This is crazying I'm going through the exact same thing here at my house. Only thing is noone can even suggest what they feel the issue is. My R22 is full we are getting a 18* temp drop at the unit. However the temp rises in the house throughout the day over 80* when it is only *85 out side. I have a 2nd tech coming today and I have talked to a couple other people.

I would ask around and see if anyone can suggest another HVAC company. If not I would open up a phone book and start calling different places. See what their diagnostic service calls run. Might just be my location but I know a lot of reputable companies around here have very aggressive deals as they want all the work they can get.

Another idea to find a tech would be to look up local suppliers for the type unit you have. Give them a call and see if- 1. they do service calls and 2. If not they should have a service company they can suggest.
