You never know, you could even qualify for a utility rebate and/or state tax incentives as well. Not only is this good for the environment and your tax bill, but it should save on your utility bill as well. A Win-Win-Win proposition :o)
So how does it work, you ask? If you purchase and install specific products, such as energy-efficient windows, doors, insulation, roofs and heating and air conditioning equipment, in your existing home, you can receive a tax credit for 30% of the cost, up to $1,500 for improvements you actually "place-in-service". The time frame for the work is 1/1/2009 through 12/31/2010. However, be careful, for some improvements, the credit applies only to the equipment costs.
So if you were fixin to get ready to think about such a project, the time to act is within the next 18 months. You can go to www.energystar.gov for a complete summary of the Energy Efficiency Tax Credits available.
