The top 5 mistakes HVAC techs make when troubleshooting.

[@tomdonald2495]

Ive made every one of those mistakes and a whole lot more but that's how I learned. I payed attention and got good grades in my tech classes but I felt like I didn't know shit when I got out there. Trial and error and company willing to teach got me through it. Don't be too proud to ask for help.

I had a large room in a titanium manufacturing plant that was cooled by 2 Lennox 2 stage RTU’s. They were not bringing room to set point but we’re trying to cool. I automatically cleaned the condensers and called it a day. Call back a week later same problem. I finally figured out 2nd stage cooling wasn’t coming on. Replaced Honeywell economize controls. Ect…. After scratching my head and several call backs I finally realized the thermostats we’re not set up for 2 stage cooling and economizer… this was the first year of being a service tech. I’ve learned a ton from messing up over the years. Thanks for making this video. A lot of guys in the industry need people who care about furthering education for others. I tell my buddy all the time that HVAC/R number one problem is journeyman who don’t have the patience to teach new guys

[@Garth2011]

Thats a good one. Always "reboot" the thermostats because you have no idea how messed up the software is by the folks that programmed the setting before.

[@SonsofIssac]

Another learning experience: I installed a 2 ton with furnace. It was a piston metering device factory installed. Started up ac and couldn’t get target superheat to save my life. After spending hours adding and subtracting refrigerant and measuring temp splits and cfm over evap I finally realized that the evap was a 3 ton so the factory installed piston was a 3 ton. Pistons need to be sized for the condenser which was a 2 ton. Changed out the piston everything was fine. I’ve fixed 2 other units since then that were only getting 13-14 degree splits and had wrong size piston for years…. All because that install screw up stuck in my head. Experience is the key

[@exclusive_148]

omg i went through the same thing! we did a beautiful install and it came with a piston and my superheat was really low. And then i found out that the unit comes with an r22 piston from factory and i needed to install the 410 piston.

[@seanoneil1681]

Every company or self employed technician needs to have & follow 5 basic steps for every service call. I agree with everything you said except #3. I believe you have to prove & diagnose with a meter. I see to many techs grabbing their meter & measuring (and they'll call me & say I only have ....... this reading. I always ask " Well what's it supposed to be?" Always silence, 😆 Basically don't take a measurement if you don't know what the measurement is supposed to read anyway. A lot of problems can be found using your best tools you own. Your eyes,ears,nose & hearing. Then get your meter & confirm diagnosis. Either way great video!

I've been in construction for forty years and just succumbed,in the last few years, to learning all/many things about HVAC and, this video is so right on, not just for a/c but, for just about every trade I can imagine. And the part about asking the client what is going on first, is in my opinion, the skill/procedure, without which, no one should be a service technician or even handyman, without. Great presentation.

Just like when you go the dealership the service advisor will ask when does it happen, night only day time..high humidity days? Was it cold that day since their complain or it always does it when its cold or hot days or even rainy days

[@rickl5938]

Eric, you are spot on. The most important thing to do to understand the problem the customer is having is to talk to them. The second most important thing to know when troubleshooting is the equipment's sequence of operation. I can tell that when I worked for other people I unfortunately never had a service manager that understood the importance of this, all of them were parts changers, even though one of them had actually taken a two year HVAC course. Sad, but true. That's when I decide to go out on my own since I knew I could do better than what was already out there. Thank you for this video! All five points are critical to successfully troubleshooting an HVAC system. I retired in 2022 after running a very successful HVAC business. I often out-troubleshot the BIGS'S technicians, but why was that? The reason was, first of all, I knew my stuff, second of all I knew how the equipment was supposed to work, and thirdly I followed a logical step-by-step process(i.e. what is supposed to be happening and why isn't it) to solving the problem. Eric, I wish I would have been able to work for you. Hope you're having a wonderful life and thanks for imparting your knowledge on us.

i found that alot of service techs when they work on units,they make wiring changes .the unit worked before so don t change wiring.

