Many consumers don't realize that efficiency ratings on gas furnace labels fail to consider a critical factor in overall AFUE ratings; which are designed to help consumers compare furnace brands.  The rating are based on natural gas consumption.  When electrical operating costs are added, the overall efficiency picture can change dramatically. 
Bryant's model 355 MAV Plus 90i furnaces are designed to minimize both natural gas and electricity use, for the greatest total energy savings.  When gas and electrical efficiency are combined, the Plus 90i offers the lowest overall energy consumption in most applications.
Based on the latest DOE and GAMA information, Bryant's Plus 90i offers the greatest energy savings in the most GAMA categories.  Bryant's Plus 90i furnaces use two-stage heating and variable-speed fan technology to reduce energy use.  The patented intelligent control continuously maintains the highest level of comfort, yet at the same time ensures maximum time in the efficient, low-heat mode.  When you combine the advanced control system with better combustion and a super efficient ECM blower motor, it's easy to see why the Plus 90i achieves a high AFUE rating with very low electrical consumption.
The Plus 90i offers you the customer three distinct advantages, for one it can offer you the best overall energy savings on the market in a time when energy prices are going thru the roof.  But that's not all.  Along with the energy savings, customers get the quietest unit on the market and a level of comfort that's unsurpassed by anyone.
