When the Louisiana heat kicks in and your air conditioner won’t budge, your first thought might be: why is my AC not working? At Summers Comfort Heating & Air, we get this question all the time from folks here in Denham Springs, LA. Truth is, there are several things that could be going on—and many of them are easier to fix than you’d think.
Let’s break down the most common issues, so you know what to look for before calling in the pros.
Check the Thermostat First
Sometimes the solution is simpler than expected.
If your thermostat is blank or set incorrectly, your AC won’t run. Double-check that it’s set to “cool” and that the temperature is lower than the room temperature. Also, make sure the batteries aren’t dead. This small fix often solves the problem when customers ask, ‘why is my AC not working?
Why Is My AC Not Working? Check the Air Filter
A dirty filter can shut everything down.
When filters are clogged, airflow becomes restricted. That can cause the system to overheat or freeze up. Try replacing the air filter—ideally every one to three months during peak seasons. It’s a small step that can make a big difference.
Is the Breaker Tripped?
Electrical issues can stop your AC cold.
Go to your breaker panel and see if anything has tripped. If the breaker for the AC system is off, flip it back on. However, if it keeps tripping, that could point to a deeper issue. In that case, it’s best to call us at Summers Comfort before further damage occurs.
Why Is My AC Not Working? Inspect the Outdoor Unit
Sometimes, the problem is sitting right in your backyard.
Take a look at your condenser outside. Is it covered in leaves, debris, or dirt? Is the fan running? If debris blocks the unit or the fan stops spinning, restricted airflow or a failing motor could be to blame. Either way, this might be the reason why is my AC not working the way it should.
Listen for Strange Noises
Unusual sounds often mean trouble.
If you hear grinding, buzzing, or clicking sounds when your system kicks on (or tries to), something could be loose or broken. Strange noises can lead to bigger problems if ignored.
Frozen Evaporator Coil
Yes, ice can actually mean it’s too hot.
A frozen coil often results from low refrigerant or poor airflow. You might notice ice on the indoor unit or warm air coming from your vents. If that happens, turn the system off and give us a call. Trying to run it in that state can cause more damage.
Refrigerant Levels Might Be Low
And that’s not something you can fix on your own.
Low refrigerant often means there’s a leak. If your system blows warm air or takes longer than usual to cool your home, that could be the cause. Only a licensed technician (like one from our Summers Comfort team) can recharge the system properly and fix the leak.
Your AC May Be Old or Undersized
Sometimes, the unit just isn’t up for the job.
If your system is over 10–15 years old, it may be reaching the end of its life. Or maybe the installer didn’t size your unit correctly for your home’s square footage. Either issue could be the answer to why is my AC not working effectively anymore.
