Have decided to go with Trane to replace my current furnace and air conditioner. I am in a 1700 sq. ft. home in near Philadelphia, PA. Was quoted:
XV80 TUD100R9V3K 2 stage 80% variable-speed furnace and
XL15i 4TTX5036 3 ton, 15 seer R410A air conditioner.
Was given alternate pricing for XL 80 two-stage standard fan TUD2B100A9362A 100,000 BUT input, 80% and
XR13 TUD2B100A9362A and XR14 (dont know model number TUD series) air conditioners.
Any opinions on this equipment? Is the variable stage really worth the extra money over the two stage standard? The specs show the blower speed on the two-stage to be four speed. Does the variable speed make such a big difference? In addition, do I need a two stage thermostat for these furnaces?
