I would

Sorry for the late reply, but I completely agree. its easy to be a know it all, but not anyone knows it all.

Your forgetting crap boss always trying to rush it. “ I want a 3hr job done in 15min” lol

@@chriswhalen5711 Yes sir , They want you do all the of that and you have to up sale .

Maintenance should pretty much just be washing the coils checking caps , contactor , belt , drain , loose connects , changing filters. Anything else is a service call

How you doing in commercial? Those controls look scary af

I graduated school struggled to find a job and 2 years later finally found a job in commercial HvacR and Tommarow I am bout to start pms

Compensation totally agree I’ve burned once

Thanks for the tip, so many things to cover it is easy to miss some detail. hell, if we can get guys just to pull out the hose and wash coils we have achieved total success. lol

Facts

Why off to the side and facing away ? In case it blows up ?

@@Hvacmania yeah, the arc flash will blow outwards when it blows the door off. There are some videos floating around showing it. But be careful what you watch as some were incidents with people involved who didn't make it. I think there is a 20 amp service disconnect that they tested on a dummy so look for that.

its a great trade, you can never stop learning. Learn as much as possible, do good work and your reputation will carry you to a great career.

Learn more = more overtime

How long was the course?

I'm also going to be starting in the trade of HVAC in a few weeks. How have you been doing so far?

@@4oh4n0tf0und I start on on the 18th😝

agree on the smart probes, i use Testo myself. for the average PM guy, it is difficult to purchase such a pricey tool, not many techs can afford it especially starting out. Often times they forget the fundamentals that is why we stick to mechanical gauges and PT charts.

I find that false. Shut off fittings and you'll release hardly nothing. The only thing smart probes are good for is, time. For people starting off, especially doing PMs then you should learn the gauges first and the pressures. BecUse guages do things the APP won't tell you unless you're an EXPERIENCED Tech. TXV is a main reason for guages Here the other issue, You have to send them in to have it recalibrated. I can recalibrate my Brutes with my thermostat screwdriver. Guess what. I have all three pairs. When you second guess the probes you go back to ol trusty... So no, smart probes are not worth it and it's horrible advice to give to new people

Is there another way of checking the refrigerant charge without putting on the gauges? Like a temperature difference delta t type method?

I don't agree that smart probes are only for the experienced techs. If your are truly interested in learning the trade, the learning curve is much faster with the newer equipment than the old. I can't even imagine going beck to a micron gauge that I couldn't plot on my phone. What a learning tool that is for a new tech to actually be able to see the difference in a leak and refrigerant or water gassing off in the system. Unlike analog gauges, smart probes allow the tech to easily think in saturated temperature rather than pressure from day one! That's priceless! New refrigrant comes along there's no difference in the saturated temperatures. How many new or old techs are going inside to sling a sling psychrometer, when charging a piston? The problem isn't the new technology! It's employer's that don't want to put any training into their employees. An apprentice needs a year or two following an older tech in the field and then support for a few years after that. If he can give me good measurement's over the phone we can walk through most any refrigerant problem. Then to top it all off the manufactures are cutting back on tech support at at time when their equipment is getting more and more complicated for new and old techs alike. Apps like MQ can give the newer tech confidence in their diagnosis, if it is used after they make an attempt at diagnosing the system first. If it doesn't agree then they need to dialup a senior tech and get advice . There's place for analog gauges like when diagnosing a TXV that is hunting or setting the cut in and cut out on a refrigeration system,. Other than that I don't really see the need for them.

Always put refrigerant that’s in the hoses back in through suction side to prevent refrigerant loss. Or use pressure fishes with no hoses to check, this will prevent it also 👍

Fieldpiece smart probes would fix this issue :) Or any type that does the same thing without hoses.

What ??

Most of the customers we serviced when i was at this company had energy management services. we often would contact that service to force all the units on so that we could check operation. Also, some EMS companies will allow you access via app on your phone so that you may cycle on and all stages of heating and cooling. In larger supermarket operation, you will have EMS units such as Danfoss, E2, Novar etc that your able to graph and read logs that give you alot of important information. Most PM's are set at a low cost to the customer or they are not charged. This allows the contractor to service a customer and produce found on work. Meaning, if you show up, run the unit and find the Condenser fan motor not running, you would quote it out. Every customer has different rules especially with large Box stores and large retail chains. I always recommend for everyone to understand your companies goals and processes. understand the customers contract so that you can play within their rules. be very descriptive with your information and detail your report with high accuracy. take tons of photos this way you can show your customers exactly what they need and build that trust with you and your work. best of luck hope you found this to be helpful.

