Good advice on shocking your body with temperature extremes. I learned the hard way during a high school band trip to Florida (December 1995). We had been practicing marching technique in a parking lot on a 90-degree day, required to wear long pants and long sleeves to protect us from the sun (which wasn't a problem in similar temperatures during our summer practices, but nobody seemed to figure that out). No matter how many times I alerted drum majors or staff that I was experiencing dizziness, difficulty breathing, coordination issues (I actually tripped over my own feet and fell with my snare drum breaking my fall), I had progressed from sweating profusely to shivering cold with goosebumps, and all my complaints fell on deaf ears. When I complained that the blue sky was orange, the parking lot was burgundy, and people around me looked pale blue in color, they finally took notice. Practice was cut, and we all returned to the charter buses that had been sitting for hours idling with the AC on full blast. The shock to my body was incredible. I had stomach cramps, extremely painful muscle cramps, nausea, and at one point I began complaining about how hot the bus was while returning to a profusely sweating state, until finally my core temperature returned to normal and life went on as "normal." It took three hours before my body would accept any beverage without promptly ejecting said liquid the same way it had been delivered. Good to know you are taking the necessary precautions to prevent/mitigate any heat-related health concerns. I have profound respect for techs that can be up on a roof for hours, not only do you get blasted by the sun, you get the heat radiating off the deck. Also good to see businesses shifting to white roof coatings over the years - once (AND ONLY ONCE) did I re-tar a flat black roof of an auto shop I worked at, and man, it was hell. (Especially when I almost fell through the rusted-out corrugated steel roof from the 1960s that had more leaks than it did intact portions - every time it rained we had to squeegee out the service bays and dodge puddles/drips while working. It's hard to detail a Mercedes E-Class when rusty water keeps dripping onto the paint!)

Wondered that myself. On all those YT videos I have seen more wiring looking like a rats nest in HVAC units than tidy ones. Especially as soon as some one worked on the stuff.

[@chemech]

The dull, serious answer is that in the unlikely event that one of these units were to catch fire from an electrical fault, the locations are not going to cause an immediate threat to life & limb.... Lower threat level leads to less thorough inspection standards, if things ever get inspected at all...

Hi Chris, That's impressive how you handled that day's work, and how planning pays off. I will often stop and eat if on the way to site later in the day, because once on site, one does not know when one will see food again. The EZ up is a game changer, and it's not bad to take it with and putting it up. Any extra comfort makes it easier to concentrate on the job and do quality work. I was up on my dad's roof sealing roof nails today as all the seals have failed, it's a flat metal roof. Had the right sealer and brush to apply, so it went well but man was it windy up there as we are not done with the snow for the season here, so it blows up a gale the few days before it snows to the south and we get what's left over as rain here in the central parts of South Africa. Nice one, I enjoyed the show. Best regards, Duncan

A roof in the valley on a hot day is just as bad.

[@Straycurrent]

Great video! I really appreciate your follow-up discussion and review of strategy -- in planning the job ahead, rounding up the materials in advance, and the way you go about executing the plan in such extreme heat. Without that kind of prep, a tech could reach his limit early in the job and then start taking shortcuts to wrap up and get off the roof as soon as he could. And the quality of the repair would be compromised. Thanks for all the good advice.

Unsolicited suggestion: if there's a section where a wire has arced through to the metal frame, use a paint marker to circle the arc mark - that way the next guy knows someone has already found that, it's not new news.

[@44R0Ndin]

I take it you guys just flat out don't do attic work in the summer? 160f is literally hot enough to cook the salmonella out of chicken. So sending someone up into that without measures against the heat is basically a death sentence unless you only stay up there like 5 minutes at a time and then a half-hour break to cool off again. NASA has a solution for that, before you put on a space suit you put on what's called a liquid cooling garment which is basically a spandex long sleeved shirt and spandex leggings with small tubes sewn in to it that circulate water that is run thru a block of ice (ice sublimation chiller) in the space suit backpack. Could do something similar for use in a hot attic, but you'd have to swap out the ice sublimation chiller for something that would work in earth's atmosphere, probably just a cooler full of ice water would work. That's too heavy for space but it would work perfect on the ground. If that sounds too complex, you could make a suit that holds a bunch of those gel ice packs next to your skin (most importantly on your belly and your back, as that's where you would be able to keep your core temperature down) but you wouldn't be able to control your temperature as easily as with the liquid cooling garment where you could just control the speed of the water going thru the tubes to control how much cooling you get.

