My experience was mixed: I was able to get a quick service appointment (next day) and the technician came on time and was a nice, polite guy. Charged me $69 for about half an hour of time, seemed reasonable. On the other hand: the service provided left me with the conviction that I should never call this company again:
The reason for the call was that my central AC stopped working (the outside unit worked but the inside unit (the air handler) in the attic stopped blowing air). Explained it to the technician, he went into the attic and spent about 20 mins there checking things out. Came down and said that the blower motor needed replacement (price quoted: $560). I asked him if he was sure and if it could be some other electrical problem. No, he was sure - it was the motor. Since the system was old (12 yrs) he recommended considering replacing the whole thing (price quoted: $6.5-$8K) instead. He took my email and said I will get an exact quote for the system replacement in an email from his boss. I said I'll think about the options and he left. I looked online for the motor: was on Amazon for $160. Looking inside the blower - seemed like half an hour job to replace it (7 screws and 6 cable shoes total, so the company was asking $400 for the labor, I figured). But reading more online led me to believe that the most likely reason given the symptoms was a failed starting capacitor, not the motor. I took a look at the capacitor (as big as a deck of cards, right in front of my eyes when the cover of the air handler is open) - it was visually bulging on the top. I borrowed a tool from a friend and tested it - it showed an open circuit. I bought a new capacitor from Amazon ($12), replaced it myself (took 5 mins: one screw, two cables total) and the system started working with the same old motor in place.
I'm pretty sure the technician checked the capacitor before recommending replacing the motor - he had removed the rubber cap on top of it which led me to believe that he tested it and it's not something one would overlook given the symptoms anyway.
My conclusion of this service call is that either the technician was incompetent or he knew what the problem was but tried to sell me the more expensive repair (which wouldn't have fixed the problem anyway).
As for the quote for replacing the whole system - it's been three weeks since the service visit and I still haven't received it. Not that I will use this company again, but it's curious that after all of the up-selling they didn't even attempt to close the deal.

Update: got a handwritten letter with an apology from the owner (Wendell) in the mail today and a check refunding the fee I paid. I'm adding another star to the company's rating.
