Had a Goodman installed Sept 2021. It replaced a 12 year old, 15 seer Luxaire. I read all the reviews on their website (yeah what a laugh) This was supposed to be a 2 stage, efficient system. The truth... It is highly INEFFICIENT. This past month it used over 900 kwH more than the 12 year old Luxaire and the average temps were the same. Tried contacting Goodman directly because our HVAC contractor is so busy (and he is not a Goodman dealer specifically) for a Distributor name or someone who truly knows how to set this up and all I get is form letter responses. Why bother having a contact page when they don't give you any useful information. I never thought I'd say this but I miss the Luxaire. I am so NOT impressed with Goodman. And... it wasn't all that cheap either!
