Is outdoor ac unit coming on?
Can you tell if the compressor is actually coming on or just the fan in outdoor unit?
No that is just the blower. The COLD is made by the compressor in the outdoor unit.
Go to outdoor unit.Se if fan is running in that unit.Then listen for a deep sound coming from down in the unit.Also feel of the large copper refrigerant line where it enters the outdoor unit and see if that line is cold like a soda out of the fridge
Is thermostat still calling for ac ?
Ok you may have more than one issue if fan has gone off also.
OK if copper line is warm, either compressor s not coming on or system is low on refrigerant.Is the outdoor fan actually turning?
OK .That is good.When you say copper line is warm, do you mean like same temp as outdoor air or warmer than outdoor air?
Sounds like maybe compressor is not running.Do you have refrigerant gauges to connect to unit?
I think our next step is going to be to verify if the compressor is coming on.Gauges is easiest way.Do you have a clamp on amp meter we can clamp around one of the compressor wires and see if it is drawing any power?
Unfortunately without one or the other it is going to be necessary obtain them or call n a technician with tools.
Wish it were something simple like something we could obviously see, but in most cases we need tools of the trade for troubleshooting.I a more than willing to help, but only so much we can check visually.Sort of like having a technician show up to troubleshoot without his tools.Since we can't "see" voltage or pressures, the tools are necessary.
