For your convenience, here are some links to the "Energy Star" tax credits you may want to take advantage of if you are remodeling or replacing your system. At Affordable Comfort Heating And Cooling, we suggest homeowners replace their system every 10 years. Your HVAC system is a major investment and consumes nearly half of the energy in your household. Why not save energy and money? Consider these tax credits. Read about the qualifications at http://www.energystar.gov/ or http://www.energysavers.gov/.