[@georgekolos5255]

Many times after 30 yrs expierence I change wiring or add controls/ fuses etc. to make system better. EX 4 single pahse condenser fan motors on a unit power split from a single 3 phase contactor with 3 fuses. One of 3fuses fail entire system down because manufacturers took control power from it. Other 2 fuses if they fail would only take out 2 of 4 fan motors and worse one fan failing electricly can cause the other fans to fail. Split circuit apart protected each motor with separate fuses moved control power etc.

Thanks for your input. New service techs need you!

[@hvacservicementor]

You bet!

[@keetondabber]

Im commercial so yes and no, I've gone the very professional route and I personally like the friendly people person route and so do my customers, creates a relationship. I say hello, have a small convo allowing them to lead and in the midst I ask if they're having any issues with their system, then I check the thermostat and tell them I'll be on the roof, etc. If it's a service call then I walk in and say I heard there's an issue wirh your AC? Or HI I'm from ___, here for your ___. Personally haven't been unable to fix something that another tech/company couldn't fix so that's made us look good haha. If it a service/emergency call then I've learned that it's best to go through the unit just like a PM and pay attention to the sequence of operations and you'll usually find your issue. Learn how to read wiring diagrams and realize that there's wording on the physical wire matching the diagram! And always test in, test out. I'm little over 2 years in and these are some things I've learned. Your video is great! some of these tips are common sense to me but I hope they help others. I've seen some shanty work before in my long 2.5 years lol; if you don't know then ask your peers! Nothing worse than pretending like you know something and your coworkers having to come behind you to fix it.

IMO some people can't be taught to be service techs. You either have it or you don't. If you don't enjoy solving problems and troubleshooting you won't be a good service technician. Too many guys I train think that they can be shown everything. They don't understand the thought process.

[@robertshay9951]

Correct! In a 4 year span I had 47 Helper/Apprentice candidates only 7 made the grade 3 are in trucks doing service 1 went on to a hospital 1 left to do just residential hvac , 2 only wanted to install. 40 just could not or did not want to do the job. even after spending a lot of money at a trade school. The company that I worked for was a refrigeration/HVAC (light/medium commercial) contractor. Most of them had no mechanical skills at all, much less a problem solving mindset.

[@Mr_Daddy1980]

Totally agree. Not everyone understands that in order to be a good troubleshooter you have to understand what the system is doing. Just replacing a failed part doesn't always solve the problem. You have to figure out what caused the part to fail and in order to do so you have to understand what the unit is doing.

[@normanboyes4983]

Good video and some excellent learning points. Fault finding is essentially a game of logic which essentially means that for the inexperienced it will take time but you will find the fault eventually - if you follow the logic. An engineer with experience brings a new tool into the game and is able to know from the symptoms and his experience the ‘fuzzy logic’ element to find the fault easier and faster. Fuzzy logic is multi factorial and involves, probability, carrying out 30 second tests before 20 minute tests, examining easy to access components before something that takes a 20 minute rip out to access. (Retired marine engineer 😉).

[@hvacservicementor]

100 percent correct! When students learn that type of logical thought process for the first time it takes 30 to 40 minutes for simple problems. Once ingrained, it takes around 3 minutes!

[@elgringoec]

I think it takes a certain type of mind to be amenable to the troubleshooting process in general. It's one thing to follow a set of instructions, some may call that troubleshooting, but a true troubleshooting mind makes its own instructions on the fly.

The problem with talking to the customer is that many technicians actually get in trouble for talking to customers. This is the case especially for commercial customers. What the technicians need to know is what to talk to the customers about and what not to talk to the customers about. They need to be taught this so they don't learn the hard way, they need to learn how to sympathize with the customer with out bad mouthing the other company, the other technician, the equipment, the building, the employees who set the thermostat etc. Its a social skill that many technicians do not possess. In commercial you are simply told , "do not talk to the customer", but just like you said, you must at least listen to what the customer has to say describing the problem, its really essential in commercial just for the fact alone a building can have several pieces of equipment, how do you know where the problem is if you don't listen to the customer? what floor is it on, what part of the space is it, how do you get to the roof, etc. I can go on and on on how to troubleshoot..

