A customer can't tell if they are dealing with an average technican or a great technician. A great technician will inspect everything not just what the original service call was about. Here is a scenario. . . .

Let’s say you find a failed, shorted compressor on a 7-year-old system that still has manufacturer parts coverage. If you simply quote the compressor and leave you may be missing a lot of other maintenance-related issues that can affect operation once the compressor is replaced. A shortlist of items to check would be –

Look at the accumulator for signs of corrosion
Acid test to see if a burnout protocol should be employed
Check the air filter
Inspect the condenser coil cleanliness
Look at the underside of the evaporator coil
Perform a static pressure test on the system to check for duct issues
Check the crankcase heater (if it has one)
Inspect the contactor
Check condenser fan and blower motor amps
Test all capacitors
Visually inspect wires and cap tubes
Check high voltage electrical connections
And this is just for cooling side issues. If the system is a fuel-burning appliance you would inspect every part of the furnace operation as well.

Venting
Condensate drainage
Burners
Flame proving
Safeties
And much more…

Testing all of these things is commonplace AFTER a repair, but it makes so much more sense to do it beforehand so that you can either charge appropriately for any of these items that need to be addressed or let the customer know you are including them to differentiate you from the competition.

Things to Do Along With Major Repairs

There are a few things you need to do as a matter of course during major air conditioning or refrigeration repairs that just make good sense to prevent callbacks. You can include them in the price or not or not but either way, it will save you more than it costs to do it.

Clean the drain line and condensate pan (seriously…. do this)
Wash the condenser coil
Clean the blower wheel (if it is dirty)
Change the air filter
Test all modes of operation
Do these things along with all of the standards tests you perform to make sure that you have no issues and that whatever caused the fault in the system has been rectified and you will save a lot of problems. When the customer spends a lot of money getting a system fixed, they don’t want to turn around and have it fail for an “unrelated” reason.

These things are what separates an average company or technician from a great company or technician. Making sure that the customer is happy and confident that their problem has been resolved. Most customers will sacrifice price for quality and assuridness.

Here is another tip on "Trial and Error" that I thought may be useful to anyone who may be curious. Scroll down to read more. . . .

I’m far from a country boy but I did grow up in a rural area with animals, playing in the woods and cleaning out chicken coups. Like many of you, we would play most of the day outside without our parents knowing or worrying about where we were.

Was that an “unsafe” way to grow up?

I guess it wasn’t always perfectly safe but it did result in a lot of unintentional learning as we navigated the world around us and gained experiences and feedback via trial and error.

It’s undeniable that one of the quickest and most reliable ways to learn is to try and fail until we get it right.

It’s how you learned to ride a bike, rollerskate and probably how you learned to swim.

Like David Sandler said –

You can’t teach a kid to ride a bike in a seminar

We know it’s true but so often we attempt to teach topics through talking and reading and writing and watching rather than allowing people to learn through good old trial and error.

The problem with the “trial and error” method of learning professionally is the “error” part of the equation and the potential cost of those mistakes.

Learning From Mistakes Without Disaster

I have a friend who works as a nuclear analyst for power plants. He learned much of what he knows in the Navy while working on a nuclear submarine. On a nuke sub you can’t afford to “learn from your mistakes”, a mistake that could kill everyone and possibly bring an end to civilization isn’t a mistake you can risk. In these mission-critical environments, the military doesn’t resort to teaching the book over and over without practice. Instead, they do drills and work through redundant checklists with hands-on practice over and over and over.

It isn’t that they remove practice and trial and error… far from it. Instead, they allow the trial and error to occur in an environment where the mistakes are controlled in a way that can NEVER result in a mistake in real life.

In other words…

They don’t practice until they get it right. They practice until they can’t get it wrong.

Previous generations understood the importance of drills and practice where more modern education has focused on cognitive understanding as the foundation.

Understand it first and then you can do it. It’s as if understanding all about a bike, the chain and how it made, the gears, the brake mechanism etc… must be learned first before a kid should get on the darn thing and learn to ride it.

Often it’s nerds like me that try to force-feed new people a bunch of technical mumbo jumbo because it interests me rather than helping them get on the bike so they can learn how to turn and peddle.

Applying Trial and Error Into HVACR

We can all agree our trade faces an honest to goodness shortage of skilled workers that is only getting worse. We can sit in our ivory palaces and pine away about how to give everyone a perfect education with every detail listed out and taught in a nice clean classroom but it won’t work and it’s too little too late.

In order to get people trained fast we need to allow them to put their hands on tools and equipment in realistic situations and practice, practice, practice until they can’t get it wrong. We need to shorten the list of things we expect workers to know in their brains before we start to allow them to experience it.

After talking to world-class, innovative instructors like Ty Brannaman with NTI I am learning that narrowing down the curriculum and giving more tool time earlier in the training is leading to much better outcomes.

This doesn’t mean that we aren’t teaching safety and compliance but that we are teaching it as a part of drills and practice rather than separate from it.

It means piing in equipment over and over with modern tools and techniques. It means charging, recovering and evacuating over and over until they can do it in their sleep. It means wiring and diagnosing electrical issues that will actually be seen in the field on the sort of equipment they are likely to see.

It means practice and trial and error before being so heavy-handed with books and theory.

Came across this and found it worth sharing. .

The Slow Death of the Honest Technician
By Bryan Orr on Nov 23, 2019 09:13 am



I was sitting in a session at the HVAC Excellence educators conference (which was excellent by the way) and my phone buzzed. So like a typical punk kid I looked down at it to see that my friend Josh had sent me a Facebook message asking if we served the East side of Orlando because he wanted an A/C maintenance on his home. I told him that we did not serve that part of town and I didn’t think anything else about it.

