I’ll tell you what it’s been like in the U.S. for me. I’ve been at it for over 20 years and have had my own industrial/commercial refrigeration business for the last 7 years. I did residential for a...

Because coolers originally with r-12 in it run forever with r-12. I routinely run in to small coolers with r12 that have never been opened for service. A jug of 12 can go pretty far fixing system...

and a parrot.

That's the right attitude. There are guys who get repeated call backs because they just don't get it or really don't care. Those kind of guys need to be dealt with not only from a owners perspective...

This comes with the territory of owning a HVAC/R business. No ones perfect call backs happen. A workman never seeing the kind of profits a business owner does cant afford to eat time so the owner...

I once ordered an impact wrench from sears online and it was to come with a free socket set. I called because they forgot the sockets and they said theyd send me them. They sent another $150...

I stopped using mine when I found out about the tiff zx. As sensitive as you need and no having to carry a box in one hand and a 4 inch probe in the other. Plus the annoying beep. Make a h10 in a...

I had the same problem in a drive in freezer the size of a football field. By the time I got it to the lift and in position it was hard as a rock and cracked in my hands. Pure hell

Hello,
I have a new trane comfortlink II thermostat for sale. $435.00 shipped. Message me if interested.

I agree. I don't know why we replace so many turbasheds. My only thought was the impingment screen on the outside wall of the helical separator may get partially plugged over time. I don't know why...

Nothing wrong with either setup. They both work fine. Just saying there's nothing wrong with switching oil systems.

I've never seen one fail but I've seen many changed out. So there's no impingement screen inside a helical oil separator?

Kind of on the same lines as jp you gotta make sure all floats are not over full. Sometimes you run in to a situation with ems and a oversized rack/small load where one comp will never run and it...

Whats wrong with removing a bad turbashed and installing separator and reservoir low pressure oil feed system? I do the same setup as jp to test if separator is working. I also will valve one off for...

What force in a ice machine do you think would cause a magnet to lose it's magnetism?

So safeway has known leaks and doesn't want to pay to have them fixed? I've never worked at a safeway but the 200 markets we service always want all leaks fixed right away without question....

Being low on charge can cause an oil trip.

Is the cost of modifying this going to be more than a new under counter cooler? You'll have to remove the old evap, install txv and custom fit the new evap, modify the refrigerant piping and...

Ridiculous and uncalled for. Just saying its not that easy to adjust setpoint at walmart. Sorry.

[QUOTE=Phase Loss;16417911]You can use the "super user" code.

Or call Wall-Mart monitoring & have them lower the temperature setpoint of the circuit.

It's just for a short period during the...

You have special access codes?

You can do that at walmart?

I was going to ask you the same thing. I was surprised to hear the high suction with the evap fans off. Maybe someone didn't understand the wiring or changed it so it could be a cooler.

lol yep been there

I've had the exact same experience with there equipment and customer service. They once told me the serial number I gave them for a new blast chiller we installed was incorrect. I sat there looking...

Use a lift to get it out. I guess you could deice it, replace the drain pan and heaters, repair the drain line, repair the bent fan blades and possible some motors, replace whatever caused it to ice...

Probably called on a Friday at 4:00 like it just happened. I wouldn't deice that. I would replace the evap.

Had one a few years back that was clogged like that. Had to replace compressor, cap tube and drier. Started back up and it was still restricted. Outlet of the condenser was plugged with the same kind...

Thats what I do. I gernerally dont make flares. On pressure controls, ultracap and things I make them tight and if they leak I tighten until they stop leaking. What else are you going to do. I've...

If you keep the crows foot at a 90 degree angle to the torque wrench you dont have to adjust the torque setting. It's only if you have it parallel you have to adjust torque because obviously it...

You did the right thing. Only takes a few more minutes to cut it out and replace it. I've been on a few calls working on roofs in -20 temps and 40mph winds where someone brazed over the rub through...

You set superheat at the evap. If the lineset is short maintaining compressor superheat at 20* minimum is more important than evap superheat. I doubt that ambient would affect 2 ft of suction line...

Whats wrong with adjusting superheat to 25 degrees at the compressor? If you have a short suction line you still need a minimum of 20 degrees superheat at compressor. Do the performance curve for the...

We got the plumber and stemfitters union. No refrigeration at all. I didn't go through any of it.

Just out of curiosity are you guys in a union that actually teaches and tests you on refrigeration knowledge?

They think that the HR coil was sized for a parallel set up and ended up being piped series? Would you have to pump out the condenser in a parallel setup when it switches to the heat reclaim?

With heat reclaim on and a full condenser you may get to a point where the hold back valve is coming in to play. Holding back and then opening causing the variation in receiver level. The 25 lb...

Dont leave until you find the leak. You know its leaking somewhere. Pressure controls, txv distributors, medium temp evap coils, flare nuts, liquid line solenoid valves, condenser coils....

Probably not. They're all the same. I once got accused of finding a leak and not fixing it. I tried to explain to them I have to find the leak before fixing it. They needed a new evap. They insisted...

As long as it shows in the glass I wouldn't worry about it. Even small k body compressors these days have an oil pump.

:yes:

If you service these it would be wise to carry a temp sensor and a pressure transducer.

Thanks for the tip about the towel. I service things as far as 6 hours away in a 2006 Ford with 200k on it. My lower back is just about shot from it. We run service vans to about 300k. They look like...

Hussmann smg service case coils leak a lot. We replace them all the time. Also don't be alarmed if your leak detector goes off in a hot water heat reclaim tank. The insulation will make it go off. Do...

We do more grocery store work than anyone and what jp said is spot on. For us by the time you make it to the machine room, and set down your tools, the office is on the phone asking when you're going...

Sight glass should be installed downstream of the filter drier. You can figure out if you're short on gas or the drier is plugged it's not that difficult. Best place for the glass would be at the...

My first thought wouldn't be to add oil. I would check to make sure someone didn't create an oil trap somewhere in the systems and that the pipe pitch is right. Check to make sure the compressors are...

This is correct. We had a problem with solenoid valves bleeding though so we called sporlan and this is the answer we received.

Found it.
