AFUE: The federal government has established Annual Fuel Utilization Efficiency (AFUE) ratings to allow you to
compare the efficiency of furnaces. The higher the AFUE percentage is (e.g. 95%), the more efficient the furnace.

Example:
$1,596 – $1,297 = $299
(Your estimated annual savings)
That’s a 20% savings!

Savings you can see
Advanced Comforteer gas furnaces
are far more efficient compared to
many older units. Factor in higher
reliability and reduced service
costs, and a Comforteer purchase
pays for itself fast.
To use the map and chart:
First, determine the AFUE
1
of your current
system. Then using the map, find your
zone. Cross-reference your zone and
AFUE in the table to determine your
approximate operating cost. Take the
difference between your current cost and
that of a new, more efficient system to
learn your estimated annual savings.