[@Bobby-cm7vu]

120 damn, I'd die in that after a few seconds

[@chemech]

I've spent a lot of time in steel mills - specifically, the meltshops where the furnaces turn scrap into liquid steel. Heat stress and dehydration are extremely serious problems, and you need to be drinking a half-liter of electrolyte drink (Gatorade, etc) no less often than every third half-liter of fluids - i.e. 2x half-liters of cool water followed by a liter of electrolyte drink. At 120 F [49 C], alternating every other bottle is a better idea, and some of my clients insisted on that. Food helps control nausea from pushing so much liquid through your gut. But, you also need to be careful... Blood sugar management is also an issue, especially as we age and some of us develop Type II diabetes. You'll be getting sugar with your electrolyte drink, and you'll be burning some as you are working, You have to balance that against your food intake, and lean protein and vegetables, some fats & oils, and light on the carbs is the way to go. Work slow and at a steady pace, and take lots of breaks - 5 minutes every half-hour is not a bad starting point,,, the Dept. of Labor's minimum of 15 minutes ever other hour is not suited to working in the heat... If you feel tired, dizzy, or even unfocused, you are already in the yellow zone, and need to pause and catch your breath. Watch your hydration - you should be drinking enough fluids to be urinating not less than every other hour. Check the color of your urine - there are color charts out there on the 'Net... pale yellow is good, too dark is bad = dehydrating, white to clear might be a warning of too low of an uptake of carbs & electrolytes, so think about what you are doing. All of this goes double in a humid environment. You do not want to be feeling ill and lethargic, and there isn't all that much reserve left from there to needing hospitalization - which sucks big time... And, every year, we lose a few people to heat stroke - usually guys who tried to tough it out, where this time their bodies just couldn't bounce as well as before...

[@etherealrose2139]

Color of urine doesn't determine how hydrated you are. Certain foods and medicines can alter the color. And I can drink 2 gallons in the desert without a single piss because... it evaporates via sweat and breath. And if I do pee it's just a little and dark due to evaporation before hitting the bladder. But I can assure you I am more than amply hydrated. TA-DA! So don't hand out false information. The desert is a different beast than any other climate. Act accordingly

[@wiiyaasiniini5323]

I have had a lot of trouble with those black valve core removal tools that you used. They tend to leak at the ball valve stem making pulling a deep vacuum/passing a decay test challenging. I like using the brass gate valve ones whenever possible, the only problem is they don't have a micron gauge port.

[@cranbers]

I don't understand why in commercial install they wouldn't by common practice you wouldn't put some sort of protective or sleeve on wires, especially if they come near metal pipes or any metal for that matter. Wires laying against metal, it can get hot or vibrate so it will cause wear over months and years. So why isn't common sense in place ?

If you're gonna be working somewhere for more than a couple of hours, it's always worth it to bring stuff that makes you more comfortable. If you're constantly thinking "jeez it's hot, I wanna get out of here", you're way more likely to make mistakes, or to ignore something small (like: It's too hot to worry about that wire not being perfect).

They’re not going to do any PM for a year, by that time the unit is expected to be eol, so its a waste plus another potential leak. You notice the unit wasn’t sprayed blue for bubbles before being blessed by the Scotch vicar.

[@hvacslayer2929]

Sporlan actually has a drier/sight glass combo I use them on fresh split installs, but technically comfort cooling you don’t need a sight glass if anything it would be for oil levels on the compressor.

[@raymondjacobs8429]

You've got to try Heat Shrinks, looks better then Black Tape.

[@jamesr2888]

7:31- 7:45 I know exactly where this is & what business you're at. ;) No I won't tell.

[@erickhines4121]

Keep those R22 units going. Nice work 👌

[@Joniyah444]

I swear r22 runs cooler, better, less fussy. Better temp difference

[@chrisduhaime5689]

It's more forgiving on the charge amount R410 is more critical on the charge amount . It doesn't take much to over charge with a R410 system the other thing with the blends if there is a small leak got to remove and recharge with fresh charge can't top off because the blends is out of wack the pressures can look right but not be working very well . Now the industry is try to go to butane . Very flammable.

