Sometimes, resolving the problem with an improperly working heater or air conditioner is simple: start with troubleshooting your thermostat. It's an easy place to begin! Should the problem with your HVAC system lie with your thermostat, you may be able to fix the problem without expert help.
Trick #1: Check the batteries.
Make sure the batteries are fresh. Since it's so easy to do, it should be the first troubleshooting step you take, especially if you have a wireless thermostat. Of course, if your thermostat is AC powered or mechanical, batteries aren’t a consideration.
Trick #2: Check the thermostat temperature sensor to make sure it’s accurate.
Turn the thermostat on and see what temperature it reads. Check this temperature against a thermometer you know is accurate. The thermostat should read the same temperature as your separate thermometer. If not, calibrate your thermostat; the thermostat’s user manual should tell you how to do this.
Trick #3: Check the wire connections of the thermostat.
This trick might require removing the cover or thermostat from the wall, but you’ll need to make sure there isn’t a loose or deteriorated wire somewhere. If you do see problems with the wiring, that’s a sign it’s time to call in the pros.
Trick #4: Clean the thermostat.
If the thermostat cover or inner components have layers of dust, carefully removing the dust with canned air or a soft brush can help. This is especially useful for making sure the mechanical contact switches are working properly.
Trick #5: Check the thermostat’s location.
Is your thermostat placed right above a lamp or next to the kitchen? Incorrect placement can result in the thermostat turning on and off at improper times. That's because it thinks the ambient temperature is warmer than the majority of the house is.
