I had one call back in apx. 20 years, and the reason that I had that
because of manufacturing screwed up which I windup paying for it
That is also because I did not go by my own instinct but lessoning
to some else big mistake that will not happen again!!!


Sigh. What a load. A 'callback' on some of my jobs would require it
to be scheduled on one of NASA's launches to the ISS. A lot of the work
I've done was mission critical. There was no room for mistakes. Only
when working as a TV tech when I was still in high school were the
standards low enough to see the occasional callback. Of course, tube
TVs needed a lot more maintenance than modern electronics.

So - the supply house carries maybe 10,000 items in stock.
They have maybe another 40,000 or 100,000 they can order. You want
the HVAC guy should carry one of each on his truck ?

A quick check at some random parts site

http://americanhvacparts.com/Merchan...egory_Code=ele

Shows 24 TEV's for just one manufacturer. They are not
interchangeable. They list 29 other manufacturers with TEV's as well.

You figure the HVAC guy should carry 700 TEV's on his truck ? And
that's just one part among hundreds that are common.

Now try doing the work outside, at night, in the rain, or in a
blizzard, or in the blazing sun on a 98 degree humid day. Try having
to go up and down a 32 foot ladder and then walk ~ 1/4 mile across a
white roof in the sun to get to the unit. And back again for each
tool or part you need.

If you happen to need a 50 lb tank of gas, or a 30 lb torch, or a 20
lb vacumn up there - get to humpin' it. Then bring it all down again.

And you better get 4 or 5 calls done, minimum, on a slow day.

TV repairmen are wusses.




There are TXV kits that allow for putting one together on site. A
universal blower and condenser fan motor is available too as are
universal oil filled capacitors. The problem with them is cost,
the universal capacitor that has muli-taps costs $50-$60 wholesale,
where a standard value costs as little as five bucks. As for TV
repairmen being wusses, 35 years ago I managed a TV repair/sales
shop and there was nothing wussy about carrying a 300lb console
TV up a flight of stairs or climbing on a roof to install a 50 foot
mast. giant antenna and rotator. These days, some of the flat screen
TV's I've come across weigh more than a fat woman. Back in the day,
TV repairmen did a lot of climbing and spent time in attics installing
twin lead and coax cable. Of course, when I was involved, CB radio
was a big thing with another set of antennas and cables to run.
