the dryer vent into the garage is super lol. I guess it would heat the garage in cool weather(re-lol). I could see doing that with an electric dryer in colder climates and a drafty garage (if not the humidity would be bad and mold everything/structure) watching more, I bet the dryer used to vent underground through the green SDR pipe and elbow sticking up behind the condenser! It surely clogged with lint/leaking water in and breaking clothes dryers(blowing thermal fuses and other), so someone's hack fix was dumping it into the garage!

That white van will stay nice and cool. Guard your refrigerant supply. A few days ago I heard on the police scanner that thieves broke into somewhere and stole refrigerant! You would think they would have just run that copper line into the wall, instead of putting it under the slab. That is how mine was done. It goes into the brick, into the attic, and comes down into the hall closet evaporator coil and heat strip resistance money burner heater.

For the leak of the service on I don't know if you noticed it when you went to Valve it off for a pump down you could see a little poof of liquid freon spray out more than I could just a bad seal once you open the valve it should seal it and the same goes with the cap unless you price it in to replace it and the freon which is a lot more as you know

Glad to see you are getting the van back, will be nice and easier to work out of. Do you think once up on a time they had a smaller unit that used a smaller line or was it just incorrect from the start? Reason I ask is my unit is old, so when I do the change out, I may need to run a new line set. It won't be easy on mine. I guess check and see what the new unit calls for and go from there. I just answered my own question. Nice job Curtis.

I have soldered electronic components in the past and if you did not want to over heat them you would use an alligator clip as a heat sink. You could have put the valve cap back on or get a large fitting with the same threads as the cap and put that on the valve to draw the heat away. Heat travels just like electricity and the bigger the wire the more current/heat it will carry away. I don't know if that would make a big difference with a torch in such a small distance but it couldn't hurt.

I worked in electronics repair years ago. Now own a hvac company. I use my soldering skills to repair many control boards that develop cracked solder joints. Its very common on certain brands molex plugs. A soldering iron gets to around 700 degrees max. Oxyacetylene brazing can get between 6000 and 7000 degrees.
@qyouwilber5734
@qyouwilber5734 Год назад
@@cal3178 copper melts at 1900 degrees. If you are brazing at 6000 degrees it probably won't work. I looked up brazing temps and they say 850 to 1400 degrees. You can also solder the connections like a plumber would if the code allows. He might be able to use a large spring clamp with the rubber removed to help draw the heat from the valve.

Just a note when ever you are pumping down a system always install gauges so you know what pressures you have. And never pump any kind of a compressor into a vacuum. With out gauges you never know if its in a positive or in a vacuum. Im sure that I'm wrong. Just do it the right way.

@jrtakesthesky27
@jrtakesthesky27 Год назад
Close your high side service valve by front seating it and keep your low side open. Run the system in cooling (aka just press the contactor down). You usually want to monitor the low side pressure but in this video's case the condenser is frozen so there is low to no risk of over heating the compressor windings. You wait for the Low side to get just under 0 psig, you want to lose as little refrigerant as possible. Remember the compressor needs refrigerant to cool it down so don't run it forever in this vacuumed state. Then you can close the low side service valve and you now have a condenser pump down.

Common liquid line restrictions include clogged filter-driers or metering device restrictions. Many techs think that refrigerant will exit the compressor and back up against the source of the restriction, which would raise the head pressure. However, that’s not true. Our diagnostic sheet shows that liquid line restrictions cause low suction pressure and normal to low head pressure, not high head pressure. That’s because the compressor requires refrigerant of a specific density to pump refrigerant into the high side of the system; when the suction pressure is low, the compressor can’t move as much pressurized refrigerant to the high side, so a liquid line restriction doesn’t have a huge impact on the head pressure when you have reduced amounts of high-pressure refrigerant in the liquid line in the first place. Some thought experiments that can help you grapple with that idea include thinking about refrigerant in a tank and the pump down cycle (used to prevent refrigerant migration). Note: don’t pump down a microchannel condenser! However, when you have a restriction, its location has a significant effect on the head pressure. The amount of charge also matters, as overcharged systems are more likely to have a significant impact on the head pressure (raising it and causing hydrostatic pressure buildup within the system). The most common liquid line restrictions are clogged filter-driers, metering device inlet screens, a kinked liquid line, or a TXV with an empty bulb. These very rarely cause high head for more than a short period of time. The most common causes of high head pressure include high load, overcharge, and poor heat rejection (such as from dirty or obstructed condensers). One response to “Do Line

Worked in the business for a lot of years. This is one of the things that aggravated me the worst, poor installation. This unit never had a proper installation or start up done.
