New System Quote
I just got a quote to replace my heat pump system. I'm happy with the sales person; he did a manual load calculation and came up with around 44,0000 BTU/H (builder put in a 3.5 ton). He measured lineset, ductwork, etc. as well. Question: can a 7/8" suction line be used with a 4 ton unit? It's going to have to be used... He wants to put in a 4 ton regardless of whether we go with a dual stage or not (our home sq. footage is about 3500 he said) and we have over 30 registers. I was quoted 3 systems, the Bryant Evolution 16, the Trane XL15i, and the Trane XL16i. The prices are very, very comparable and all systems have a rebate. The Trane units would go with a 4TEE3F40 air handler (we can't really fit a *49 air handler in the basement). However, I just realized that the 4 ton XL15i and the 4TEE3F40 isn't an ARI-rated match, so I won't choose this option (unless he planned on fitting the *49 for this setup somehow). He talked about wiring issues with the Trane dual stage system; a new wire would have to be run. He wasn't pushy in either direction, which I like.
The quote includes:
-Bryant 4 Ton Evolution 16, Trane XL15i, or Trane 4 Ton XL16i
-Bryant FE4 air handler or Trane 4TEE air handler
-Evolution control or Trane TCONT803
-flushed lineset (new one would be very difficult)
-new pad, 3" pumps, disconnect, wiring, sheetmetal, etc.
-10 years parts/2 years labor warranty (extended available for extra)
Options (I think I'll go with both):
-F100 media air cleaner
-AprilAire (if we went with Evolution it would be Bryant's made by AprilAire) large bypass whole-house humidifier
So, any thoughts on which system to go with (XL16i or Evolution 16)? The ARI figures aren't terrible for both except for heating on the Trane of course (not even 3.5 tons with the *40 air handler - just over 3.5 tons with the *49 air handler).
Since all quotes are from the same company I would choose the Bryant unit.
My personal/professional estimation is the Bryant is better quality equipment and with the 2.5 ECM and the Evolution control superior comfort.
Might have the 3.0 version by now.

The Bryant with Evolution control.
Any issues with using the original lineset which had a 7/8" suction line? Thanks.
I would replace all that is accessible especially horizontal sections. Other than that as long as they flow Nitrogen when brazing the copper purge with Nitrogen triple evacuate to three hundred micron and install a proper liquid line drier. These procedures shold be followed even if they replaced the refrigerant copper.
What if you got there and he says Im ryan hughes .Would you leave?
post a picture on here and he has his red marker out ready to point out any flaw

You need to verify that your lineset is sized correctly for a 4 ton. Can't help you here.
I personally would recommend that the lineset be changed out-both from the size issue and the new type refrigerant.
I like Trane HPs better but depending on system configuration, they can be light in BTUs both in cooling and heating. If price is not an issue, then go with the Bryant Evolution system. The Evolution controller seals the deal.
Ryan the line size is fine, the 049 is 5-1/2 taller. I would go with the 4TWX5048 if he can fit the 049.
The ductwork was looked at and he determined it can handle a 4-ton unit (1 reverse L branch 16x8 and 1 rectangular branch 20x8 off the supply plenum - hope I got those numbers right).

I'm still considering it, but he said he's had no issues with flushing the lineset with RX-11 and pulling a vacuum. I asked them if they used nitrogen when brazing and was happy to hear that they did.
As far as the costs go, the XL15i, XL16i, and Evolution 16 are all very close to each other due to rebates.
I'd like to confirm that the *49 will fit, because if I go with Trane I can't see putting either unit on the *40.
Any reason why you recommend the XL15i second opinion? Is the dual stage in MD not worth it? At this point I was only considering the dual stage units. Don't know the electric rate but I know the electric bills are very high.
Thanks for the help.
Just did some quick measuring. The Lennox right now is roughly the height of the Trane 4TEE3F40. To go with the 4TEE3F49, that would be, as second opinion said, an extra 5-1/2 inches or so. Right now I have a 19" high return base plenum. The *49 would put me at around 12-13". What do you guys think? 3 returns... Too small return plenum? Going up isn't really an option; the supply plenum is already a bit small. I'll post some pictures.
Supply Plenum (around 19" high and branches off at around 10.5" high):
Bonus (boxer puppy ):
Sounds like you have a really good company I would use the the bryant
