It seems every year when I use this air conditioner for the first time there is a secret switch or command that I have to do to get it working.

Does anything start with the outdoor unit? Have you checked the breaker or disconnect on side of house?

nothing run outdoors - the only thing I hear and feel is the fan - not the fan on the air conditioner outside but the lower fan??

Thank you.
The part outside runs on 240 volts...2 separate 120v lines.
Are you comfortable getting into the outdoor unit?
Do you have a voltmeter?

Hello again, Billy had to leave. Tell me when you have a volt meter so that you measure the voltage **between** the the two power lines that feed the unit, you can measure at on the bottom side of the disconnect switch or fuse block mounted on the wall next to the unit. It should read 230 volts approximately. If you have power there, I need you to send me clear, well focused, close up photo's of the wiring diagrams glue to the inside the furnace or air handler service panel, and the electrical controls box cover inside of the unit that sits outside. Use the paper clip icon above your reply box for that. We can go from there. .

Please hold your rating until we get the system fully diagnosed, so far we are on step one of information gathering.
