"32% humidity is HIGH." I wish... 83.5% yesterday, temps in the 80s. That split condenser really surprised me with how gunky it was in the inside! It's not what one would expect, because the outer half looked recently-cleaned. I bet somebody hit it with a quick rinse and pushed all that crap into the inside, and then left it to dry.
aye, same here, the lowest I remember ever seeing the humidity (and i check frequently, multiple times a day, even in winter) was 43%. also 90% is incredibly common, and the highest ive ever seen was 108% when the temperature dropped rapidly one day, and walking outside made you feel like you were drowning.
@@hvac01453 In the vast majority of cases, when the air has particulates in it to make the water condense out of the air, yes, it is not a guarantee though, it is rare for the air to be clean enough for such a thing to occur.
Most likely only the service technicians will complain about bad schematics while trying to trouble shooting equipments, but service technicians have nothing to do with purchasing equipments, so the manufacture has no motivation to improve schematic design
This video was narrated beautifully as a training video for your guys, explanations along the way of not only what you are doing, but also why. Nicely done Chris! On a side note, the X terminal for the compressor lockout board, is that terminal just for troubleshooting? Or are there systems out there that bring that terminal back to a thermostat or building control system for alarms or other purposes? (And finally, that was a nasty split)
This video it seemed like you were training a new tech or perhaps an apprentice. It was absolutely AWESOME to hear you explain some of the stuff in simpler terms. I know most of your audience is HVAC techs, but some of us are just regular guys interested in learning. Your regular videos are great, but every once in a while a "training " video is very welcome!

Great video, I learnt a lot! But my inner engineer is screaming though. Dust and electronics usually don't combine well. Those connectors and exposed circuit boards are a prime example of a system designed to fail.
Chris: “We have high humidity right now and I bet it’s 32%, 35%.” FL: “That’s cute. Hold my beer.” Current humidity level outside is 90%+ dealing with outer rain bands of a Tropical Depression. I wish it we had a 35% humidity level.
Let me guess, the company that produces R22 has their patent about to expire and just happens to have a new safer for the environment refrigerant. So just like R12 they lobbied government to replace R12 with their new "safer for the environment" refrigerant R-134a.
That was a pro find splitting that condenser. I bet most techs wouldnt split that condenser and just washed the outside of the condenser coil. Great video. Try to burn yourself out in this heatwave
I appreciate the details my service manager and senior techs drill in to us. We always split condenser coils for cleaning because it gets matted between them. We have been earning new service contracts lately because of our thoroughness and detail when asked for second opinions on repair quotes.
106°F all week in So.Cal except for Friday we had some offshore clouds come in making 100°F with 32% humidity, that was a nice day. On a roof in Arizona, and So. Cal the radiant heat is 5°-10° degrees hotter than the actual temp. Chris and guy's like myself deal with temps upwards of 114°-120°F +. My respect goes to the Las Vegas, and Phoenix guys🔥.
@@TheMaster5150 What sucks when it's 115 plus for a solid week.. when it's over 15% humidity is like working in an oven.. Been in Vegas doing HVAC 20 years and it doesn't get any easier...

Great video, and Happy Father's Day!! I worry about you sometimes, the way you'll cancel a family outing, or work til 2 am saturday night changing compressors. Point being .... it actually made me smile as I'm sitting here with my 3 kids to hear you say you weren't going to spend your weekend putting some kind of band aid on their AC just because they would like their bathroom cooler. You're entitled to some sanity, and I have to stop and tell myself that sometimes too. We all do. hope you enjoy your day. The sun will go down and it will come up again and whatever restaurant that is will have made more money than they did last Father's day and they'll live.
you guys would laugh at my 1977 central air unit i have maintained it since 77 it is 100 today and its cooling my 3500 square foot house just fine it struggles if you put thermometer below 77 though its had a run capicator replaced and fan motor other than that nothing.when i watch you guys work on these new ones they look so big and complicated.you guys understand electricity for sure!
Burnt to open,see it all the time! Slow burns are the worst as far as contamination is concerned! I've done simple opens that weren't too bad and I've done some where I condemned to unit,due to the black sludge oozing out!
25:57 are u sure filter are clogged up will cause this over heating issues? already cleaned con...out havent check filter to see if it clogged could lead overheating
Does taking in outside air ever have a downside, like if a big diesel truck drives by the building and the system sucks in some of the petroleum smell?
The humidity here is 82 percent. No it's not raining or cloudy. It's not too hot yet. I can stand hot temperature in low humidity. But 90 degrees at 82 percent humidity is horrible. I consider anything below 45 percent as low. I also want to add, all of our distributors are completely out of R22 except one. I'm not getting anymore. I'm experimenting with MO-99 and 407c
one sensor read 39f one nothing, yet both read 10k ohms on the deck? First thing I would have done is swap them out to see if the misreadings follow . the new ones were 15k which isn't miles away (and depends if the van was as hot as outside) I think I would have let the old and new equalise temp on the deck and remeasured. I'm suspecting bad connections but you know these units better than me for sure. Great video as usual.
I absolutely hate those double row condensers. The Lennox HS 25 condensing units are designed this way. So many are not aware of this, and they see the outside is clean, so they don't think its dirty. You have to remove the fan top, and get in between the 2 coils as well.
32% humidity. Im in Kentucky. Its 5:30 AM. Humidty is 83%. I miss living in southern california, humidity is hell. Here's what high humidity does. we had a broken AC. During the day the temperature inside, according to the thermostat, got to 83 degrees. So after an entire night, know what the temperature inside was? 81 degrees.
You think 32% is high? try living in Florida during summer. Temps don't get quite as high (80s 90s, sometimes we'll break 100, but it's rare), but the humidity at 60-80+% makes it BRUTAL. Also, are you training a new tech? It seems you were showing someone new to the trade how to do it.
everytime you say three phase high voltage 208V i giggle. simply because the voltage in my power points is higher at 240v, three phase here is like 415V (australia) edit. also feels like your in teacher mode, teaching a new fella the ropes
Would a really small pressure washer help with split row condensers? I'm aware you can't use super high pressure, i believe there are even battery powered units :) Have a nice day!
I always thought those three dots on the compressor were a soft plug. But I was told that those dots of what it looks like solder was just where the windings are suspended from via a weld. Maybe I was right then?
First unit, why is the mixed air temp sensor after the evaporator? Mixed air should be blend of OA and RA without treated air. Yes I understand it is a small package unit and there is no “good place”. Per the logic it still works.
On choked condensers. Onboard ships we blow with air first then wash because some of the finer particulates were turning into a hard cement-like-crete when wetted and then dried. Good for when you hae easy airline access. I don't work on the refrigerant cycle part of the plant yet but will eventually.

