The thermostat is the control center of your HVAC system. Without it, you couldn't manage the climate inside your home, so it is crucial to have a faulty device checked out by an HVAC repair professional as soon as possible. To better understand what's causing the problem, here are three common reasons that thermostats break down.

What Are the Most Common Thermostat Issues?

1. Inadequate Installation

While it might seem like a fairly straightforward device, a thermostat is actually a sophisticated piece of equipment. If a past homeowner installed it themselves rather than leaving it to an HVAC repair professional, there's a chance that the unit isn't wired correctly or that the wires have come loose. 

Also, placement is important. If the thermostat was installed in a naturally warmer or cooler spot, such as in front of an east- or west-facing window or in a windowless interior room, the unit might not be sensing temperatures correctly.

2. Age

Thermostat technology has advanced considerably in recent years. All you have to do is look at a thermostat from 40 or 50 years ago and compare it to those that are in widespread use today. 

If you have one of these earlier versions, it could be well past the end of its life span and starting to break down. The average thermostat's life is only about 10 years, so if yours is reaching that point, it may not be as effective or efficient as it once was.

3. Dirt Buildup

The internal components of the device will naturally accumulate dust, dander, and other grime. The buildup can clog wiring and connectors and impair the functioning of the thermostat. With an old, dial-type unit, you might only need to remove the cover and dust it off. However, because of the technical components of newer units, an HVAC repair service should handle the thermostat's cleaning needs.
