I've discovered that it's never too late for almost anything. I was almost 55 years old when I started doing drywall work, which led me to wall construction, electricity and plumbing. I had never done any construction work before that. Since then, I've taken a course on solar system installation, free at a local adult school in my county. I've also learned sewing machine repair from KZfaq videos -- I was recovering from what I believe was a spider bite in my left foot, which was terribly painful for about 6 months. So, I was confined to the inside of my home. Right now I am learning everything I can on grammar and vocabulary, while learning touch typing and MS Word. Next projects are Adobe Photoshop and Adobe Premiere and, further down the road learn to play the harmonica. The way I look at things is that it would almost be a sin and a crime to waste all of this new technology, and all of this virtually free information. 68 years old and still wanting to learn and know more.

@ronaldhaefner8515 3 жыл бұрын

Spot on video. Not that it is hard to remember but an old refrigeration tech taught me years ago it is the direction of flow, the suction temp coming to the unit and then the suction pressure at the compressor. Then the pressure exiting the compressor then the temperature of the discharge line of the unit. Absorb heat is superheat and condensing is super cooling. Kinda quirky but helped me to remember the order.

@bertellijustin6376 Жыл бұрын

For me it was what I call the rule of opposites. High pressure high temp you check sub cooling, cold is the opposite of hot. (If cold was an actual thing) For the low pressure/cold side we check super heat, same reason. Not sure why but that’s how I got it to stick in my mind.

@randymoreno9345 3 жыл бұрын

I know this an old question but ill attempt to answer it for anyone reading this in the future. Refrigerant pressure is directly related to temperature. There isn't an average pressure that you're refrigerant should be. Provided that the system is properly charged and no issues exist, your "high" pressure will be affected by your outdoor ambient temperature and you "low" pressure will be affected by you indoor space temperature. All refrigerants run at different pressures, some very similar to others.

This calculator is for split systems to determine the additional weight of refrigerant needed within a system. If a unit comes with enough refrigerant for 15' of line set but you used 50 feet then you need to add enough refrigerant for the additional 35 ft of liquid tubing and large vapor tubing to determine the amount of refrigerant weight, thanks!

Many seldom think about the accuracy of their pressure gauges or temperature measurements. Gauges can be bought with specs from +/- 0.1% to over +/- 1% accuracy. Cost of gauges is usually in relation to their accuracy. 1% accuracy is about +/- 3 psia at high side pressures. That translates to about +/- 1 deg F uncertainty in vapor temp. Thermocouples of K type (yellow) have an accuracy of about +/- 4 degs F for typical air conditioner temp ranges. Thermocouples of T type (blue) have an accuracy of about +/- 2 deg F for typical air conditioner temp ranges. If thermocouple meter can change its thermocouple type setting, it is better to use the blue T type thermocouple versus the commonly used yellow K type thermocouples. All this is before user errors induced by reading gauge scale off angle making reading a little high or low from angle between needle pointer and scale, and. not providing a good thermal connection between thermocouple and copper tubing due to dirt and corrosion of tubing. Think about this when unit specs a subcooling range of 8 to 12 degs F and your test equipment cumulative temp/pressure reading accuracy is +/- 5 degs F.

Hey Craig! I'm a Senior in HS and i came across a positive video about your HVAC book! So next summer or so i plan to enroll into a HVAC program at a local trade school and i'm wondering if your book gives a person a pretty good overview of the basics and whatnot of HVAC. Cause i don't prefer going into trade school next summer being that guy that knows nothing. I kinda want to at least have a basic grasp of what stuff is/does,etc. Also, about trades school, how would you know if a program is a good or bad one? I know i won't enroll in one until next summer but what are some red flags i should look for when researching the schools or what questions should i ask the trade schools? Thanks!

Good point kid. The book is worth every penny. Get the whole package if you can. Book, workbook, and flash cards. Go ahead and get your EPA 608 certification (Universal card) while you're at it. It will give you a lot more than the basics.

@jamesortolano3983 3 жыл бұрын

Great question. Red flags are everywhere,not possible to know if your going in green. My advice ,like I tell most people who are mechanically inclined. Set your self up with 5 questions you want to know the answers too. Ie:what is air flow,how do we measure it,how does this apply to a/c operation. What is this closed loop system,how can we achieve it,how many items are involved. I had no school ,or internet,but I'm old . The old guy I learned from said this to me , learn the name of all your parts,learn the function they need to do .Ask many questions. When i get a new helper,and he is continuously curious,with question and trying to explain to me how he's thinks it should work. I know he's on the right direction. I'm still learning!! You'll get it!! Don't get distracted by the red flags,as this applys to techs as well. We just call them HACKS. KEEP interest in it ,and you will find the answers! I raised 3 kids ,nd a wife that never had a paying job. I started right where you are now . It's a great ride!! This field needs you !!

I am trying to learn how to fix my fridge and a/c by myself. These HVAC guys are blood sucking low life leeches. They want $850 to fix a pin hole leak on the copper pipe and recharge the gas when the fridge is $3800 brand new and $500 second hand. Simply cut and weld a new piece of copper pipe which can be done in 2-30mins plus recharge and testing, I am looking at 1.5hrs labour here. Good video thx!

I got the e-book. downloaded to iPhone and got garbage. It just does not work in the iPhone at all. I tried in a Windows computer and I have to install Adobe Digital Editions. I can see it but no way to resize letter, no way to search. That is not what is advertised. No way to get help from a human being either. Any comments?

Dude did you start the video in the middle or is this a continuation of a previous video?

@acservicetechchannel 3 жыл бұрын

You can check this video out which may help but no that starts out with the standard refrigerant bottle and going over pressures and temps. Here is another- kzfaq.info/get/bejne/fLGpeth5sLuyoKM.html

As knowledgeable as you are, you are not a good enough teacher yet. You go too fast and you leave out fundamental facts about what you are trying to teach leaving students like myself wondering what you mean. Is the system running or not is one of the one's you leave out quite often for us beginners. That being said...I trust your knowledge which is a huge plus. Slow down and pre-state the conditions we're starting with each time and you'll be the best teacher on KZfaq. I should know, I was, before I retired, the best local HS math teacher...and even the best salesperson when I did that. On a different note, I bought at auction a Snap-On R-12 service machine. Did they recover refrigerant in those days? It will apparently vacuum out a system, but it doesn't appear to collect the refrigerant. Can I modify it to do so? Thank you sir.
