**Check Your Batteries**

** **Most digital thermostats have batteries. Be sure to replace any older batteries
to ensure your thermostat is running efficiently.

A healthy thermostat will save you both money and will make sure your HVAC unit 
is not working over time.
