What Would Cause My Thermostat to Stop Working ?

February 22, 2021

Escambia county, FL, gets hot in the summer, meaning your HVAC system needs to be in great working order at all times. The thermostat is a homeowner’s only way to interface with the air conditioner to tell it how much to cool the home. The following are some reasons the thermostat in your home could malfunction.


Your thermostat’s issue may not be with the device itself at all. In many instances, it’s the power source causing the device to work improperly or not at all. If you’re having power issues with your thermostat, have an HVAC technician check the power going to it to ensure there won’t be any future issues once it’s installed.

Thermostat is Old

If your thermostat is more than 10 years old, it could be nearing the end of its lifespan. On top of this, older thermostats have outdated technology. This means it won’t offer the smart programming features that a modern one can.

Thermostat is in a Bad Location

Is your thermostat installed in an area where it gets a lot of direct sunlight? This is a bad idea because it causes the thermostat to read the temperature as hotter than it is. Not only does the constant direct sunlight cause exterior wear and tear on the unit, but it also forces your home’s HVAC system to work harder than it needs to.

Programming Issues

Modern thermostats have a variety of functions never seen before in HVAC technology. If there are any issues with these components of the software used to run the it, a professional will need to remedy the issue.
