If you pump it down you don’t have to be in a hurry to tighten the suction it’ll hold back for a little bit don’t keep the compressor running pulling it into a vacuum. Christ almighty they’re letting anybody do residential these days
That made me cringe. Who even carries a pipe wrench in their bag? I can get most unions with my channel locks and service ports I use my pliers wrench and if you’re not boogie or in a walk-in use an adjustable 😂
I think the only thing he did right in this is use the service wrench. I always close both the suction and the liquid and slightly open the suction by a few turns so I don't have that far to go.
Use a gauge or two man takes 30 extra seconds. It’s nice to watch head pressure to make sure your not going to blow a coil in case it was overcharged, and suction pressure to see if you pumped down all the way
Well you almost got it right too long on the low side you don't want that sound watch the gauges once you hit around 25 psi lock it down that sound is damaging the compressor
Why would you pump a unit down without attaching gauges. Why press the contact with your key why not just use your finger😂 I can easily picture you shorting the key out and then Having to walk home😂
No it’s not unnecessary. You do that to see what is actually happening and then you can bleed off the remaining charge from there. Are you just gonna cut the pipe with a sawzaw before you empty it completely?
I like to start the unit, close the liquid valve, and pull the disconnect when it's ready. The suction valves in the compressor will keep refrigerant trapped in (assuming they're still good). Close the suction valve and do your thing. I'm not triggered by you using keys or not using gauges - what you do to a unit is your problem. 😂
Quick question i tried doing a oump down the other day on a goodman so i could clear my piston because it was starving my evaporator. Hooked up my guages and closed liquid line. Ran it but it only dropped 20 psi on the low side and jumped up 20 psi on the high side. There was still 65 psi on the suction side and wouldnt pump any lower. I let it run for 10 minutes and it didnt sound any different or change pressures. My question is, if i closed my suction, that 65 psi of refrigerant, would it have been in that suction line to the piston orifice and leaked everywhere if i took it out or was it saying that theres 65 psi and in reality there isnt any refrigerant on the low side?
What bro he can tell by the noise 🤦🏼♂️. I never had a problem doing it like this never. I actually use a paint brush from the pookie 😂 to hit the contactor.
all the haters in the comments lol. calm down yawl its just a goodman its not a carrier evolution or some kinda fancy trane. its a goodman, it was shit from day one.
Doesnt nobody else know theres a check valve in the compressor.... i never worry about closing the suction valve that fast. I dont even let the thing keep running. Once it sounds like a ford i shut it off and close the suction valve. Never leaks back out unless the compressor is fucked
Dude you can’t be seriously putting this out as your content, especially as instruction. One use the right damn wrench to remove valve caps, (2) gauges man, come on (3) yes you close down the liquid side and close the suction side to half then when below 20 psi close suction port.
You have to be careful doing that. If you have a long line set and not all the refrigerant can fit in the condenser, you can blow up your outdoor coil.
Bro you're doing 100% wrong. Get your gauges out and KNOW when the gas is 100% pumped down!! You will not be able to know from some sound the compressor makes. I've seen them unable to take all the gas also.
As a DIY guy with the vast experience that comes from having replaced a couple compressors on a sub zero fridge, I can confirm that this guys is talking utter rubbish.
I’ve ran across your page numerous times now and I’ve resisted from commenting before but damn man. Maybe you should learn how to do HVAC properly before uploading videos.
