The thermostat is the command center for your residential HVAC system. When something goes wrong with this essential component, you may not be able to get comfortable, even if the rest of the system is operating fine. While you should always seek professional assistance for heating and cooling issues, here are a few possible causes of a malfunctioning thermostat. 

What Problems Can Affect Your Thermostat?

1. Display Dysfunction

If you have a newer thermostat, you most likely have a digital display. This is where you'll see the temperature, as well as other settings. If the display is no longer visible or is obscured somehow, it will be impossible to maintain a reasonable temperature in your home. 

Replacing the batteries can sometimes fix display problems. However, a wired device may require a replacement when the display stops functioning. 

2. Old Age

An older device can also experience a range of issues. If it's no longer level, the mercury bulb inside won't provide an accurate reading. If components are worn or broken, the device might not receive the power it needs to operate. The average life span of a thermostat is about ten years, so consider scheduling a replacement with a residential HVAC professional if yours is nearing that age or is older. 

3. Dirt & Dust Buildup

The accumulation of dirt, dust, and debris within the unit can also contribute to wear. It can impact temperature readings as well, which can lead to a home that's unevenly heated or cooled. 

You can prevent dust accumulation by cleaning the device once a month. Use a microfiber cloth and wipe down the thermostat to stop dust and debris from getting inside.
