High tubing prices...

if prices go up....just use smaller copper line right?

This is the splice in the ceiling to the existing copper...

There's 5 units at this office building....all different brands...And all state of the art installs like you see here....:D
I hear the roof units are in sorry shape....I'm afraid to look..

Sweet Jesus, that's incredible. Just flip that condenser upside down and walk away..By the way how did you get your pic's so small? I posted some of mine and they're way too big for the screen

Sad brazzing skills

Those old Ruuds wanted the 1/4" liquid line, that newer Heil probably doesn't appreciate it.

Size your pix in your imaging program before uploading. I use 640x480 or whatever the aspect ratio is.

looks like someone needs to the the fundamentals of brazing 101. That is some horrific welds. I was going to say I can't belive that they are not leaking, but I guess its hard to leak when you use a stick of silflow to braze each connection.

Yeah the RUUD has a 1/4" line...as does the heil...as does the 2 new DuKanes...He just spliced em in the ceiling to the existing 3/8" line (as ya see in that one pic..)

There's a lot of work in this building including the rooftop units.....there will definitely be more pics to follow...:D

Just braze the bejabbers out of that line!! It also looks like they crimped/pinched down at the dryer.

Isn't it a beautiful world??

These pics remind me of the pics I see on daily basis around the apt complex I work at. Theres a total of 280 plus units here and many have been done the same way on somewhat newer change outs/replacements units and even some of the coils. Most of the ones here are due to the fact that when the complex was built 17 years ago 1 1/2 & 2 ton Tranes were installed and 1/4" and 1/2 " were standard line sizes back then. The lines run in walls and between floor joists between floors( multi level apts ) so replacing line sets isn't a option. Now anytime I have to replace a condensor or coil at least I'm using reducers to keep from doing the crimping thing...
Now a ??? for those more experienced then me. Is there any formula or rule of thumb I should use when checking pressures ( especially high side ) to take in consideration the down sized line sizes. What I'm asking is do I need to run a lower or higher pressures based on the smaller line sizes.
Thanks,
Martin

now thats some quality work for u.. what size is that suction and high side line?? what size is the condenser/heatpump?
