design uses an efficient multiple-speed blower to ensure
greater economy and comfort.

The Comforteer series makes service and maintenance
easy, too. So, you not only get economy, efficiency and

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 AFUE1 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.

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!
Example is based on the difference
between a 65% AFUE unit and
an 80% AFUE unit in zone 1.
