How to Test Your Thermostat At Home

Do you suspect that your thermostat isn’t working right? Knowing how to test a thermostat can give you peace of mind that your home is going to remain comfortable as the seasons change.

Evaluating your thermostat is a basic task that any North Carolina homeowner can do. Continue reading to learn how to tell if your thermostat is bad and whether it’s time for an upgrade.

Recognizing A Faulty Thermostat

There are certain indications that suggest a thermostat might be malfunctioning. Wondering how to know if a thermostat is bad? We’ve compiled a list below to help you identify some common warning signs.

  • Your furnace or AC doesn’t start. This could indicate a potential problem with the equipment. It could also hint at an issue with your thermostat’s wire connections.
  • The temperature setting doesn’t align with the temperature displayed on your thermostat. Even after adjusting the thermostat setting, there’s still no noticeable change in your home’s climate.
  • The HVAC system constantly runs without taking a break.
  • Your HVAC system is short-cycling.
  • Your thermostat has no power. You might just need to change the batteries, but if there’s something else causing the problem, checking the thermostat will provide clarity.

Now that you’re familiar with some of the signs of a defective thermostat, continue reading to learn how to properly evaluate one.

How to Check If A Thermostat Is Bad – Three Techniques

  1. Initiate A System Check

Conventional AC & Furnace Thermostats: Wondering how to test a furnace thermostat? You’ll need two people to use this method.

One person stands by the thermostat and another near the furnace. Switch the thermostat on, gradually raising the temperature. Both the furnace and thermostat should emit a noise when the furnace “kicks on.” If either remains silent, there could be a problem with the thermostat or even the furnace itself.

This same method can be used for air conditioning systems.

Smart & Programmable Thermostats: You can perform a system check by referencing the user guide that came with your device. Access settings and locate the “Check” option. Observe and follow the prompts displayed.

  1. Clean Your Thermostat

When asking how to test a thermostat, you might not think of simply cleaning it. However, if you have a mechanical thermostat, over time, dust can accumulate and cause disruptions.

To properly clean the device, remove the cover and use a soft brush or cloth to delicately wipe down its interior. Then, put your thermostat back together and simply turn on your system to see if it’s operating properly.

  1. Replace the Batteries

For all electronic thermostats, regular battery replacement is a must. Replace worn-out batteries with fresh ones to confirm battery depletion isn’t the root of any issues you’re experiencing. Try to remember to change the batteries at least once a year.
