First Responder, Military, and Senior Discounts.
Every technician eventually meets:
The Last Guy.
The Last Guy may have:
Klein Cooling technicians shall evaluate previous work based on what can actually be observed and verified, not assumptions about the person who performed it.
Diagnose the equipment in front of you.
Do not diagnose the technician who was there before you.
This section begins here for a reason.
Give the previous technician grace.
HVAC diagnosis is not always easy.
Failures can be:
You have information the previous technician may not have had.
You may be standing in front of a system operating differently than it did for them.
Do not assume:
They were stupid.
Do not assume:
They were dishonest.
Do not assume:
They were trying to rip the customer off.
Maybe they simply got it wrong.
You will too.
This distinction matters.
A technician can make an incorrect diagnosis while genuinely trying to help the customer.
Those are not the same thing as intentional deception.
If another technician diagnosed:
Bad TXV
and your testing does not support TXV failure, say:
“I’m not seeing evidence today that supports condemning the TXV.”
Do not say:
“That company was trying to scam you.”
You do not know that.
Describe what the evidence says about the diagnosis.
Do not invent motives for the person who made it.
This sentence will save you from saying a tremendous amount of stupid stuff:
“I wasn’t there when they tested it.”
Use it.
Customer:
“Why did the other technician tell me the TXV was bad?”
Appropriate response:
“I can’t tell you exactly what they were seeing because I wasn’t there. I can tell you what I’m seeing today and whether today’s testing supports that diagnosis.”
Perfect.
You did not defend the other technician.
You did not attack them.
You stated what you actually know.
Remember Section 10.
Get the history.
Ask:
Sometimes the customer’s summary:
“They said my compressor was bad.”
becomes considerably more nuanced when you read the invoice.
Read it when available.
Customer:
“The other guy said it was low on refrigerant.”
Do not respond:
“Why would he say that?”
The customer doesn’t know.
That’s why they hired HVAC companies.
Do not put them in the middle of a technical disagreement.
Instead:
“Okay. Did they add any refrigerant?”
Now we’re gathering useful information.
There is a terrible HVAC tradition where one technician arrives after another and immediately begins explaining everything the previous technician did wrong.
Usually before testing anything.
Do not participate.
You are not there to conduct:
on the previous service invoice.
Diagnose today’s complaint.
If previous work is relevant, evaluate it.
If it isn’t:
Leave it alone.
There are often multiple technically acceptable ways to accomplish the same task.
Different does not automatically mean wrong.
Before criticizing another installation or repair, ask:
Does it violate manufacturer requirements?
Does it violate applicable code?
Does it impair equipment operation?
Does it create a safety issue?
Does it fail to meet an actual workmanship standard?
Or:
Would I personally have done it differently?
Those are not the same thing.
Personal preference is not a code section.
You may encounter something that is:
ugly.
That does not automatically make it defective.
A wire may not be routed exactly how you would route it.
A drain may not be aesthetically pleasing.
A component may be mounted differently than your preference.
Evaluate function, safety, manufacturer requirements, applicable code, and workmanship.
Do not manufacture a repair because:
“I don’t like how this looks.”
See Section 07.
Grace does not mean pretending bad work is acceptable.
If previous work is:
Document it.
Explain it.
Recommend correction.
Grace means:
We do not need to insult the person who did it in order to explain what needs to be corrected.
Good:
Previous thermostat wiring does not match equipment requirements.
Not:
Whoever wired this had no clue what they were doing.
Good:
Existing drain configuration does not provide appropriate drainage under current conditions.
Not:
The installer was an idiot.
Good:
Previous repair splice has visible heat damage and requires correction.
Not:
Some hack wired this.
The customer can understand the problem without receiving our review of another technician’s intelligence.
Avoid it.
There are situations where workmanship is objectively terrible.
Still:
Document the workmanship.
Unsupported air handler.
Improper conductor termination.
Exposed line-voltage wiring.
Incorrectly configured blower.
Drain pitched opposite intended direction.
Those statements tell the customer something.
Hack job
does not.
Be very careful.
You may find a system another company recommended replacing.
You may determine:
It does not currently require replacement.
Good.
Say that.
“Based on today’s testing, I don’t see a reason you have to replace this system right now.”
Excellent.
Do not automatically add:
“They were just trying to sell you one.”
You cannot establish motive with a multimeter.
A repairable system can still have been reasonably recommended for replacement.
Consider:
Another company recommending replacement does not necessarily mean they claimed:
The system cannot physically be repaired.
Understand what was actually recommended before declaring it wrong.
Also true.
You may find:
Do not soften the technical conclusion.
Say:
“Today’s testing does not support that diagnosis.”
Then show the customer why.
That statement is powerful enough.
You do not need:
“Those guys are crooks.”
Customers sometimes call Klein Cooling because another company has recommended:
Our responsibility is not to:
confirm the first company.
Our responsibility is not to:
contradict the first company.
Our responsibility is:
If we agree:
Say so.
If we disagree:
Say so.
If we cannot verify the original failure:
Say so.
See Section 14 — Free Second Opinions.
This is important.
When a customer calls for a second opinion, there can be a temptation to become:
The company that proves the first company wrong.
No.
If the first technician was correct:
They were correct.
Tell the customer.
A second opinion that confirms the first diagnosis still provided value.
We are independent.
Independent does not mean opposite.
Likewise:
Do not assume another licensed technician must have been correct.
Customer:
“They said the compressor is bad.”
Test it.
Do not begin preparing the compressor estimate before opening your meter.
Another technician’s diagnosis is:
information.
It is not your diagnosis.
This can matter enormously.
They may have:
Today’s system may not be operating under yesterday’s conditions.
Ask what was done.
Document it when relevant.
This deserves attention.
