Nothing means nothing. I went up into the attic yesterday to reroute some
LAN cables from my router to computers in various rooms in my house.
In the process, I handed down to my wife about 25 feet of ducting that was
left from the previous remodel. Dead and discarded ducting that the workers
were simply too lazy to hand down to ground hands for disposal. I used four
rolls of metal sided tape to seal air leaks in the ductwork that the
previous "professionals" were incapable of wrapping around pipes. Yeah,
putting tape on gaps is tough, even for trained professionals. I opened up
and rounded out several areas where they had crushed ductwork by crawling
over it, and not putting it back to at least some form of round.
All this done by hvac "professionals" who were paid top dollar.
This happened before my appearance on the scene, or I would have not paid
them until they had done the job and done it correctly. We get into all
this discussion, but when a sixth grader can look at a pipe and see it has a
big hole in it, there is some indication that there is something obviously
wrong with this picture.
We just serviced a system yesterday and found the air free CO over
800ppm. Went on a no heat call a week ago. Tripped flame roll out.
Air free CO over 2000ppm - couldn't get the meter out quick enough.
99 times out of 100 changing a gas valve is no big deal. You just
have to decide on the chance you want to take. What is scary is there
are a LOT of companies that don't check CO in any case.
Fall seven times, stand up eight
We have two digital CO monitors in our house. So, although we don't have
the portable ones, we would know real quick if we had a problem.
The way the smart valve is put on the pipe nipple, and held to the burner
with only four sheet metal screws, it would be impossible to change any of
the configuration there. Turn gas valve ninety degrees, unplug, unscrew,
put on gas tape, screw new valve back on nipple, put four screws back, turn
gas back on, and you're done.
But I guess I could spend $400 for some needy hvac guy to come out here and
do an hours worth of work, and that would include a couple of cigarette
Makes about as much sense as paying $700 to get your hot water heater
changed. I changed my own for a little over $250, and that was with a new
pan and blanket.
Thanks Cheri - I appreciate your support -- you are a rare
gentleman/gentlewoman(?) among the other baboons here...
I just hope that they are not exemplars of the rest of the profession
-- I assume that the good and helpful ones are gainfully employed and
know not to waste their time here among the HVAC "pro" misfits and

What was wrong with it? and why did it fail?
