AC & Furnace - Trane Var. speed vs. Carrier non
Thank you in advance. I've read and appreciated the thorough responses, but am still confused with all of the numbers.
In Atlanta / one-story / 1,800 sq ft / furnace in attic / easy installation / both quotes from reputable contractors / Quotes nearly identical without upgrades, and at top of my budget (taking rebates/tax credits into account) but can finance if some upgrades worth it.
CARRIER - 4 ton Comfort 16 Two Stage, non-variable furnace, under 75 db
VERSES SIMILAR $ QUOTE FOR...
TRANE XR13, R410a, 4 ton, as low as 75db
with 5 ton furnace XV80 (told the 4 ton is the same price, so 5 ton included "for free")
*Is there a significant difference between Trane and Carrier parts/engineering?
*Is a variable speed worth a $1000 difference?
* Is a 5 ton furnace with a 4 ton compressor problematic?
*Which is quieter? Is there a way to test my current system's db, which I know is too loud?
*Is there another suggested brand within range of these systems?
*Who are you guys answering these questions? :)
