New energy efficiency guidelines are about to take effect which will have a wide-ranging impact on homeowners, particularly those in Colorado. After May 1, 2013 no furnace can be installed in Colorado with less than a 90 AFUE (Annual Fuel Utilization Efficiency) rating. Naturally the cost of these units is going to be higher than the older, less efficient models. However, to make it more affordable for homeowners to make the switch to the more efficient products, companies like Rheem are offering instant rebates of up to $1,200.00 through December 15, 2012. Other rebates are available through utility companies, local and state agencies as well and could add up to a few hundred additional dollars. Because the average home expends around 60% of its energy usage on heating and cooling, consumers with high efficiency systems will see a return on their investment through energy savings over a few short years. Rebates make the proposition even more attractive for homeowners to replace older, inefficient systems sooner rather than later.
