During this time the annual fuel utilization efficiency rating, also known as an AFUE rating was developed to classify the fuel efficiency of furnace combustion systems. Currently, the minimum HVAC Efficiency rating standard is set at 78. In 2013 the rating for all furnace systems in the northern states segmented by the DOE was supposed to be raised to an AFUE rating of 90.

A furnace with an AFUE rating of 90 is rated as wasting only 10 percent of the fuel it requires to operate. This is rather impressive, and beneficial to homeowners as well as the environment. However, there are several drawbacks to this new rating standard. The only furnace that has this impressive rating is the condensing furnace. Beyond the initial cost of new equipment, many homeowners face other challenges when installing this efficient furnace.

The venting system often needs to be changed and other implements must be made to successfully retrofit this system into a home. The additional cost burdens are what caused many professionals in the HVAC industry to press the courts to hold off on enforcing the efficiency standards to be raised. Currently, the enforcement is put on hold and the court system is trying to determine the right move to make.

Homeowners that want to get their home up to date with a fuel efficient furnace can take the opportunity to do so before the standard efficiency ratings are actually enforced. In fact, for some homeowners, getting their system updated is a priority. It never hurts to be a step ahead when possible, and considering the benefits of a more efficient furnace, acting now can boost the return of the initial investment. Homeowners are urged to contact a local HVAC contractor to learn more about the latest news and developments pertaining to fuel efficient HVAC equipment and new efficiency standards.
