Signs you need ac repair
- The house won't cool no matter how low you set the thermostat
- Warm or weak air coming from the vents
- Ice building up on the outdoor unit or refrigerant lines
- A sudden jump in your electric bill with no explanation
- Strange grinding, rattling, or squealing from the outdoor unit
- Short cycling — the AC turns on and off every few minutes
- The system won't turn on at all
