Actually, installation uses new parts that are already checked before
put in the warehouse. All I had to do was rough-in the installation,
everything besides the thermostat and exhaust/intake covers that had
to wait till the drywall and painting was done. In a new home the
system never even got turned on before I was off to another job site.
Basically it seems you don't know about roughing-in a new installation
any more than I did about repair costs.
Why I paid close to $250 last time was that it was the middle of
summer, I had to work and didn't have a holiday off to check anything,
and didn't realize it was going to cost close to $250 for a $13
capacitor until I was handed the bill. Obviously in retrospect if I
had known what the bill would be beforehand I would have done it
myself, like I chose to this time based on that bill and the entire
topic we're discussing.

Here's another hint. That's not always true, I started with nothing
but prior construction experience then the finishing crew that
installed the thermostat and checked the system function later were
more experienced. I proved capable of the installations, was very
rarely called back to any site to correct anything. Usually being
called back meant that the plumber wasn't on-site when he should have
been and I was doing duct runs having to guess where he'd put pipes
instead of it being done already or being able to talk to him about
his plans first.
Come to think of it, I didn't do a poll or anything but I don't recall
any of the guys doing rough-ins having master tech certification and
this was a fairly good sized shop that was one of the preferred HVAC
installers for some of the most popular home builders in the area.
We'd go down the street from one house to the next in new
neighborhoods behind built which got somewhat boring when every other
house was essentially the same except for the shape of the roof.
