Best Gas Furnace for your homeSize matters!

To conclude, properly sized furnace is the first step when selecting the best gas furnace for your home.

The higher the percentage of furnace AFUE the more heat furnace can convert from the therm of gas. Best Energy Star Gas Furnaces are furnaces which start from 92% AFUE and go up to 98% AFUE. 98% AFUE furnace might cost $1000 more than same brand 90% AFUE furnace but you will recoup that additional cost from saving on your energy bills.

Single or Dual Stage, Furnace Speed Level

High efficiency furnaces come in single or dual stage, they also vary in speed from single to variable.  Speed and stage of the furnace needs to be based on the insulation level of the home, number of floors and size of the duct system. Contractor can easily complete these calculations and provide you with the best gas furnace solution for your home
