• The tax credits that were previously effective for 2009, have been extended to 2010 as well.
• The tax credit has been raised from 10% to 30%.
• The tax credits that were for a specific dollar amount (ex $300 for a CAC), have been converted to 30% of the cost.
• The maximum credit has been raised from $500 to $1500 for the two years (2009–2010). However, some improvements such as geothermal heat pumps, solar water heaters, and solar panels are not subject to the $1,500 maximum.
• The $200 cap on windows has been removed.

In order for homeowners to take advantage of this increased tax credit, the windows installed must meet minimum performance criteria:

• “U” Value of less than or equal to 0.30, and
• A Solar Heat Gain Coefficient (SHGC) of less than or equal to 0.30

The consumer should note that not all ENERGY STAR® Certified Products will meet these stringent performance standards. Indeed, most manufacturers currently do not offer products that meet these standards, and will therefore NOT qualify for these tax credits.

Mathews Brothers Company currently manufacturers at least six different model windows that meet or exceed these standards, as certified by and listed in the National Fenestration Rating Council (NFRC) Certified Products Directory.
