I had issues with a newly installed Lennox 4 ton AC unit. I made several
screenshots from my 7600 showing the RFI during operation. It was pretty
bad. I called the installer and they sent someone out to check that
everything with the install was solid. It was then they escalated it to
Lennox. Lennox sent an engineer out to take a look and he brought some
filters along with him too. Here's the before and after videos:

They had a complaint from another ham in GA with the same problem so they
already knew what to do. Lennox didn't charge me either. Very impressed
with post installation support.

You've lost sight of the way people in business to make money by
minimizing expenses (time being one of them), and have utterly no
knowledge of shortwave radio see this. To executives in this
industry and contractors, shortwave radio people appear to be just a
handful of goofy old kooks. "Why aren't you on the internet?" they
think. They're not going to blow a lot of time and money on some nut
job when they can do easy no hassle installs everywhere else. If 70%
of prospects had your concerns they'd adapt but there's no incentive
in reality, because hams are simply not that numerous. If I were in
the business and I had to make a business decision about how to direct
my assets for the most profit I'd blow you off too. If I were a
prospect, I'd try explaining to the contractor what ham radio is and
why we enjoy it, and that it is important to us, and explain what RFI
is, and that it has to be eliminated, where it comes from and how to
get rid of it. If the contractor glazes over or seems dismissive I'd
move on. Clauses in contracts to legally force our will are just a
huge turnoff to a person in business. If I couldn't get anyone who
takes radio seriously I'd blow the whole thing off as being too much
of a hassle with not enough ROI.
