    @8:25 When I do preventive maintenance, I like to tape those filters together with regular duct tape. It's a lot easier to remove them, especially when it comes to those 250 ton AAONs with 5×2 filter rows. I also find that, after giving a first round of machines' evap coils a wash until they're good as new, taping filters together prevents that line of gunk that's apparent on a lot of equipment. Great video regardless!!

    Looking at this 1" P trap I ask myself – what is the max. negative pressure which can be expected (worst condition) in a case like this? Was it ok?

    Excellent maintenance video. I am at work, attempting to write a Check List for HVAC Air Handlers, and this video has almost written it for me. (I have no background in maintenance, whatsoever). Great!
