Re: Someone should be ashamed...
WOW, was the wiring like that when you unbuttoned the side panel

I have a recent experience something like that.
We had our AC go on the fritz a couple weeks ago, the day before I was supposed to go on vacation. I'm thinking $300-500 and the first guy quoted $1000-$1300 to clear an obstruction. I felt like I was sitting in a car dealership with all these numbers, lines, columns and odd terms written all over a piece of paper. A quote to replace our 4 ton combo system was $10K, of course they could be over that day to replace the system... I paid him the $29 inspection fee and thanked him for his time. Heck, I'm not dumping $1K into an old system, 10K for a replacement didn't sound right either.
The next morning I crawled up on the roof to see what's up and find several screws sitting on top of the unit (they were not there the last time I replaced a motor) and the the compressors shrader valve caps were sitting on the bottom pan of the unit, nice shiny clean brass fittings were looking at me from where the caps were the day before.

After checking things out I saw the repair was out of my league, so I asked a neighbor if he knew an HVAC guy, he did, which was a good thing. The second HVAC guy put some freon in the system and I could see the outlet duct temps drop as he was adding the freon. Outlet duct temp went from 74* to 61*. His bill was $130 and I tipped him another $100. The AC has been working great for 3 weeks now...
So not only did the first guy misdiagnose the system, he was going to charge 10X what an independent shop did and didn't left things torn apart. Sure happy I found an honest and knowledgeable person to work on our AC system.
Oh, I asked the good HVAC guy what a ballpark figure would be for replacing our combo system, $3500-4000. That's one heck of a lot better than $10K
