The compressor looks like a single speed, traditional unit. Definitely
not variable speed.
The furnace is a dual speed blower. What I'm unclear on - is this a
traditional dual-speed (no electronics inside) motor winding method to
get dual speed options. Or is it a single-speed motor with some PCM or
similar electronics to give a 50% (or whatever) speed. I will have to
look in the manual to see if there are some hints there.

We are looking at a replacement HVAC and these items are proposed for
the install. I'm paranoid about the RFI noise profile out of modern
HVAC systems and would be interested in any comments.
The Lennox P/N recommended are:
Merit series - ML14XC1$-042 compressor 14 SEER
Elite series - EL280UH090E488 dual-speed (2-stage?) furnace 80%
The installer is aware of the Lennox 604552-01 kit which includes a
differential filter and a snap-on toroid. I've made it clear that
the
single snap-on toroid is likly and that a multi-turn type 31 would be
used in lieu if needed. Which would not have a warranty issue as the
HVAC guy and I share a common electrician who has vouched for the
safety
of this "mod." And we have discussed that similar (multi-turn
toroid)
treatment may be added to the thermostat line as well.
Appreciate any advice on other guys who may have experience with
Lennox
gear in general, or these families in particular.
