Just moved down to the philly area, and am inquiring about a new HVAC system for my dad's place.
two story townhouse,
gas heat, a/c/
presently there is a York system, about 18 years old. I wonder what the efficiency rating would be?
Also is it cost effective for me to get the more efficient 96% rather than the 80%. I plan to get the variable speed fan. I am looking at the Carrier systems.....any input is appreciated.
Thanks......please ask for any more necessary info.
