offer
IdealHumidity in an 80% AFUE gas furnace. You get all the benefits of
a ComfortHeat Technology furnace: reduced drafts, reduced sound
levels, longer, more gentle cycles, less temperature swings between
cycles, and less temperature differences between rooms. With the
variable speed blower motor, homeowners can now economically run
constant fan to help eliminate temperature differences throughout the
house and to get better indoor air quality. This IdealHumidity furnace also
increases comfort in the summer by wringing out extra humidity when
needed. The 58CVA furnaces are approved for use with natural or
propane gas, and the 58CVX is approved for use in low Nox Air Quality
Management Districts.
