Will a New Thermostat Fix My HVAC Issues?

Your thermostat controls your HVAC system and enables it to run efficiently. A broken or outdated device will interfere with the comfort of your Clinton, TN, home. Here are several indications that it’s time to replace your thermostat:

High Energy Bills

A suspiciously high energy bill may signify that your HVAC system is inefficient. In most cases, the thermostat causes this issue by failing to read the temperatures correctly.

Consequently, the system overworks and consumes more power trying to maintain comfortable temperatures. If you’re experiencing this issue, consider replacing your thermostat with a programmable model.

HVAC Systems Keeps Turning On and Off

A thermostat controls the HVAC system by sending signals to lower or increase the temperature. This means that when the device develops a problem or becomes outdated, it stops sending these prompts and compromises its connection with the system.

Consequently, your HVAC system starts turning on and off unexpectedly. This problem can cause premature tear and wear and increase your energy bills.


A faulty thermostat causes the HVAC system to shut down earlier than expected. This happens because the system doesn’t complete a heating or cooling cycle.

If left unresolved, this issue can cause affect the performance of your HVAC system. Therefore, hire a service technician to check whether you need to replace the thermostat or install a new HVAC system.

Constant Temperature Shifts

A damaged thermostat is unpredictable because it changes temperature settings unexpectedly. It may also have faulty readings or fail to respond to adjusted settings. This issue can make your home extremely hot or cold during summer.

To confirm it, you can use a portable thermometer to test whether the thermostat’s readings are correct. Alternatively, lower the device’s settings and see what happens after the test trial.

Typically, the HVAC system makes clicking sounds and starts immediately. If it doesn’t do so, the thermostat has an issue and needs urgent replacing.

In summary, a thermostat should work well for your HVAC system to run efficiently. Schedule an appointment with our service technicians at Melton Heating and Air Conditioning for professional AC repair services.
