Whether you’re hot or cold, want to warm up your home or cool it down, the only place you go is to your thermostat. Move the lever just a little, and you’ll soon feel a whoosh of conditioned air helping to make your home a more comfortable place to be.How To Fix My Thermostat

If you don’t have a working thermostat, you won’t have the ability to warm and cool your home the way you desire. No matter how you adjust it, the HVAC system won’t respond the way it should. And that means it’s time for a repair.

If you’ve owned your home for any length of time, you’ve probably turned into quite the handyman. There are a lot of things you can do yourself, after all. And why not give it a go before you have to call in a professional? It might be easy. It might be something you can fix with just a few minutes of tinkering, saving you money in the process.

Why shouldn’t you take a crack at fixing your own thermostat?

Because it might not be your thermostat at all.

Your HVAC system is one of the most complex systems in your home. And that complexity makes it tricky to find out exactly what’s wrong when something starts to malfunction. It’s easy to assume that if the furnace or air conditioner refuses to turn on when you turn on or adjust the thermostat is the thermostat’s fault. And it might be.

But there are numerous other possibilities. It could be a broken blower fan motor. Or overflow in the air conditioner condensate pan.

Assuming the thermostat is the problem is only touching one piece of the puzzle. And because there are so many other pieces with potential for being a part of the problem, attempting to fix just that one piece could leave you with even more trouble.

There are a few things you can do before you call in a professional.

First, check the circuit breaker panel. In some cases, the circuit breaker for the AC or furnace has tripped, even if the thermostat still has a display. This is one of the most common reasons for the HVAC system to refuse to turn on. Reset the breaker and try it again.

Next, turn the thermostat to the opposite setting. If you want AC, turn it to the highest setting for your furnace, for example. If nothing happens, it is probably your thermostat.

If the digital screen on your thermostat is blank, it could be your batteries have worn down. This usually only takes prying the front cover off to make the change. Be sure to brush away any dust that may have accumulated inside the thermostat.

If you still can’t figure it out, it’s time to call in a professional. They can quickly walk through a checklist and determine where the problem originates from. They can also help make suggestions on where to save money within your system.
