My Trane makes a lot of noise. I added their "fix" but I think I
probably need to make sure it's properly grounded.
The bigger problem is that my furnace is a hybrid, meaning that when it
gets too cold for the heat pump it uses gas. Unfortunately the igniter
for the gas is really RF noisy. I haven't looked into that at all.

For those who have not yet had to replace your HVAC systems, I recently had
two American Standard heat pumps installed at my house and I have not
detected even a hint of RFI. Both units have variable speed blowers and the
larger one has a variable speed compressor and a network thermostat. I was
listening on multiple receivers when they powered the systems on and I heard
nothing on HF and VHF.

Hi,
Has anyone had experience with RF interference from their Lennox furnace
(model and age) and what their solution was??
Gotta love these newer furnaces that are micro-controller based, variable
blower(s) speed with network based thermostat control.
Please contact me off list.
Thanks,
