HVAC Thermostat Problems

It’s more than likely that your home has a thermostat – you know, the mechanism you use to adjust your home’s temperature to a comfortable level. The job of the thermostat is to set the desired temperature for as long as you like.
Let’s briefly talk about how your HVAC thermostat works, common problems you may encounter, and how you can keep it running smoothly.

How Your Thermostat Works

The thermostat’s goal is to keep a stable temperature throughout your house. You request your thermostat to the desired temperature, and the thermostat uses both air conditioner and heater to reach that level. 

The majority of thermostats have either a strip of mercury or a sensor to determine a room’s temperature. From here, the thermostat works like a light switch to turning on to either the air conditioner or the heater. For maximizing the efficiency and your comfort, some modern thermostats are built with smart technology, which is capable of learning the cooling and heating patterns in your home, and how long it takes your place to reach the required temperature. 

Smart thermostats are an excellent option for homeowners looking to upgrade their cooling and heating systems and lower their monthly energy bills.

Problems With Your Thermostat

There are many ways your thermostat may fail. These are the most common problems:

  1. No thermostat display – If the thermostat is not showing a display, it could be a sign of a tripped breaker or a dead battery. If you are sure the power is going, take off the back cover for the thermostat and look for dirt buildup, loose screws, or wiring.  
  2. The temperature does not change to the set temperature – If the thermostat is not making to reach the required temperature, check for a stuck heat anticipator or dirt. This is the part that turns on the heater. If these are not the culprit, a thermostat in direct sunlight at any point is likely to have distorted readings.
  3. Running continuously – If the air conditioner or heater never stops running, it might be that your thermostat anticipator is not working correctly, or there is a buildup of dirt somewhere.

Maintaining Your Thermostat

The first thing you should do periodically to maintain the condition of your thermostat is to clean it and make sure that power goes into the system. Dirt accumulation is a common cause of multiple problems.

Second, make sure that your thermostat is located in a central location and away from direct sunlight. Otherwise, they make your system efficiency go down, making your home’s air unbreathable.
