HELP! York Diamond 90 no air out of duct

The unit is about 5.5 years old. I had similar problem last year when I first started the AC in the summer. There was no air coming out of duct. Last year I had it on for a day and had condensation along the coolant line then I turned if off and mysteriously it just started a week later when I tried again. I had a HVAC guy came over anyway to check everything out, he spent an hour and told me there was no problem that he could found.

This summer I turned on the AC again and the fan outside is running but no air coming out of duct. Where should I check? Anybody have the schematics of the unit? Am I better off calling for a service guy again?

Any help is greatly appreciated!

 

I think your inside fan stop working. It can be a number of problems, better call a Tech. Don't run your A/c anymore, without the inside fan, it may damage your system.
