Purchased Amana 96%, dealer installed Goodman GMH9570
A few days ago I signed a contract with my local well known dealer to install an Amana 96% furnace. When I got home from work tonight, they had installed a Goodman GMH9570 furnace. The dealer is telling me that the GMH9570 is now certified to be 96% effecient, which I can't find confirmation of anywhere. The yellow efficiency rating sticker on the front of the furnace even says it is 95% effecient.
My concerns - I paid for an Amana 96% furnace - but that's not what I received. I realize Goodman makes the Amana furnaces, but I also realize that the GMH9570 furnace should cost around $1,000 (base furnace not installed) and the Amana 96% furnace should cost around $2,500 (base furnace not installed). I paid $5,800 for the Amana 96%, an Aprilaire whole house automatic humidifier and the Comfortair thermostat (I know the thermostat is about $400).
Had I know he was going to install the Goodman GMH9570 I never would have agreed to pay $5,800 for the system installed.
What are your thoughts? Is it fair for him to swap the Goodman 9570 for the Amana 96% without letting me know?
Aren't there some pretty significant difference between the Goodman 9570 and the Amana 96% like the motor (I think the Amana has the variable speed motor, where the Goodman has a two speed motor). What other differences are there between the two?
I really feel like they are trying to pull a fast one on me. So far, they said they are 'looking into it' and will get back to me.
Please give me your thoughts!
