Actually yes you are.
In a previous post you said that the tech measured 90 amps on the
compressor, and you have a 30 amp breaker....
Whats wrong with this picture??? throwing parts at it because they are cheap
is bullshit... thats what your accusing the folks in the trade of doing, and
then when somebody comes along and says you need an expensive repair, then
you blow them off and continue to screw around with paper clips and bubble
gum. FWIW, $900 for a compressor change is damn cheap..... in fact half the
price of what it is in the real world. A resi compressor that is drawing 90
AMPS is probably toast.... if not, it will be very shortly unless the
problem is corrected.

Maybe you will figure that out once you get over your capacitor fetish.....
and is doesn't matter if you put one in today, and the compressor gets
replace tomorrow... it *STILL* gets a new capacitor and a filter drier so it
hasn't saved you a dime....it actually cost you more money for the capacitor
that you put in.
Heres a news flash for you sport.... the new compressor may or may not even
use the same value of capacitor as the old one.

There is nothing wrong with a motor to draw 3x its rated amperate at
startup. That should not last very long and the breaker should not
trip if such startup current is brief. Most breakers are designed to
handle motor loads.

As motors go, 3x running current at startup is relatively mild.

My homemade phase converter's first idler motor draws 120 amps at
startup, it is rated at 10 HP.

All true.... but thats not what he said.
I'm still waiting on the make/model/serial number of the unit.

The main problem is that alt.hvac is just a social club for pathetic,
paranoid union types to get their jollies attacking anyone who asks a
question. The fact that their "profession" is heavily infested with the
incompetent, barely competent and outright crooks should be what they're
attacking if they were truly the competent ones, but they're too stupid
to realize that they are their own worst enemy.

hhp436akc1

no brownouts..had the asshole who installed show up at my house without
first returning my message and say "yup breaker switch is
thrown...nothing else".

Soyou can see between that and the $950 estimat I am not real eager to
try a third " professional"
