To the Apprentice: Have Some Class
Before You Learn the Hard Skills, Learn the Soft Ones
You’re brand new.
You don’t know how to calculate superheat yet.
Static pressure still sounds like something your doctor checks.
Your journeyman hands you the meter and your first thought is:
Please don’t ask me to use this.
That’s okay.
You’re an apprentice.
You’re supposed to not know things yet.
We can teach you refrigeration.
We can teach you electrical.
We can teach you airflow.
We can teach you how to read a wiring diagram without staring at it like it was recovered from an Egyptian tomb.
The hard skills will come.
It takes years to become truly good at this trade, and if you stay in it long enough, you’ll eventually realize you’re never actually finished learning.
But there’s another set of skills you can start working on before you know what a TXV does.
The soft skills.
How you speak to people.
How you carry yourself.
How you enter someone’s home.
How you listen.
How you explain things.
How you behave when you’re frustrated.
How you treat someone’s property.
How you treat the technician who worked on the equipment before you.
How you respond when you don’t know something.
None of that requires five years of experience.
You can be good at it on Day 1.
And here’s something apprentices sometimes don’t understand:
The soft skills aren’t secondary to being a good technician.
They’re part of being a good technician.
You Are a Guest Before You Are a Technician
HVAC is a strange trade.
People you’ve never met are going to open their front door and let you into their home.
Think about that.
They’re going to let you into their bedrooms.
Their closets.
Their garages.
Their attics.
Sometimes their kid’s room.
They’re going to leave you around their belongings.
Their pets.
Their family.
Then they’re going to ask your opinion about a complicated machine they probably don’t understand.
And sometimes they’ll make a five-figure financial decision based largely on what comes out of your mouth.
That’s an enormous amount of trust to hand some 19-year-old kid holding a six-in-one screwdriver.
Act like you understand that.
Introduce yourself.
Look people in the eye.
Be polite.
Ask before moving their belongings.
Ask before entering private areas of the home.
Close doors behind you.
Don’t track dirt through the house.
Don’t leave tools everywhere.
Don’t lean dirty equipment against their walls.
Don’t put screws on their furniture.
And when you’re finished?
Clean up.
None of that requires understanding the refrigeration cycle.
Put the Cigarette Out
We really shouldn’t need a section for this.
Yet here we are.
Don’t pull into a customer’s driveway with a cigarette hanging out of your mouth like you’re arriving to repair the boiler at Shawshank.
Put it out.
Preferably before you arrive.
Because even if you don’t smoke inside—and dear Lord, please don’t—the smell comes inside with you.
Your shirt smells like it.
Your hands smell like it.
Your tool bag smells like it.
Now Mrs. Johnson’s hallway smells like Marlboro Red and evaporator cleaner.
Wonderful.
And vaping isn’t some magical loophole.
Nobody wants their HVAC technician standing beside the condenser disappearing into a cloud of:
BLUE RASPBERRY ARCTIC BLAST.
You’re at work.
Wait.
Watch Your Mouth
The trades have a language.
We understand.
Spend enough time in a 140-degree attic and eventually you will develop a vocabulary that would make a merchant marine ask you to settle down.
Your journeyman probably cursed.
His journeyman definitely cursed.
Somewhere in your HVAC family tree is a man who could use one word as a noun, verb, adjective, adverb and complete electrical diagnostic procedure.
That’s fine.
The tradition ends at the customer’s front door.
Don’t curse in someone’s home.
“But the homeowner curses.”
Cool.
You don’t.
“But he seems really laid back.”
Great.
You don’t.
“But he said—”
Doesn’t matter.
You’re not hanging out with your buddies.
You’re working.
Have some class.
Please Don’t Tell the Homeowner Their Installation Is Sh*t
There is something inside the DNA of every HVAC technician that makes this almost impossible to resist.
You open the air handler.
You stare at it for approximately eleven seconds.
Then comes the ancient service technician mating call:
“Who installed this?”
Don’t.
Maybe the installation really is terrible.
Maybe the drain is wrong.
Maybe the return is undersized.
Maybe the ductwork looks like somebody designed it during a fever dream.
