reduces noise
Every air conditioner or heat pump needs an indoor unit to blow
conditioned air through the home, and there are several to choose from.
Typical air handlers simply circulate heated or cooled air through the
air duct system. The CBX40UHV does this plus so much more.
THE QUIETEST AND MOST EFFICIENT AIR HANDLER
YOU CAN BUY.*
In heating mode, the CBX40UHV increases airflow slowly, virtually eliminating
the “cold blow” common with some air handlers. Low-speed operation helps
keep sound to a minimum. What’s more, a built-in filtration system helps clean
the air of allergy-aggravating particles. This innovative air handler delivers
comfort that’s efficient, quiet and healthy—everything you expect from Lennox.
Comfortable
Blowing away the competition
The CBX40UHV slowly ramps up,
instead of starting at full speed, to
allow the coil temperature to get
hot before air exits the registers. By
slowly ramping up the motor, the
heat pump and the electric heat
strips can “pre-heat” to avoid a
drafty feeling in the winter.
Healthy
Helping everyone breathe easier
Featuring a factory-installed MERV 16
filtration system, the CBX40UHV
provides more effective filtration for
ideal air quality and comfort. This
extremely compact air handler is
designed with high-efficiency
filtration in mind to provide an
optimum home environment.

10-year limited warranty
