We are cooling about 1400 square feet; this half of the house is truly a log cabin just logs stacked for walls and cathedral ceilings throughout. The top is simply Tin->2" white foam-> 2" thick decking as ceiling.
Current unit (dead) is about 25 year old 4 ton 7.4 SEER . Our A/C guy is recommending a 4 ton 14 SEER unit $5000 installed.
A few things I'm thinking about after he left.
1) Smaller unit? before I got in to ECO it ran pretty much constant daytime during the summer, now I've got it down around 50% run time. Does this mean I could get away with 2 tons? 3 tons?
2) Tax credits? Federal tax credits
http://www.energystar.gov/index.cfm?...pr_tax_credits Does anyone know if a standard Central A/c qualifies as a Split system, or a Package system? If it's a split system it would look like I'd be better of looking in to a 16+ SEER unit to get %30 back.
Any and all Ideas / comments / weird thoughts (on topic) are welcome.
