HVAC Feedback appreciated -

swifter is right, but NONE are "what they used to be" I would NOT put in another condensing furnace (90%+) as ALL of them have higher maintenance issues. I'd put in an "80%+" which is NOT "condensing." Most of those are much simpler and have less maintenance issues

I used to maintain residential/ light commercial HVAC/R. I used to think Carrier and Lennox "were it" Lennox lost a LOT of points for me over the pulse furnace debacle (in the way they handled the problem)

Ruud/ Rheem is not a top of the line brand, and so far as I'm concerned, neither is Crane or Trane (American Standard).

Carrier and some of it's offspring:

ONE BIG THING is to find a company who SUPPORTS and MAINTAINS their equipment. I used to be proud of the fact that as much as 90% of the time I could repair a furnace "on the spot" without having to order parts. This has become complicated as more and more appliances use proprietary parts, draft inducer blowers, specialised control boards, etc.

But AT LEAST they should be able to support what they sell and install, and by that I don't mean "ordering parts" while you get cold, or hot, as the case may be
