r/refrigeration

I work in office at this company’s Tampa branch and we are seeking experienced techs to hire. Check out the careers on the website for info, but if you’re looking for an immediate interview, message me and I’ll get you set up. We hire entry level as well and like to train guys, we’re just giving priority to those with experience. We actually cover all of central Florida from coast to coast, you can be based anywhere around here if anyone is interested.

I was told that when I replace a TXV always use the sporlan TXV with the pick up screen and where you could put a cartridge inside now my question is how do I determine what is the right cartridge when I’m replacing a TXV for a case because I know it has to do with the tonnage but how do I figure that out thank you in advance. This is an apprentice asking.

I have a r22 medium temp rtu for produce prep area and the high pressure control for CFB where cut in and cut out was set to 225 and 35 psi differential. So the cfm would look like it’s short cycling almost and cutting in and out often. Obviously w different refrigerants different pressures. I lowered the cut in to 175 to have cfm running longer w the same 35psi difference. Is that okay? Or what should the cut in and cut out be set to?

Hey guys, curious on what the industry leaders are where you’re from? Im from QLD Australia. Apac seems to be the most sought after units. What about you?

Whats the report on drive time? Are we getting payed to drive to the first job going home? If not what's the pay your accept for not getting payed

Hello everyone, rookie question: I have a WIF after leak repair and recharge getting about 15f evaporator superheat. Thinking that this isnt so bad because there is no pressure tap on this evaporator so my sst reading is taken from the suction service valve up on the roof. Which would in my mind be a few degrees lower due to pressure drop from the evaporator coil and lineset.

Not sure if there is some sort of calculation I can be using for accurate SST with no tap at the evaporator.

Rack refrigeration. I’ve been closing liquid line, letting circuit get down to suction pressure. Then I close my suction and pump it out to another suction line with my recovery machine. Is this the standard? All the guys I work with do it like this.

I’ve heard from other guys they just use the compressors. Because the rack is a giant recovery machine.

What’s your process?

Saw this post: https://www.reddit.com/r/refrigeration/s/8hnDYhwpKb

And I'm wondering if there is a mode programmed into most rack controllers that will pump down the suction? Or do you have to force the compressor to run past the low side pressure safety?

Walk in freezer at my parents restaurant went flat tonight. We’re in a very remote area and I need to get it going. Copeland tech support not answering so I’m coming here. I have a tank of r448a and am wondering if it could be used as a drop in for 404a? I mainly do resi so I’m out of my depth but any advice is appreciated.

Been thinking about this more lately while looking at how different teams handle their day-to-day work on the commercial side.

The actual refrigeration work is one thing, but everything around it seems to take just as much effort calls coming in, follow-ups, tracking jobs across multiple sites, keeping customers updated, chasing parts, all of that.

Once things start stacking up, it’s easy for something small to slip through and turn into a bigger issue later.

I’m curious how you guys are handling that side of things in real-world situations. Are you mostly relying on calls, texts, and memory, or do you have some kind of system you stick to when jobs start piling up?

Not talking about residential or HVAC setups strictly commercial/industrial where you’re juggling multiple jobs at once.

Would be interesting to hear what’s actually working for people out in the field.
