Charging R-410A Refrigerant into an Air Conditioner! Pressures, Temps, Tips!

In this HVAC Training Video, I show the Step By Step Procedure for Charging R-410A Refrigerant into an Air Conditioner that is Low on Refrigerant. I show the Pressures, Temperatures, Delta T, Charging Methods, and What to Watch Out For when Adding Refrigerant into an Air Conditioner equipped with a Piston Metering Device. Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.

[@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.

For sure one of the best videos I have watched pertaining to filling with the why's and how's. This video has certainly left enough of an impression on me in regards to filling systems. I will admit that I have filled a little too fast in the past based on how low and slow you let the gas in. Thank you for your professionalism and explanation. I look forward to viewing more of your videos in the future.

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

[@CASTRO45ACP]

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!

[@waynebollentin989]

@@FalloutGenius1 the insurance isn’t that bad for a small HVAC company. It’s also a must if you want to be licensed in most states.

On the older r22 systems I usually went for 8° super heat where most systems preferred 12°. Never had a single complaint. The differential between return and supply Temps were preferably 14-21°. Anything less usually indicated a blocked evaporator coil.

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.

Great video

[@paulrozinski1488]

Another great video from Craig👍. Is this is a new method of bleeding air out of the manifold hoses?? I recall the first method where after connecting hoses to the valves, you loosen each hose at the manifold end. Is this new method better ??

[@imustbcrazy700]

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.
