a swishing or gurgling noise may
be heard.At first 2-3 minutes after
unit start, this noise is more noticeable.
(This noise is generated by
refrigerant flowing in the system.)

noise may be heard.This noise is
generated by the casing expanding
or shrinking because of

circulates smells from the interior
air such as the smell of furniture,
paint, cigarettes.
