HVAC Feedback appreciated -

I am a hvca tech for over 20 years this is a good price hes not making a lot on this install,That being said depending on what units you get will determine how quiet it is. 95 % is good start.and 13 seer if sized right and set up will work fine.

Ok Fellas, Last winter, I discovered that the heat exchange in my Lenox furnace is cracked.....

So my wife's close friend's husband is supposed to give us a deal. He's a good dude, I've hung out with him a few times.
The guy does HVAC for a living and said he'll give me a good price on a furnace and AC. Here's one option:

Trane
95% Efficient Furnace
13 Seer
R-410A Refrigerant
2.5 Ton Condensing unit (A/C)

Installation includes wiring, ductwork, misc. parts.
Warranty
Lifetime heat exchanger
5 year parts
1 year labor

$4,650 Total. What do you guys think?
