I hope I can ask this question about the quality difference between products. Which is the better product in your humble opinions. American Standard 2.5 ton 14 SEER A/C R-22 with a 3 ton VS 2 Stage gas furnace 80% AFUE rating, or a Bryant 14 SEER Puron AC unit with a 2 Stage 80%VS gas furnace. Installer has good references. There is no problem with the price. Thanks for any input you have.
