@@goodvibes04281 I'm 35 myself and I'm still considering. I signed up for a couple job interviews that I hopefully get. From what I heard the types of AC units are changing nowadays so we might be learning new stuff.
im 15 and learning about hvac for a good summer job to get a car and this video helped me a lot, a took about two pages of notes and just wanted to thank you for this
Remember, you can't please everyone. In big office buildings, you'd be amazed at how many people complain about the temp on a daily basis. It'll be 72 in the office and half the people are "freezing" while the other half is "dying" of heat exhaustion.
I previously worked with a finish millwork company and then moved on to a General Contractor, MEPS are super new for me and this helps ALOT. Thank you!
The animated video presentation on basics of hvac has been excellent. All basic components have been spelled very easily for the beginner to understand clearly. This will inspire individuals to make their career in this field. Great going...👍😊
This is how I feel. I'm 26 and now looking into trades and bettering my life rather than work a factory job forever. I should have done this when I was 18
Basic questions about you, then why HVAC? If the manager told you your pay will delay what’s your reaction? How long will you stay? What do you see yourself in 5 years? By the way they have long list I’m still on waitlist when they approved me I was 76 on the list. Basically don’t quite what you doing.
I think there's a denotation error in this. Air Handler is the name of the unit(AHU) that regulates and circulates air as part of a HVAC system. In the video, the unit shown is a Rooftop Unit(RTU ) which is a simpler, commercial type of AHU. The part they call air handler is called fan/blower and it may be inline centrifugal or axial.
Thanks, very basic and useful for general purposes for public. It would be a good if do same idea of animation but for higher experienced professionals... like, cfm calculations , SST temperature, DST, temperature, capacity calculations, coil geometry... Thanks
What affects the productivity and morale of the tech is dealing with the occupants that are hard to please no matter what you do or how perfect the system is operating. 'Nature of the beast.'
they constantly complain that their aircon is too hot/cold, while we have to work outside on that condenser blowing out like 40c air. To be honest they dont have to right to complain. especially when they have those pesky little electric heaters they have brought from home sitting under a return grill. and they wonder why they are getting nice 12c air in the middle of winter
sorry sir your ac is working just fine but I can recommend a tampon for you .... or the blower is to loud or one room doesn't feel the same temperature as the others then u change the dampers to flow more to that room then check the CFM,s still complain

It is very ancient, but very simple direct evaporative air cooling with limited Temperature difference and added moisture to the product air. More advanced is indirect evaporative with dry and wet channels, wet bulb limit and dry product air. The ultimate tech is dew-point indirect evaporative air cooling inspired by Nature and implemented via advanced tech with multifold savings in energy and water consumption, carbon emissions and cost. Prototypes of the ultimate third generation Gen3 are already available for demonstration to all interested parties We would be happy to provide Undecided and Matt Ferrell additional information and demonstration video of prototypes with EER 200 (!)
I am referring and clear articulate Dew-point indirect regenerative water evaporative cooling and refrigeration. Persian Badgir or Egyptian Malqaf (windcatchers) are in fact swamp, or dessert coolers using direct evaporative cooling with 5-10 deg. C temperature difference and added moisture to product air. M-Cycle is principally different with dew-point temperature (the hotter ambient - colder product) and no moisture added in product air and no air recirculation. M-Cycle works unassisted up to 18-20 gram per kg of air Absolute humidity, not RH% regardless raising ambient temperature.

I really messed up on a great opportunity from my community college and high school Last year grade 10th high school sophomore I was granted a Free tuition into the college and, could pick any trade i wanted to learn and IMMEDIATELY start working after high school with certifications already under my name. My 10th grade self did not take this opportunity as seriously as it should’ve been and wanted to “spend more time with friends” This quarantine really opened my mind into After high school i would probably Never see them again
One thing you'll learn is there will always be decisions we look back on and wish to have done it better or different, but if you have the drive and the means, it's never too late to start something new. This is coming from a 30 year old that's starting my journey into HVAC hopefully within this year. Sometimes your journey has (un)intentional detours
One of the reasons of climbing temperatures and climate change is conventional HVAC industry. The next R&D stage of the HVAC climate-friendly transition is a step forward from Low GWP to Zero GWP refrigerant. Water is absolutely zero GWP refrigerant. Dew-point indirect regenerative water evaporative cooling and refrigeration can substitute a traditional AC with drastic reduction - 15X in energy consumption, 20X in carbon emission and 5-7X in capex and opex cost. Lower energy consumption of air cooling - more affordable overheat relief and tackling climate change. 5X greener AC was a dream of The Global Cooling Challenge 5 yrs ago. Now there is a 10X greener (water) evaporative prototype.

They also have U.V system
I really messed up on a great opportunity from my community college and high school
Last year grade 10th high school sophomore
I was granted a Free tuition into the college and, could pick any trade i wanted to learn and IMMEDIATELY start working after high school with certifications already under my name.
My 10th grade self did not take this opportunity as seriously as it should’ve been and wanted to “spend more time with friends”
This quarantine really opened my mind into
After high school i would probably Never see them again

One thing you'll learn is there will always be decisions we look back on and wish to have done it better or different, but if you have the drive and the means, it's never too late to start something new. This is coming from a 30 year old that's starting my journey into HVAC hopefully within this year. Sometimes your journey has (un)intentional detours
One of the reasons of climbing temperatures and climate change is conventional HVAC industry. The next R&D stage of the HVAC climate-friendly transition is a step forward from Low GWP to Zero GWP refrigerant. Water is absolutely zero GWP refrigerant. Dew-point indirect regenerative water evaporative cooling and refrigeration can substitute a traditional AC with drastic reduction - 15X in energy consumption, 20X in carbon emission and 5-7X in capex and opex cost. Lower energy consumption of air cooling - more affordable overheat relief and tackling climate change.
5X greener AC was a dream of The Global Cooling Challenge 5 yrs ago. Now there is a 10X greener (water) evaporative prototype.
You are referring to a swamp cooler which is only good in very dry climates.
Arizona or Texas etc, etc. Not in places with the humidity is up over 45%
@@scottchapman9931 No, I am referring and clear articulate Dew-point indirect regenerative water evaporative cooling and refrigeration.
Persian Badgir or Egyptian Malqaf (windcatchers) are in fact swamp, or dessert coolers using direct evaporative cooling with 5-10 deg. C temperature difference and added moisture to product air.
M-Cycle is principally different with dew-point temperature (the hotter ambient - colder product) and no moisture added in product air and no air recirculation. M-Cycle works unassisted up to 18-20 gram per kg of air Absolute humidity, not RH% regardless raising ambient temperature.
How bout I’m here because I wanna get into the HVAC/R field only to realize this is a sales video 🤣😂

Excelente otro excelente trabajo
2020: lol offices? So last century
They kind of ar. Many high rise buildings have opted to rent out their space as storage units, mainly for old file cabinets that have paper records and other office equipment.
Good stuff. Thank you for sharing.
