really just a pretty rude guy!
No. I think there is more to it than "he knows what he is talking about". I think he is just one of those folks who is determined to be right, have his way and is not very imaginative. Someone who has been in the business a longer time would probably try to figure something out that would please the homeowner, ie, the one paying his bill. Instead, he just yells that if we "go against his wishes, we will be sorry"...doesnt sound very business-like to me. He has made no effort to find another way to do this...its "his way or the highway"...frankly, I don't know if he has even been out there...just sends the lackeys.
So called "pro" not so professional
The so called pro did not honor his contract from the beginning...he and the building contractor told us on more than one occasion that prior to beginning the installation of AC, he would meet us at the site, do a walk through and go over everything with us. He did not do that. We went out to look around one day, and work was almost finished. Never had been notified of said walkthrough. Just one of those professional things he did.
