Your AC Stopped Working! Here’s What to Check Before Calling a Pro

Few situations feel as urgent as an air conditioner that suddenly stops working during the Texas summer. The immediate thought is often to call a professional, but sometimes the solution is simpler than you think. 

In fact, a few quick checks may resolve the problem without the need for a service call. Homeowners can safely inspect their thermostat, breaker, filter, and other basic components before picking up the phone. Not only can this save you time and money, but it also ensures you know when the issue really does require professional help. In this blog, we will walk through the steps to check before calling for AC repair so you can troubleshoot with confidence.

Check the Thermostat

One of the most common and easily overlooked issues is the thermostat. If your AC is not turning on, first make sure the thermostat is set to “cool” and the temperature is set lower than the current room temperature. If your thermostat runs on batteries, replace them to rule out power loss as the problem. Sometimes incorrect settings or dead batteries are the only reason the system is not running. Double-checking this simple step can save you the cost of an unnecessary service call.

Inspect the Circuit Breaker

If your thermostat settings look correct, the next step is to check your circuit breaker. A tripped breaker can completely shut down your AC system, making it appear as if the unit has failed. If you see that the breaker has flipped, reset it and see if your AC turns back on. However, if the breaker trips again shortly after being reset, this could signal an electrical problem that requires professional attention. Avoid repeatedly resetting the breaker and call a technician if the issue continues.

Look at the Air Filter

A dirty or clogged air filter is one of the most common reasons an AC stops working. When the filter is full of dust and debris, airflow becomes restricted and the system may overheat or shut down to protect itself. Pull out the filter and check its condition. If it looks dirty, replace it with a new one or clean it if your system uses a reusable filter. Regularly changing filters every one to three months helps keep your system running efficiently and reduces the risk of unexpected breakdowns.

Examine the Outdoor Unit

If your indoor checks do not solve the problem, take a look at the outdoor unit. Debris like leaves, dirt, or grass clippings can block airflow and cause the system to shut down. Clear away anything surrounding the unit and make sure it has at least two feet of open space on all sides. You should also check that the fan is not obstructed and that the unit appears free of visible damage. Keeping the outdoor system clean and unobstructed helps your AC run smoothly and prevents overheating.

Check Air Vents

Sometimes the problem is as simple as blocked or closed vents. Walk through your home and make sure furniture, rugs, or curtains are not covering any vents. Closed vents restrict airflow, which can cause your system to struggle or even shut down. For best performance, all vents should remain open and clear to allow air to circulate evenly throughout your home. Keeping vents unobstructed not only helps the AC function properly but also ensures comfort in every room.

When to Call a Professional

If you have checked your thermostat, breaker, filter, outdoor unit, and vents but the AC still will not run, it is time to call a licensed technician. Certain issues go beyond simple troubleshooting and require expert knowledge and tools. Warning signs include unusual noises, water leaks, burning odors, or a system that runs but fails to cool your home. Repeated circuit breaker trips are also a clear sign that something is wrong with the electrical system. At this point, professional service is the safest way to diagnose and fix the issue without risking further damage to your AC.
