AC Programmable Thermostats: When Is the Right Time to Make a Replacement?

A programmable AC thermostat is helpful in ensuring that your home remains comfortable. When it's functioning correctly, it is effective in adjusting the temperature in your home. However, like most equipment, it may eventually fail. That said, you can catch and address early signs of failure to avoid discomfort and unlivable conditions in your home due to unexpected failure. Here are a few signs that point to a failing AC thermostat:

The Thermostat Doesn't Respond to Thermostat Changes

Once you change the setting on your thermostat, the changes should take a short time to reflect. Usually, you notice a slight clicking sound, and your air conditioning unit turns itself on. Accordingly, if you don't hear this sound, or if your AC doesn't turn on after making a temperature change, your thermostat is faulty and likely needs to be replaced.

Your Thermostat Constantly Switches Itself On and Off

Your air conditioner relies on the signals it receives from the thermostat so it can shut down or turn on. The same goes for signals relayed to the air conditioner when your thermostat gives inaccurate readings. The resultant inconsistency may cause your AC unit to turn off too early, failing to complete the cooling cycle. If this happens, you might notice that some sections of your home are cooler than others. Fortunately, a knowledgeable air conditioning repair expert can address such an issue effectively.

Your Air Conditioner Doesn't Turn On

Certain issues with your thermostat may cause your air conditioning unit not to turn on. For instance, if you changed the thermostat recently and your unit doesn't turn on, your device is likely mismatched to your AC. The issue of failing to turn on can also arise if your thermostat has a wiring problem. Even so, in case your AC repair technician checks these issues and determines that they're not the source of the issue, they check whether the issue could be with your air conditioner.

Your Thermostat Doesn't Display Anything

An optimally functional thermostat should never be blank. Rather, it should continuously display your home's time and current temperature. Thus, if it goes blank, the component is likely problematic. Different things can cause a thermostat to go blank. For example, it could be that the battery has died, or the wiring is faulty. The component may also be blank if your AC condensate drain pan is full. Engage an experienced AC repair contractor to thoroughly inspect your unit and advice on the need for repairs or replacement.

You require a working AC to keep your indoor's temperature bearable during the hot season, and the thermostat plays a crucial role in ensuring effective adjustment of your home's temperature. This guide should help by pointing out some common signs of failure you can watch out for.
