Most AC failures in Morris County are not sudden. The system gives warning signs for weeks. If you catch them early, you can avoid an emergency repair during a heat wave.

Warning signs to watch

  1. Weak airflow even with a clean filter
  2. Warm air coming from vents
  3. Unusual noises like banging or screeching
  4. Short cycling or frequent restarts
  5. Higher electric bills with no change in usage
  6. Water or moisture around the indoor unit
  7. The system struggles most in late afternoon heat

What to do now

  • Replace the air filter
  • Clear debris around the outdoor unit
  • Schedule a professional tune-up before the next heat wave
