80% AFUE At Budget Price
Carrier provides an 80% Annual
Fuel Utilization Efficiency (AFUE)
gas furnace for the budget conscious
consumer and builder. The 58RAV
offers the same high quality you
demand and receive from Carrier.
The cabinet is constructed from a
specially selected galvanized
embossed steel with a clear coating.
This material provides the same
protection from humidity and rust as
our other cabinets.
The 58RAV offers a hot surface
ignition system which provides a
superior and more reliable ignition
than older spark relight systems.
The heat exchangers are constructed
of aluminized steel and covered by a
10-year Limited Warranty. They are
Carrier’s patented Super-S heat
exchangers that improve heat transfer
and enables downsizing of this furnace
to only 40 in. tall.
To improve the sound level, we have
incorporated a soft mount inducer
assembly and a slow opening gas
valve.
The control board is the brain of
this induced-combustion gas furnace.
It offers a unique self-test feature
that checks all the major functions of
the furnace within 1 minute. The
control board also features a 3-amp
fuse that protects the transformer
and control board. Another feature
on the control board is a LED status
indicator light to ensure top furnace
performance.

HUMIDIFIER
By adding moisture to winter-dry air, a Carrier
humidifier can often improve the comfort and
keep furniture, rugs and draperies in better
condition. Moisturizing household air also helps to
retain normal body heat and provides comfort at
lower temperatures.