Question: What is the reason the economizer controller shut the AC down when detecting sensor failure? Why they can not just keep the AC running, so the overall system still works at least somehow? Why it is preferable to leave the customer stranded than just consume a bit more electricity till fixed?

Wish most companies would use teenagers as a laborer. We need to get the younger generation into the trades. The information you are showing us is great information!
Awesome videos really like it .about the the unit running in high head pressure and and little bit high suction pressure. And every thing seem to be fine Do a pump Down test to see if the compressor is not the problem. The compressor must hold the charger in the condenser and if Dose hold its Definitely a caked condenser wich actually was until clean up jejeje. And if its still little high head pressure it's over charged unit. It's a amazing find of the cake condenser jejeje.
i agree. i watch a heavy tow operator and ive learnt a few things from that and i started guessing which way hes going to use from what ive seen previously
have you guys seen steve lamores? channel he hates the old units bitches and moans ..now im 59 see i would be the opposite if i was a hvac guy i would be like damn finally a old unit to work on a real classic here!.kinda like old bodymen that love old cars.lets save this old dude shes worked hard....smiles
You ever tried some of those airtox work shoes with the plastic toes? 250g-something compared to whatever else you're using? I've been using old steel toes for my entire careerer, so I gave the airtox try and damn they are so much lighter and much more comfortable to walk in all day.
when you guys are struggling in the heat fixing ac units im working in bodyshop with no air throwing chains on frame machine fixing truck frames and im the only paintless dent tech in shop so i have to do them to and paint and do big dent stuff but i respect you guys alot wish i woulda been hvac im qualified and trained in cars but not the new ones with the y refrigerant
Damn from seeing someone else hood meter leads it’s different lol good apprentice 👍 you just know if the person has experience in troubleshooting by the way someone holds the meter leads. Good video Chris happy Father’s Day just got out of work eating mickeyds and now seeing this. 👌🥴
We see a ton of cottonwood tree fiber in the air around here this year. Some years are worse than others. I had to remove what looked like a wool mat pad between the radiator sections in a truck a number of years ago. It looked like a rolling wave across the street as you drove that year.
Excellent knowledge transfer experience!!!! Broke it down, step by step in an easy to understand way! I'm sharing this one with our new techs.... Thanks Chris!!!!!
Thanks for explaining the entire process on that first unit, and also thanks for explaining where to take temp readings on the suction and liquid lines. Your videos are 1st class.
I noticed your tech was in blue. Do you require your tech's to wear blue? Also Like it when I see your tech's working and performing tests. You also learn by doing.
On split coil condensers I've had a fair amount of luck getting the sandwich crap out by simply deluge flushing from above and not pulling them apart much. On residential units people expect to last 20 years you don't want to do much flexing. Used a gallon pitcher that has that shield over-top the pour like a watering can, splooch muck gone.
Hi, I am from Australia and was in the industry many years ago and still find it interesting as to follow you. Do you have regulations for exhaust and fresh air intake separations and design criteria for exhaust fan installation particularly in relationship to being in roof wells. I also found exhaust contaminated used get into aircon unit condenser coils due to weather conditions.
This was a really good troubleshooting breakdown from start to finish. I’ve been in the field for 10 years and I picked up some really useful information from this one video. Keep up the great content. Subscribed!
Is that an OSHA approved brick you're standing on? I prefer the OSHA approved 5 Gallon bucket step stool myself 😜
My old man, being a bricklayer, always used at least two bricks stacked on one side and a bucket on the other, with a plank between them. Redundant safety-every time.

