I'm not an HVAC guy. A while back my wife asked me why I watched you, and I told her it was because it's always worth watching a good teacher teach. Fast forward, couple days ago the AC went off in my house so I started with the big picture, grabbed the ammeter and figured out the compressor wasn't running, checked for and found voltage at the contactor, checked the compressor for short to ground (none) pulled and tested the capacitor and found it bad. $18 later for a new one and my AC is up and running again with no service call. Thank you sir!

[@wolphin732]

[@Colt-wr6wx]

Yes.. and I love it. Lol gotta do it right the first time

[@jordanhenshaw]

But only to have the entire unit be replaced a month later. I did that a couple months ago and the unit was replaced a week later, lol.

[@user-sas._.]

My house has this exact rtu. Total hackjob, horrible intallation, wires are a mess, 3rd party condenser fan, and beat up condenser coil. Before i rented that house i saw how it was remodeled when they replaced the swamp cooler and installed the 20 year old used york unit. landlord doesnt care if anything happens to the house once there was no cooling called the landlord but i got no response but bakersfield heat is no joke so my only choice was to fix the unit and thanks to your videos i diagnosed it and replaced the contactor, capacitor, redone the wiring and cut off the heating because that heat exchanger was sketchy and it doesnt get that cold here anyways.

[@SOU6900]

Ok the fact that you can read your meter remotely through your phone is amazing

[@InconsistentManner]

That York unit is from Norman, Oklahoma and was Manufactured in November of 1998. They still make a similar version of this model to this day. I know this because I used to work for Johnson Controls before York was bought out and became a subsidiary. I worked four years from 2002 to 2006 and a family member still works there to this day.

[@Bryan-Hensley]

They made a Coleman version of it too. Or basically different stickers

[@fredflintstone8048]

Eat before you're hungry, and drink before you're thirsty. Once you get behind it's too late, you can't catch up during that day, especially if you remain out in the heat. Take it from someone who lives and works in southern Arizona where these kinds of temperatures are normal every summer. It's a normal way of life here. Dehydration also has an effect on your ability to think clearly.

[@MrGamerholic]

Also remember to keep your electrolyte levels up. Look up water drunkenness due to electrolyte imbalances.

[@thomashines8]

In Iowa as a tech I live off Liquid IV, Gatorlyte and Body Armour. I promise it’s worth it at the end of the day. We get 100 with 80% humidity. Absolutely brutal.

[@rustblade5021]

yeah those hats are great, i've got a few. also instead of a cold towel around neck, dunk your arms in a bus bin of ice water. also drinking a slushy or something like that before going on a hot roof helps immensely

[@44R0Ndin]

If it gets truly nasty outside (or you have to work in an un-conditioned attic), they make "cooling vests" which is a simple vest with a layer of insulation on the outside and a multitude of mesh pockets on the inside, and inside those mesh pockets you put gel cold packs. Sometimes they are a little too effective, but the key thing to know is that they cool your torso, aka the core of your body, and that's the most efficient place to apply cooling because your body already has a "coolant" system in it, in the form of your blood, arteries, and veins. That's also why dunking your arms in a bus bin of ice water is so effective, your blood rather quickly transfers the cooling to the rest of your body.

[@gregdennis3523]

Wish I was young. I would definitely have enjoyed working in HVAC! The rewire looks amazing!

[@markae0]

@ 7:42 (later on) Someone downstairs- ground level sees the fuse box " Hey this fuse is turned off. I better turn it back on!" and you on the roof have bare exposed wires that you are wiring to a new disconnect. I hope you padlocked the door to the fuse box. Great VIDEO!

[@awesomestuff9715]

Usually you don't lock out the entire panel, instead you have a lockout on the specific breaker(s) that you are working on

[@HVACRVIDEOS]

Yes it was locked out

[@Farm_fab]

Chris, I used to work for a maintenance contractor at a food manufacturing company, and one of my coworkers took Gatorade up on the roof, and kept it cold in the run off from the AC units, in a bucket. He got in trouble, but not for long, when the safety manager told my boss that anyone working on the roof needed adequate breaks and needed to stay hydrated. Keeping his drink cold was a good idea. I've used that water to help wash the inside of locked out units that couldn't be pressure washed, since water on some areas of the roof was on the front side of this massive roof, and no one wanted hot water on a hot roof, even though there was a bit of an advantage to warm water for cleaning.

[@tedhicks5431]

Sux to have to run 400 plus feet of water hose no pressure

[@tbelding]

You have to watch out. If you're running REALLY hot, you don't want any drinks to be lower than cool, preferably lukewarm. Really cold drinks can cause colic, basically. Tie your guts in knots.

[@tedhicks5431]

[@_iLLuSiv3_]

The most important and best fix for a York is to push it off the roof!

[@hrdworkin7633]

I'm sure someone else commented but the unit is single phase and amp draw usually higher than 3 phase. be careful in the heat.

[@tonyking9235]

YOU WONT NEED TO WATCH ENEY ONE ELSE . GOOD MAN IS CHRIS

[@Starchface]

When you discussed having the manager call your guys on the roof it got me thinking. If you were alone up there and had an accident or lost consciousness in these conditions, it could be curtains. Be careful out there. The last thing you want is the manager finding you on the roof the next day.