[@Garth2011]

Yes, they need skills in more ways than one that is all about HVAC. In just about every profession, you have to have "bedside manners" with the client weather you like it or not so may as well brush up on them. That's part of customer retention too, even if its not your business, you will at least have your customers calling the boss and your holding a job.

Methodical thinking. I always learn from discussing with my customers what is being experience

[@alejandromata825]

11:36 talk to the customer, Check what if anything is actually functioning on the unit (if your fan is working you clearly have power), if the unit is doing nothing then you check incoming power followed by control power. -if your fan is running, put your hand on the liquid line and lift the float. Did compressor start? Is there water in the cup? Check the drain. -Put a thermometer in the plenum. What’s your delta? Are you going to be looking for a refrigerant side issue or an air side issue? -maybe your compressor never started. Now you are going to the condenser. Do you have power out there? How about signal? Check your contactor and your capacitors. Are your safety switches open or closed? Do you have gas? Is condenser fan of compressor locked up? Still between 30-45 minutes in, let’s go, let’s go! Is the problem intermittent? Go back and recheck the tstat, does the temperature it is reading sync up somewhat closely with your thermometer? Is it running a program? Is the E-Prom going bad? If everything worked like clock work and was within range and the drain looked clear but you blew it out anyway, and the customer says it’s cooling and the temperature suddenly goes from 72-78 at night or randomly change the T-Stat at the very least. It’s a good starting point for solving an intermittent problem before suggesting a board change. Or after communicating with the customer you both may decide that a better strategy would be to jump the board temporarily (keeping the safeties in circuit of course) and schedule a return for a final solution after a few days. So if problem continued with a jump board then it was the stat, if it stopped it was the board. Some boards are not possible to jump though.

[@davidsaldate1562]

The perfect video I was looking for. The installer does not listen! Since installation of my new split system, it suddenly freezes. I complained so much to the installer and they finally abandoned me because I kept complaining and they kept blaming different things, such as the cheap air filter, the cheap home insulation, not enough ducts helping air flow and finally they said my duct system is too small for the new ac system. If this is the case, I wonder why they installed a system that did not fit my home ducts system capacity; they were supposed to be just replacing the old one with a new system because the old one had a gas leak that could not found. I also am not sure why the system works fine for days or weeks by normally starting and stopping, cooling my home normally and keeping the set temperature, until all of a sudden, the compressor start, but not the air blower in the attic. It only takes about 2 minutes before the ice starts forming in the lines in the compressor outside. I then just need to turn off the system, wait for the ice to melt, start again and I am good for another day or another couple of weeks until it happens again. I am not sure why the air blower fails to start with the compressor as it normally does. I do notice that it happens more often right before and throughout our monsoon time when it starts becoming humid and it starts to rain. I also have noticed a few times that the system starts normally but my TV turns off and on in a flash, this happens only once in a while and only noticed this only the last summer. I never noticed this one before. Since my installer gave up on me, they promised to give me a new system, which never happened, they did not answer my calls nor replied to my voice mail, I considered having another ac local company check my system and I was told my system was fine, I was charged for the visit, and I was asked to call "when it happens again". But, how can I make it fail?! I also have discussed this issue with other AC professionals that maintain the buildings for the company I work for but I believe they think I am crazy. Since I was concerned about my puppy in the house and me being out of the house the whole hot days and not knowing when the system was going to fail, I replaced the thermostat with a smart thermostat that will send me an alarm to my phone if the temperature in my house is higher than set. When it happens, I just turn it off remotely using my phone, wait about 5 minutes, restart it and temperature goes back to the programmed within a few minutes. I am helpless. I seem to have a problem nobody believes I have and nobody wants to deal with. Sometimes I wonder if it has something to do with the capacitator. Anybody has any ideas? Take into consideration the random times TV quick turning off and on when the system starts. It only affects the TV, and not the AV system nor the Amazon Fire TV Stick, which are all connected in the same outlet on the wall. Isn't the capacitor supposed to help the start up by avoiding a sudden power drain? Thank you for sharing these awesome videos!

