AET recommends that our clients have their HVAC units serviced annually in accordance with ASHRAE recommended maintenance prior to the start of the summer cooling season. Note: FREON release in close proximity to an open flame may result in formation of phosgene gas.
It doesn't seem to be a big problem bro. We've been here for awhile. To the best of my recollection .... i've never heard of anyone being harmed this way. The few that have been doing sealed units don't seem to stay with it for a long time. It's quite a bit of work for not much gain. Especially now that so many of the motors are wound with aluminum and not copper. Some jobs just aren't worth doing. There's probably more money in making youtube videos telling people how to scrap than actually doing the work itself.
