5 Signs That Indicate Your Thermostat Needs Replacing

In most homes in Reston, VA, the thermostat is one of the devices that gets the most use. While it’s usually not a problem to have a working thermostat in your home, there are times when it might be necessary to replace it. If you’re unsure whether you need to yours, read on to learn five signs that indicate it might be time.

Thermostat is Too Old

If your device is more than 10 years old, it’s probably time to replace it. Older thermostats are less accurate and don’t have the same features as newer models. You might not think you need the latest and greatest thermostat, but it’s worth considering if your old one isn’t working as well.

You’re Not Saving on Your Energy Bills

If you’ve noticed that your energy bills have been increasing, it could be because your device is inaccurate. A new, more accurate thermostat can help you save money by ensuring that your home is only heated or cooled when necessary.

Temperature is Inconsistent

Your device should keep your home at a consistent temperature. If you’ve noticed that the temperature in your home fluctuates, even when the thermostat is set to a specific temperature, it’s probably time for a new one. Inconsistent temperatures can be frustrating and make it difficult to keep your home comfortable.

Thermostat is Making Strange Noises

Noises coming from your device are usually signs that it’s beginning to fail. If you hear beeping, clicking or buzzing, it’s time to replace your thermostat. You might not think the noise is a big deal, but it usually indicates a bigger problem.

Inaccurate Readings

If your device is showing the wrong temperature, it’s time for a replacement. Thermostats can become inaccurate over time, so if you’ve noticed that the temperature on your thermostat doesn’t match the actual temperature in your home, it’s time for a new one.

Don’t suffer through an uncomfortable home or high energy bills any longer. If you’re experiencing any problems, call Brennan’s Heating & Air Conditioning. We’ll be happy to help you choose the right thermostat for your home and install it for you.
