install line damage


Basically your saying, among other things, that my insulation, there are leaks in the ducts and tape joints.

-can one use this metalized tape "grip mastic" or does one need cloth tape + mastic. The metal tape I have used is excellent and has held for years.

please clarify "the low side line" needs to be insulated all the way to the coil. What is the low side line...pressure/size??? Are you you saying that the 3/8" inch (liquid??) line from the compressor needs to be insulated??

..."liquid makes it back to the compressor"...I'm confused.

Thanks

Call them back to correct all that! The company doesn't close when the owner goes on vacation. See that little brass piece in the pan under the coil? Hopefully the stuck another one in because that's what meters the amount of refrigerant going through the coil.

yea was wondering about that....
The co. owner (OMG a friend of mine) said "hold on to that you might need it".

OMG he should have known immediately what it was and that his "expert/craftsman/professionalinstallers" screwed up and left it out...

this is why my unit is not working...!

It was -+ 115 degrees in my attic but there is no excuse for this....I have spent many hours myself up there in the "oven" working....fixing their "work".

Could be one in there. One comes in the coil and another comes with the condensing unit,supposed the use the one that came with the condensor. They can check when they pump the unit down to fix the kinked line.

Dang man that's what you paid good money for so stop fixing things yourself! If the guys need to spend another day in the heat and the boss doesn't make any money on the job the maybe the next customer will get a better quality install.

First of all let me second what Marty has said, the company should not be closed just because the boss is on vacation.

The black insulation on the low pressure vapor line (the 3/4" so the bigger of the two lines) at the upstairs unit should be all the way to the evaporator. That bigger line should not be visible anywhere, inside or outside and all inbetween.


Carlisle makes a mastic foil grip tape that is code legal. Once it is stuck on something, it stays put and takes some serious work to get it off. It looks like regular foil tape but is thick with a gummy sticky applicator on the underside. It is cleaner to apply than the actual mastic/hardcast which is why I use it and it again, it holds with no drying time like mastic has.

Looks like a full size suction line coming out the air handler. He would then have had to upsize it under that black insulation. I enlarged the pic many times and it looks like the original pipe coming out the air handler and thru that black grommet. The brass thingy (orifice) may be an unused extra. The coil in the airhandler is probably used for a 1.5 or 2 ton unit and the correct orifice inserted ( one that came with the condensor). Post the model # of the airhandler and condensor and I have access to some Goodman specs and Amana its sister.

If the temperature of the vapor refrigerant heats up enough (picks up enough heat to turn back into a liquid) than liquid can make it back to the compressor. OUTSIDE OF THE OILS, A COMPRESSOR SHOULD NEVER HAVE LIQUID REFRIGERANT IN IT. IT IS A VAPOR PUMP AND NOT A LIQUID PUMP. If that colder vapor refrigerant picks up enough heat it will have a great chance of turning back into liquid and sluggin that compressor, killing it.

And in the meantime while you are pumping liquid and essentially waiting on your compressor to die you loose system efficency resulting in not proper cold air.

It is why insulation is used on the low side, yours being 3/4" and should be everywhere on that line, no holes or visiblilty of that line anywhere in any way, shape or form.. That line should not show itself anywhere.

A lot of times that little piston which is sitting in your drain pan and should be in the high side line at the coil is an extra as one coil can fit a few different size systems, dependant upon the size of the hole of said piston and again, sometimes the coils come with two or three pistons and you only use one.

If there is not one in your line as in if that one should be in there and is not an extra than you are receiving liquid into the coil and so the refrigerant is not evaporating efficiently which could be why you are not getting cold air, less coil capacity, and your home is staying warmer than desirable. That coupled with the lack of insulation could spell disaster.

You guys have been great...
[BTW the reason I fix and redo stuff poorly done is 1: they will come back and the fix will make things worse/do more damage and 2: the the folks (professionals) performing the fix/work are just not made of sufficient brain power and/or just not wired to understand what quality work consists of!]

I will get some more pictures but here are the owners manuals that came with the units-

coil


condenser


heater


question...the wire in the package...should this have been installed/used somewhere?

+ where do I find the specs on the coil...I'm headed up to my attic now but I do not recall any data plates on the outside of the unit?

bailing wire wrap arounds will tighten up that insulation but make sure the actual duct is tight to the unit return(must you will suck in attic air) and or supply lose it in the attic.no trap on that condensate and where is the over plow pan line end up outside you need to view it up front of house or over kitchen window.that KINK was from something being dropped on it might of been in his truck rolled 5/8ths and the vac pump was thrown into the back and ba boom he installed it and figured "ah HE won't see it" now its a recovery..rebraz..coupling nightmare make sure they revac on a recharging.that pipe took a hit from above doubt it when installed channel locks on it no slip scars and then why would he...get them back to trap and find the end of that overflow pan to the outside

thanks biggles....what does this mean?
"recovery..rebraz..coupling nightmare make sure they revac on a recharging."

I'm am still working on the overflow pan line. I decided to move it so that it parallels the condensate drain line...simpler & cleaner.
