Installation is half of manufacturing. The best equipment installed poorly is garbage, will under perform and can damage your home. American Standard = Trane. Goodman makes decent quality equipment with some of the longest factory warranties in the business.
I'd be interested in knowing why a competitors proposal had more value than mine.
“I am for doing good to the poor, but...I think the best way of doing good to the poor, is not making them easy in poverty, but leading or driving them out of it. I observed...that the more public provisions were made for the poor, the less they provided for themselves, and of course became poorer. And, on the contrary, the less was done for them, the more they did for themselves, and became richer.”
― Benjamin Franklin