If the fan is moving too slow the motor itself could be failing as well. But we could ignore all that, the speed youre seeing isn't accurate due to frame rates. Can even hear how choppy it is in the audio.

belt tension tool is the proper way. amp draw will tell you a lot of other things though.

@@Fryloc87HVAC belt tension tool will set the belt's deflection. amp draw will tell you the motor's performance at any given deflection. check with the manufacturer. don't take my word. the manufacturer will provide the required specifications.

some motor you can't reach especially with the door off, safer not to put your hands where there are moving part regardless of what the manufacture says. they don't pay you for workman comp, some of the customers dictated where they want this done. Thanks for your input.

If the amp draw is good, and the belt is flopping like a fish, what are you going to do, leave it? Don't be a hack. If the amp draw is good, you may improve it by adjusting the belt properly, and that would be a job well done.

@@petersplat6164 the amp draw would never be ok with a flopping belt. amp draw and belt tension are one and the same. check the manufacturer's specification.

@k bone amp draw take a few seconds

Thank you for the question. For the most part a Basic AC unit, split system or a package unit is usually operates in the same manner with same or similar components. Some manufactures may have some complex electronics, Variable speed drives or de humidification that may be a bit more advanced. Overall, you work on a few at the start of your career and they become easier. Attend seminars that manufactures have, this helps you in some ways understand and also gives you the opportunity to ask questions. My main type of work is supermarket refrigeration, i will be posting some vids soon.

@@JulianPardenilla i jumped the gun and decided to get my epa licenses took two tries but i got universal and enrolled in a hvac trade tech school program my city has. really want to apprentice

@@JulianPardenilla how does the whole union thing work. never joined one out of stupidity on my part. i want to make as much as possible and get as far as a can because i have every intention to submerge my time and money on getting set up. im only getting older and my kids are too ya know how that goes

I always check pressures just because ive seen some units with a 20° differential between return and supply,,, but with a higher than normal head pressure and superheat, usually causing a higher amp draw as well,, caused by either a restriction in the metering device or in the filter drier.. either way its just good to always check

Great points you make Nathan, unfortunately the average new tech struggles enough to understand super-heat or Sub-cooling or even read a PT chart. the S-man and other similar digital gauges are great to use, but when the simple things such as cleaning coil or identifying how to test a unit are missed by your average PM guy, The S-man may be a bit too much tool for him or her. As i get the opportunity to create more content, we will definitionally use more advanced tool on things like start up where they can be really useful.

Why would u check Subcool or superheat on a Maintenance package unit call unless u suspect problems.

His nickname is tasty lemons

Depends on the season. In the spring, for sure. In the winter, not as much.

@@johnstewart2767 I've never once in my life done a coil cleaning when doing a PM 🤷🏼‍♂️. Here in New York City those are two different jobs.

I would have hit the drain regardless of pan condition.

I'm going to HVAC school this fall. I think it'll be worth it. you have to go all in bro if you're going to do it!!!

im 35 with a nine year old, no job at the moment, already 23+ hrs into the 600 hr. course . will be done in 5 3/4 months. Just get it done. Sacrifice now to have a job paying 30+an hour later.

Rick Rodriguez bro so am I. I’m 24. School starts next week aug 19th. I’m excited. I’m doin pm classes

I would ask a plumber personally but it depends on what you want to tolerate as far as hours and outside weather. It's more than $30 an hour....

plumbers have to deal with poopy water on the regular lol. keep that in mind. HVAC has been good to me so far (4 yrs)

You certainly can, having proper pressures and knowing your ambient you can do the math without having to check every single unit.

Thank you for your feedback, Time is of the e sense on a PM. It is definitely a point worth making but for the sake of time we did not cover this on this video. we will discuss this on larger units such as build ups on a three, four or five groove pulley with larger turbines such as forward curve blowers etc.

Perhaps, but how much stretch & stress was inflicted on the drive belt by installing with that method? And by how much does it really shorten its life? There is no way a technician will have time to loosen every motor. These drive belts are manufactured to sustain such stress before fully failing
