Personalized Air Conditioning

I just had a New A/​C unit replaced today! I had called around the area for quotes. The Gentleman that arrived to quote the replacement/​install was quite professional. I went with this company because a neighbor here in Palm Aire had used them before with success. They were my middle bid.
This morning, The Install team arrived 15 minutes before schedule so I was quite hopeful. Other than the fact that the Install «BOSS» as he called himself REPEATEDLY. Shouted instead of speaking. things were moving along well until his selection of thermostat replacement wasn’t nearly the size of the one I had .When I asked for them to use one the correct size. I was literally shouted down! After a 20 minute diatribe on how I HAD to use this new, better… blah blah blah Thermostat. I gave up. When he suddenly arrived after having been on the roof. he said he was done and expected payment. The air handler and the air return were not in any way connected! The air being circulated was being pulled both from the air return AND the entire space in between my unit on the 2^nd floor. and the open 21 inch space to the 3^rd floor. When I brought the unfinished business to the attention of the «BOSS» He went NUTS! Ranted and raved that it had to be that way. after Craig the gentleman that gave the quote. specifically mentioned that the space needed the duct work «holes patched» between the air handler and the air return. The installation «BOSS» said «I’ve had enough from you» and stormed out of my condo. While my call to the company was quickly answered after the incident and I was smothered with apologies for their «hothead, likes his own way» (their words) Installation «Boss». I don’t hold out much hope for anything more than excuses when they send the initial Quote employee back to go over the situation. Given that the expectation when one is paying thousands of dollars for a very important appliance is NOT being shouted at and having the installation Boss through a fit and storm out. I think it best for anyone in need of a New A/​C to avoid this company completely!
