Signs Your Air Conditioner Needs Repair

- Frozen coils: If you see ice building up on the copper lines outside or the indoor unit, turn the system off immediately and call us.
- Strange noises: Loud buzzing, rattling, or squealing coming from the outdoor condenser unit.
- Frequent cycling: The AC turns on and off constantly but never reaches the temperature set on the thermostat.
- Water leaks: Puddles forming around your indoor unit can indicate a clogged condensate drain line.
