Air conditioning and heating scams you should know

Air conditioning tips .. before you call for AC repairs

Overview: Air conditioning failures are often caused by bad thermostats, a defective contractor or tripped circuit breaker. If your air conditioning fails to start.

Check these before calling us for air conditioning repair:
1) Check that the thermostat is set to “cool” and below the current temperature.
2) Your air conditioner should be on it's own 240-volt circuit; check your homes main electrical panel and secondary circuit panels for tripped breakers or blown fuses. If you find the problem here, reset the breaker or replace the fuse. If the circuit blows again, something is wrong and you need to call us.
3) Make sure the furnace power is turned on and the outdoor condenser’s power switch, (on or near the outdoor unit is on). Check that the 240-volt disconnect next to the compressor (in a metal box, usually mounted on the house wall) is on too.
If the air conditioning still fails to start you need to call us.
