I might be in a bit of a pickle. Built a brand new house and moved in last November. Told the builder I wanted the Carrier infinity system, and he got with his AC people and then he gave me an "upgrade price" which I agreed to. Several times throughout the project, several red flags went up that these guys were not Carrier guys..First and formost was I told the guy I wanted the Infinity Control, and he didn't know what it was..Oye..
So the system finally got put in and we moved in. Winter things seemed good as did spring. Now hot summer comes along, and that poor thing struggles to get the house cooled off. Basically it runs constantly on high speed, and during the day the temp is set at 80, changing to 76 at 4:30. It gets down to 77 and sits there till after 9:00 pm..Plus the compressor unit seems really loud like it's working too hard (compressor buzzing)
I know if I call these guys they are gonna come out and tell me that it's just fine..So, I called the local carrier dealer. He asked me for the model and serial numbers which I gave him, then he asked me some questions about the house and it's construction. (four ton unit, 110K VS8000 furnace) House 2610 sq foot one story, ten foot ceilings, and nearly 30 windows and house faces west(also tech shield decking, good insulation and Low-e windows). He said without looking at it, it sounds like the unit was too small..He went to researching the unit and found it was sold not here in Austin but in San Antonio TX. He called the guy at the Carrier dist down there and that guy called me..Something really fishy went on..Apparently the company has "branches" but are separate and the place in SA bought it and sold it to the Austin shop. The Carrier guy said he won't sell the Infinity to anyone not Factory trained and apparently the SA branch is and the one up here isn't.(he too asked the same questions and was worried it's too small) Being now my system was ping ponged back and forth nobody know's who's jurisdiction it's in (both guy have been helpful) They both recommended I call a "Factory Authorized Carrier dealer" and after looking at the Carrier site, the one they both recommeneded I called(he is one of the first listed dealers with the Carrier seal)..He is a nice guy, but told me he doesn't use Manual J. He said if the original guys sized it that way than it's most likely gonna be too small to cool properly..He is coming over Friday to evaluate the system, to see if it's wired right and charged right and to see the duct work they put in..
Another problem I am having is all three bedrooms are at least 5-8 degrees hotter during the day, with the thing running constantly on high speed..I am not asking you professional guys for a solution, but of maybe what I should do next? I know I need to call the installing company, but I am trying to get proof there is a problem and I feel this may turn into a fight..I paid nearly five grand to upgrade this dang thing and don't want to have to pay again..So far as I said I have talked to the Carrier distributors in both Austin and San Antonio, and the Factory certified service guy who is coming Friday but I have not yet called Carrier directly..I called the builder and he basically told me I should be calling the installing contractor but due to past experience I want some second opinions...
Thanks for taking the time to read this and I really appriciate any help...
Thanks, John Winn