Customer:
“They added three pounds yesterday, but it’s still not cooling.”
That is diagnostically relevant.
Do not evaluate the system as though nobody has touched the charge.
Ask:
Do not assume:
Still low.
Do not assume:
Overcharged.
Measure.
Customer:
“They already replaced the thermostat, capacitor, board, and motor.”
Important.
Do not immediately replace the fifth component.
Review the history.
Determine:
If four parts did not fix the problem:
Perhaps the fifth part is not the breakthrough everyone has been waiting for.
See Section 12.
A prior repair may correct one failure and inadvertently create another.
Examples:
If the evidence supports this:
Explain it neutrally.
“The motor itself is operating, but its current configuration does not match the required airflow setup.”
Not:
“They screwed up your motor.”
Facts first.
This is the section technicians tend to forget.
Sometimes you open Housecall Pro and discover:
Klein Cooling was the last guy.
Perhaps:
you were the last guy.
The standard does not change.
Do not:
Evaluate it.
Own it when appropriate.
Correct it.
Document it.
Grace for the last guy includes remembering that sometimes the last guy wears our shirt.
Say so.
“We were here previously, and it appears our original diagnosis did not identify the actual problem. Here’s what we’ve found now.”
Then make it right according to company policy and the circumstances.
Do not construct a six-paragraph technical explanation whose only purpose is avoiding:
“We got that wrong.”
Customers can handle honesty.
What they cannot handle indefinitely is bullshit.
Congratulations.
You have achieved:
professional growth with documentation.
Do not alter history.
Do not become defensive.
Correct the problem.
Learn from it.
If necessary, tell Kevin.
Especially if the mistake is expensive.
Actually:
Definitely tell Kevin if the mistake is expensive.
Finding out from the customer’s Google review is a less efficient communication system.
A customer may ask Klein Cooling to evaluate equipment recently installed or repaired by another contractor.
Determine:
Do not unnecessarily perform chargeable work that another company may be obligated to correct without first making the customer aware when that information is reasonably apparent.
That is part of looking out for the homeowner.
Sometimes the best advice is:
“This appears related to the work they just performed. Since it may be covered by their warranty, I would contact them first.”
Yes.
That may mean Klein Cooling does not get the repair.
That’s okay.
We are not trying to capture every dollar that enters a customer’s house.
We’re trying to give good advice.
The customer does not need:
“Oh, THEM? We fix their stuff all the time.”
“Everybody knows those guys are terrible.”
“Their techs don’t know anything.”
No.
Florida has enough humidity.
It does not need HVAC gang warfare.
Discuss the equipment.
If you recognize the previous technician’s name:
Keep it professional.
“Oh, yeah, I know him.”
Fine.
“Ohhhh, THAT guy. Let me tell you…”
No.
This is a service call.
Not a reunion episode.
Customer:
“That guy had no idea what he was doing, right?”
Do not take the bait.
Try:
“I can’t speak to what he was seeing at the time. I can show you what I’m finding today.”
That keeps the conversation where it belongs:
on the equipment.
Also fine.
Customer:
“We’ve used him for 20 years. He’s great.”
Excellent.
There is no competition occurring in the living room.
If you found something different:
Explain the difference respectfully.
The customer does not need to choose which HVAC technician they love more before you can repair the system.
Previous work can teach you things.
You may encounter:
If another technician did excellent work:
You are allowed to recognize it.
“Whoever installed this did a really nice job.”
Your Klein Cooling shirt will not burst into flames.
Good work is good work.
If another technician’s documentation helps you:
Acknowledge it.
If their diagnosis was correct:
Say so.
If their repair was excellent:
Say so.
Professionalism is not diminished by recognizing another professional.
In fact:
It looks a lot like confidence.
Document observable conditions.
Good:
Existing thermostat configured as conventional equipment on heat-pump system. Corrected configuration and verified operation.
Good:
Previous invoice supplied by customer states TXV failure. Current testing does not reproduce reported condition; SH/SC and airflow measurements documented below.
Good:
Recent motor replacement noted. Motor configuration inspected due to customer’s report that comfort issue began after replacement.
Not:
Previous company screwed everything up.
Housecall Pro is a service record.
Not Yelp for HVAC technicians.
Do not state:
“The other company definitely never tested this.”
unless you actually know that.
Do not state:
“They just guessed.”
unless there is evidence supporting that statement.
Do not state:
“They were trying to sell you equipment.”
because their recommendation differs from ours.
We document:
what we know.
Remember Section 07.
When previous work or diagnosis is involved, ask:
What was the original complaint?
What did the previous technician actually document?
What did the customer say happened?
What work was performed?
Did that work change the symptoms?
Am I evaluating the equipment independently?
Do today’s measurements support the previous diagnosis?
Could conditions have been different during the previous visit?
Am I criticizing a legitimate alternative method merely because I prefer another method?
Am I describing an actual defect—or just something ugly?
Am I assigning motives I cannot possibly know?
Would I say the same thing if Klein Cooling had performed the previous work?
That last one matters.
A lot.
Give the last technician grace.
Listen to the customer.
Read the previous invoice when available.
Understand what happened.
Understand what changed.
Perform your own testing.
Do not automatically agree.
Do not automatically disagree.
Do not diagnose toward proving someone wrong.
Do not diagnose toward proving someone right.
Do not call another technician stupid.
Do not call another company dishonest without evidence.
Do not confuse different with wrong.
Do not confuse ugly with defective.
When previous work is actually wrong:
Say exactly what is wrong.
When another technician was right:
Say they were right.
When another technician did beautiful work:
Give them credit.
When Klein Cooling was the last company:
Apply exactly the same standard.
And when you were the last technician:
Well.
Now Section 13 suddenly feels a lot less theoretical.
The previous technician is not on trial.
The diagnosis is.
