The thermostat is a major contributor to your air conditioner's performance. It shows accurate details regarding the temperature levels in your environment. However, sometimes your thermostat may start failing without your knowledge. If you can't read the initial warning signs, the issues may spread to the entire unit. Additionally, thermostat failures can present themselves in many ways. That said, having your thermostat inspected will help you detect any pending issues and curb them. Below are three signs that your residential AC thermostat is in bad shape. 

It Remains Unresponsive  

You should always observe how your thermostat responds to temperature settings. Some models produce a clicking sound when you adjust the temperatures. Thereafter, your AC starts releasing warm or cool air, depending on the need. If it doesn't respond to the changes, call your technician for an examination. 

Sometimes this issue may arise if the thermostat is too close to rooms with fluctuating temperatures. If this is the problem, your residential AC repair technician will move the thermostat to an interior wall, preferably next to your living room or any other room where you spend a lot of time. 

The AC Fails To Turn On

Many things may prevent the AC from turning on, including a faulty thermostat connection and damaged batteries. A tripped circuit breaker may also prevent it from turning on your AC. But, you need a technician to rule out all these problems. 

You'll need to assess your thermostat's interior to see if everything else is okay. Look out for signs of corrosion or accumulated dirt. If the device is dirty, your technician should clean the soiled parts and test the thermostat. If corrosion is the issue, you may have to consider a replacement to restore AC function.  

Thermostat Loses Its Calibration

Each thermostat has internal programmed sensors for accuracy. After some time of use, these calibrations tend to fade. You will then experience inefficiency and uneven temperature distribution. In most cases, this issue results from inaccurate temperature readings that your thermostat registers. You may also notice the fan turning on and off, which is not only uncomfortable but strenuous to your system. Engaging a reliable technician for recalibration is the only way to solve this problem. 

AC units consume a significant amount of energy when dealing with any faulty component. Therefore, maintaining yours in the best shape will help you avert unnecessary expenses. If your AC thermostat is defective, invest in its repairs or replacement as soon as possible. For more information on residential AC repair, contact a professional near you.
