Re: AN PINK FIBER-GLASS INSULATION GROW MOLD?

[Guest guest]

Barb,

It's fine to use the " fan on " with the AC system. This filters the air

if you have good filtration.

I was only sugggesting a test to provide a worst case scenario for

duct dust. Cycling the blower on and off changes the pressure in the

duct system and disturbs dust. It's OK to cycle the blower, it's just

an electric motor, no compressor like the outdoor unit.

Most central AC systems have safety " time outs " that prevent the

compressor from turning back on too soon after being shut down, but if

the compressor turns on too soon after being on and then off for a

brief period, it can break (due to working against excesive pressure).
