KITCHEN AC IS BLOWING HOT AIR 

Thanks so much bud! I dont know everything and there are many other techs out there better than I

I work in Ventura County and there is a huge shortage of technicians. Any company out here would die to get a hold of you. I own a very small company and technicians like you are very few and far between. Keep up the good work!

Chris you know why they say you are the best, its your attitude towards problems and your editing style is really good and through and easily understandable explanations of why you do things the way you do. Lately I have always been hearing in my head while I'm working away you saying "look at the bigger picture" lmaooo anyways thanks for all the hard work to bring us these videos

well there is no doubt, i have learned lot from him. he is the best

Yup his and hackfreehvac are the only 2 channels I consistently watch .. invaluable information

SGTGS I was thinking the same thing. A chest or head camera would be better.

Head cam would be better for us, we would automatically see whatever he's looking at as he's looking at it...

Yeah that would be nice for us but it would be a lot more editing and storage requirements on his end.. I'd rather have more videos than the better perspectives if it's a choice

@@jojomorgan8556 Not really, we are talking about replacing his tripod mounted camera with a chest or head mounted one. Same amount of video for Chris to edit, but his work would be much easier due to having both hands free while filming... We would also get better viewing angles since we would be able to see things from Chris's perspective without Chris making a better door than he does a window (no Insult intended Chris)...

@@HappilyHomicidalHooligan you must think he leaves the camera on constantly like a head or chest mounted gopro usually is.... I don't think he does... it would be more recorded footage due to the cam being always on ....

Thanks

No doubt. Luckily our company has a hilarious emergency call rate that keeps most of these at bay. One such occasion is that I had to go get 2 security cameras back online, only to find out once onsite (1.5 hour drive one way) that they had been offline for over a month. I guess their daily checks aren't so daily.

We used to get this all the time when I was a telco RF tech. Landmobile customers would have something fail on Tuesday but call it in 4pm Friday as they were leaving for Pizza, demanding it be fixed by Monday morning. I got paid overtime, but a 200 mile round trip against weekend traffic (all the shitty drivers come out to play on weekends) used to irritate me.

Whoa! Hey man! I havent seen a video from you in a long time. Long time fan! Hope all is well! Crazy to see you on this channel for some reason. lol

@@mq1991 LOL ya, I seem to bump into my fans on various tech channels a lot. I guess it just means we all like the same stuff. For the past couple years, I've been having to work a lot more than I used to in order to keep up with the rising cost of living. So I haven't had much time for hobbies. RU-vid has also gotten so strict with copyright stuff that I can't use random music and video clips that I enjoy to demonstrate equipment anymore. It's taken the fun out of making videos.

Great point, I will be going live on RU-vid this evening 11/25/19 @ 5:PM (pacific time) to discuss my most recent uploads, and answer questions from email’s , RU-vid comments, and the Live chat come on over and check it out if you can. ru-vid.comlive

Could be hail damage...and old age.

If you think this unit is bad, my cousin worked at a Burger King, and they got the AC units replaced because they were shot. When the units were lifted off the roof with a crane, they literally fell apart like a cartoon. Every panel popped off and the guts of the units rolled off the flat bed going everywhere. If that wasn't bad enough, the newly installed units didn't work.

Man I don't know what it is with RTUs but they do get beat to hell. I work at a movie theater built in 04 and the RTUs are already worn more than logic would imply. 3 story building, no trees or anything else around, very limited roof access to personnel, and yet they just look like someone took a baseball bat to em.

Banged up likely from careless service techs I’ve discovered removing & mis-handling panels ... They have been know to also cause roof damage / leaks by this improper handling by drop corners on roof to end up cutting the roof materials ... Customer ultimately calls a roofer when it was likely actually caused by the initial careless hvac tech 😩👀😤

Nothing a little bit of maintenance couldn’t clear up. Some emery cloth to remove old grease and corrosion, some penetrating oil to lubricate the pivot points and dried grease, and new grease on the knife blades. 5-10 minutes of work and it would be fine.

