    Sorry if I missed it if you did mention this, I think it's critical to make sure people know that after a burnout assume you have acid always and do a test on the oil in the crank case, test-all is a great kit to stock on your truck. You can test poe or mineral oil w that kit. If your test fails, best practices are to use r11 flush or similar and then add a suction line filter drier made for cleanup but do not leave on the system, I think you did mention not to leave on system but it's important to remove that drier after a couple days and re test with the quick tests you showed while the system is running. Read directions on your test kit. It makes a difference. If you still have acid you need to install another suction and liquid line drier all over again, and do this however many times that's needed till you can pass a test. I will even reflush with the r11 and in extreme cases even add a scavenger and that works really well, then remove suction drier permanently and install fresh liquid drier and you're done. Install flare driers and add ball valves even to make life easier. Many times it will take multiple rounds to be acid free. It's just what it is but if you leave any acid, you'll be back,or a different company

    @rcinfla9017 Год назад +1

    Kalos gives good training for their staff. More shops should do this. Great you invite us in.
    Have you ever seen a replacement compressor have hard start issues due to excessive oil from original compressor throughout system adding to a full fresh load of oil from new compressor? Refrigerant charge level and voltage drop to contactor during startup surge current are fine. (8 degs subcooling, 230vac during 109 amp startup surge current). Original scroll compressor failed for compression, so no motor burnout contamination of oil. Run cap, contactor, and liquid line filter replaced with new compressor.
    The longer the system is off, the more sluggish the compressor startup, which makes me think it is oil draining back from five foot higher evaporator with 20 ft line length between. The time factor could also be caused by de-wicking of oil from motor stator windings back to oil sump of compressor.
    Believe this is a case where compressor failed for poor compression, but enough compression to get some liquid (at cooler nighttime), with oil, to evaporator but not enough return line vapor mass flow to return oil from evaporator to compressor. When new compressor installed with full new oil load it drove the oil stuck in evaporator back to new compressor overcharging it with oil.
    As you mentioned, understand the failure mode of previous compressor to predict possible consequences for new compressor.
    Copeland official stance is only way to be sure of correct oil load is to pull compressor out and drain oil out suction port, assuming it should recover about 87 to 90% of full oil load specification, allowing for recovered oil loss of 8-10% system distribution and 2-3% motor stator windings wicking absorption of oil.

    Those quick check acid tests are not the most reliable. I understand that that in residential you don't have and oil port on your compressors, so it makes it hard to test the oil directly.....but if you are replacing a compressor......i would definitely recommend using the Phase 3 acid test kit.
    I will weigh the oil removed from the comp and check it vs the data tag...you want to get all that oil out of the system....scrolls...if not under warranty....i always cut them open to find out why it failed...if you dont know why....you will be back to replace another one shortly. They do make HH bi-flow suction line driers. I've used them before and had no issues at all. We also use acid scavenger as well as a suction drier. Use lits and lots of nitrogen and purge the contaminated oil from the system. Use the pipe wiper. If its a burnout on a HP....I always replace the RV as well.

    • @donjohnson5172
      @donjohnson5172 Год назад

      Why are you changing an RV as well? They don't exactly carry a lot of oil, and so the acid isn't going to pool up in them very much.
      Changing an RV is a lot of additional labor that a customer may not need to be paying for.

    Agreed...todays HVAC systems are not built as well as the older stuff thats 20+ years old. So, it's not the best idea to suggest a bundled system replacement when a compressor or evaporator part will restore an older rig. Most of those older R22 systems were built for the long haul unlike todays cheap 10 year life span units. Aluminum vs. copper, chineseium contactors and capacitors vs. USA, control boards galore...in the air handler, the condenser and other components all ready to fail due to cheap manufacturing processes. I have seen a few new condenser control boards that act as the contactor...high voltage wires connecting directly to them ! There is a design that will fail everytime too soon and not $30 to fix but $500 if you are lucky to source the part.

    • @HVACRTECH-83
      @HVACRTECH-83 Год назад +1

      @Garth Clark I disagree with some of that. The biggest cause of short lifespan on modern equipment is usually poor installation practices whether it be from the installer not knowing the correct procedures or careless techniques which introduce contamination/non condensibles. That's the biggest cause rite there, moisture and contamination from brazing without nitrogen. I see it too often. Then you have alot of homeowners who can do any job themselves, enough said there. Now I do agree that pcb's can be a weak link in systems and the older systems didn't have any boards , tech has really come a long way since the 80s but because of that so has efficiency so the new tech is much welcome. There's also brands still making superb quality units today and if installed and maintained properly will and do still last well over 20 years and as time goes on who knows maybe we will see systems over 30 or 40 years old in the future still. That is as long as these manufactures don't keep playing the obcelence game like apple and the others. From what I see, that is a major contributing factor to a system that otherwise could last another 20 years or more needing to be replaced. Dealing with that rite now at a middle school that needs a 1.5 million$ lead lag chiller swap. Can't get the controls anymore and nothing available from anyone that could be compatible. Very unfortunate. But not all manufacturers are like that

Same goes with plumbing fixtures...many homes were built with the sewer pipes designed to work with a minimum water volume and cannot function with the low water volumes newer plumbing fixtures have. Had an issue with that once and found out the sewer pipes won't push out the waste with only 1 gallon. Kitchen faucets are next to have parts for...the Government thinks that 1.8 gals per minute for kitchen faucets is helping when in fact that idea is hurting most homes. Garbage disposals won't work as they should with a low flow nor will it save any water. Same with the usage of said faucet, forcing people to wait to fill their sink to wash vegetables or other needs is saving water? No...its not but it is a nuesance idea.

      @Garth Clark I still strongly disagree with the most hvac techs will agree that equipment is not built to last part. I believe that's what a tech would use as an excuse and I see it all the time. You can't prevent a pcb malfunction that was going to happen anyway, but just about every other part of any system can have a very long service life if given chance, that includes compressors,motors, contactors , motor starters, txvs especially, reversing valves as well, these are all parts that should and do last 30 years or more. A compressor doesn't just die. Usually. Contractors and starters die from short cyling/overheating/over current. Txvs 95 out of 100 times is contamination or rub out, reversing valves same thing. Contamination. No other way they can fail unless the very rare time a cap tube joint breaks but that's pretty rare and would be linked to excess vibration. The point is, soo much failure can be avoided for our customers and our reputations by knowing what's not normal when we start a system up and watch it run, every install, every screw terminal needs to be checked for tightness, every spade connector, if it's loose,tighten it. It's easy. You never know when you'll be back out a month or two later for a blown fuse,tripped breaker,whatever and a burnt up connection or bad moter even .

    What about lightning? So we had a lightning storm come through yesterday on my way to work after the storm, girlfriend said unit started making "some noise" so she turned it off. I came home tried to start it up and no condenser felt it hot to the touch, hosed it down and let it cool over night, swapped out both fuses on the disconnect and tried it, still nothing. Then I noticed the wires connected directly to the condenser itself were sooted up so I get in there and notice one of the wires is melted so I cleaned everything up with wire brush and cut back all the wires and completely re wired it up with fresh wire. So now it turns on but cuts right back off. The lightning probably killed the condenser? Or did I burn up the new fuses because I tried to run it with the wires like that? I guess I can try new fuses otherwise it's toast right?

      Hi Joe yes, a standing pressure test does not involve nitrogen. We just took that part out of the video.

If your standing refrigerant temperature is below outdoor ambient temp that is a good indication you are low on refrigerant.
