Nothing wrong with Goodman except the stigma from the old days when they were painted turd brown. Problem is they sell to anyone,so there are alot of fly-by-night installers putting them in. I have a 12 year old (turd brown) Goodman heatpump that has been trouble free. I also have a Green Goodman heatpump, 4 years trouble free. I also have a 2 year old Trane heatpump that has the EXACT same compressor as my newer Goodman. My Trane also has a Chinese rev/valve and fan motors like the Goodman.
5 or 6 years ago, I got an estimate to get a 5T AC unit installed in my existing (gas) furnace system. The bids went from $4000-$7000. All to install a compressor, run a 36ft line-set and connect to an existing evaporator already installed under my furnace and connect to an already present 240VAC connection. All the installers said they could install it in one day.
All the heating and AC units use the essentially same parts. The big difference is the name on the outside!
The
problem you mention about Goodman(they sell to anyone),
is the best feature . I bought mine on EBAY, they shipped it directly to my door on a pallet, I paid no sales tax and received it in about a week.
The compressor was precharged with R22. All I had to do was connect it all up, silversolder it together, suck it down and turn it on! (I did purge it with Argon though before I connected my vacuum pump) I didn't have to add additional refrigerant.
I paid about $1700 for the entire unit and another $250 or so for the copper tubing line-set, electrical box, etc......... Since I already had power at the compressor site, I only had to put a disconnect box on the wall.
In 1991, I replaced an electric furnace at my previous house (belongs to my Mo'inlaw now) with a 60k BTU Goodman +90 gas furnace. Other than having to replace the hot surface igniter a couple of times in the last 25 years, it still works flawlessly today!
There is NOTHING wrong with Goodman HVAC equipment.
For what it would have cost me to have some HVAC "professional" install a "name brand" furnace back in 91, I could have replaced that Goodman 4 times in those last 25 years!
My next furnace will be a Goodman.
