Does the tax incentive apply to other things besides HVAC equipment?

Yes, and this is why it is so important for you to act quickly, because tax credits can be claimed for energy efficiency improvements of all sorts: windows, doors, insulation and sealing, roofing and other improvements. There will be other contractors competing for the business. 9. What documentation do I need? While it would be in your best interests to have manufacturer certification documentation available for the products you install, for it is the HOMEOWNER who needs the paperwork, not the contractor.
