I moved into a new community and the builder's grade was Goodman which came with a standard 5 year warranty, parts only. I paid extra monies ($700) for a Trane Upgrade, but was allowed to only after I presented ample data to the builder that said Goodman was actually "not so" Goodman.
Trane comes with standard 1 year warranty. The HVAC installer told me it was a steal to have all 3 of my zones, upgraded to Trane for only $700. The biggest reason why Goodman has decent ratings is because of their 5 year warranty. The way their units are designed, the parts and subassemblies break down often, but since the cheap parts are covered, homeowners only pay labor. With Trane, they are built to last. Do a google search on these two brands. The choice is yours.
