This is a VAV system? Acceptable airflow is a very common issue with VAV DX, VAV works much better with chilled water.

I believe your refrigeration is oversized at this load condition. You need...

This is also gaining traction

This is a wise statement that is getting truer all the time

LOL

I've had my share of those too

Personally I like the nutty character of oil15

I got in the habit of bringing empty and evacuated 125lb cyl's to the job and letting liquid run into them, usually there wasn't much vapor left to recover or you could just change a sensor with less...

I have transferred plenty of times, and it has worked and not worked,but trial and error has inspired other methods that work better for me

Recover into a cylinder, or pump and transfer, you still...

Right

Same thing

You still need a portable condensing unit

But I would be surprised if the evap circuit had enough room

I gotta ask

How do you replace the saturated condenser temp sensor without recovering the refrigerant?

Or at least recovering down to a reasonable level

Is the defrost timer adjustable?

What type of product are they keeping, and how often does the door(s) open, in what environment does the box live (humidity) , and is there a door switch for the...

Wait a minute guys, if you look at Red Wings web site, at the pull on Pecos in particular, you will see 99% of that particular line is USA and goes for around $200. Personally I think the hand made...

Just wondering Turbo, if you are only using your MB, and the larger ones are in the garage, what are you carrying (the rest of) your service tools in at the moment?

I do agree with you about the...

There are many different levels of quality, price, experience and company of the tradesman, etc...

Perhaps the customer got a good value on this one considering what they paid.

If someone is...

Since you only have 2 stages of cooling, why not change it up from the norm and bring on the refrigeration based on OAT? This will also help minimize cycling.

You know guys, this is a post from
someone who has a great attitude. That's how an American tradesman should see it.

Must have been a mis-manufactured compressor.

A plugged drier would not have spiked the current draw in a system with a proper charge. Especially not in a system with a low charge. It would have...

Thank ya for the update

I experienced the same

Maybe the cylinder was a lil tighter than expected...

There may still be an electrical problem, but does sound like a restriction upstream of the liquid line, those will raise the current consumption in a heartbeat.

This reminds me I had one of...

It may be time for a piercing valve on the discharge line before anything else. Only takes a minute.

Is this a capacitor start and run compressor with a potential relay? Seems like I remember...

No prob good luck!

Okay well that clears up a bit.

The next question would be head pressure control. 50F is not too friendly for a standard RTU.

You had some load inside, adding some load outside by covering...

If the OP has an 80F return, chances are he has an 80 plus ambient, and he should be running a higher discharge pressure even with reduced evaporator airflow. Assuming the capacity of the new tandem...

Sounds like you did a good job. No mention of ambient. Discharge is low, add more refrigerant and see what happens.

Very impressive performer

Interesting. Serious water pressure. Is there a reason to close both lines and leave the coil with no room for expansion?

Seen it done both ways - close the leaving - close the entering.

In...

I would say one with a level of sophistication.

A small bit of information-

Variable air volume is a different system altogether than a constant volume zone control.

VAV is used on large central equipment with capacity control.

As I send from my iPhone.

Shakes head.

Shame on me.

I need to run up to the store now.

For some liquid refreshment (dinner)

haha
I get a feeling you are with me on this

generally I frown on modern society

Personally myself, do not care for these emerging nu skool resi and retail service organizations, who are concerned with regional dominance and never ending growth, more so than actually doing real...

So the purge discharges into the cylinder instead of the atmosphere?

Hello Rob, could you or someone else identify that "propane tank" on the side of the condenser for those of us not intimately familiar with low pressure refrigeration?

It appears to be a factory...

I'm my experience, it has been the opposite. The mom n pop shops are doing better work than the big guys with many workers. (exception being large mechanical contractors who have a standard of...

Tech Rob mentioned Snap-On and the like.

I have few of their pieces that were handed down.. Very nice and functional. I can't afford them. More for auto mechanics that use those types of tools...

Cheap and fast..

We were just talking about that today. Contractors doing installations for peanuts, spending little time on the job and exhibiting no workmanship, making the other contractors who...

That is a good question. My thoughts are, if you were speaking practically, in real world operation, the exact bulb location does not make too much of a difference. Provided it is securely fastened...

I'm with Turbo. Sears is still a GREAT place to get good quality, American made tools, at reasonable prices, with lifetime warranties. I just purchased 2 LED inspection mirrors and a small level that...

The proper green or gray would be nice.

At least they didn't paint it tan..

I would like to see it fixed vs a likely scroll replacement unit. ..cheapo

Those were good units when...

Good luck on the repair if you have not already completed.

Hahaha okay. You got me on that one!

Is this the factory paint job?

Sure, and why not?

Anyone feel like lunch?

How does one achieve this level of artisan like display?

Thought it was time to set the record straight and show the right way to add a new condensing section to an oldie but goodie package unit.

Enjoy!

That is nice Dallas, if you had a lot of rooftop recovery, it would be a good choice.

Mine was salvaged with no expense though :)

I have a coaxial rig also. A ton and a half. Don't need much water flow either. Major subcooling and recovery speed increase. Goes between recovery outlet and cylinder inlet.

The digital scroll is actually a cool
device. It allows a greater range of capacity control than traditional unloaders on a recip.

It is designed to load / unload frequently to deliver a...
