PSA: Newbies, don't DIY mini-split installs like I saw in zone 5 last week

Listen up, I'm a veteran tech in north jersey, zone 5 winters hit hard here. Saw a homeowner try to slap in a Mitsubishi Hyperheat unit himself after watching some YouTube vid, ended up with a $4500 refrigerant leak nightmare when it froze solid first cold snap. Total crap-show, had to evacuate the lines and recharge with R-410a, took two days. If you're green and thinking of cutting corners on a $3000 install, just call a pro, it'll save you headaches and cash. Mentioned this in HVAC Techs Network FB group, bunch of guys agreed it's a common screw-up. IME, always check superheat and subcool before walking away, especially in our climate. Shoulda known better, but newbies gonna newbie.

god damn it, why do people think they can handle brazing lines after one video? pissed me off last month on a similar job.

frustrated as hell with these diy disasters, boss made me clean up a frozen evap coil yesterday, wasted half my day.

same here man, knees are killing me from crawling in tight attics fixing their messes.

homeowners and their cheap fixes are ruining the industry, screw 'em for not hiring pros.

PE vultures circling HVAC shops now, gonna jack up prices and quality goes to shit.

sharbite fittings in refrigerant lines? nah, fight me, they hold up fine if you torque right.

use fieldpiece gauges every time, saved my ass on a subcool issue last week.

customer calls at 3am cuz cat knocked over the outdoor unit, had to laugh while resetting it.

inspectors in our area are the real villains, nitpick every braze joint.

hit 200k this year specializing in heat pumps, zoning the supply runs was key.

why even bother with r410a anymore, go prop65 compliant and charge more.

walked into a job where lineset was kinked bad, took forever to straighten.

hate when helpers forget to pull vacuum, ends up leaking right away.

been there, customer blamed me for the install fail.

haha, remember that time the unit shorted cuz of a wet board? comedy gold.

test run the system for 30 min before handover, catches 90% of issues.

braze with nitrogen purge, prevents oxidation every time.

diyers think they're pros after one blueridge install vid, then call us panicked.

don't skimp on line set insulation, saw a condensation flood last summer.

boss had me bypass a safety switch once, sketchy as hell but paid well.

newbie here, thought i could wing a charge, ended up over by 5 degrees.

lol, overpressured my first rig, gauges pegged and i panicked like a noob.
