Sometimes, your AC doesn’t do what you actually want it to. It seems like it might have a mind of its own. Maybe your AC unit is constantly running and won’t turn off. If that’s the case, then there are a few simple steps you can take before looking for professional help. There are several reasons why your system might not turn off, and each has a different fix.

Broken Thermostat

It’s possible that you have a malfunctioning thermostat, in which case the AC might not turn off because it doesn’t realize the temperature is already high or low enough. When this happens, you can just replace the thermostat.

Air Filters in Need of a Change

Try changing the air filters. If they’re clogged, they can make your AC work overtime. The same goes for dirty condensers and evaporator coils too, so you may require a tune-up from a professional company like Totally Cool Heating & Air in Austin.

Fan Limit Switch

Sometimes, there’s a manual override for your thermostat’s control of the fan. If the fan limit switch on your unit is set to manual, it may run on its own. You can switch it to auto for an easy fix.

Leaky Ducts

Leaky ducts can be a big problem because the air keeps escaping, preventing temperatures from reaching their desired point. Sometimes sealing around ducts and any other cracks can help take care of that problem.

Low Fan Speed

When your fan is set to a low speed, it has to run a lot longer to do the same job it could easily do at a higher speed. It might be a good idea to change the setting and see if that fixes the issue. However, your fan can also be inhibited by dust and grime. The only way to take care of that is to get a thorough cleaning.

Regular maintenance will prevent most of these problems, and that will save you money in the long run. Here at Totally Cool Heating & Air, we serve Austin and the surrounding area with maintenance, repairs, and more. Contact us today to get more information or to schedule an appointment.
