In a room, by yourself, mumbling through a mask. Seriously?

Parkour says:

Fixed orifice metering device

clementino francisco says:

This guy make everything so confusing, just not a great instructor for beginners on hvac

A/c Tech says:

Well explained👍👏

Adarsh jadhav says:

Mask should be wear at work of HVAC/R

Hello. Is "sub-cooled" refrigerant any refrigerant that is not in "superheat" state? Like is superheat a name for "vaporized refrigerant" and subcooled is another name for "liquid state refrigerant" could I think of it this way? or is it a mistake to think that way? Or does subcooling only entail the distance from the metering device into the evaporator coil until refrigerant flashes up into a vapor state superheat? Thank you.

RAC Monkey says:

Thank you so very much!!!!!!

Alejandro Lujan says:

Thank you for what you're doing, brother. You have been able to make a lot of clear sense in matters that my instructors haven't been well enough to illustrate to our classes. I'm green to this field as are the others in my classroom and you make more familiar what we have only read and discussed.
You're greatly appreciated

Peter Larsen says:

Terrific presentation and a great philosophy of having the students understand as much as they can to be better prepaired for jobs in the field. There used to be a philosophy of guarding information figuring that the younger ones would take their jobs or something.

Hart Dagogokalada says:

Great job and goog teaching I like it

armarra says:

Wasn't as clear as I'd have hoped but I persevered… watching it a few times.

I noticed you throw in incidental information which is good info but also detracts from the overall progress of your explanation. Having notes or putting up a list of things to go through in correct ORDER may help this apparently random collection of useful information.

I had to go outside your explanation to find out the terms subcooling superheat and saturated. I also note that the best piece of information you gave in the whole video was that we actually are interested vin temperature at the Centre of the two coils, but it's hard to access, so we gather that from the pressure readings on the lineset and convert to temperature. That is what made me understand..
Not trying to be overly critical bit the extras you put in are detracting from what you are trying to convey overall. Things like whether it's a tx valve or not and which is more efficient ..is good information but it sidetracked your flow of information and that loses our concentration.

awesome video! i love your channel thanks for this amazing information!!

Juan Resendiz says:

What a wonderful training class!

Zo says:

Thank you 🤝

Rick Man says:

You wearing a mask I assume you got the jab 💉 the HVAC way🧬👑

Frank Roper says:

I was trained the evaporator was supposed to be 50F. That was in the R22 days. 40F would be more like a car AC.
