Your thermostat may be a small device with a tiny screen, but it plays a big part in your overall comfort at home.  This nifty device allows you and your family to deal with extreme weather and remain cozy. However, due to its straightforward task, it tends to be ignored and most homeowners only pay attention to their thermostat begins to act up. Most of the time, thermostats do their job virtually unnoticed — without requiring much interference on your part. However, when it stops working, your whole family is affected.

What is a Thermostat?

A thermostat is a device that controls the temperature in an HVAC system. It enables you to set a preferred temperature and works to keep your room at your desired level. When your furnace or air conditioner reaches your set temperature, the thermostat will turn the system off to prevent it from overheating.

How to Know When Your Thermostat is Not Working Properly

The HVAC System Wont Start

One of the easiest indications of a faulty thermostat is the failure to turn on your HVAC system. Whether it’s your furnace, heat pump, or air conditioner, the system just wouldn’t start. When this happens, you may assume that the entire system is not working, but it could be the thermostat that’s causing the problem.

The first thing you need to do is determine the thermostat has power. If you have a regular thermostat, be sure to know where the batteries are located and replace them with fresh ones. If you have a wireless thermostat, it likely uses AA Lithium batteries instead of regular ones.

If your thermostat is attached directly to the wall, check for blown fuses and tripped circuit breakers. These issues prevent your thermostat from doing its job.

The HVAC System WontStop

Sometimes, it’s the opposite that occurs: the unit refuses to stop. This isn’t a simple issue. When an HVAC system fails to shut down, there’s a possibility of electrical and wiring issues. If your furnace or AC and thermostat are both old, you could expect damaged electrical wires and similar problems. This situation requires professional attention. You shouldn’t work with electrical problems unless you have proper training and tools.

The Thermostat is Old and Inefficient

Older thermostats tend to show performance issues. Electronic or mechanical thermostats will stop working at some point, and replacing parts doesn’t always fix the problem. You would probably have to replace it when it shows signs of malfunction. Doing so will help you get rid of such unnecessary troubles.

The Thermostat Fails to Respond

Sometimes, you touch your thermostat screen, trying to change the settings, but it does not respond. Such a case is a clear indication of a faulty thermostat. It may seem like a huge problem, but sometimes, changing the batteries or cleaning the thermostat does the trick.

A buildup of dirt and grime can cause discrepancies between your temperature settings and the actual room temperature. This means that the thermostat needs cleaning. To clean the unit, gently dust off the inside of your thermostat. If your brush is too large and can’t fit within the plates, try sliding a soft paper back and forth to clean them.

If these steps don’t solve the problem, it may indicate an electrical problem. Same as above, it’s best to call a qualified technician.

The HVAC System Delivers Air Unevenly

Inconsistent heating or cooling may not be as serious as an HVAC system that does not work at all, but it still causes inconvenience to you and your family. If you notice a significant difference in the temperature between rooms, a faulty thermostat might be the culprit. When it fails to work properly, it randomly turns your HVAC system on and off, which results in hot and cold spots. This problem may require you to call a professional.
