After extensive research I'm a gonna say you need a duct about "this'' big.

The fact that air is exiting the drain line shows that there is a problem somewhere. The air on the positive press drain unit pushes the water out of the way from the drain pan drain line...

Take this in a good way. You remind me of my Mother, she HATED AC. LOL.

How about hard sheetmetal fittings using "canvas collars" for flexibility and sound deadening?

Has anyone used "expansion fittings" to take up that expanding PVC?

The list is long and distinguished. My 1st "coach" was a Guy named Jack Pelkey (from Canton, NY) and that was way back in 1969 onboard a US Submarine. Jack gave me my very 1st book, titled "MODERN...

It is my understanding that P traps are required on both negative & positive drain setups. And there is a fairly new trap design on the market by the Des Champs Co which has a "floating ball" in it...

Something ain't right. A comp cycling off/on/off/on,etc, by the "overload safety switch" is not a comp killer, does not kill a comp..

Does that mean every service call or every bid?

You started the College? Then finish College! I'm a Boss and I have had a dozen or so people that did the college thing, with my Blessings.

Howz bout killing that several thousand compressor by running it w/o an indoor blower? Bang, go ahead and be a comp killer.

2 reds,2 whites,& 2 yellows? Which is which? I don't know which is which, either!

Just a Q. Is there a reason you tagged on to a 9 year old thread instead of you starting your own new thread? Just curious , thats all! Tks.

OK & Tks.

Just because the refrig unit is running at temp(38*F) now does not guaranty the unit will be running in a year from now. What is SH at the comp(6" before comp)? What is the Compression Ratio? What is...

lol, who me?

Flapping Jaws. A 100" evap coil has a TXV set for 12*SH or another way of saying this is, "at inch # 88 the last drop of liquid boils off, leaving the last 12 inch of the evap for the development of...

A couple of things,
which way is North? and can you put in the rough location of the supplies and the 1 return? And did you measure room & the supply and return duct air temps?

Another time, this time right in front of my face. At a busy deli I was working on a 2 door RIF and I was using a 7' step ladder to get to the Cond Unit. I go out to my truck to get rags, water spray...

Many,many Blue Moons ago. My Tin Knocking Buddy & I were working on a 1 story bldg. My extension ladder was set up so we had access to the roof for the AC cond unit. The ladder was set up right next...

Isn't that head press a little too high for 134a? 125*F SCT is only 185psi

Gottcha.

W/ an infrared tool measure the couch, table, and stay away from the registers, far away.

Flapping jaws here, I think(ceiling registers) 3 ways near the windows, for interior walls/rooms.

How...

With the AC running. Measure the room temp in a few rooms but not the stairs/living room area. Then measure the air temp going into the return grill, right at the grill
How close to the windows are...

And thats why I luv u Bro......

Where are the returns?
Do not shop based on price.
It depends on.....

I make my glycol good for 10-15*

If ice was on evap coill then the glycol level is wrong

I would be worried if the drip was on the top of the joint

Adjust the CPR to control the comp amps to its max allowable setting, even if the press is running at 50psi.

I think that Copeland would love to get their mitts on and all over these in-warranty comps and see for themselves. Definitely request a written warranty report from Copeland. But until then, do that...

Why did the old system die after just 12 years?

I'm not talking 38-40*F box temps. I am referring to 33-35*F box w/ a lot of running time so there is a frost buildup.

To clean, To not clean. Soldering everything get cleaned, even the SB#8 solder as it comes off the roll, gets cleaned.

The brazing and not cleaning (as per some guys) of the copper/fittings is one...

I usually do 12 a day for 15 minutes (Grasslin)for extra cold units or 12/14 min defrost for Paragon Clock. The defrost time falls into the other part (6 hrs) of off time for an "18 hrs refrigeration...

Where did you measure the 7*F SH at?

What were those press? What was indoor/outdoor air temps?

Just happened to have a run cap?

The returns might have to be in parallel w/ each other, & not in series.

Our local "Two Morrows" Hamburgers had one up until 2016 or so. I started working on it in 1980.

Before/after the P trap? Sure it makes a diff. But show me this, what is the suction line temp just before the trap, the trap and the suction riser just after the trap? I have not noticed a temp...

Scroll comps running backwards make a funny growling sound.

Congrats!!!

I remember when I was new to this Trade back in 72' and I was introduced to condenser fan blades w/ slinger rings on them.

Is there a "P" trap in the plastic drain line just after the PVC exits the AC unit?

What is on the other side of those walls?
