Telltale Signs of a Bad AC Thermostat – Our Guide

Sometimes you don’t realize that your thermostat is broken until summer comes around. It is important that you understand the common symptoms of a bad home thermostat so that you can fix the issues before it becomes more serious in the long run. Failing to repair your thermostat until you really realize that it’s having a problem can lead to more serious, more expensive issues. Fortunately, most thermostat problems don’t come out of the blue. There are some warning signs that present themselves early on that can indicate that your AC needs to be repaired. Here are some of the symptoms that you can look for so that you can quickly fix your unit before it’s too late:

Your HVAC unit doesn’t start

This might be an obvious one but one that is hard to diagnose. A wiring defect could cause your thermostat to lose connection to the heating or cooling system, which may be the issue. Your system could also be reading temperatures incorrectly and not turning the cooling or heating on when it is needed. Whatever the issue, the symptoms require a professional to inspect, assess, and repair the unit. If your heater or air conditioner is malfunctioning and your system will not start, call in an expert.

Your air conditioner runs perpetually

If you are noticing that your air conditioner keeps running without turning off, this can be a malfunction that has to do with the wiring. The wiring that turns your heating and cooling off might be broken, or the thermostat might be miscalibrated. This means it is sending off the wrong signals to your HVAC system.

New batteries don’t work

If you have already tried changing the batteries in your thermostat without any luck, then you will need a professional to come to help you with the issue. Sometimes changing the battery of your thermostat when it’s acting strangely can be the trick but if it isn’t, don’t hesitate to call.

Temperatures vary in different areas

If the temperatures are varying as you walk through at your house, this is a sign that something isn’t right. Temperature shifts will occur if your HVAC system turns on and off when it’s not supposed to be doing so. As a result, the rooms in your home will vary in temperature and you may feel hot or cold spots in different areas. The rooms in your home that are further from your central unit might not receive an even distribution, meaning that there is a malfunction.

Your thermostat is unresponsive

If your thermostat is malfunctioning when you adjust the temperature or does not respond to the changes in temperature at all, you will definitely want to find someone who can assist you with your problem. There is also a possibility that your display light is not working or your interface is unresponsive. Either way, you will need the help of a professional.
