I'm curious about the Return on Investment (ROI) of heating and cooling systems. Many of the DIY shows say that you can expect a certain percentage return on your investment from remodeling your kitchen or bathroom. For example, I think I've seen numbers above 75% for a remodeled kitchen. So if you spent $10,000 on a kitchen remodel you might expect to get $7500 back.
Has anyone seen any numbers or statistics for ROI on HVAC. For example, you decide to sell your home and one of the selling points is the new energy efficient heating and cooling system. Or do you guys think people really don't pay much attention to the HVAC systems in the home on resale? Do they just expect it to be working and that's it. I would think people might ask for a sample of what the energy bill might be.