Then yesterday I see this post

So we go out to look at it, and sure enough. The system is BARELY low, like 3 degrees of subcool low and we added 1/2 of a lb of R22 (weighed in) and did a leak detection. Yes, there was a TINY leak in the evaporator coil so Josh will probably end up getting a system at some point… However, the other tech did not do maintenance at all, he did not quote a coil or anything other than a system. He literally showed up, saw the unit was 14 years old, pulled out his leak detector, found a hit and wrote up a proposal for $5400.00. He tried to close the “deal” right on site. No load calculations, no looking at the ducts, just a leak detection, a proposal and run.

How many 14-year-old units have zero leaks?

He didn’t clean the drain or the condenser coil, he hardly even checked the charge. Heck, Josh has a UV light that wasn’t even working due to a simple loose connection, he didn’t look at that.

Unfortunately for this company, my friend Josh is a local consumer advocate who goes on local TV news REGULARLY to talk about ways to save money and EXPOSE SCAMS.

When I contacted the owner of this business to try and reason with them they wrote me back that they were going to report me to the EPA because we recharged the unit. When I explained that recharging R22 on systems under 50 lbs is perfectly allowable they responded with more threats and emotional rantings.

The standard narrative is that there are just a bunch of greedy scammers out there trying to take advantage of people. Clearly this is true sometimes, but many times the story is longer and sadder than that, often this type of thing happens when well-meaning people get worn down.

Tell me if this sounds about right.

A new tech get’s hired into the trade, maybe he has some schooling maybe he doesn’t, either way, he get’s his EPA license and starts riding around with another tech. The tech he rides with spends most of the day complaining about his boss, dispatch, other techs, customers and politics but almost no ACTUAL training. When they arrive at the job there are two main objectives

#1 – Get in and out as quickly as possible with as little work as possible.

#2 – Sell as much as possible during that short time. This can be hard start kits, capacitors and surge protectors some places, IAQ products others and some it’s always finding a way to push a new system. For many, it’s all three.

Usually, this makes the new tech feel at least a little uncomfortable but this starts to fade as the days of riding around whining broken by short stints of selling continue.

After a few months, the new tech is put into a van with some parts, pamphlets, invoices and proposal forms and set loose on the world. If he is smart, he realizes pretty quick that when his bosses talk about customer service what they really mean is making as much money as possible in a day with as few customer complaints and callbacks. Usually, the easiest way to do that is to condemn everything, when a system is replaced nobody ever knows if your diagnosis was correct or not. When you do a PM there is always something you can point to as a major issue that gives you an easy out, cleaning, after all, does not ring the register.

Techs justify their behavior

When I was still in trade school back in 1999 I participated in a skills challenge against other students from schools across Florida. There was another guy who was already working in the field and I remember him saying “I never just change one part, I change as many as I can and the customers never know the difference and their unit will last longer”. I was appalled then as I am now by this type of thinking but I’m pretty sure he honestly believed he was doing the right thing. He had been brainwashed into thinking that this was what being a technician meant.

So this all begs a question, who is to blame and what can be done about it?

The Root Cause

It is just easier to make money when you focus on selling instead of technical excellence. You can be great at what you do and still not make a profit but when you FOCUS on profit at every level you will usually make more of it…. for a while.

I actually blame the quality techs and companies who don’t charge enough for what they do as one reason this happens.

I have been one of these contractors for years. We squeaked out a meager profit every year driving used vans, using cheap tools, trying to make ends meet and praying the vans don’t break down. All the while, the sales-focused businesses have new trucks and spiffy, clean uniforms.

The good guys need to stand up and stop apologizing for what we charge and what we do. we need to CHARGE for the high-quality maintenance we do so that we actually make a profit on it. We need to diagnose the whole system and make quality recommendations to our customers based on the solid and complete diagnosis we perform. There is no reason we shouldn’t be able to afford quality tools and a well-stocked van if we are the ones WHO ACTUALLY KNOW HOW TO USE THEM.

Instead, we beat one another up on price and undercut one another, calling another good, quality company who charges more a “rip off” or a “scam” just because they have their pricing figured out to where they can actually make a profit.

This company who went out my friend Josh’s house was going to charge $5,400.00 for a 3.5 ton 14 SEER Heat Pump system, that isn’t a crazy price but to some, it may be seen as a “ripoff” because they would charge $4,500.00. We might charge $6,000.00 for the same system… with a new return liner, and line set, installed with nitrogen flowing, evacuated to 300 microns, with a proper load calculation, permits and a perfectly weighed in charge confirmed by manufacturers specs to a proper subcool.

The “Ripoff” is the one who doesn’t deliver on their promise, not the one who charges more.

What to do about it

If you are a manager or owner of a company make sure you are supporting your techs to get more TECHNICALLY sound and support them to use those legitimate technical skills to translate into profitable repairs and quality workmanship. Communication skills are key in a residential tech, a tech who understands IAQ like the back of his hand will naturally sell more IAQ products, a tech who understands airflow and duct design will sell more duct upgrades and the tech who understands complete system performance will make more needed repairs. This is a long road and there are no shortcuts.

R22 isn’t illegal, not every customer needs a UV light, a hard start kit doesn’t magically extend the life of all compressors, every PM isn’t an opportunity to sell something and every system out of warranty doesn’t NEED to be replaced.

If you are one of the good guys let’s band together, keep our heads up and charge enough to have a good life.

The hottest days are coming!! Make sure to have ur Central AC serviced by a reliable company. If u have a window unit, no one in the phone book will service it. . . that's why i started C-unit repairs almost 10 years ago!!! I've been taking them apart and cleaning them since 1992!!!!! As long as ur compressor works, i can make the air quality MUCH BETTER!!!!! INBOX ME FOR INQUIRIES!!!!!
