Trane evaporator was leaking refrigerant and needed replaced on this packaged unit. Some viewers have been asking for me to not edit out the brazing, problems and real life service issues we have... so I left it in. I'm curious how the video will do.

For any RTU data plate that is blank, take a sharpie and rub it on your thumb and then rub it across the data plate. The lettering is slightly lifted on the sticker so that sharpie will rub off on the raised letters and allow you to read it again

The old timer who taught me the basics always told me to " re-cook" the copper before swaging . The little spin-swage bits that go in the drill don't split the copper because they cook it from the friction .

@hvac01453 Жыл бұрын

I noticed you have the same swaging/ flare block kit I had in college @ 26:40. Every tool has its place. When I get in a tight place where theres no room or abosolutely cannot slit the pipe or it will screw me all up, this is my goto tool. It NEVER splits the tubing because it doesn’t try to stretch the whole length of the tubing at once, but rather in increments. Ihave several, and use my yellow jacket monster pair most often but it splits tubing rather easily if you dont rotate it often during the stretch, i often use it to repair fitting that dont seem to fit ok of have a touch of solder in them or trying to re-round out a compressor connector that was damaged in shipping.

@coltonmoore1 Жыл бұрын

I’m pretty sure you accidentally left your manifold open on both sides, which is why your gauges were reading almost the same pressure on both the suction and the liquid side (as if the compressor wasn’t running) even tho it was. So, the refrigerant was just being passed through the manifold on the gauges.

With electronic gauges of any type (mostly I'm experienced with multimeters and other kinds of electronics), they can be REALLY picky about voltage. If that battery is going iffy, even if it shows a half or three quarter charges, replace it. Even a rechargeable lithium-ion is only really good for about 500 charges, and that's if you regularly run it down to the bottom and back up again. (5-10%) I don't know what kind of batteries those use, so I can't make a suggestion about a good one to keep as a spare in your vee-hickle.

I was gone 2.5hrs on the other call with those big 3/4" vac hoses pulling down with the 8cfm pump, I can normally hit a perfect vacuum with a compressor in the circuit in 30 minutes or less. Whos to say the refrigerant didn't have moisture in it or was fractionated... so I'll be strait, I did not verify the microns. I'm a horrible person....

Rick love your videos but (there is always a but) you used the incorrect name for your flame type you use. At time 20:53 you can see clearly 3 flames, the outer (some call the envelope), the middle cone and the inner cone. This is called a carburizing flame. It looks to me as a 1x carburizing flame (the middle cone is equal to the inner cone if the middle is 2 times the length of the inner it is a 2x). When you were annealing the copper so it would not split that might have been a oxidizing flame that is very hard to tell from the video. Also the soot you wiped off the dryer was because you used a carburizing flame. Do not get me wrong I also use a slightly carburizing flame when welding on aircraft. We were told to use slightly carburizing flame so we would NOT be accidentally using a oxidizing flame which in some cases very bad! In aircraft we only use brazing on fuel lines and such and they were mostly stainless steel. So when I braze copper lines I use a slightly carburizing flame as it is easier to see and keep.

Auto mechanics use it because they're not air conditioning technicians. Hear me out... Air conditioning is just a touch of what they do, they don't specialize in it, sure they understand how it works and have the MAC card, so do I 😳. Car mechanics usually have a all in one machine they hook up, punch in the numbers and it does all the work otherwise they change parts that were already predetermined by the factory. They don't find a different brand of part to fix a problem or redesign it. That's a Huge difference, that's not too dethrone them or devalue but to just state facts they are mechanics that are good at fixing a shit ton of cars problems but that is totally different than just a dedicated hvacr mechanic that works on everything under the sun multiple different facets in the mechanical world.

Dye absolutely increases our productivity and we're probably going to start selling it on tune ups, costs us $5 a shot.

@@HVACRSurvival I was a mechanic for 7 years before changing careers to residential HVAC. I specialized in MVAC repair and diag. The dye I have always found less helpful than you'd think, usually you have to break out the leak detector or the big blue and a lot of times even that's not enough to find leaks, so you end up evacuating and leak detecting with nitrogen. It's pretty similar to residential HVAC. What sucks about MVAC is there's not a lot of help with superheat and subcool numbers to help you diagnose, and there are only service ports on the suction and discharge usually. Even if you could measure SH and SC accurately, there's so many variables like blower speed, engine speed, engine fan speed, ambient temps inside and outside the vehicle, mode settings, engine temp, etc etc so you end up trying super hard not to just guess and fire the parts cannon. Manufacturers generally only publish charge weight, oil volume and MAYBE target pressures at a certain RPM. MVAC could be ridiculously frustrating sometimes, even with the fancy all in 1 recovery machines haha
