I still dream of the day that I never have to service any type of reach in cooler or freezer after 30 yrs of doing such. I can say that these days, I never "pull" out charge and attempt to pull vacuum on such vs purge out to charge back in factory ounces of nameplate charge if such can be still read. Why would anyone pull a vacuum on a known leaking system even if the system may hold a vacuum/ leak gets sealed in vacuum and only leaks on + pressure. I know exactly what pressures I want to see with taking into consideration many things like box temp, ambient temp, compressor amp draw, condition of coils, what is inside of box and what temperatures/ etc. I've replaced hundreds of such evaporator coils that are same as in AC, 90% of time of leak source. I do not replace such coils anymore. Top off charge, see how long it lasts.. If has to be topped off again after a long time, like many months, 😮 then offer to put a sealant into system and hope for the best.. With splitting condenser coils to clean, depending on condition and age of unit, I also do not do. Nothing like doing heavy maintenence on an old neglected RTU or whatever and splitting coils causes them fragile U bends to crack open! Pressure wash with coil cleaner from both sides instead of risking destroying with attempting to split coils to properly clean! Decades of experience talking that misses greatly R 12, 502, 22 etc.
What is your practice on charging Azeotrope, two component refrigerants? Do you pull out the remaining charge or add to it? Just curious on how others deal with these scenarios.
Almost everything is a mix today. It depends how much refrigerant is in the system but usually I haven't had many problems with fractionated refrigerant.
Quick question if you have time. I have a walk in freezer and my Scrool compressor seems to only short cycle on really hot days. I have confirmed it’s cutting in and out at proper pressure and it’s not pulling into a vacuum. I’m a little stuck on this one as it won’t seem to happen until about 90 degree ambient temp. Thanks for your time
I need more information. What refrigerant is it, what is the cut in and cut out pressure, is it short cycling at the end of a cycle after it pumps down? Where is the solenoid valve? Is it inside the EVAP or at the condenser? How many feet is the condenser from the EVAP ?
Thank you for the response. I didn’t want to send a message with all the details in case you weren’t able to respond. The unit is 404A Cut in and out is at 5 and 22 roughly and is confirmed on gauge It is short cycling after pump down and then re engages a few times before fully satisfying. It only happens in hot weather (94 plus) Solenoid salve is on top of walk in and it’s accessed by and access door. The condenser is on the roof so the solenoid is roughly 3-5 feet below the condenser but not in the EVAP. Condenser is roughy above the evap about 7 or 8 feet if I had to guess. It’s a heatcraft unit with liquid injection / Scrool compressor
@@brushben22 the hot weather is causing refrigerant to expand and raise the cut in pressure switch. 22* is pretty common cut in my area for our weather because we've got to set them low enough that it will come on in the coldest of winter. What you could do is try lowering your cut-out pressure. See if I can get it to cut out at maybe one pound or two pounds. What's happening is the residual refrigerants causing the switch to kick back on.
Thank you and I’ll try adjusting. We are in California and we have very hot weather in our location for the most part. Winters never get to cool so I was thinking 1-2cut out and maybe 25 cut in. Thank you
Thanks again and if you ever get a free moment I think it would be very informative to explain cut in and cut out pressure and the variable factors that can effect your cut in and cut out pressures. I’m newer to refrigeration and I have a general rule of thumb idea about cut in and cut out but I could def use some fine tuning. Thanks again
Question......in the automotive world if you have an AC system leaking refrigerant your not technically allowed to legally add any refrigerant until the leak is fixed. Why isnt this the law in residential and commercial hvac?
Find the link to the epa law and post it here, I have both certifications. A lot of that is a store policy to scam people into spending money. The last time I checked the rule said anything over 50 lb had to be repaired. Whether or not they said it had to be repaired immediately is a different subject matter. All my jobs are being quoted with the option to repair and if they choose not to do it they're wasting their money. Cars use less than a pound and a half it's hardly even worth worrying about. They want you to spend $2,000 in parts n labor to save from spending 50-100 bucks in refrigerant
In general, owners or operators of an appliance that is leaking ozone-depleting refrigerant above the applicable trigger rate must either: Repair leaks within 30 days from the date the leak was discovered, (didn't grab the full quote) from the epa. I teach automotive hvac and I think the key word is ozone depleting now with that said in the automotive world the key word is detectable leak I will do my job and try to find it but I'm also not going to spend 4 hours tracking down a pinhole but with the refrigerant we are using 1234yf that stuff is incredibly expensive and our machine that we use does a leak decetion and if it finds one it will not let you gas it up and go
How do you get into racks? I'm a commercial AC guy for 7 years want to specialize. Thanks for splitting the coil and doing the right thing even though you just wanted to get out of there! You can sleep at night lol
The company I work for is one of the largest companies in the area. They were doing racks before I got here. We also do a lot of industrial and food processing plants. I can't show a lot of that due to restrictions.
If you do such long enough, then supermarket racks that hold hundreds or even 1000+ #s of refrigerant will find you along with 100/200+ ton chillers along with boilers rated in HP, not just BTUs that if coverted would be millions of BTUs. Do long enough and you'll get a taste of everything. Always try to learn new. Go to trade shows like AHR. Ask questions always. Seek out more U tube channels like this one. One of the best trades I can say HVACR is. 100% economy proof, recession/ inflation proof, demand/ supply proof, and even pandemic proof. If you get good, then no way possible shape or form that you'll ever have to worry about not having work that pays very very well. Along the lines of what most doctors and fewer lawyers make.. If you don't mind hard physical work and your mind always getting challenged with how to do and constantly having to learn new things on a daily basis.. Keep learning this trade. No one person can know all of it, nor even just a small fraction of it, even if change stopped today in multiple lifetimes
Depends on the part needed. We will quote it and get approval first. Where I live we cover a very large area of Ohio and everybody knows everybody and we do a lot of work for this franchisee owner, he owns at least three or four subways in multiple little towns. I was service manager at my previous job and I did quotes, warranties and all the other stuff the manager would do along with running my service calls after the first 2.5 hours of the day. I can do it, I just don't have to do it here.
95% of the HVAC workers are a joke. Leave and let the next guy take care of it, attitude. Why nobody will work with me. We stay until the customer is satisfied or you can leave and never come back.
Appreciate the fact that you split the coil to clean the middle, pointless to do the *outside* when the middle is clogged.
