Signs Your AC Needs Repair

Catching AC problems early can save a hot afternoon. Watch for these signs.

Common warning signs

  • Weak airflow from the vents

  • Warm air when the system should be cooling

  • Ice on the coil or refrigerant lines

  • Water around the indoor unit

  • Strange noises, smells or frequent cycling on and off

  • Higher energy bills with no change in use

Quick checks before you call

  • Check the thermostat settings and batteries

  • Replace or clean a dirty air filter

  • Check that the breaker has not tripped

  • Keep the outdoor unit clear of leaves and debris

When to request service

If the checks do not help, or you see ice, water or hear grinding or banging noises, switch the system off and request service. Photos of the unit and the thermostat help.
