man u teach me some good stuff! im gettin better by the video! this just helped me figure a problem out. i was thinking why the the equipment come with 7/8 stub and somebody reduced to 3/4 on a 25’ line set so i started looking for legitimate answers. i never under mind the hvac engineers and thats just what this installer did to my customer! i sure its what they had on the truck and knew better. bottom line not dumb just lazy!
Very Awesome, I have been following your instructions and guide lines. Very accurate, thank you for your professional guidance. Love your professional guidance!!!!
Read the manufacturer’s literature. For example, Rheem/Ruud 5-ton RP14AZ and RP15AZ heat pumps use 3/4” or 7/8” vapor lines depending on length, never 1 1/8”, and warn against oversizing.
Hi, quick question.. lets say you are replacing outdoor condensor unit, and if the existing vapor and liquid line length is not enough(assume0.. what kind of connector you use .. in plumbing we use 90 degree elbow etc.. i am not sure what will be used in HVAC just to extend the line by a feet or two. apprecaite your response
very informative info, is it possible to change pipe size to get equal BTUS,example if u have larger BTU airhandler then the condensor , does increasing pipe size or decreasing pipe daimeter give u equal BTU to get proper cooling operation ?
@@TaddyDigest I was at a job a while ago, that the airhandler was larger in BTU then the condensor, so they had to change suction pipe diameter to get same BTUS, it looked under engineered but did work.
I'm installing a Gree 4 zone 9,9,12,18 mini split which has 2 branch boxes. The longest run is 40 feet. I'm concerned if I run 2 handlers off of one branch box that I would need to increase the line size to the box. Is it a valid concern or would the system be fine given the short line lengths?
Hey bro, that was just excellent info that I was looking for. I just subscribed. Im building my own house and at drywall stage. But with all this heat, I decided to rough in lines and electrical for future if I decide to do air conditioning. Ive only got about 30 ft run from condenser to air handler but I need to do about 3 or four 90 s . The 3/8 line I may be able to bend gently and do the 3 or 4 90 deg turns. How do I run the bigger, probably 3/4? Can I solder? I've solderd plumbing pipes but I know I cant use that on these. Also are few bends allowed or not? Can you give me as much info as you can please? Much appreciated.
Hi there, I’m having a hard time determining if I need to size the lineset based on the condensing unit’s BTU’s or the Zone’s BTU’s. I have a Bosch 27k 3 zone mini split. Each zone is 9000btu respectively. Logic is telling me that I will only need a lineset big enough to cover 9000btu on each head. If I had a single zoned 27k btu head then obviously I would need a larger lineset. Am I incorrect? Thanks
I bought a 3 ton condensing unit to replace old 3 ton unit. when I looked at the vaporside port for new one, it came with 7/8. So, the pipe in the house which is 3/4 wouldn't fit. Maybe I need an adapter.

Great video. Thank you for sharing

Easier than I expected. Gracias
Great to hear!
Very informative thanks Tad!

Yes, absolutely. Always read the manual. That's the best advice.Thank you my friend
I'm going into pipefitting next month, this video is very helpful thank you!
Thank you man
Thanks taddy for everything .great content keep it up
your welcome 🙏 🤗 glad you watched
Just passed my epa test guys. Universal
Awesome congrats my friend Now you're more successful than you've ever been
Keep on keeping on
@@TaddyDigest thanks brother.
What would be the result if I used 3 /8 to pipe 3 hours power
Good information
Thank You Jack I Appreciate you taking the time to watch 😀
Do you only use ACR fittings? Can you use K or L type fittings instead? Sweat copper fittings.
Gracias por compartir tus conocimientos y experiencias. Saludos cordiales desde Guadalajara México
You're welcome my friend thank you for watching
What is the type of copper pipe is the coil pipe that you use for A/C?
Thanks a bunch Taddy! This was a grateful information man. Can you make a video about Piston Sizes Please?
Yes I can
But his humorous answer is that he wont
Thank you but you've been very helpful
This Video es perfect Boss

I would use a 90ﾟ elbow a 45ﾟ or a coupling.
@@TaddyDigest thanks does the 45 degree elbow sold in home depot works. Or hvac copper pipe and elbow are different type
Type K copper will work also?
Where can I find these catalogs and can I download them online?

I'm not sure if that's possible that's a good question though

It is common in the field to find pipe sizes that are too small for the newer equipment
Thanks!

Doesn't seem like a very long line set length
I would not be concerned
Is always consult the installation instructions for the equipment though
@@TaddyDigest thanks! I just realized the package comes with larger lines to the boxes so no need for me to worry about determining the line sizes.

you are correct
Can you crush outside copper AC lines by standing on them?
yes absolutely
@@TaddyDigest What symptoms would you expect to see?

are you sure it's a 3 ton 36k
@@TaddyDigest I am positive. Because I ordered 3 ton unit. Maybe I need to go double check. It looked definitly bigger than old 3 unit.
yea, definitely double-check
You can buy a copper bushing that will adapt to 3/4
I heard you was out of country Gov. stuff hopefully with good guys.

Im stuck on if i should install a 7/8 or 1 1/8 suction line on a 5 ton unit that has a line set run of about 70 ft which way would you go.
I would definitely install 1" and eighth
@TaddyDigest that's the way I was leaning thanks for your opinion appreciate it.
