Maybe it's how you approach the contractor. I had a high efficiency
furnace and a few years later an air conditioner installed and had no
problems getting a requirement into the contract that the installed
product would not cause RFI both times. Maybe I was lucky. I have
written this requirement on sales agreements for large screen TVs and
other appliances with no problems other than "this needs to be approved
by the store manager".

100% agreement here. I have posted this numerous times before and to
everyone contemplating the purchase of potential interference producing
devices WAKE UP and write a REQUIREMENT THAT THE PRODUCT BE RF
INTERFERENCE FREE into the contract. If possible reserve as much of the
payment until after installation and purchase with a credit card in case
of a contract dispute. I even do this for appliances such as
dishwashers etc. at places like Lowes and Home Depot. They sometimes
need the store manager to initial this addendum to the sales agreement
but they have never refused.
In my opinion listening to a similar product is next to worthless as an
acceptance test. The model you listen to might be slightly different
from the one you might get and the installation might be significantly
different from yours.

The bottom line is that I will find an installed system of the same

Good plan, but don't stop there. Get a written guarantee from your
vendor that the system will be free of radio interference, and that he
will remove it and reinstall your old system if there is interference
that he can't fix. Obviously, that's impractical and/or very
expensive, so that will make him do his homework with his supplier(s)
to make sure that what he buys and installs includes all the filtering
and good wiring practices it takes to achieve that.
