Thanks to all for the help, particularly acetc. With acetc's help, I checked with Amana distributor, who was quite surprised to have an end consumer calling them. After twisting their arm, they finally referred me to a couple of contractor's.
I chose "
Lindsey's" based on internet reputation, and they sent a technician out. After 5 minutes in the attic, he came down and told me the belt was worn, but it would be very easy for him to find a replacement since an old belt carton with the info he needed was laying right there. He put the old fan belt back on and said he would be back with a new one. He didn't even charge me at this time. And I finally had AC back on.
As you can imagine I was hot under the collar, pun intended, at the previous HVAC company named "Air-tech" that had tried to cheat me. I immediately got word out to my neighbors not to use this company, since I had seen one of their trucks stopped down the street.
The Lindsey's technician returned after a few days and put the new belt on and charged me $99 including the belt.
I then called Air-tech and demanded a refund of the $119 I paid them for their service visit. After talking to a couple of their people I was promised a refund. A few weeks later, still with no refund, I get an estimate in the mail from them for $7,281! Incredible!! Well after bugging them with several more phone calls over the past 2 months, I finally got a refund this week.
So I hope this helps someone else out there. Big thanks for everyone's advice, since it may have saved me a ton of money.