Noticed that we have a few of the same tools and equipment!!!! Which is awesome! It's like Seeing a player on your favorite team and having the same cleats. Lmao!!!

[@Ted_E_Bear]

Man take care of yourself out in that heat ! Great video !!

[@starlite528]

heat cramps, heat exhaustion, heat stroke. very serious conditions and you're right; it's easy to forget to check yourself. I was in the army for ten years, and they take it very seriously!

[@MAZA4lyfe]

Dang 350 psi on r-22 and 225 discharge. That poor thing. How long would you expect that thing to last if it ran like that for a week?

[@matthewgregory8218]

You guys have a dry heat as well right ? Condensers work harder farther south then an Atlanta climate where you get summer and winter ?

[@More350Power]

The heat is no joke for sure. Ive gotten sick from it before 106 degrees high humidity, south carolina, out in a salvage yard. Even though I kept hydrated it had me sick for almost a week. I thought I can keep going.... yea then the vision goes blurry..... not good.

[@siemenstraffic]

Kind of interesting than R-22 is still allowed to be refilled in AC units in the United States. Since the Jan. 1st 2015 no R-22 can be charged into any system in EU/Europe , what-so-ever, being virgin, recovered, recycled or reclaimed.

[@Michael-pi2be]

I don't think there are any strict regulations in the US. I do know r22 manufacturing stopped earlier this year. It's gonna be used for a few more seasons yet

[@Stars11222]

we are no longer able to manufacture it, import or export it, we have reserves but once those are gone then thats it so at some point its going to become too expensive to get or even find it and that will force people to upgrade but as of right now the reserves are being slowly used up

[@HighestRank]

Looks like it’s time for all of EU to purge their units and export it to the USA.

[@ninamcclure2193]

Crazy heat, over here on the east coast u get the humidity that sucks the motivation right out of u. I took my name off this account and I'm going to start my own soon. Used to be miles and nina... thx for the great video guy.

Question: What is the most flustering unit you have ever worked on? :-)

[@arish00]

So Chris, I'm curious what you do with all the scrap metal and old parts, such as old worn out Compressors, old worn out Electric motors and filter/driers and copper and so on and so forth??

[@HVACRVIDEOS]

I will discuss this on my Livestream on KZbin this evening 9/20/21 @ 5:PM (pacific) come over and check it out kzbin.info/www/bejne/fXmmp6aGhqiIZqs

[@georgioskambourakis]

Thanks that helps alot

[@ehsnils]

What I think is a bit amazing but not amusing is that it's OK to have the electrical wires just free-hanging like that with no outer sheath and no dedicated routing. I wouldn't let that fly if I made an electrical review of those units, but that's me, I have some OCD when it comes to electrical and like to see professional equipment for outdoor use to be at least IP67 (protection from contact with harmful dust, protection from immersion in water with a depth of 1m [3.3 feet]). IP65 might do too, but that's about the limit I'd like. Or do I have too much OCD on that?

[@alexku8452]

My first instinct would be to cover those loose wires in this flexible wrap around conduit whatever stuff. Bundles them up nicely and gives some protection from rubbing through on anything. And seeing the wiring he wants still to tidy up, I was very much missing a grommit when I saw those cables laying on the edge of the sheet metal. Within those units you do not need to go overboard with IP rating. I would say IP44 would be fine as everything is covered more or less. Only thing I would be worried about would be the fan motors and wiring. but then with those connectors on the single wires, even with some water ingress, it is very unlikely anything will short out. I wouldn´t dare to touch it though when it is wet. And also I would most likely try to get connectors or at least part of the wires in a downward loop. This way any water would drip of the loop. I those wires get too soaked, especially with the connectors on and maybe tape around, I have seen water beeing pulled through the cables strands of wire due to the capilary effect. May end bad depending on where the other side of that cable ends. You may soak water directly into a connector on an electronics board. But then, with most electrical components, some water or moisture would not do a lot. It may short out under certain circumstances, and it will corrode your contacts for sure. But it´s not like the cables for example cannot handle some.

[@erikkovacs3097]

How high can the ambient temperature get before an AC gives up? 130? 140?

