I'm glad your taking your time to teach the guys coming up in the trade. I never got that. One time I asked an owner about training. His respones was who needs training, don't you know what your doing. I asked another owner and his response was we don;t have time for training. That company had a 75 percent call back rate. Great for making overtime.
@@SuperVstech Trained owners to do what.?. I leaving the HVAC business. Just not worth it any more. Too much BS . I can take a 15 dollar minimum wage job not have nearly as much stress .
@@johnd4348 you would be surprised at the amount of owners who don't actually know theory or design principles, let alone how to operate a business. For the record, I agree with you: starting up a small business right now would be an incredible amount of stress.
Excellent class! I like how the instructor engages with the students and asks why. It forces them to think and formulate an answer in their head, whether or not it is correct. This feed back is important to the instructor as to how well the students are absorbing the material. Also consider that people are much more likely to remember mistakes in thought or action and therefore correct their actions in the future.
This was a great refresher class, been a minute since I have seen a solenoid valve, or especially crank case heater.... Working hvac back in the 90s by Palm Springs California I suspected possibly one of the stupidest things to put on an air handler was that crankcase heater. Outdoor temp 115 in the shade... the rtu will melt plastic on tools.... funny, almost all the crankcase heaters were burned out... possibly they hooked them up wrong... I don't remember seeing any wired across the contactor... most were line and a few on the load side😂. Makes sense the way you explain it.
This is fantastic informatio! Now I know why I was replacing all those after markets hard starts on the Trane recips with OEM and they were working! Thank you
Great class. Thank you! But when are we going to learn about burying the linesets? 😄 Thats an interesting topic I am in Canada and everybody says that it is not allowed. What I read in manufacturers bulletins, they are also against it, but I see that in Florida everybody is burying them 😄 it would be great to hear your experience of burying them and how to prevent flooding.
Your videos are great and very informative. I use them to prepare to train our new service techs. Really appreciated the Power In The Blood hymn reference. "Wonder working pow'r"
That was interesting, entertaining, informative and fun. Now a question that may seem odd to a proper tech. What keeps the liquid out of the compressor during a power-on reversal like entering defrost mode? Probably stupid obvious to most but I don't know.
Brian, Not a tech but Im trying to learn more about capacitors and you answered a lot, but i still have questions. In short, put a universal condenser fan motor and matched dual capacitor on a trane with running but too noisy, fan motor, it started and ran but it seemed to be not up to full speed and had a pulse feeling vibration. Ended up calling a local tech and he installed an additional run capacitor (small one) and it ran great . What should i have measured or looked for to have known this. This unit at daughter's house in Ga. And Im back in Tx now. Thanks and these vidios are very informative, great job
Brian, thanks for the information. You mentioned that you would offer advice on how to bury line set, if necessary. I understand the potential for condensation but in my case there is no option but to bury for approximately 35 ft. The install in in North Florida (Jacksonville area). Advice please on how to do this while minimize condensation
I was told by D&L to remove the relay & direct wire a hard start straight on a fairly new 2 ton Goodman heatpump.. that a previous tech had started removing parts & he thought the factory hard start was a special run capacitor... it sat for 8 months.. I figured out the entire reason it wouldn't run was because it had 0 refrigerant in the system. He'd melted both Schrader valves & it leaked out.. 😅
Ya missed a test. The crank case heater not only heats via the band, it also pulls watts through the compressor windings, and the motor windings ALSO produce a small amount of heat. Ya can measure the milliamperes on the common winding.
I like how energy kalo hes free in spirit like how he can joke with his classmates when I'm teaching I'm tend to sometimes do things wrong but not Ina manner that I can go back from like for instances for getting to put the flex seal on the cooper line before soldering so that the tech can only see what I gave to go through cutting ✂️ open to only make it look like I never cut it so he sees that it's ok forget but so he won't have too if I make sense !!!.
Your guy asked why wire the solenoid on the y call, not on the O call. I hope you answer him… most thermostats energize the O terminal when in heat mode, the entire season, the valve would remain open.
So why can we do that when we have a 5/16" line over a 1/4"? Finger over a straw principal been actually locked out liquid in liquid line in a substantial enough amount to adequately feed the TXV and have totally superheated gas By the timer on the way back from the evaporator to the condensing compressor

as far as 1/4" lines, u use larger to reuse line sets with higher efficiency in the future... line sets are the largest fee wen replacement is needed... change outs are easy. same applies to your low voltage rough imo.
@@HVACS we are not going to communicate in that way. Lets address each other with out the sarcasm please. Is that ok with you? ( referring to you mindset video)
Teachers who constantly (ask the class why?) (who can tell me ? ) is such a bad method and flow. It causes students to mind wander and decreases participation. Only the me,me,me guy will always answer. Just teach the goods.
Encouraging discussion and allowing for active thinking in the class is much more effective than lecturing. I am an HVAC trainer and this is exactly how I conduct my classes. Notice that Brian occasionally pointed his questions at students that hadn't answered yet to encourage the whole class to participate. When it's an impromptu class like this without preparation on the part of the students, it's necessary to actively involve them in the learning process.
Thanks Brian!!! I’ve learned a lot by watching your videos

What can we do to prevent having problems with a buried pipe?
yes please

love this class thank you
Thanks for discussing problem and doing training. It is going to change again with new A2L's coming next year. (Long lines may disapear)
After he said "if you have a 1/4" line and a txv.." I was instantly ready for "You might be a redneck"

Tremendous class I loved it
dude, you're a God! Hella funny, too.
I never clicked so fast on a UA-cam video :D
I thought this was about fishing. We use to long line in the Ocean.
So what if we don’t have a sight glass for long line as a visual will sub cooling be still accurate for a 120+ feet of line to go by ?
short answer: no
install a solenoid in a "buried line situation" and ur fine
nice vid, liquid is a compressors enemy, just the same as overtemp.
hey great information. the literature you read from where can i get from?
Great video!
Great videos 😜
Is there more room in your class ?
Where's Aaron?
What is the weakness of piston of metering device?
None, they work but not "efficient "
High seer unit with low ambient = ice up's. Txv's has a wide range of operations to compensate for external factors.
@@airmech5083 high seer unit wouldn't have a piston.(shouldn't)
@@realestateservicessaleshea99 if the txv is a separate purchase, most guys go with the factory supplied metering device (piston).
A piston metering device has no variability.
Omg a shovel? 😀

But we must charge in liquid 😶
as far as 1/4" lines, u use larger to reuse line sets with higher efficiency in the future... line sets are the largest fee wen replacement is needed... change outs are easy. same applies to your low voltage rough imo.
simple way to look at it: what do u need to do to replace a 10 seer with a 16 seer, 2 stage or better?
a change out is cheap if they have 7/8 3/8 and 8wire low voltage, no?
now, consider what most builders have roughed... lol
