I agree.
Actually Goodman joined with Amana about 10 yrs ago and Amana has always had high quality old school Maytag quality ACs.
The tier 3 line of Goodmans were Amana clones and just as good as the tier 3 Trane/Lennox units.
Goodman was very clever and got into the builders grade units when there was the housing boom 20 yrs ago and had taken over Janitrol which became known as Junkitrol.
They have since eliminated the crappy builders grade quality. There are cheaper units made by Nordyne which you find in mobile homes etc and there is a market for very basic cheaper somewhat noisy units due to pricing.
Point is Goodman is a company with 3 tiers of quality same as Lennox and others.
I would not be afraid to buy their unit. Daikin is a HUGE huge company in Asia like Siemens is in Germany/Europe and makes high quality units.
Point is like Amana the quality transfers when they take over another company and I am sure Goodman has gone up with that takeover also.
