'15 Genesis V8 with Ultimate Package and '18 Legacy Limited 6 cyl
2021 Kia Soul LX 6-speed stick
Home was built 5 years ago and has a Bryant downdraft single-stage 95.5 efficiency 3.5 ton furnace and blower. Furnace is fully vented, returned and insulated, and apparently is sitting on top of a non-standard empty AC coil box. Furnace is in the garage along the outside wall with a straight shot to both the electrical panel and the location outside where we want to put the AC compressor. All of the bids have been for a 16 SEER 3 ton system.
The 4 bids have literally ranged from $5200 + tax to $8100+ tax, and for the life of me, I can't figure out (1) why this is so expensive, and (2) the explanation behind the spread in cost.
Questions:
(1) The furnace is 5 years old and not especially high end. Is there a benefit here to getting a Bryant/Carrier system vs. say, a Lennox? I've read a lot of mixed bag advice on mismatched systems.
(2) One of the bids suggested that at some point in the future it would be worth installing a multi-stage blower. Is there any point to this if the furnace is only single-stage?
Car related, having the furnace and hot water tank in the garage is why I've lost 3 feet of extra length for parking in my garage...
Well, actually there is. I almost interviewed for a school bus transporter until I found that the pay was only 60 cents more than I'm making now.

point is, I can't help with your technical questions, but can confirm there can be a huge quote variance.

I'm not sure what the problem about Lennox is in the MSM, but mine is well engineered and works with the Honeywell digital thermostat to run for about 30 seconds after heat cycles off to glean all the heat from the system before shutting off the blower.
Backup heating and defrost cycles are hardly perceptible. That wsn't true for the previous two units.
Is Goodman related to the Haier units that came into the US market from China was it several years back. Another neighbor had a shadetree mechanic replace his heat pump and it was a Goodman or Haier. First unit failed early. Replaced by another cheapie. Maybe it's a Goodman now. I should sneak over and see what brand it is.
Edit: Goodman now owned by Daikin, a Japanese company.

I'm kind of thinking installation is what has/causes the most issues.

You said your furnace is "95.5 efficiency 3.5 ton". I'm going to be a little nitpicky here. Furnaces are rated in efficiency and BTU's not tons. A/C is rated in efficiency and tons (just for your info 1 ton of A/C is 12, 000 BTU's).
I had a new Lennox furnace and A/C installed in 2008. I went with Lennox because it was a name brand and it was the best price by at least $1800. Don't ask me why but it was. I got quotes from Carrier, Trane, Goodman, Bryant, and Rheem. I considered all the name brands to be equal in quality for the ones I got quotes for. Although Goodman and Rheem, around here, is considered just a notch below the large name brand guys. I wasn't going to get multiple quotes for each brand because I didn't want to spend all Summer getting quotes.
The Lennox furnace and A/C units I got were the next to the top of the line. The Lennox guy that gave me the quote said he could give me anything thing in the Lennox line up, mix and match if I wanted to do that but felt the second from the top was the best way to go. I questioned him about the top of the line furnace having the variable speed blower vs. the multi 5 speed blower and he didn't think that was worth the price, but again, if I wanted that he'd provide it. Of course the price for the top of the line units was more but he didn't feel it was worth the difference.
As for mixing different brands of furnaces and A/C units, I wouldn't worry one iota about that, it's done all the time. Neither unit knows what the other one is, honest. However, you do need at least a 2 speed blower for heat and A/C. Since cold air is heavier you need a higher speed for A/C and a lower speed for the less dense heated air. That is almost a must. But, if you only have a one speed blower it better be what is considered a high speed blower. I don't know off hand what RPM that is but when you get a multi-speed blower the installer will almost always select a mid-range speed for heat and the very highest speed for A/C and to do that you need a relay to accomplish this. That much I do know but don't worry about this because it is the norm for heating and A/C system.
As you know I can go pretty deep with this, it's almost a bedtime story as it is, so if you want more specific info let me know.
Just remember, mix and match is NO PROBLEM. Just get a reputable brand and installer.

I just had a Coleman (York) HE system installed when I did the remodel. I really wanted Lennox as that is what I had and was a stellar set. The system was 24 years old and never missed a beat. It wasn’t dead, just not big enough with the new addition.
So far the Coleman has worked great too and even though my house grew by almost 600 sq ft my bills were slightly lower running the bigger unit.
The reason I went with the Coleman was the GC gets stellar pricing from “his guy” and the system and all the new ductwork to the addition was only $5400. If I went with a Lennox from a dealer he didn’t deal with it would have been closer to 9k.

More details will follow eventually, I only have the rental for 30 days, until the 28th then it's on my dime. I am not a happy camper right now and it's unfortunate because getting a new vehicle should be something fun. We are so far from fun right now though!!

The furnace is 42,000 BTUs supported by a single stage 3.5 ton blower. The installer I’m leaning towards, who only does Lennox, suggested a multi stage blower but also pointed out that given the climate it isn’t crucial.
The Lennox bid is coming in fairly middle of the road in terms of price but is also the best unit at 18 SEER efficiency. The cheapest is a 16 SEER Carrier unit. I also recognize there is additional cost simply by going with Lennox.
The other middle of the road bid is a 16 SEER 3 ton system from Bryant. Basically the same as the carrier just with the Bryant nameplate.
I know a substantial part of the cost here is simply living in Seattle. But man. Crazy prices across the board.

Local dealer is showing $750 off MSRP before you even walk into the showroom. Those trying to foist ADMs need to go into rehab!
The quality of the fabrication and installation is at least as important as the unit.
I'd see if you have any Goodman dealers in your area and at least get a quote from them.
Mixing-matching brands really doesn't matter. They all function more or less the same and are similar in the way they are manufactured.

A dealer south of here has a dozen in stock, this one had the 10K ADM on their GT2 models (pushing the price north of 60K). A red GT2, which I believe was part of the initial inventory with a 10K ADM, now has a ~$2400 discount. Someone didn't play their cards right.
Wow! I guess that is why you don't see too many mini split systems around.
