Goodman - I’ve read enough of the hvactalk forum to understand that Goodman’s biggest reputation problem is that they’ll sell to anybody with money- handyman, hack or homeowner. It’s the quality of the installation that matters. Remember, they have to bring the pieces of the system to your house and then assemble it and tune it. It’s not like buying a car that was built in a controlled environment and is a finished product. Something else I learned online - all ducts are undersized. And returns are too small. “Costco” - they wouldn’t use the Lennox dealer I wanted to use. It worked out okay in the end with the factory rebate and a healthy discount for paying with a check. We were married in November and were redoing my wife’s 28-year-old home. I decided on a variable speed everything communicating heat pump with a SEER of 20. Why? Because it’s quiet, cold and sucks the humidity out. It’s semi-tropical here, plus we’re near the river. The old American Standard 3.5 ton unit and air handler was loud, clanged, and seemed to have one speed - breezy. I also had them tear the duct work out of the crawl space- it was duct board and flex and really nasty - and put in insulated round steel. Why? It seemed like the thing to do. I hope it lasts 15 years. They don’t make them like they used to. I’ll be pushing 85 by then if I’m around.
