Also, the compressor should cycle when the A/C is on. If when the temp inside is above the thermostat and you don't hear the compressor humming outside, its not on and either dead, has overloads that tripped or an electrical problem. If the outside fan doesn't come on, its only a matter of time until the compressor buys the farm. Lastly, do the stupid check and make sure your switch on the thermostat is on auto and cool selected. You have no idea how many times that I have seen the thermostat set wrong. Even by smart people.

I take it you do this stuff for a living?