Maybe the air handler appears to be supported by materials purchased from the arts-and-crafts section.
Fine.
Explain the actual problem.
Professionally.
“The drain isn’t installed correctly, and here’s why that’s creating a problem.”
Good.
“The return appears undersized for the airflow this system needs.”
Excellent.
“There are a few things about this installation I’d recommend correcting.”
Beautiful.
Not:
“Wow. This install is sh—”
No.
Because here’s something you don’t know.
The homeowner’s brother may have installed it.
Their father may have installed it.
Their best friend may own the company that installed it.
Or—and this is where things get particularly exciting—
Your company may have installed it.
Nothing produces personal growth quite like spending ten minutes explaining how only an absolute moron would have installed something this way…
…then noticing your company’s sticker on the air handler.
Oh.
You’re The Last Guy.
Welcome back.
Don’t Trash the Last Technician Either
Same rule.
You weren’t there.
You don’t know what the equipment was doing when he arrived.
You don’t know what readings he had.
You don’t know what the homeowner told him.
You don’t know what has changed since then.
So when the homeowner says:
“The last technician said it was the TXV.”
Your response is not:
“That guy had no idea what he was doing.”
Your response is:
“Okay. Let me take a look and see what I find.”
Then diagnose the equipment.
If you disagree, explain why.
“I’m not seeing readings right now that support a failed TXV.”
That’s professional.
You don’t need to destroy another technician’s reputation to demonstrate your own competence.
And someday you’re going to be The Last Technician.
You’ll appreciate the courtesy.
Learn to Listen Before You Learn to Talk
The homeowner says:
“It usually happens around four in the afternoon.”
Listen.
“It makes this weird noise right before it shuts off.”
Listen.
“It started after they changed the thermostat.”
Listen.
“The bedroom has always been hotter than the rest of the house.”
Listen.
Don’t interrupt because you’ve already decided what the problem is.
Don’t start troubleshooting in your head halfway through their first sentence.
Let them finish.
They’ve lived with this air conditioner for ten years.
You’ve known it for nine minutes.
The homeowner may not know the technical terminology.
That’s okay.
Buried inside what they’re telling you may be the single most important diagnostic clue you’re going to get all day.
Don’t Make the Homeowner Feel Stupid
The homeowner says:
“I think it needs Freon.”
You know that’s not necessarily how this works.
Congratulations.
You’re an HVAC technician.
You’re supposed to know more about HVAC than the homeowner.
Don’t smirk.
Don’t look at your journeyman.
Don’t give them the:
“This guy…”
face.
Ask:
“What makes you think that?”
Maybe someone told them that previously.
Maybe they saw ice.
Maybe the neighbor said it.
Maybe they Googled the symptoms.
Maybe there’s actually something useful behind what they’re saying.
Educate them.
Don’t humiliate them.
If every homeowner already understood refrigeration, airflow and electrical troubleshooting…
They wouldn’t need us.
Know When to Shut Up
This is absolutely a soft skill.
You don’t need to narrate everything happening inside your brain.
Especially as an apprentice.
You and your journeyman open something.
You see something weird.
You look at each other.
Save it for the truck.
Don’t start doing HVAC Mystery Science Theater 3000 in the customer’s hallway.
“Dude. Look at this.”
“No way.”
“Who DOES that?”
“I’ve never seen anything like this.”
Meanwhile the homeowner is six feet away thinking:
IS MY HOUSE ABOUT TO EXPLODE?
Finish inspecting the equipment.
Figure out what actually matters.
Then explain it calmly.
The homeowner doesn’t need the director’s commentary while you’re troubleshooting.
Don’t Guess Prices
Homeowner:
“How much do you think a compressor costs?”
You:
“The technician can go over the repair options and pricing with you.”
Done.
Do not say:
“Probably like $1,500.”
You don’t know.
Now the actual repair is $2,700 and your journeyman gets to spend the next twenty minutes explaining why his apprentice apparently operates a competing HVAC company from the passenger seat.
Same with equipment replacement.
Don’t guess.
Don’t speculate.
Don’t negotiate.
Don’t create:
Apprentice Pricing™
in somebody’s kitchen.
Never Tell Anyone How Long the Job Will Take
This is one of those lessons every technician eventually learns.
