Upon arrival customer told me the ac was not working. Another company came out and put Freon in the system about 2 weeks ago. I put my gauges on and it is really low on Freon. Pulled the covers off and there is oil all in the pan. The Evap coil needs to be replaced. Not under warranty. Only collected a diagnostic fee. Owner of home is away and will call if he wants a new evap coil or get a quote for new system.
