    I have to tell ya, I havn't been in the real world of a/c work in awhile. Are they really making coils that tight now that you cant use cleaner on them?

    Pressure washer, without hose, wand or power cord: 75 lbs.

    An additional 200 lbs of hose.

    100 lbs of chemcials

    Multiple RTU's.

    We were not given an official explanation.

    My GUESS (based on another conversation with "unnamed sources near the Pentagon..") is that someone (another company in another region of the country) left coil cleaner on the coils and it burnt off the fins at one of their locations, so their irresponsible reaction is ban the use of the cleaner.

    The EPA is mandating the conversion to new refrigerants... which is leading to new coil designs... that can't take coil cleaning...and so we go skipping along to Gomorrah....

    Havn't really worked on much 410a if that's what you are referring to new refrigerant. Is that ANY 410a coil?

    No, I believe it is a new all-aluminum coil being rolled out now.

    I figure with copper prices rising, everyone will want to go this route to cut initial build costs.

    Okay thanks. I guess I will run into a lot of unfamiliar stuff when I get started back. Wish sometimes they would just leave stuff alone!

    99 percent of the stuff I work on now is under a maintenance contract and coils get cleaned at least 3 times a year. I can understand why you would have to use coil cleaner on poorly maintained equipment, but luckily for the most part I do not need too.

    Amen about the micro channel comment referring to engineers looking at paper and not reality
    don't know why aluminum is being used is it cost or formiciary ( ant tunnel) corrosion
    Trane went Aluminumbecause of it

    Actually it was probably some tree hugger in California that saw foam running down the back alley to the Drain. Called the EPA police because a South Pacific Red Tailed minnow was seen floating belly up in the retention pond. Its Just a matter of time and we will need to have a Hazmat crew alongside you to contain any residuals and Contaminated water during a Coil cleaning. CONTAINMENT & Documented Disposal will be the norm..

    There's an auto manufacturing plant I know of that will not allow anything to enter the storm drains except rain water. They will not even allow city water in them! I mean I asked and they won't even allow a garden hose to run directly into a drain! Absolute idiocy! They have multiple air-cooled chillers of about 200-400 tons, some on the ground in grassy areas, and some on roof tops. And numerous condensing units. I don't know how they, or their contractors, clean these coils. Or if they ever get cleaned. I have friends who do work there. I don't ask, to maintain "culpable deniability". (Or don't ask, don't tell).

    It started with the Eco Terrorist group "Earth First." They used to hug trees for media avails, and then they would come back and drive spikes into the trees in order to injure lumberjacks and ruin their tools.