[@buixote]

"Shake that Booger"! Sounds like disco! You're probably too young to remember, Chris! ;-) It's inspirational to see you "lose it", and polish the Turd!

[@mysock351C]

Regarding the wire size, fwiw starting the compressor is what it usually needs to be sized for due to the inrush current, which can’t really be measured on a DVM due to the short duration. Combine a long run with sagging line voltage and the compressor might not start. Used to do the MEP design for PETCO years ago, and they had a 110V reach-in fridge (can’t remember who made it) for their aquarium department, and in certain stores they would all end up nuking their compressors after a while. Turned out the compressor would intermittently fail to start at times due to the excessive voltage drop with normal 12 AWG wire, and that was what kept killing them. Had to retrofit all the stores with either 10 AWG (or 8 AWG for long runs) to stop them from going locked rotor at start-up. Edit: And yeah working on roofs in 100+ degree heat really sucks. Hated that.

[@jhill.7216]

[@matthewrichardson2467]

Can't imagine working in that heat! Nice you have a plan to stay cool and good idea getting the manager to check on your team when they're on the roof! I just imagine when you send them an invoice for a new disconnect, evap fan motor, rewire and R22 they'll go "Hmm this unit is costing us lots in repairs, Lets replace it next week"..

[@44R0Ndin]

Especially that R22, like Chris said that stuff's "liquid gold" because they literally don't make it any more, what people have stashed away is all there is to use.

[@GeminiSeven43]

Great job Chris and thanks so much for going the extra mile on that wiring. Looking at that mess makes you cringe and now it will be easier for anyone following you to check for problems and you can leave there knowing that the "Dumpster Fire" is a little bit better. Thanks for taking us along.

We've got the same policy of checking on reefer techs when we do a roof job any time of day during summer. Dispatch will call us and make sure we're ok, taking breaks and staying hydrated

[@salvatoreluciano864]

Probably a good idea to run your continuity/short to ground test BEFORE moving wires around.

[@retrozmachine1189]

These days you don't need to be a genius electrician if electrical isn't your trade. There's a good selection of web sites that will give you a good idea of what wires you should be running. Plug in your expected load, run length and other environmental considerations and they spit out regulation compliant recommendations. Note, it's a recommendation only. It's still up to the tech to make the determination to use that recommendation. Of course, only do electrical if you are permitted to do it.

[@gregmercil3968]

I’ve work on a few Yorks like that one, and it’s newer than you think it is. This one was manufactured 2003. That 2 pole contactor to the left is for the draft inducer, which is never used but the heat isn’t hooked up. Seems a bit overkill to use a contactor for that little inducer motor. 😂

[@thehappytexan]

I’m not an hvac tech or electrician, just a guy that researches projects before doing them. When you said they ran #8 wire on a 100’ run for a 60 amp circuit, I started shaking my head. There are simple charts that show what is needed for a given amperage over different distances.

[@Alexelectricalengineering]

Nice fix of the wiring, I would agree that the wire should be 6 AWG

[@smithno41]

I didn't see him tag out lock out the breaker before he started installing the new disconnect. Maybe I'm paranoid, but if I can't see the breaker from the place where I'm working, it gets locked out.

[@HVACRVIDEOS]

It was locked out, I actually locked the entire panel shut

[@HappilyHomicidalHooligan]

It doesn't matter what you actually run at, you MUST size the wires for the Circuit Breaker/Fuses protecting the circuit modified by the ambient temperature and circuit length (they each derate the circuit requiring a larger wire size to compensate for the wires reduced current carrying capacity - hot wire and long wire runs can't carry as much current as a shorter, colder circuit)... Depending on just how hot it CAN get in summer, I likely would have gone with a 4 Gauge wire for a run that long (unless the NEC specified a 4 Gauge to begin with, then I might have gone with a 2 Gauge)...just in case the area got a record breaking heat wave, I don't want my circuits to overheat and either blow fuses/trip breakers or catch fire...

[@jrmcferren]

Air conditioning has special rules. You should do the ambient adjustment, but the wire for air conditioning is sized at the maximum circuit ampacity. The breaker is sized based on this figure or the largest breaker and fuse marked on the unit. You may size the wire based on the fuse and breaker like normal, but you are allowed to use the ampacity figures. The reason you are allowed to do this, is the air conditioner has overload protection and that is figured in on the minimum ampacity. The breaker or fuse can be sized at a higher than normal value for the wire size because the breaker or fuse is only providing short circuit and ground fault protection. Simply the overload in the AC protects the wire (and the AC) against overload, the fuse or breaker protects against shorts and ground faults. Mike holt had a video on this.

[@HappilyHomicidalHooligan]

@@jrmcferren This is basically what I said, Chris mentioned the System had a Minimum Ampacity of 45 Amps (I think, somewhere around that) but had a 60 (or 70 Amp) fuse in the on unit disconnect and 70 Amp Breaker in the local Panel. According to my comment, that means that regardless of what the Minimum Ampacity listed for the Unit is, the wires MUST be sized for the 70 Amp Fuse/Breaker ACTUALLY Protecting the Circuit derated according to the ambient temperatures found at the location and length of wire run...

It is with most specialized tools and even more so protective equipment (Sun Protection, Eye Protection, Hearing Protection,...). The stuff you can just grab will be more likely to be used than the stuff you need to go and get.
