Signs You Need Emergency AC Service

Sudden stops or erratic behavior from your AC unit are clear signs of a problem, but there are other indicators that you need emergency air conditioning repair. You may notice water leakage around the unit, strange noises coming from it, odd smells in the room it’s located in, or dust and debris blowing out of vents. If you notice any of these signs, call Cotti-Johnson immediately for emergency AC service.

Can I Fix My Own AC?

Tinkering with your AC unit can be dangerous and should be left to professionals. Not only could you potentially hurt yourself, but an inexperienced homeowner or repairman might cause more damage or miss the underlying issue altogether. Some steps you can take before one of our technicians arrives include checking the circuit breakers and fuses, ensuring all vents are open, and cleaning up any water leakage to prevent water damage to your home.
