Is It Time to Replace Your Thermostat?

Gent Heating & Cooling

When it comes to keeping your home at a comfortable temperature, an efficient HVAC system is essential. That means you need to keep it in good working order with regular maintenance. One of the most important components of any HVAC system is the thermostat. It is your main line of communication to the system and controls how hot or cold your home or place of business is. That means it is essential that you replace it whenever it develops faults.

Let’s take a look at a few of the tell-tale signs that your thermostat may be ready to replace!

1 - Your HVAC System Turne On or Off Unexpectedly

One of the primary functions of your thermostat is to communicate with your HVAC system and send signals to increase or lower the temperature. If your HVAC is no longer responding to those signals or is not coming on when programmed, it could be a sign that the thermostat is faulty. There are a number of issues that could cause such a fault, including damaged wiring. A qualified service technician can take a look and determine if it is time for you to replace your thermostat or if they can repair it.

2 - Incorrect Thermostat Readings

We rely on thermostats to make sure our spaces are not getting too hot or too cold, so if they register an incorrect temperature reading, it can be cause for concern. It is easy to double-check, but placing a portable thermometer in the room and comparing the reading to what the thermostat is displaying. If there is a significant discrepancy, then it is likely your thermostat requires replacement sooner rather than later!

3 - High Energy Bills

Have your energy bills suddenly spiked? If your HVAC system is not working efficiently, it can push your bills higher. In most cases, the culprit is a broken thermostat.

4 - Frequent Temperature Changes

When your thermostat is nearing the end of its life, it may have difficulty maintaining a steady temperature. If you find that your HVAC system is frequently changing temperature with no warning, then it could be time to get an updated thermostat.
