Ive been wanting to join this industry for quite some time now. I recently graduated a HVAC/R Technology Diploma Program and due to covid I really didn't get the hands on training needed. So my company has me doing PMs to learn the equipment and finding issues. I hope this is a great way to learn. I've been told so many different things I don't know what to believe. So, With that, I Just ordered the quick reference cards and can't wait to use them. I am 34 and hoping I have a long career in this industry and get the hands on training that I need to be successful.

[@axeldread2979]

Kyle, depending on your state, it be might be possible for you to start your own HVAC business by getting your own insurance and getting a license from your state to be an HVAC Contractor. Different states have different requirements so if you really want to do HVAC and not fight the hassle of where you are at, then find a small town with no HVAC company nearby in a small business friendly state and put your knowledge to the test. It’s very freeing and there are plenty of distributors who will give you a dealership as well as online companies that will ship the products you need.

[@FalloutGenius1]

@@axeldread2979 the insurance is what will kill your profits, not saying it’s unnecessary but it is what prevents many from going into business for themselves

36 here and a 14 year plumber and have been doing HVAC for about 9 months now and honestly PM is where it’s at for guys our age, installs aren’t exactly what you want to be getting into unless you’re doing them for yourself, if your employer has a good set up for you to earn some commission then PM can definitely make you some good money if you work for a company that is doing commission for coil cleaning, system cleanings and selling new systems to customers you find with old systems that are shot, also some companies will pay you commission for good reviews on google and stuff like that, if you can find a place like that then you’ll make decent money and not kill yourself and honestly most installers just know how to lay duct work down and make everything look pretty if all they’ve ever done is install while with doing PM you’ll learn the ins and outs, good luck!

[@onemoremisfit]

Great video, very instructive and clear. The locking service port caps are interesting. I'm a DIY hack who installed my own system 24 years ago and it's still running strong (knock wood). About 20 odd years ago I had a friend call me on a hot July 4th weekend. He had family over from out of town for the holiday, a house full of people and his A/C failed. He called me and told me he tried to get a repairman but none he could reach would come until after the holiday. So I went over there with my gauges, vacuum pump and a tank of R-22. When I put the gauges on it there was no refrigerant in it at all. So we went along the line set to look for a leak, and there was no evidence of damage to it. So I put the vacuum pump on it and and tested to see if it would hold vacuum and it did. So I ran the vacuum on it for and hour and recharged it with refrigerant. It ran fine and I was the hero of the day. I told him if the charge ran down again he'd need to call somebody to track down the leak, but it never did run down. I checked with him years later and he said the system was still working fine, no complaints. They sold and moved about 10 years after and never had any trouble with the A/C during the remaining time they lived there. The house was in a semi rural area with the condensing unit at the rear of the house, and no chance of random traffic thru the fenced backyard. However there were several kids there between his own and their cousins. The moral of the story is the locking service port caps are a good idea if you have kids.

Absolutely excellent tutorial. Ordered your quick charts because of how happy I was with your explanations. I do have a question though, what’s the best way to determine if a system is using a fixed or Txv application? Thnx

[@sonnym9905]

Look on the manufacturer's plate on the condenser outside. If it says something like "TXV Subcooling 12," then it has a TXV. If you cannot find that stated anywhere on the plate, then you don't have a TXV.

[@DerrickTemp]

Thank you for a very informative lectures.

[@basspig]

This is a very interesting scientific method of measuring the system performance and the actual charge required to obtain optimum. But I wonder if simply filling it to the manufacturer's pressure specifications is also close enough for as they say government work?

[@w0lvez1]

Refrigerants are charged by weight from the factory. Most manufacturers recommend replacing the refrigerant when a leak occurred on R410A because it's a 50/50 mixed R125 and R32 refrigerant. On a car, it's completely normal to be low in refrigerant after 15-20 years because of the hose but not on a window and split type AC that uses all metal pipes. Low in Refrigerant simply means there is a leak. Very difficult to find a leak on R410A because it only leaks when pressure is very high. That is why the pressure test is done at 500 psi. It's probably leaking on the flare connection because 410A requires wider flare. No wonder why AC techs are so incompetent. They made their own procedure instead of reading the instruction manual.

[@warrenalbert9336]

This is great when yur house is at 71 degress and also outside. But I wish youd do this with temps like we have here with 113 outside and 79 inside. Im sure the numbers would be off the charts. we exect to get over 117 in a couple of days. Yes here in the phoenix area.

[@MarkSlusher-d1r]

Thanks! Just saved me a whole lot of money.

[@johnnyboy7881]

Question for you. Could you keep the 410 - A bottle upright and get only gas into the system instead of charging with the bottle upside down and getting liquid?

[@David_Mash]

No, apparently 410a is made of two different refrigerants and in the liquid form, they will remain mixed correctly. The gas above can be more of one refrigerant than the other.

So you must add 401a as a liquid? Because it is actually a mix of two different refrigerants that of course have different expansion temperatures, so if you boil off directly from the bottle one of the refrigerants will boil off first causing a concentration of that refrigerant in the released gas/vapor.??? Kind of like a distillation tower.

The worst air bleeding technique I've ever seen .

[@MyWORDisntGospel]

I actually started bleeding it the way he does a few years ago. To me, it’s the best way to do it. I was taught to bleed them at the manifold. I think that’s the worst way to do it. 1) oily manifold. 2) I always felt there was still air in the manifold that didn’t bleed out. Doing it his way (which he takes a long winded way of explaining) you get all the air out and stop oil from getting all over your gauges.