[@TrekkerMoto]

Shouldn't really "give up" just not bring it down to the same temps. I never did commercial or residential a/c, but I did cars. Rule of thumb for cars is the a/c can get down to around 40 under ambient so when you get to 130 degree ambient, absolute best we would ask for out of it would 90 degrees, but those are also a lot smaller systems and cars are not really insulated. I would take a guess that on a commercial system, as long as the building is insulated well enough, you should be able to keep your temps in the 70's no issues even up at the high temps. This is assuming a correctly sized system for the space.

[@erikkovacs3097]

@@TrekkerMoto Eventally the high side pressure gets so high that some protection device kicks in either in the compressor or some high pressure switch. The question is what temperature does that occur?

[@44R0Ndin]

@@erikkovacs3097 The answer to that depends on what pressure the high pressure control is set for, and what refrigerant you are using. Just need to look up the pressure-temperature graph for the refrigerant your using and see what temperature makes it cross the pressure where the high pressure control cuts out at, and there's your answer.

[@RayRay-nb7tn]

You could look into getting K-Flex Insulation to put in between the vibration of piping it comes in .5 or 1inch thickness. Sheets or rolls. Plus incase the wires in Sealtight if worried about the wires cutting. Just IMO. Those motors always have problems braket cracks and breaks or rubber grommets wear out. As a pass Bryant dealer it was one of my biggest complaints. Always have to be aware of the weather. Great video on the importance of to be sure you have the correct parts. Thank you.

[@wiiyaasiniini5323]

I tell this story to non-HVAC people and they are like, meh. But one time a couple years ago I was on a roof for a service call during that polar vortex deal in Minnesota. All the rubber seals on my gauge set were frozen solid and leaking......LIQUID R404a, granted it evaporated pretty fast, but still it was COLD. So cold that that refrigeration rack equalized below the compressor cut-in during the night so it wouldn't turn on when called.

[@carlhelmick7711]

P.S. you would make an awesome teacher or an instructor. You really do a great job. 😀👍

[@mbainrot]

Make sure when you're doing lots of water you stay on top of your salts. I watched a cyclist at a riding competition have a massive melt down (looks at water, aaaand vomit, tries to move... aaaand vomits). They had apparently downed like 5-8 litres of water and didn't know about salts (the twins, sodium chloride (table salt) and potassium chloride) :\

[@44R0Ndin]

That's why if I knew I was going to be facing that much heat I'd make Gator-Aid from the powder packets, but I'd use 2x as much water as the packet tells you to because full strength gator-aid will make you vomit too. Half strength won't.

[@HighestRank]

Sure they knew. Cycling is yet another one of those sport-pissing contests. If you haven’t heard of water poisoning from sports medicine by gameday, then you’ve been licking the lead pipes at the gym for too long.

[@newliner26]

The only issue that I've seen with the desiccant breaking up into the system is green techs replacing a muffler (compressor discharge vapor) with a drier. I do prefer the Sporlan Catch-All driers but nothing will survive on the discharge line. Mistakes happen (great learning expense), glad they were at least thinking to replace the drier on a refrigeration repair. 👍

[@southernautodiy2643]

Shiiiit i could NOT work in 120 degrees at all, 90 degrees is my draw point as humid as it gets here 70 degrees can feel like 90, idk how you do it bro, these hvac videos are awesome! Keep it up and take care of yourself out there!

[@darrynf66]

What I hope is a simple question to answer...why would you spend so much time, money & effort on fixing not just an R22 unit but one so old & in such poor condition? In Oz we don't generally try & keep them going with R22 phase out but replace as a first choice.

[@HVACRVIDEOS]

Its the customers money and replacing equipment in California is stupid expensive....

[@chadhartsees]

Chris - you seem like you're very into using new tools and technology. What's your CRM like/do you have one? I often hear you say 'I think we were here' or 'My tech said this', have you thought of using a tool like a CRM to keep customer notes and to keep pictures of jobs stored so you can always know what the unit has going on inside it so you're sure you have the right valves/equipment or know what the situation is 'oh, looks like the leak was here, it's piped weird, I'll need additional fittings, etc'?

[@HVACRVIDEOS]

Yeah we have a crm and I can see previous calls and all that info. The one I use is called intuit field service management

[@heavydiesel]

Same as minisplits, most if not all only have strainers, no driers. The idea being it should be installed cleanly.
