hello:
as you may have seen by my posts...
I'm faced with all these choices - now that I'm replacing the HVAC in my "fixer-upper"
I plan to sell the house in a couple of years.

It seems to cost about $1000 more to go from 10 to 13 SEER
and if I go with the lesser cost option... I'm wondering if the state of Delaware or New Castle County will cause problems when I get ready to sell the house assuming the buyers don't care.

also is 90% AFUE for gas furnaces expected to be part of the code everywhere in Delaware and the rest of MidAtlantic - since it seems like its part of the code in the colder parts of the NorthEast already.

also would it be a good idea to wait until next year to replace the A/C and do just the furnace now - in the hope that when 13 SEER becomes the standard that the supply and demand equation will be more favorable towards the price...
i.e the lowest the line of most major companies will be selling these and therefore the competition among the various low end brands will be on price (at the 13 SEER level - rather than at the 10 SEER level) to target the "price sensitive" customer.

Thanks in advance yall!
this is an awesome site...
only wish I had found it sooner...

btw: any good referrals for installers in Delaware?
