Ty is such a great teacher and I'm so privileged to call him a friend. Make sure to check him out @love2hvac on all platforms! Also, make sure to check out the articles, quick tips, quizzes, and more at acservicetech.com . I appreciate everyone's support that you have shown us over the years! Thanks so much!
Thanks guys! I know it’s hard work producing these videos but the reward is how they help all the techs in the field and those just starting. I’m proud to support them with my Patreon account and I hope more viewers will do the same.
Good afternoon, Craig. Just finished your book Refrigerant Charging and Service Procedures for Air Conditioning . A great book. Thank you for all you do.👍👍👍👍👍👍👍.
Hey just wanted to leave a comment today. I’m a technician from FRESNO CALIFORNIA. I just wanted to thank you and Ty so much as you two alone have increase my knowledge and technical skills so much in the past two years I couldn’t be more grateful for you guys! Im sure a lot of young techs like me appreciate you guys!
It’s fun to see the two of you together. Both have different styles and personalities. However at the end of the day the knowledge and professionalism comes across clearly in your deliveries. You can see that you guys love what you do. I have watched many of your videos over the years and never once thought that the information was not correct. Anyone who has made a video knows how much work goes into making them. It’s not easy as it looks. Thanks.Roger
Excellent informative video guys, from a service tech that remembers when noone had a recovery machine/ tanks, no one purged nitrogen while brazing, no used or where there micron guages, some people didn't even have a vacuum pump, just purged. The way you knew you had a vacuum was by sound of the pump. The days that some some idiots blasted liquid R-12 onto a case of beer to rapidly chill. "Beer can cold?? Even though there is a lot of nonsense in our trade today, I still love doing it for over 30 years now. Hey.. How do you recover that refrigerant charge in that TXV bulb?? Ha ha.. Thanks for the video. Very good explanation for beginners and nice to see such exists for old timers like me that originally learned from really old timers / father that was in the business ;)
The txv cannot be used in normal ac systems you will need to have proper hp mechanism for the safety of the compressor for high pressure due to closing of the thx and you will need liquid storage tank which will increase the cost
@@topshelflifestyle01 Still on the start of the adaption S curve. Maybe once variable compressors are standard manufacturers will need a new top of the line offering.
Because engineers need projects to rationalize their pay. No "innovations" no engineer jobs. Just like a budget coordinator who cuts materials that are needed to prove their worth on a spreadsheet.
If you ask me, the less electronics and moving parts the better. I’ll take my piston any day. Just need regular maintenance and gas check to make sure superheat is correct. That’s my two cents.
Very informing video. Questions On a piston type metering divce, how the amount of refreegerant is control.what if there is too much or not enough refreegerant. what is the anvantage of this type over others. thanks'
It’s time to replace my 34 year old Rheem. I know it has a piston at the evaporator coil. And all these other metering devices seem to have a lot of moving parts. I would love to get 30 years of the next one, but everything is made like crap today.
Hey Craig! I have a question if you would be kind enough to answer.....In a single speed system with a txv, when the txv is constricting the potential flow to increase efficiency in the evaporator, does that raise the head pressure, reducing the efficiency in the compressor?
Did you read the manual ? Depending on manufacturer, line set sizes will vary by application. If outdoor unit is at or below indoor elevation, that size should be good but if your outdoor is above indoor elevation the line set size usually decreases in size to increase velocity so oil can make it back to compressor.
Good afternoon! I'm trying to understand if metering device is Piston or TXV for my Carrier evaporator Coil inside. The identification plate on the Carrier condenser unit outside lists: Piston 73 (Indoor) n/a (outdoor), Indoor TXV Sub Cooling = 14 degrees Fahrenheit. So, is it piston or TXV? I'm trying to figure this out without having to open up the Evap Coil. Thx
When the line set is long enough, cut it out after recovery. Its safer and in regard to the filter drier, you won't release the moisture back into the system by heating it.
I looked at an 5T Goodman install where the piston system an .083 on about a 75 ft lineset at about 17ft high, would run fine, but then the super heat would just start dropping from 11 to a 5. The system ran supposedly, but then started blowing the cooper tubing on the output side of the compressor. It would just explode the line off. Any ideas?
10:44 oil additive... brazing while not flowing nitrogen... so no soldering allowed... poe oil ...filter dryer ...how is the poe oil used in the compressor is it two different oils?!... how do you vacuum out oil etc... pistons seem the best with a single speed compressor...way more simple... jeez

I hope he keeps these videos up. I’ve learned so much in the 8 months I’ve been a service tech just from watching these videos
Good afternoon, Craig. Just finished your book Refrigerant Charging and Service Procedures for Air Conditioning . A great book. Thank you for all you do.👍👍👍👍👍👍👍.
Thats awesome!! Thanks Brian!!
my two favorite teachers in the same video, thanks you re the best

