This is a follow-up to my prior post regarding a tech charging me $$$ to do a "required" Nitrogen leak test before adding Freon. At the end, he says the leak was too small to detect and adds the Freon anyway (probably what he should have done from the get-go).
From what I've gathered on this forum and other reserach, the EPA does not require leaks in systems under 50 lbs to be fixed before recharging. I pointed this out to the HVAC company and they insist that exemption is for commercial units only, and that EPA requires a leak test/repair before adding more than 1 lb of Freon to any home system. Needless to say, I feel like I was ripped off for an unnecessary leak test that wasn't required and in which the tech didn't even find the leak!
I found the web page on the EPA site http://www.epa.gov/ozone/title6/608/leak.html#relief that talks about the 50 lb cut-off for leak repairs. Is there anything from EPA that talks about small residential systems that I can show this HVAC company?