[@toddtavares7386]

While I am not an HVAC tech, I agree that talking to the customer should always be the first part of troubleshooting. What is more important is a thorough knowledge of the system operation. Often, you are listening to the customer and formulating your plan, but the customer tells you things you know can not happen. (I'm an elevator tech btw). As far as the guy that always checks the power supply; in highly processor/mirco processor/networked processors/software based systems, this definitely IS one of the first things you check; especially if there is communication problem or you suspect the problem is software/hardware and not in the field. On a 5 volt logic circuit, even a reading of 4.7 or 4.8 vdc can stop the hardware from running the software.

Compressor and fans all running and no frost at evap, Compressor is rated at 9.6 A but measures at 4,9A. Compressor sounds like it is running but loafing. I find no signs of leakage, like oil mess. I get a small amt of cooling at duct like maybe 5f. Whatever the remaing charge is, it seems stable over days. : Do compressors fail to compress well and go bad like this? Do the copper line sets spring micro leaks? I must inspect yet.? Do metering devices get restrictive suddenly and quit? I have to get a gauge set. And recharge. Hate the gas cost if no luck. I do suspect loss of charge, but cannot find source. All coils are clean and dry. I am finding no clues. Very puzzled! ;

Sounds like a leak.

Dont let those crazy Kevins and Karens mess up a good strategy 😂

To be fair, I'll often round anything within spec of 120 volts to 120 volts. Like if it actually reads 119.4 I'll just say 120 for brevity's sake. Also, I'm never going to remember that number anyway. I just mentally round to 120 volts if it's between 110 and 125.

Hi ma’am I’m Johnny I’m here to look at your air conditioning system. What seems to be the problem. 90% of them say the thermostats broken I turn it on and it blows hot.Most of them will tell you to thermostats broken because that’s the only thing that they know.

[@Garth2011]

I doubt they are going to ever suggest a run capacitor for you.

I call parts switchers tube jockeys. The old television repairman came into your house with a suitcase full of tubes, and just plugged in new ones until the set worked. If that didn’t do it, he was screwed

There was some good advice but rather general except point 1. Was hoping you'd be more specific as to the situation and resolution of the top five.

There’s a big misunderstanding when checking switch normally open. Tech always say I am getting voltage on time delay but blower motor still doesn’t run .This means the delay switch is open ,reading voltage means the switch the switch not close. This easily can check with voltage meter

ok so, that same issue you talked about "having this issue on cold nights (drain problem for example)" i've had that same issue with 2 customers being float tripped with a single trap on a neg pressure cabinet and a 0.5 static or just a little over and chalked it up to "dont run your damn ac to 65 on cool when its 45 degree outside"... i'm no rookie been in the trade for 13 years but for the life of me i could not pin point why that only happens when its cold (its never cold in florida btw).. thoughts?

[@hvacservicementor]

I was referring to condensing gas furnaces that will trip a pressure switch only during extended run cycles due to a slow drain. Not sure what you may have had there.

I love the techs. that shotgun. They never know what they fixed.

“I don’t know “ is the worst thing to hear when you ask the kid any question when they call for help, like guy , you should know the basic measurements and readings needed to attempt to troubleshoot any equipment,I hate it cuz then I’m the dick who tells him call me back when you have the readings I need then I can try to help you , lazy shit kills me , wants me to do his job for him , you gotta try before calling senior tech for help , know the basics at least , it’s not a lot of work either to start off

The 23-yr experienced HVAC tech arrived, asked me what was going on with my gas furnace heater. I told him. He diagnosed the problem in 20 minutes flat. Warranty part arrived, he replaced it within 30 minutes. Problem solved.

[@warrensmith1005]

PLEASE HELP!!! My tenant said the air is not coming out. So I called for the company that installed the Goodman product. He said the compressor went bad, so I paid for a compressor. Then he tells me that there is broken metal in the in-lines. HOW DID METAL GET INTO THE IN-LINES??? The lines have to be blown out. HOW DOES THIS HAPPEN? Have you ever heard of such?

[@williamswan7779]

no sound

[@abbottmechanicalservicesll4464]

What I do is turn fan on. If it blows I just eliminated no voltage (120 volts) ,no 24 volts. No blower

[@ptszmurlo]

Exactly…