Thank you so much for your awesome encouragement Joseph!!
Great video. It's good to see two masters of the trade together instructing us.
Amazing presentation guys! Cheers to you both and your teams!! 👊😎👍💯🍻
Wow what a combo of knowledge! This is legendary

great video as always 7 years in the Trade got my Journeymans but still learning everyday
You guys are a perfect match for this trade. You both are my favorite teachers. Harmonious!!
Great video. Thanks for everything you guys do
Thank you so much for the great content that you are producing fir your channel. It helps to learn a ton to keep information fresh.
As always I like your video and when you’re together it makes better.
The two Goats of HVAC
Thanks for again sharing some very valuable information. Glad to see the collaboration between teachers. 👍👍👍
Thanks guys, this is awesome learning for a beginner like me 👍👍
The collaboration we needed.
You have got to love these two guys 😊.Great job
Fantastic
Loved the superheat explanation.
Watching and learning from Papua New Guinea
Thank you guys for the great video! Good stuff.
great presentation!
Love the videos. Please keep posting more!
Awesome video I've learned so much from both of your channels
Awesome! Thank you for watching me and Ty!
Thanks for the review and excellent commentary!
Very thorough explanation. Thank you!
Both are awesome teachers leaned alot
Great info. Thank you Craig and Ty.
Great Video. Thank you for sharing. Have A Nice Weekend
The txv cannot be used in normal ac systems you will need to have proper hp mechanism for the safety of the compressor for high pressure due to closing of the thx and you will need liquid storage tank which will increase the cost
Would love to see video on ac and refrigeration plants on a marine vessel/ship as they are always very tempremental
Soon enough turboexpanders will be the next expansion device. Electronically controlled and recovers energy from the pressure difference.
Too expensive, gonna be a long while. They r focusing on being cheap for now
@@topshelflifestyle01 Still on the start of the adaption S curve. Maybe once variable compressors are standard manufacturers will need a new top of the line offering.
As always, great class!
alot good information
Simply excellent, team.
Very nice video
Great explanation youguys did a great job
just amazing! Great Job guys
Thank so much all ideas both of you guy work great together 👍👍
I throughly enjoyed this thanks guys
Great video 😊
Great video, thanks for teaching 👍 🙏
Great video as always
Just what we need, another electronic device prone to electrical surge damage. The TXV works perfectly, why make everything more complicated?
Because engineers need projects to rationalize their pay. No "innovations" no engineer jobs. Just like a budget coordinator who cuts materials that are needed to prove their worth on a spreadsheet.
Great job! Extremely helpful!!
Glad you think so!
Nice
Awesome video, thanks very much!
Im trying to get a free copy of those books craig! 😅😉
Thank you so much. Bless you.
🇺🇸👍💪❄️ luv 2 learn. Thanks gentleman
Super thanks you guys
Extraordinario mil gracias
If you ask me, the less electronics and moving parts the better. I’ll take my piston any day. Just need regular maintenance and gas check to make sure superheat is correct. That’s my two cents.
I preferTXV or EEV.... much better and least problems
@@eduardocastroisaac1630 so do most in the business. I’m just sick of $500 circuit boards failing or shorting out
Very informing video.

Nice
Saturated temperature is before the metering device? Line temperature is after the metering device?
What is the legnth of the evaporator per distributor tubes going to suction line?
I have ONE question ❓
Can an Old Line set of 3/4, 3/8 on 2.5 ton System Change over to 3 ton System of Evaporator coil and a Condenser Unit ❓❓
It has no any problem. Actually 3/4, 3/8 pipe set is the right set for 3 ton unit
Did you read the manual ?
Depending on manufacturer, line set sizes will vary by application.
If outdoor unit is at or below indoor elevation, that size should be good but if your outdoor is above indoor elevation the line set size usually decreases in size to increase velocity so oil can make it back to compressor.

I'm trying to figure this out without having to open up the Evap Coil. Thx
do you guys recommend burning or cutting out major components?
When the line set is long enough, cut it out after recovery. Its safer and in regard to the filter drier, you won't release the moisture back into the system by heating it.
Can I used other txv for my 2.5 tons airhandler just hard to find
I looked at an 5T Goodman install where the piston system an .083 on about a 75 ft lineset at about 17ft high, would run fine, but then the super heat would just start dropping from 11 to a 5. The system ran supposedly, but then started blowing the cooper tubing on the output side of the compressor. It would just explode the line off. Any ideas?
I want to know temperature increase allow more refrigerant in evaporator and if pressure increase allow more refrigerant in evaporator.
👍👍
So the piston has replaced the capillary tube and the EEV is the modern version of the AEV
Figures my filter dryer is outside and close to the ground and rusty as can be.
Why is it an EEV not EXV?
This
No cylinder unloaders or slide valves?
Just kidding! 😅
Please Hindi language channel sir
10:44 oil additive... brazing while not flowing nitrogen... so no soldering allowed... poe oil ...filter dryer ...how is the poe oil used in the compressor is it two different oils?!... how do you vacuum out oil etc... pistons seem the best with a single speed compressor...way more simple... jeez
Automotive industry just does not have this level of education both in quality and quantity.
Great video!