Even tho the subject is boring af its interesting to watch professional at work explaining everything.
i agree. i watch a heavy tow operator and ive learnt a few things from that and i started guessing which way hes going to use from what ive seen previously
hmm more work..hey hey dont knock it. tiz all cash coming in..whats your trainees name ? coz you never say "we" when you both finish a job..
have you guys seen steve lamores? channel he hates the old units bitches and moans ..now im 59 see i would be the opposite if i was a hvac guy i would be like damn finally a old unit to work on a real classic here!.kinda like old bodymen that love old cars.lets save this old dude shes worked hard....smiles
You ever tried some of those airtox work shoes with the plastic toes? 250g-something compared to whatever else you're using? I've been using old steel toes for my entire careerer, so I gave the airtox try and damn they are so much lighter and much more comfortable to walk in all day.
What an odd coincidence with that temperature sensor. The bad reading was pretty close to actual temp in Celsius.
Wow one of your best videos ever, Carrier troubleshooting 101 👍
when you guys are struggling in the heat fixing ac units im working in bodyshop with no air throwing chains on frame machine fixing truck frames and im the only paintless dent tech in shop so i have to do them to and paint and do big dent stuff but i respect you guys alot wish i woulda been hvac im qualified and trained in cars but not the new ones with the y refrigerant
Damn from seeing someone else hood meter leads it’s different lol good apprentice 👍 you just know if the person has experience in troubleshooting by the way someone holds the meter leads. Good video Chris happy Father’s Day just got out of work eating mickeyds and now seeing this. 👌🥴
We see a ton of cottonwood tree fiber in the air around here this year. Some years are worse than others. I had to remove what looked like a wool mat pad between the radiator sections in a truck a number of years ago. It looked like a rolling wave across the street as you drove that year.
What are your thoughts on Blue Box? Is it a breakthrough innovation or overhyped?
I was today years old before I finally came to understand ECONOMIZERS! I'm now off to sign up for this stuff on Patreon. Bully Chris!
Thanks so much bud!!
Excellent video, such great information, thank you.
on unit #2 you let out some refrigerant and smelled it. Isn't that bad for the environment?
I usually wash them from the inside outwardYeah clean that baby if that coil was that dirty then they all need to be cleaned
r32 is the future, in the eu r22 hasnt been sold for years and the only way to get more for one old system is to recover it from another
“Coil porn.” 😂
Please stop the apostrophe abuse... ;)
Excellent knowledge transfer experience!!!! Broke it down, step by step in an easy to understand way! I'm sharing this one with our new techs.... Thanks Chris!!!!!
Great video. I used to be in the overhead crane world and screamed for keeping certain parts on the service fleet. Saves so much time and headaches.
I couldnt be first sadly. and yes happy fathers day cause you need it
Thanks for explaining the entire process on that first unit, and also thanks for explaining where to take temp readings on the suction and liquid lines. Your videos are 1st class.
As usual, nice work Chris. Again, love the satisfying shots of cleaning the dirty coils.
Happy Father’s Day brother
Before watching I’m going to guess logic board is set wrong or bad
New refrigerant is out there but selection VERY limited
This video makes me want to work in the HVAC industry.
I am only 18 years old and I fixed my own air conditioner.
Good job sir,thank you for the class I appreciate it
I just learned 3 things. #1 Economizer temp sensors #2 Split the coils (never took it seriously) #3 Voltage between x and c
Having watched a few of your videos, the economiser often seems to be a point of failure on package units.
I will discuss this on my Livestream this evening 6/21/21 @ 5:PM (pacifc) come over and check it out ruclips.net/video/4iij_8bvstc/видео.html
I noticed your tech was in blue. Do you require your tech's to wear blue? Also Like it when I see your tech's working and performing tests. You also learn by doing.
On split coil condensers I've had a fair amount of luck getting the sandwich crap out by simply deluge flushing from above and not pulling them apart much. On residential units people expect to last 20 years you don't want to do much flexing. Used a gallon pitcher that has that shield over-top the pour like a watering can, splooch muck gone.
All refrigerant has skyrocketed. In my area 410A is up 200% in the last few weeks. Gonna be a interesting summer I suspect, hope I'm wrong though
Hi, I am from Australia and was in the industry many years ago and still find it interesting as to follow you. Do you have regulations for exhaust and fresh air intake separations and design criteria for exhaust fan installation particularly in relationship to being in roof wells. I also found exhaust contaminated used get into aircon unit condenser coils due to weather conditions.
This was a really good troubleshooting breakdown from start to finish. I’ve been in the field for 10 years and I picked up some really useful information from this one video. Keep up the great content. Subscribed!
can you use material on 23:04 to make ugg boots instead of washing it off?)
Thanks Chris. Awesome step by step diagnostics.
