A reliable air conditioner is vital during the hot summers, owing to the comfort it offers. This cooling unit operates using essential components, including a thermostat. Ideally, a thermostat regulates temperatures in your indoor space. You can monitor the device and adjust the settings as you please, based on your preference. Unfortunately, your thermostat could stop working due to the following reasons.

Wrong Settings

If your thermostat can't change the temperature in a room, the issue could be the settings. In some cases, the device may be in auto mode. If this is the case, you need to change the settings to cool or AC to enjoy the fresh air. If the settings include options you're unsure about, contact a technician for assistance.

Besides this, the unit could be locked, making it difficult to adjust temperature settings. An expert can help you turn off the feature and restore normal thermostat functioning.

A Dirty Thermostat

A thermostat can fail to work if it's dirty. Over time, dust, dirt, and other particles can find their way into the device's electrical components. Debris can also interfere with mechanical parts in the thermostat, leading to a malfunction.

In such a situation, you need a technician to clean your thermostat. However, it would be prudent to leave the job to a specialist to avoid damaging vital parts within the unit.

Electrical Problems

Your thermostat depends on electrical components to function optimally. In that regard, loose or corroded wiring could be a chief cause of thermostat issues. Additionally, a tripped circuit breaker or a blown fuse might contribute to the device's malfunction.

Lack of power due to dead batteries can be another reason your thermostat isn't working. A new set of batteries can do the trick. If your thermostat has any electrical problems, hire a technician to fix them.

Faulty Sensors

If the sensors in your thermostat are faulty, the device won't work as it should. As a result, your air conditioner won't turn off when your indoor space reaches the desired temperature. The worst part is that your home might become overly cold because your AC is running non-stop.

Malfunctioning sensors contribute to high power bills at the end of the month. You can remedy the situation by hiring a technician to check your thermostat's sensors. The expert will ensure that the device communicates correctly with the AC for correct cooling.

The above are reasons why your thermostat could be having trouble working. A professional service such as Carolina Air Care can fix the issues through AC repair.

Troubleshooting HVAC Issues

About a year ago, I realized that our air conditioner just wasn't cutting it. Our home was constantly hot and humid, even though our air conditioner was running almost all the time. In addition to driving up our energy bill, my entire family was tired of sweating constantly. To resolve the problem, we decided to hire an HVAC contractor to come out and fix the problem. He figured out that our compressor was damaged, and he replaced it for us. After that, our system ran great again.
