Man you have helped me tremendously! Been doing this almost a year and I understand a lot of it coming from mechanical industry. your videos help me absorb the hard concepts like this. Doing furnaces in the winter is cake but ac is a wild animal. Thank you for sharing your knowledge!
❤❤❤❤🎉
Top notch as always. Ty
Can you please create a video on charging a R410A package unit with a fixed metering device ? There’s not a single video out there that I can find out there.
So when you have say 2.5 ton outdoor and 3 ton indoor coil. Is there any point to knowing what the indoor coil size is?
Thanks, Craig! Currently learning how to service condenser units in school and this helps a ton!! Appreciate everything you do!
Problem 5 is kinda tough because it's a possibility you still wouldn't realize it's a restriction.
Best explanation of real world scenarios and descriptions here. I’ve been in this trade a little over 8 years, the last 5 90% service. The legit pages like yours helped me understand this broad trade not only quicker but much more clear. Up and coming new techs installers, or experienced ones, listen to this Man! One of the Best instructors out there and he’s delivering it all for free. I’d say most of us only work so we can make some dang money, and the more knowledge you have, the more you’ll make.
Thank you for the continuous content!’
It is a real pleasure listening to your concise/thorough explanations for each topic you cover and how you tie each relevant piece together. Keep up the great work and videos
Great video. Thank you for sharing. Have a nice weekend. May I ask, How about Heat Pump in Heat mode in the winter, How to check for ? is it the same or different. I love to watch your video ^_^
Has anyone had used the ebook E-Book – Refrigerant Charging and Service Procedures for Air Conditioning. I'm new to the hvac field and trying to learn as much as possible. Just curious if this would be a good reference material.
Something to add for the new guys…. If u run into an EEV system with a single stage outdoor unit (ie tam9 with XR condenser) do not assume it’s low when you start it up and see 80 psi suction, give the valve and sensors some time to do their thing.
On hard to diagnose systems,
I like to Reclaim and charge system to a calculated weigh in charge.
That way you have a reliable base line to work from.
Don't worry about drift on 410 it's negligible

For problem four, don't forget check your coils Dirty coils will increase your head pressure
This is why having a big air system is pointless. Spell a short cycle. And you're not gonna be removing any humidity from the air every time I go to a house. Somebody's like, yeah, I got a bigger unit. I'm like that's not better, that's worse
As a technician of 27 years, I still love watching these videos and it's weird when I was just talking to one of my co. Workers who's trying to get into air conditioning. We had almost the same numbers on a unit on the roof and I questioned him on what could cause that.
And this brings me right to the point. If it's rainy and you're doing fresher intake and with no return. If you've got 60 to 65° outside there and you're not moving too much air across that coil. Because most of the supply registers are closed, you're gonna freeze. And it's amazing that within a few seconds of seeing the numbers on the gauge, I already knew what the problem was. It's like they always teach if you can see what's going on inside the unit in your head. You can add anything you want and take away any part you want. And it still makes no difference to your. Knowledge
we run our hvac to 60 on the thermostats we have 11 units a warehouse to keep wine chilled
We’ve been installing many variable speed compressor Heat Pump units to retrofit outdoor unit,while keeping existing indoor systems (mostly Carrier model MURA), and I personally think it’s a great move,given the low power consumption and favorable weather conditions (32F Winter/103F Summer min-max average).
We have to replace TXV on many of them… What’s your opinion on the changing conditions on pressure on the TXV’s operation. Do you think they can handle such ranges and be expected to be reliable on long term?
So far,so good. Just curious on your take on this subject.
And before commenteers start bombarding with “Why not change the hole thing?”
The simple answer is: The customer is not willing to make such investment at this time,and we are not in position to question their reasons,much less to tell them what to do for profit!
Another great video.👍
I needed this information, great video as always boss💪🏾🫡
Amazing video, well explained. No one makes better videos than you. Keep up the great work Craig!
Deel knowledg
You are truly a blessing Craig. Thank you so much for clearing this up. I ran into this problem just this week and it turned out to be low heat load. Thank you again.
Best One Yet !!!!!!
Please answer I'm waiting sir please please,🙏 If the boiling point of R22 gas is -40, then how does it convert from vapor to liquid in the condenser?
I’ve seen wild head pressures and subcool due to sensing bulbs secured on brazed joints or loosely.
When in doubt weigh it out. Jonny Cochran of HVAC. 🤘⚡️🤘✨✨✨
Great video as always 👍
