Hi, I'm remodeling an old Victorian row home -- two stories plus basement, about 2,700 sq. ft. -- in Washington, D.C., and need to install an HVAC system. The options are pretty confusing. (First-time homebuyer here!) This is what one company is proposing after doing a manual J load calculation -- does it seem like a good deal? Any input would be helpful, thanks!
