[RFI] Comments on RFI from Ductless Air Conditioning Units?

[Larry Benko]

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".