Homeowner:
“How much longer do you think?”
Young technician:
“Probably about an hour.”
The HVAC gods:
Interesting.
The next screw strips.
Then a fitting leaks.
Then the drain breaks.
Then the thermostat won’t communicate.
Then the vacuum won’t pull.
Then somebody discovers that the supply plenum was apparently constructed during the Carter administration.
Then it starts raining sideways.
Five hours later, the homeowner walks outside:
“I thought you said another hour?”
Never challenge the HVAC gods.
Give reasonable expectations when you can.
But don’t confidently predict things you cannot know.
This rule also applies when your wife eventually asks:
“What time will you be home?”
You don’t know.
You have never known.
Learn How to Deliver Bad News
This is a skill.
You’re going to tell people things they don’t want to hear.
Their compressor failed.
The coil is leaking.
The blower motor is bad.
The system is in terrible condition.
The repair is expensive.
Sometimes replacement genuinely makes more sense.
How you communicate that matters.
There’s a difference between:
“Yeah, compressor’s smoked. You’re screwed.”
and:
“Unfortunately, we’ve confirmed that the compressor has failed. Let me show you what we tested, and then we’ll go through the options with you.”
Same compressor.
Same failure.
Same bad news.
Completely different technician.
Don’t manufacture fear.
Don’t exaggerate.
Don’t make things sound catastrophic because you enjoy sounding knowledgeable.
Explain what happened.
Explain what you know.
Explain the options.
Then let the homeowner make an informed decision.
Look Like You Belong There
You don’t need to look like you’re going to a board meeting.
You’re an HVAC technician.
You’re going to sweat.
You’re going to get dirty.
You’re going to crawl through insulation.
Sometimes you’re going to emerge from an attic looking like you escaped from a coal mine.
That’s the job.
But start the day clean.
Clean shirt.
Decent pants.
Work boots.
Basic hygiene.
Hair reasonably under control.
Try not to smell like you slept inside the service van.
And if you’ve just spent three hours crawling through insulation, maybe take thirty seconds before walking across someone’s white carpet looking like a powdered donut.
Shoe covers exist.
Drop cloths exist.
Vacuum cleaners exist.
Use them.
Their House Is Not Your Shop
Don’t throw your tools everywhere.
Don’t put screws on the dresser.
Don’t set a dirty meter on the kitchen counter beside dinner.
Don’t leave wire clippings on the floor.
Don’t leave old parts behind unless the homeowner wants them.
Don’t drag insulation through the house.
Don’t scratch walls carrying equipment.
Don’t leave the attic access looking like a raccoon came through it.
Clean up when you’re finished.
The homeowner should not need an archaeological team to determine where the HVAC technicians were working.
Meet the Dog
You’re going to meet the dog.
There is always a dog.
Sometimes the dog loves you.
Sometimes the dog hates you.
Sometimes the homeowner says:
“Don’t worry. He’s friendly.”
The dog is displaying seventeen teeth.
Wonderful.
Respect people’s pets.
Don’t leave doors open.
Don’t leave gates open.
Don’t assume the dog can go outside.
Don’t feed it anything.
Don’t let the cat escape.
And don’t spend fifteen minutes wrestling with the Labrador while your journeyman carries a compressor by himself.
There’s a balance.
Put the Phone Away
Yes, phones are tools now.
We use them constantly.
Service software.
Manuals.
Wiring diagrams.
Equipment data.
Tech support.
Photos.
Model numbers.
Calculators.
That’s fine.
But when a homeowner is talking to you?
Put it down.
Look at them.
Listen.
Don’t stand there scrolling while somebody explains what’s happening in their home.
And if you need your phone for the job, tell them.
“I’m pulling up the manufacturer’s service information.”
Now they know you’re working.
Not checking Instagram while their house is 86 degrees.
Your Journeyman Is Watching More Than Your Technical Ability
As an apprentice, you think your journeyman is evaluating whether you know HVAC.
He is.
But early on?
He’s probably watching something else much more closely.
Did you show up on time?
Did you listen?
Did you carry something without being asked?
Did you clean up?
Did you respect the homeowner?