John Sharkey same! Southwest florida!! 👍🏽

@@angelomacareno5392 who are you with?

John Sharkey modern services at the moment. Been with them for over 5 years.they’ve allowed me to get my hands on refrigeration and I’ve watched Chris for about 2 years and they’ve helped me a lot!!

@@angelomacareno5392 Yep I like the big picture diagnostics. I know a few guys who used to be at Modern but are elsewhere now. Im with TWC.

I will be going live on RU-vid this evening 10/14/19 @ 5:PM (pacific time) to discuss my most recent uploads and answer questions from the LiveChat, RU-vid comments, Emails, and Facebook comments come check it out if you can. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tB11ZTSHhhE.html

Dielectric grease is the Vaseline looking paste. It's job is to prevent further oxidation / corrosion. Your suggestion of scotchbrite is better than the idea of putting dielectric on the hot contacts. Scotchbrite will remove the oxidation, lower contact surface resistance and the excessive heating seen as a result. Dielectric is for use after the fix, not a fix in itself.

IncandescentWithRage exactly it’s for after the fix itself. We used that grease on the contact surfaces for distribution breakers plugging into 1200+amp bus bars. The aluminum was a whole different story. Penetrox is nasty stuff 😂😂 I got hazed a lot by a guy that wouldn’t let it go after I was there for a year. Dumped a pint of penetrox in his toolbag. Never messed with me again 😂😂😂

IncandescentWithRage all the stuff we used was from DOW. I think the part number for the grease was 111 can’t remember.

NEVER just "Replace the Fuse/Reset the Breaker and just see what happens"! Fuses/Breakers blow because Electricity is going somewhere it shouldn't be in a hurry (Short/Ground Fault/Dead Short) and that is going to either damage equipment, start a fire, Hurt/Kill someone or some combination of All-of-the-Above! Always use a Circuit Tester/Multi-Meter to find the problem before Reseting the Breaker/Replacing the Fuse... I speak from Painful Personal experience, an "Electrician" reset a Breaker without finding out why it was tripping at a place I briefly worked and I got tossed 15 feet. I rested my hand on the case of a Deli Slicer as I turned it on (my way of making DAMN Sure my hand was nowhere near that blade) and it had a Dead Short in it...I got tossed 15 feet and ended up in the ER for observation, the breaker blew again, the slicer got even more damaged from the internal arc and the Idiot "Electrician" got fired for Negligence...

I finished school in June 2019 -- they tried to make things as hands-on as time and curriculum would allow-- but while you're in school just absorb what you can. The hands-on is waiting for you in the field in huge amounts!

History ... Also, I limited (no longer in the biz now) my run time without the panels in high ambient temps. In the old days of belt driven compressors (which I had my share of repairing and replacing with Hemetics), the motor's heat energy was not mixed in with the freon, so high temperatures and moisture levels were manageable and at worst resulted in frozen TXVs. Once we combined the high temps of compression + windings within the same shell, the reaction of H2O and CCL2F2 (R12) started to create HCL and there were a lot of early compressor failures due to the lack of proper understanding of dehydration and the acidification of oil. Those earlier guys I worked with used old refrigerator compressors as vacuum pumps or simply purged out the air. It was thought early on that the Hemetics were the failure point. But once compressor manufacturers starting analyzing compressors coming back for warranty replacement, they identified the acidification of oil issues, and the industry responded with better training methods of dehydration and 2 stage vacuum pumps, micron-meters, changing filter/dryers once opening the system, limited exposure time left open. When I taught HVAC I no longer referred to it as "evacuation" but instead used the word "dehydration" as that in fact is what we are doing. Anyway, long way of saying, minimum time of that compressor being exposed to high head temps saves oil life and seized compressors down the road. It's good to watch someone like you who understands what he's doing and not just swapping out parts. So many of the field techs who came in for my classes (usually sheetmetal HVAC guys) had no understanding of what they were doing from an analytical standpoint.

Thanks bud!

Low suction could have been the bad motor bearings and pulley+belt, and don’t forget the return grills. Slightly high head could be the condition of the unit as you said.

