My AC Isn’t Keeping Up

Why a system falls behind on a hot afternoon, what you can safely check, and when to switch it off.

Start With the Symptom You’re Seeing

On a 100 degree afternoon, even a healthy system can run nonstop and still sit a few degrees above the setting. That alone isn’t a failure. The guides below go symptom by symptom (warm air, ice, water, a tripping breaker, short cycling): the usual causes, what you can safely check yourself, and the signs that mean it’s time to turn the system off and let a technician look.

Safety first: ice on the refrigerant lines, water where it shouldn’t be, or a breaker that keeps tripping all mean the same thing: turn the system off at the thermostat. Running it can make the damage worse.

If it comes to that, Gold Eagle repairs air conditioners across the Austin area: see AC service or schedule online.
