My air conditioning unit is blowing air, but not coolingWhat could be the problem?

The outdoor unit is not coming on. Could be the 2 wires from airhandler to the coil on the contactor is bad from weedeater or dog chewing on them. Could be the coil on the contactor is bad or contactor itself. Dheck the breaker to insure they are on and fuses at disconnect are good. Are you getting 220 volts to the contactor? Could also be the fan or compressor at oudoor unit. You will need to do some checking and post back with results
