funny screwup with a carrier unit that cost me $800 in parts

so im on this service call for a carrier infinity system, guy said it was freezing up on startup. turns out i mixed up the superheat and subcool readings, hooked up the gauges wrong like a total noob. spent $800 on a new txv and evap coil parts before realizing it was just low on r-410a from a slow leak. lesson learned, always double check your manifold setup.

hit 25 calls this month, all mini split installs going smooth as hell.

hate when customers watch you work, always second guessing.

that sounds like my first year, lost a whole afternoon on dumb mistakes.

PE firms buying up all the local shops, killing the small guy.

never trust a diy mini split install, seen too many fires.

same here, gauges saved my ass more than once.

ugh, back killing me from crawling attics all day.

dont ignore those low pressure warnings, compressor gone.

boss wants overtime for free, hell no.

watched bryan orr video on superheat, eye opener.

my carrier job last week was a nightmare too.

r-410a prices skyrocketing, cant keep up.

use a digital manifold, saves headaches.

anyone got tips on leak detection?

that $800 lesson stings, but better now.

we all been there, dont sweat it.

insurance denied my claim on bad install.

check for proper evacuation before charging.

boss cut corners on my last job.

dont skip the nitrogen purge.

PE is screwing the whole industry.

unions fighting back at least.

leaks from cheap fittings kill me.

that carrier model has issues.

watched a service tech video on it.

boss made me redo a whole install.

guy in hvac techs network said same.

use sharkbites? nah, braze it.

controversial but works.

ductwork nightmares every job.

add dampers.

frustrated with slow parts.

$1200 for a coil, ridiculous.

shop around suppliers.

my first leak hunt took 4 hours.

patience key.

saw a post on r/hvacadvice about gauges.

helpful stuff there.

boss asked sketchy overtime.

or quit.

r-410a to r-32 switch coming.

ten year vet here, still learn.

keep it up.

hvac school podcast saved me.

funny client stories beat all.

lmfao.

contractor fight group full of rants.

pe rollups eating profits.

impossible alone.

braze over crimp? debate.

use nitrogen always.
