My estimate for an AC unit install was for an American Standard to complement my AS furnace. Discussed during the assessment was a 15 seer 2 ton single stage side discharge (going under a deck) unit. (Model 4A7L5024N1 - photo 3). I had received other quotes for the same unit/install and the guy raved about the unit and told me how there is only 10 left in the seattle area bc of the refrigerant update. (The other estimates said the same thing about availability) 

The install happened Friday, and took installers 9 hours and they still have a bit to finish next before the inspections on Tuesday. I was home during the install but didn’t see the unit until the walk around and noticed it was a Goodman (model gxv6ss2410aa) nothing like what was discussed (photos 1-2). I told an installer who called his boss.
While he was on the phone the other installer was kinda honest and basically said yeah these are certainly different units and he said if it was the America standard they prob would’ve been done in 4 hours. 

The other guy got off the phone and said their boss said they “upgraded me at no charge to the better Goodman unit which has variable speed, bc of availability, and threw in a smart thermostat”. No one told me this before the install.

It was Friday at 6pm when they left so they said someone would call me on Monday to sort it out. 

The install guys were great for the record. Worked their butt off for 9 hours with 2 electricians for about 4 hours of it.

I have no brand loyalty - but the AS to AS furnace and quality of AS/trans was such a selling point - so I’m just not sure I got screwed or not?

Should I:

1) request the job is replaced with the AS (assuming it is still available)
2) request a maintenance package to use over the coming years? 
3) request a project discount? (Note the project was 10.5k which was the cheapest of 3 estimates in seattle)
4) don’t stress and roll with it 

Did I get hosed? Goodman instead of American standard
