Your understanding parallels mine.

Ralph, you're welcome.

Goodman (R32) option is I believe the best choice going forward at this time in 2025. Primarily due to availability, lower costs, lower parts costs (depending on model chosen) as Goodman makes higher end models just like any other manufacturer. (Other brands using R32 (Daikin / Amana -- same manufacturer).

All other manufactures are using R454b, many of which can not get the refrigerant. Some have said these kinks may not be worked out until later this year sometime. There are no concrete time frames, I can tell you that... these things seem to change day to day.

I haven't heard of the old freon (R410a) coming back. The units available are slim pickings, with very few choices if any after 2025 it becomes illegal to install new R410a equipment. In a few years R410a is likely to be severely hindered from what I am seeing now. People will say I am fear mongering, but with what is happening with R454b?

The other con with R454b is PFAS chemical bans, as PFAS chemicals are used to make it. Europe has largely banned these substances already. If shortages continue maybe some additional manufacturers go back to the drawing board and design and make more R32 equipment available?

To me I think that is the most logical. But it seems the world is set on something else, got duped by a chemical company with patents on the freon they need. (all about the money it seems and nothing else. Buyer beware)

I really hope you are wrong.

Trane may be a slight step up in quality, although the difference may be negligeable (most of these companies use the same component parts). The quality of install far outweighs any differences in equipment quality.

I like Goodman equipment, just make sure whoever installs it knows what they are doing. Personally, I wouldn't worry about getting a system with R410a. You don't need safety interlocks for leaks of newer flammable refrigerants!

When I replaced my heat pump, I chose a two-stage unit which is just great. When temperatures are moderate, the compressor and blower operate at reduced speeds. Longer run times help reduce humidity. The slower blower speed the "wind" from the vents and dramatically reduces the "whoosh" noise from the HVAC system. The Goodman GLZT7C appears to be the least-expensive Goodman two-stage unit (shown on the Goodman website). You do not have to use the fancy-pants Comfort Bridge; it supports a conventional two-stage thermostat. I have the excellent wi-fi Honeywell T10 Pro.

Thank you all, went with the Goodman unit (R32).
