Ok, I would guess that these pipes are holding close to about 600 gallons of water. All the air should be out of the system and it is just water. The building that they are in is a warehouse and...

If the job in san Antonio doesn't work out, feel free to contact me. I'm an hour and a half north of there but I would like to talk to you as well. Commercial Refrigeration. I taught all my guys in...

Hey guys, I am installing my first glycol chiller for a local brewery here and have a question about leak testing the closed loop. I'm using 4" pre insulated sched 80 pvc for the loop. I installed...

I usually don't even worry about a disconnect in a freezer. I just shut the condenser down to service it. Here's why. Electricians almost never fill their penetrations with silicone, let alone the...

How much money has KD lost on that machine already by paying out on warranty labor and parts?!?!

We are reps too. You guys been replacing many fan cyclers? seems like I've replaced a dozen in the last year.

if you want a 35 degree box temp you will need about a 20 degree coil temp. with 410 that would be around 78 psig. I have never seen 410 on a walk in cooler. the only time I have seen 410 on any...

Try Razorsync. I've used it for a couple of years and works great. Very customizable and has all the features your looking for.

Couldn't agree more with this guy. Why do it. It's incorrect. What happens when that compressor takes a dump in a year, then what, just put the same comp in? Do you know the history of that...

Don't do it. I have had the same experience with iim, fortunately I found out mid service call that they were shady. For all I know that true freezer is still torn apart with a bad element. And the...

Exactly what brewmaster said is what I would do, especially if someone was working on it before me.

Hey guys, hope all is well with everyone. Got a question for the Scotsman gurus out there.
Got to this machine, only 5 years old and was frozen solid. Let it thaw, then ran it again. Everything ran...

Obieone, I believe these units are around 3-5 yrs old. This restaurant is not very old. That makes sense what you're saying. Can you bypass those sensors? Or is the board looking for a specific...

Slctech, I sent you an email. Yes there is an economizer on this unit. It modulated during test mode.

I didn't see a board in the blower compartment. There was a smaller board at the top left with the big red LED light. And there was bigger board with several flashing LEDs to the right of the smaller...

Ya I want to say the board too but I want to be sure. I have the voyager bible somewhere but I can't seem to find it.

Hey guys, working on a trane RTU model:YHC072E4RLA
Unit won't kick on in cool. The blower comes on but Contactor for comp won't pull in. So far I have verified that no voltage is present at...

3 evaps?

Ambition,
Get into refrigeration and stay there. It's year round work and something different everyday. I am a small 2 man shop including me, and I am constantly looking for young guys like...

I can't stand it when I see those line sets coiled up like that, it looks like crap and can't be good for oil return.

I am going to be working on a lot of PMJ445ECSE fryers in the future. I have only worked on a few. Is there a good tech manual on these? Where can I get one? Thanks

Is the company that installed the unit not a certified Trane installer?

It's definitely a Scotsman. When the red refrigeration light comes on, that means your supposed to disconnect it and throw it in the trash.

Unplugged the evap fans and stick a digital temp probe in the coil to verify cut ins and cut outs as well as the consistency.

A good puller. I believe the " ultimate Puller" is the one I have.

Once that nickel comes off that evap it's time to get a new machine.

I went through this situation and lost big time. I got my state license and thought that my old boss would give me a raise, more responsibility, etc. it didn't happen. I had 145 hrs saved up because...

That's the way to go man. Go to school, and on your days off try and work with a small company who is wiling to work with your schedule. I just hired my first employee 8 months ago. He was a...

Bayhvactech, start another thread that is titled, " how long did it take to get out on your own" you will not find many, if any, guys on here that got into this trade and 4 yrs later were running a...

TXV power head failure?

Don't do it. It doesn't add up. Think about it for a minute. If this dude is so busy and a guy like you comes around with some mechanical background, and a passion to learn, he would hire you, train...

Yes. I have an iPad, I got an app called quick sale. I think it was $50. But I can generate invoices from the field with signature capture and email them to customers. It also has an inventory...

I'm in my 3rd yr on my own. Been at it for 13 yrs total. I do mostly commercial refrigeration work/ restaurant work. This last year I picked up a produce facility with 26 walk in coolers. There were...

It just flakes off and blows through the registers. We had our last cold snap here in Austin so in cooling it shouldn't happen because the coil will be wet.

American standard told me that it's aluminum crystalline oxidation and will only happen in hp mode for the first two heating seasons and then will eventually clear up. Or you can replace it with the...

I called today, they did say there was an issue and would replace with an epoxy coil, but will only pay 2 hrs labor to do it. That seems a little weak in my opinion. Thank god this is a friend of...

Last year I sold 8 new systems, all with tam7 air handlers. I have had no issues with any of them until today. I got a call from a customer that said when he turned the unit on it was "snowing"...

Call tech support and ask for it. They can email you the list.

There is nothing you can really do until you get the building to positive pressure.

Use the ranco A12 constant cut in controls. Also, true has a parts stock list that will fix 80% of the issues you would come across.

I would do it for sure. But I would only lease a brand new machine to someone. I would try to get my money back in 18 months. Then you have an additional 18 months where the machine is under...

Yes those dollar amounts are correct. And i agree, I'm not sure of any commercial building that I have worked on that is less than $600k in value, therefore I carry $2 mil worth of liability. And...

Welcome to Austin!! We need more techs here for sure

I get that, I hold a class A combo. I'm just saying for another 40 questions on a test you can work on anything, why not just do it.

I never understood why you wouldn't just take both tests in class a. You can work on anything for 40 more questions.

There are only two ways to do things in this business. The right way and the wrong way. What you're fixing to do would be the wrong way.

Ambient is pretty low. From my experience you should be around 130-150 psi and 14-18 psi when box is at 38 and ambient is between 80-95 degrees. If this unit is going to be in a hot restaurant...

Yes, I too prefer grasslins over paragon. I recently started doing work at a huge produce facility and changed out around 12 old paragons with grasslins and have probably returned 8 of them. Some...

Ok, so I have gathered some more intel. The pervious motor was a 975 rpm motor. He put a 1075 non OEM motor on there. Maybe because the blade pitch didn't change and now running faster with the 1075...

Weird issue here. My buddy called me and said that he had a condenser fan motor go out. He replaced the motor and cap, 2 hrs later the motor burned up again. Blade is on correctly, rotation is...
