If your AC just failed, turn the thermostat off so the system stops straining, check your electrical panel for a tripped breaker and reset it once, and replace the air filter if it's dirty. If you see ice on the unit, let it thaw fully before restarting. If it still won't run safely — or the breaker trips again — call a licensed HVAC company for emergency repair rather than forcing it.

At Anderson Heating, Air & Insulation (formerly John Anderson Service Company), we've answered these calls across Calhoun, Dalton, and Rome since 1978. Here's the calm, step-by-step version so you can act fast and avoid making the problem worse.

What to Do the Moment Your AC Fails

Work through these steps in order before you call. Several AC "emergencies" are things you can safely reset yourself.

  1. Turn the thermostat to off. A failed system that keeps trying to run can freeze the coil or overheat the compressor. Shut it down first.
  2. Check the breaker. Look for a tripped breaker to the AC and reset it once. If it trips again right away, stop — that's an electrical fault, not a nuisance trip.
  3. Check the air filter. A badly clogged filter can choke airflow enough to shut the system down. Swap in a clean one.
  4. Look for ice. Ice on the refrigerant lines or indoor coil means the system needs to thaw. Leave it off for a few hours.
  5. Stay cool and call. Close blinds, run fans, and hydrate. If it won't restart safely, call for emergency service.

What Actually Counts as an AC Emergency?

A true emergency is any failure that threatens comfort or safety during extreme heat — especially in a home with older adults, infants, or anyone with a medical condition. Northwest Georgia summers get dangerous indoors quickly when the AC is down. Call right away if you have a complete loss of cooling on a hot day, a burning or electrical smell, smoke, or a breaker that keeps tripping.

Safety first:

If you smell burning, see smoke, or the breaker trips repeatedly, leave the system off and don't keep resetting it. Repeated resets can damage equipment or create a fire risk. Call a professional.

Why Did My AC Breaker Trip and Won't Reset?

A breaker that trips again the instant you reset it is telling you something is electrically wrong — commonly a failing compressor, a shorted capacitor, or a wiring problem. This isn't a DIY fix. Leave the breaker off and call a technician. Continuing to reset it risks further damage.

Why Is My AC Frozen, and Can I Run It?

No — running a frozen air conditioner can wreck the compressor. Ice forms when airflow is restricted (a dirty filter or blocked return) or when refrigerant is low. Turn the system off and let it thaw completely, then replace the filter and restart. If it freezes up again, you likely have a refrigerant or airflow problem that needs a technician to diagnose.

How to Avoid the Next Emergency

Most summer breakdowns trace back to skipped maintenance. An annual professional tune-up, monthly filter changes, and keeping the outdoor unit clear of grass and leaves prevent the large majority of emergency calls — and keep the system running efficiently so it isn't straining on the hottest days. If your equipment is aging, it's worth reading our guide on when to replace your HVAC system before it fails at the worst possible time.
