[RFI] Multi-Stage High Efficiency Air Conditioner Units

[Rob Atkinson]

First, there's nothing wrong with American Standard as far as I know,
which is a premium brand manufactured in Texas by Ingersol Rand.

Forced air A/C in the home, almost always uses the same air blower
motor that's used by the furnace.  If that's the variable speed
component, you can solve everything by getting an AC motor.  The
variable DC motors are used by people who obsess over a relatively
minor improvement in efficiency.

Why do hams mindlessly use ferrite on everything, including lines that
only have DC on them?  What happened to RF chokes and bypass
capacitors, which when the correct component values and specifications
are used (value, current handling and voltage rating), will work
better and cost much less?
