What’s Going Wrong With Your AC?
We’ll Find Out — and Fix It Fast
Even a small issue with your AC can lead to big discomfort — especially in San Antonio’s heat. If something doesn’t feel right, here’s what might be happening:
Your Home Isn’t Getting Cool
If your system is blowing warm air or struggling to hit the thermostat setting, we’ll pinpoint the cause and get your comfort back on track.
You Hear Odd Sounds
Grinding, rattling, or buzzing? Those noises usually mean something’s come loose — or worse. We’ll inspect it before a small issue turns into a costly repair.
It Turns Off and On Constantly
Short cycling can signal electrical issues, poor airflow, or a failing part. It wears your system down fast — let’s stop it early.
You Spot Leaks or Notice Moisture
If you see water pooling or notice icy coils, it could be a refrigerant issue or blocked drain. We’ll fix the leak and protect your system from further damage.
The Airflow Feels Weak
Some rooms cool fine while others feel like a sauna? Poor airflow can mean clogged filters, ductwork problems, or fan issues. Our technicians inspect and balance your home cooling systems to restore even, consistent comfort throughout your home.
