and throughout the home. Using the

exclusive flow-through design, the

secondary heat exchanger reduces the

pressure drop in the furnace which leads

to lower electrical usage, an important

part of this unit’s efficiency. Carrier heat

exchangers are backed by a Limited

Lifetime Warranty. (See Warranties

section for details.)

When we put it all together, the

Comfort™ 92 combines quality and

design to bring high efficiency and

comfort. You will enjoy the versatility

and ease of installation of this unit. The

Comfort™ 92 is equipped for either left-

or right-side connections. Blower speeds

are easily adjustable with speed-taps

conveniently located on the control

center. A combustion inducer allows for

more use of 2-in. vent and combustion-air

piping, keeping installation costs low.

As with other Carrier furnaces, this

model is designed to work as a part of the

total home comfort system which in-

cludes elements for cooling, air cleaning,

humidification, ventilation, and zoning.
