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.

All of these videos are so informative and detailed its like being in the classroom. Anybody else here in hvac school watching these to teach themselves?

[juniotgalyen]

I've been doing hvac for over 40 yrs you doing a great job on your videos.

This man knows what he’s talking about! Respect!

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.

I like how you cut off the yellow hose filled with liquid refrigerant early and allowed it to finish charging the system. What attention to detail! I love your clarity. You are a true friend! Thank you for all of your hard work!

[c.p.h.]

Great video! Im a 1st yr 2nd semester refrigeration student starting from scratch....this video is priceless....👍🏾 THANK YOU!

[jimbonito]

You are a great A/C tech . If there was young apprentice wanting to learn the A/C biz you would be the guy I would want as an instructor ... Kudos to you and your expertise

[albyone]

I watched videos from several other 'folks', and read many articles. I have to say, your video is by far the best available, light years ahead of everyone else. You explained not only the how, but the why, in simple terms. If you were living in my area, I'd hire you in a heartbeat!!! I'll subscribe and buy the book to support your site. Keep up the great work!

[JustinRamtime]

This was a great video! Helped me out alot...my instructors from Institute of technology HVAC sucked....didn't have the patience to instruct accurately cutting corners is what I see from them. Thank you Sir for the lesson.

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.

Great video ! I'm a retired HVACR tech and it's nice to view your vids to keep me in the loop of HVAC

[VooDooWarrior]

Best explanation I’ve seen on the internet with usage of tools, temps gauges and charts ty your a lifesaver! This is a field I’ve been interested in for a very long time. My son is also liking it!

[Twilightzoneisreal]

New subscriber. I went to tech school back in '99 and worked for Sears and a couple of other companies until getting hurt and had to quit. These videos help keep me sharp because everyone knows that if you don't use it you lose it. Thanks so much!!! Well done.

[johnerway]

Super job showing the correct use of sub cooling and super heat application. Thanks

[chrisbiohazard]

Thanks for uploading this video. For the community.

[anonymousmeme]

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.

[johnmartin]

Your a great teacher and a hellofa expert at explaining how it is done at your level. Thank you and right on brother.

[gingersnap]

This guy Def knows what he's upta. Gunna show all this to the trainees

[brianl]

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.

Sir your higher than a pioneer!! Superb job!!
