I am a 3peat customer of this company, since 2006. Needed to replace my old cac unit, didn't do any comparative checks just called convertible heating and ac, because I knew they would have a good price.
Called Sam, who gave me a quote over the phone for an Amana CAC, and had Chris come by to give me the hard copy of the invoice etc., handled the gov't. rebate, agreed to install it when we were ready (because we had other work going on), but agreed to remove old cac prior to installing new unit later (i.e. made 2 trips).
They performed the new install as requested by us a few weeks later, had a mix-up with the coil, called late evening and they replaced it within a day or so (by Dieter, who did a good job), third trip.
It's been a couple of months since they performed the installed (because I thought I had already submitted this review eh...).
I certainly recommend them.
