Recently got a foot in with a big managing agent for the servicing and maintenance of centralised extract systems at a local luxury apartment development. Potentially plenty of work, since the systems haven't been touched in the 10 years they've been running. Got called out to one yesterday - landlady says it's totally kaput. A local, established and respected contracting company charged her nearly 400 quid a year ago to fix a part and it's not been right since, making odd noises until finally packing up completely. They want to charge her over a grand now for a complete new unit, saying the problem is unrelated to what they did previously (might be, might not - hard to prove either way).
I dropped the cover off and the problem was immediately evident - the centrifugal fan's bearing had collapsed and the fan had made a bid for freedom, taking some of its housing with it. Not a problem - easy fix with a new blower assembly and considerably cheaper than a new unit.
The tenant then pointed out the fan control unit and said that's what the last lot took away to fix and the system hadn't been right since. We were both curious to see what £400's worth of repair to this module looked like (a brand new one is less than £200 I've since found out) so I popped the cover off to find the only bit of non-factory flow soldering revealed a replacement 1uF cap! I'm in the wrong game. How do these buggers sleep at night!