Did you put your phone away?
Did you watch your mouth?
Did you close the gate?
Did you protect the floors?
Did you admit when you didn’t know?
Did you treat the customer’s house like it mattered?
Because here’s the good news:
We can teach you HVAC.
We can teach you to use a meter.
We can teach you refrigeration.
We can teach you airflow.
We can teach you electrical troubleshooting.
We can teach you how to diagnose a system.
But if you walk into people’s homes disrespectful, arrogant, filthy, foul-mouthed and completely uninterested in learning?
That’s a much harder problem to fix.
Ten Minutes Now Saves You Two Hours Later
Here’s another soft skill you’ll eventually learn:
Slow down.
Ten minutes spent listening to the homeowner can save you two hours chasing the wrong problem.
Ten minutes reading the installation manual can save you two hours trying to understand why the equipment isn’t behaving the way you think it should.
Ten minutes tracing the wiring can save you two hours replacing parts.
Ten minutes cleaning up properly can save your company an angry phone call tomorrow.
Ten minutes explaining something clearly can prevent thirty minutes of confusion at the kitchen table.
Young technicians are always in a hurry.
Experienced technicians eventually realize:
The fastest way through a job is often to stop rushing.
Ten minutes now saves you two hours later.
Remember that one.
The Customer Probably Won’t Remember Your Subcooling
This is something you won’t understand until you’ve been doing this awhile.
You may perform technically perfect work.
Perfect refrigerant charge.
Perfect airflow.
Perfect electrical diagnosis.
Everything documented.
Great.
The homeowner probably won’t remember any of those numbers.
But they’ll remember:
“That young man was incredibly respectful.”
They’ll remember that you listened.
They’ll remember that you explained things without making them feel stupid.
They’ll remember that you cleaned up.
They’ll remember that you were kind to their dog.
They’ll remember that you didn’t pressure them.
They’ll remember that you treated their home like it mattered.
Years later, those things are worth more than you think.
Technical competence earns trust.
Professionalism makes people remember it.
Someday You’re Going to Be the Journeyman
You won’t believe this yet.
Someday the guy you’re riding with won’t be there.
You’ll pull up to a customer’s house.
And there will be some 19-year-old kid sitting in your passenger seat.
He’s been in HVAC for approximately eleven business days.
Naturally:
He knows everything.
He’ll interrupt the homeowner.
He’ll guess a price.
He’ll leave a gate open.
He’ll promise you’ll be finished by 3.
He’ll open the air handler and loudly announce:
“Man, whoever installed this thing—”
And you’ll slowly turn your head toward him.
In that moment…
You will finally understand your journeyman.
Try not to throw a pipe wrench at him.
We’re trying to improve the trade.
Teach him.
The Hard Skills Will Come
Someday you’ll understand the things that completely confuse you today.
You’ll calculate superheat without thinking about it.
You’ll understand subcooling.
You’ll diagnose electrical problems.
You’ll understand airflow.
You’ll read wiring diagrams without feeling like you’re deciphering hieroglyphics.
You’ll walk up to problems that once took you three hours and recognize them in ten minutes.
That comes with time.
Professionalism doesn’t require time.
You don’t need ten years in HVAC to respect someone’s home.
You don’t need a journeyman card to listen.
You don’t need NATE certification to say please and thank you.
You don’t need to understand psychrometrics to know you probably shouldn’t vape Blue Raspberry Arctic Blast in Mrs. Johnson’s living room.
And you definitely don’t need five years of field experience to understand that saying:
“Whoever installed this had no idea what they were doing.”
might become slightly uncomfortable when you notice your company’s sticker on the equipment.
Learn the soft skills while we’re teaching you the hard ones.
Because eventually, you’ll have both.
And that’s when you stop being a guy who knows how to fix air conditioners…
And start becoming a professional.
Put the cigarette out.
Watch your mouth.
Listen.
Respect the customer.
Respect their home.
Respect the technician who came before you.
Clean up after yourself.
Don’t pretend to know things you don’t.
Don’t promise you’ll be finished in an hour.
And please…
Don’t tell Mrs. Johnson her install is sh*t.
Have some class, kid.
You’re a professional.
