There are a few tricks to make sure that your thermostat is functioning properly.
For one thing, if it’s a programmable thermostat you’re going to want to figure out how it works.
Read the instruction manual carefully. That way, you will know when there’s a real problem and not something that you are simply ignorant of because you don’t know the ins-and-outs of the thermostat. This can truly save you a service call. If you don’t quite understand how your programmable thermostat works, you might call out an HVAC technician because you’re convinced that either the heating or the air conditioner unit is not working properly. I can be pretty embarrassing when an HVAC technician simply keys in a few commands to your thermostat and everything is working fine again! It can also be expensive if they charge for the visit. Even if you know the ins-and-outs of your programmable thermostat there are other things that you should be aware of. If the thermostat doesn’t seem to be responding, or its power seems to be cutting in and out, or it’s completely off, there’s a good chance you need to change the batteries. Fresh batteries can solve a lot of problems. Also, try to keep objects that can influence the thermostats sensors away from it. For example, if a lamp is shining directly on the thermostat, it can influence whether or not the thermostat is able to tell when the air in the home is cool enough to shut the HVAC unit down. Keep anything that can generate heat far away from the thermostat so that it is not confused!
