I am purchasing a new 3000 sf house in the DC area and the builder has given us an option to upgrade the HVAC system.
The upgrade is an upgrade from a 10 seer to 12 seer a/c system and from a 80% to a 90% furnace (all Janitrol). also with the upgrade they increase the R rating from R-15 to R-18 in the walls, and from R-30 to R-38 in the attic (i think).
What do they want for this "money saving" upgrade?.....$4200.00 !! Plug that into the 30 year loan and with intrest.... WOW thats a lot of money. Will it pay for itself over the life of the system?
Any advise?? is it worth it? or is it just way too much??
