Wade Hampton, SC – AC Contractor FAQ: Signs Your A/C Thermostat is Broken

If your thermostat is not working, it can be difficult to tell if it is broken or if there is another issue. This post will discuss six signs that your thermostat may be broken and needs to be replaced.

Remember that these are some of the signs that your thermostat may be broken. If you are unsure whether or not your thermostat is broken, please contact a licensed AC contractor for assistance.

1) The Temperatures Vary Greatly from Room to Room

If you have a central air conditioning system, the temperature should be consistent throughout your home.

One way to test this is to set the thermostat to one temperature and then go around to each room in your house. If each room’s temperature is different, this is a sign that your thermostat is not working correctly.

Another way to test this is to set the thermostat to one temperature and wait an hour. Then, after an hour has passed, go around to each room in your house and see what the temperature is. If the temperature has changed, this is a sign that your thermostat is not working correctly.

If you notice that the temperature in your home is inconsistent, it’s essential to call a technician to take a look at the AC system. A professional will be able to diagnose the problem by using tools like a multimeter.

2) The Program Setting of the Thermostat is Incorrect

If you have your system on the wrong setting, it can cause significant issues with your thermostat reading the temperature. Most systems will have a “heat” setting and a “cool” setting. If your system is on the heat setting, it will not cool your home no matter how low you set the temperature.

If your system is on the cool setting and you are trying to heat your home, it will not work. Therefore, you must ensure your system is set to the correct setting to function correctly.

Sometimes, the settings keep changing because of a faulty switch. If this is the issue, it needs to be repaired or replaced as soon as possible.

3) The Batteries Are Dead

If your A/C thermostat runs on batteries, they may be the culprit if your system isn’t working. Most digital A/C thermostats will have a low battery indicator to let you know when they need to be changed.

If you have an older model that doesn’t have this feature, check the manufacturer’s website or your owner’s manual to see how often the batteries should be replaced.

In most cases, you’ll need to replace the batteries every two years to prevent them from dying and causing your A/C thermostat to stop working.

4) You Notice the Energy Bills Spiking  

If you run your air conditioner frequently and see a sudden surge in what you’re spending on electricity, it’s worth investigating whether or not your thermostat might be to blame. In some cases, a broken thermostat can cause your air conditioner to run constantly, which will affect your energy bills.

If you’re unsure whether or not your thermostat is the root of the problem, compare your current energy bills to past ones.