Thanks Chris! I sent you an email on the same topic too 😉

Arc flash is no joke, at best it's a good way to make you feel like your eyes were sandblasted, at worst it can kill you. Never seen one in person, but I have seen the videos. It's literally a constant explosion fueled by electricity. Some rocket engines use this phenomena to heat propellant, they're called Arc-jets. Mostly it's thought of as a low-thrust system for propelling satellites in the vacuum of space (too much power needed to create enough thrust to push something off the ground, but just putt-putting around in space is easy with a few 10s of kilowatts of solar power). The best part is that you can use just about any liquid as propellant, provided it won't freeze or boil in the tanks and is somewhat chemically neutral. I think there's a company designing one that runs on Water, but you could use Ammonia or Hydrazine if you wanted a little more performance per kilogram of propellant.

Thanks!

It's not exactly a brilliant setup, but at least there actually is a fuse and a disconnect. Sadly stuff is either imported or so cheaply made that it hinders the progress of safety around electricity. You could get safer systems, but it would cost you more money.

Basic Electrical Circuits are simple. Just remember, power must always return to the panel for a Circuit to work properly [leaves on the Hot (Black) and returns on the Neutral (White) for 120V circuits and leaves on Line 1 (Black) and returns on Line 2 (Red) in 240V circuits]. Remember that and you should be able to use a good How To book/You Tube video to wire any circuit in your home safely and to Code (If you're the Home Owner, get a Permit from the City and the Inspectors will insure that it's done Legally and Safely)... It's when you get into Programmable Logic Controller (PLC) and/or Relay Logic circuits and 3 Phase Motor Control that it can get confusing...

We need all the help we can get in this trade I will discuss your question on my Livestream tonight , I will be going live on RU-vid this evening 12/16/19 @ 5:PM (Pacific Time) to discuss my most recent uploads and answer questions from emails, the chat and Facebook come on over and check it out if you can. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_20hGnjjK44.html

@@HVACRVIDEOS thank you I'll be there :)

It's a temporary solution to the disconnect knives not making connection. I personally feel that the grease will attract sand and cause more problems in the long run

joel watts the points are what give contactor s the rating. When the points which are made of silver get pitted the contacts can arc closed or give a bad contact. Changing a contactor beats the shit out of changing a compressor.

Yeah I am definitely crazy

Correct me if im wrong, but if one leg was stuck closed, you would have 120V on that leg. If the other 2 legs were not energized, then there would be 0V. Therefore, if you tested voltage from the stuck hot leg to the other non energized leg, you would read 120V.

@@Edward-ud8hd You are right on the 120v part, but not on the energised to not.. Let say that phase 1 knife make contact, but not 2 and 3. 2 scenarios. First, fuses are intact. Phase 1 loop throught the equipment and back at the fuse 2. Fuse 2 therefore read 120v at phase 1. Voltmeter see 0v difference. Scenario 2. Fuse is blow. 120v phase 1 is present at the bottom of fuse 2, but can not reach the top. The phase 2 knife is open. Therefore, the top is floating and no current can flow. Meter still read 0v. In both case, 120v is present. We have both scenario here...

You really need to test both phase-to-phase and phase-to-earth - there are scenarios where only checking one is unsafe (eg only checking phases-to-ground with a bad ground)..

@@ickipoo a bad ground in such setup is very improbable, close to impossible due to how and where it is installed (indirect ground in multiple location) bit not null, so yeah, you are right.

@@thephantom1492 I agree, but that's the problem with Internet advice - someone can take it, and apply it in another context (say, a disconnect in another location), and come a cropper.

Roy Amberg I always check voltage drop across fuse while unit is running, anything over .5 to 1 volt and that fuse is getting replaced regardless off continuity check with fuse removed.

@@m0fr3sh90 you didn't get what I was saying. You can ohm a fuse and it will ohm fine. Once you put current on it it opens up. Example. Single phase system. No power after fuses. And power before. Disconnect is on so fuse will show open with a volt meter. Turn power off it ohms fine. Had this happen before. Several times

Roy Amberg gotcha
