With how hot the summer days are becoming, more and more homeowners are finding that their AC unit is a vital part of their home in Chattanooga, TN. Understanding the different parts that make up your AC unit and what they are responsible for can help you better diagnose a problem.

One of the most common parts that often need AC repair services is the programmable thermostat. This is an important part of any AC unit, as it controls and regulates what the AC does. If it is not functioning properly, you will not get the results that you want. Either your home will not cool down to the desired temperature or it may not even cool down at all.

Here are four signs that you need to replace your programmable thermostat or, at the very least, call a professional for AC repair services.

#1. The AC Unit Won’t Turn On or Off

One of the first signs that there’s something wrong with your AC unit and that it needs some type of AC repair is if the AC unit won’t turn on or off. When you adjust the programmable thermostat, it will send a signal to the unit telling it to turn on or off and to start or to stop cooling the air inside your home.

One of the first problems that ever emerges with programmable thermostats involves the wiring. If there is indeed a problem with the wiring, your AC unit won’t receive any sort of signal whatsoever. Due to this reason, it won’t turn on or off. You can usually determine if the thermostat is to blame if you place a thermometer beside the thermostat to check whether the thermostat is accurately measuring the temperature.

If the thermometer is registering a completely different temperature than what is shown on the programmable thermostat, then you’ll need to get a professional to come in for AC repair services immediately. Our professionals may be able to reconnect the wiring during the repair services or they may recommend replacing the thermostat entirely depending on how old it is.

#2. The Thermostat Is Unresponsive

Another common sign that you need to replace your programmable thermostat is if the thermostat is unresponsive. This means that it either responds inconsistently when you try to program it or it doesn’t even work at all. There are many reasons for why this might be happening. It could be a power issue or it could be a wiring issue. It may also be an indication that there are malfunctioning or broken parts inside.

The first thing that you should do is to replace the batteries inside the thermostat. If that doesn’t help or work, then you should call one of our licensed contractors to come out for AC repair services.

#3. The Temperature Is Inconsistent

If you’ve noticed that the temperature throughout the entire home is rather inconsistent, it could also be a sign that there’s something wrong with your programmable thermostat. It is also sad that you need AC repair services if certain rooms are cooler or warmer than others despite the fact that the AC is circulating within the entire home. The only exception is if you have an AC unit that can cool rooms individually.

When these things happen, the first parts that you should look at is the thermostat. With that said, other parts can also be the culprit.

#4. The Temperature in the Room and the Thermostat Settings Are Off

Have you noticed the temperature inside the room and the thermostat settings to be off? For example, did you set your thermostat to say 20°C but notice that the room is a consistent 25°C? The opposite could also be true. You may have set the thermostat to 25°C but noticed that it is consistently at 20°C.

In these situations, there’s a good chance that you don’t need to replace the thermostat completely. You may need to, however, clean the thermostat using compressed air. If you don’t know how to disassemble the AC unit or access the thermostat, give a professional heating and air company a call. Usually, regular maintenance will include cleaning these parts.

BONUS: Programmable Settings Are Lost

Some homeowners and experts find that it is time to call in a professional for AC repair services or to replace the thermostat entirely when the programmable settings are lost.

This could be due to a variety of reasons. It could be due to a faulty circuit board and more. Many experts recommend replacing the thermostat when this happens because it is near the end of its life. With that said, this isn’t a rule. You can always ask our professionals to diagnose the situation and see whether there is a suitable solution. If the AC repair will be almost or more expensive than replacing the entire unit, you should go with the latter.
