You made me think about my very first TXV replacement job early in my career - A co-worker (Tom) condemned it based on low suction pressure (clue), and I got sent out to do the job. After finishing the work, I still see low suction pressure. Didn't take long to discover the clogged return grille in the store... That boys and girls, is how I learned not to trust other people's work, and to check all return grilles. That's also how Tom earned a kick in the ass the next morning. Those were good times.
@@Stuart68505 That's kind of the point/lesson learned. A quick cleaning of the grille and I was good to go, but had the original tech noticed it before condemning the TXV or if I had done my own diagnosis before swapping the part, and we could have saved ourselves a whole day's worth of work.
I like the way you admit to your past mistakes so that others can learn from them. I'm a great believer that someone who doesn't make any mistakes doesn't learn.
So that wasn't just me? Thought I was having some kind of acid flashback. And that really freaked me out because I've never done drugs. Or did I and I just don't remember because of the drugs. Now I'm really freaked out.
Starting HVAC school at the end of this month, your videos are more then just some guy rambling, more like a guy that is a good teacher and leader! You go above and beyond in my eyes buddy keep up the good work.
Thanks so much bud!! I will be going live on TH-cam this LaborDay evening 9/7/20 @ 5:PM (pacific) to discuss my most recent uploads and answer questions from email’s , the TH-cam chat and the live chat. Come on over and check it out th-cam.com/video/vLwC4yR3ppc/w-d-xo.html
You know that it's going to be a fun service call when the customer tells you "The A/C unit sounds like a goddamn earthquake." Noise calls are wonderful
I'm an installation tech for resident and roof top units watching and listen to you ramble I learn more and help me to be more attentive thanks for your time
So I am an IT professional by trade now and have been for ~6 years and love what I do, it's been my dream job since I was like 8, I've had absolutely no experience really with repair of anything HVAC/Refrigeration related however I find these videos incredibly satisfying to watch. I have however been an appliance repair tech in the past, Commercial Toasters, Microwaves, Televisions/displays, Projectors, Washers/Dryers/Dishwashers. TLDR; Keep putting out the awesome content, I have a real appreciation for people who are passionate about what they do & enjoy what they do, may not always enjoy the situations they're put in but you're a hell of a tech and you do a fantastic job of explaining everything.
You are a real repairman and a real human being. You even tell the things you hvae previously done wrong and that is a fine personality. I think not many repairers are able to tell anyone that they have previously done something wrong.
Good video ! Like # 426. For the New techs out there - Regarding the Vibration. When they vibrate violently the wheels have most likely Lost a Weight & Cleaning Will NOT SOLVE the vibration issue. U will probably make it worse. Cleaning is Risky because if u Loose a Weight You are screwed. Best to Replace as Chris did here. Also Allways have on Truck stock extra key stock & An assortment of Allen set screws. You can buy Raw Key way material where you buy Your Bearings. King Bearing is a Good place to buy that stuff. Pillow block bearings , Regular Bearings & shafts. Good vid.
Turning vein cleanliness was an education within it's self, as well as, cleaning grills while down was an often over looked procedure which won't be since I watch this video. As usual I was glued the entire time. Thank you.
That blower looks like those videos where people take an old washing machine connect the motor direct upto 240v then throw a brick in it. Add some Harlem shake music for good measure.
I’m fresh out of Hvac school and Mann I’ve learned soo much just watch your videos. Contemplating why I even got a two year degree in HVAC. Love the vids my guy keep em coming
Every time I watch a video I wish you had been the one who taught me everything I needed to know about HVACR. Very impressed with how thorough and educated you are, good up the good work and videos 👍🏻
That was really good advice about torquing down / scoring the key with the set screw. Sometimes the key doesn't always sit perfectly straight in the groove. This ensures it does.
Very interesting, here in South Africa the cleanup and repair would've been cheaper than the replacement. Great video! Really enjoying your stuff. It's fun to see how HVAC techs do their jobs in different countries.
I suspect that would be the case a few dozen miles to the South of this site, once you cross the border into Mexico... labor rates are vastly different.
He never said it was cheaper. It’s about value. Problem with your mindset is they pay you to do nothing. If they really want to save money they would clean it themselves. Imagine paying someone to do a timing belt in a car and not the water pump?? Which locks up shreds the new belt and bricks the car anyway.
It's best to use actual earplugs or earmuffs instead of headphones since they're built and certified to keep your ears safe. I've always liked the little disposable expanding earplugs since they don't make my ears sweaty and they don't hurt the insides of my ears. Anything is better than nothing, though.
Both plugs and muffs should be used especially for angle grinder cuts on stuff that resonates like sheet metal... When I saw the author suggesting to use earbuds (the ones used to listen to music) I couldn't believe it!
Please spend some money on properly rated hearing protection to go with that angle grinder. Audio playing ear buds can cut the noise down a good deal, but they don't always fit perfectly or block all the frequencies well enough. It's also a small price to pay to avoid a very legitimate OSHA compliant of not having necessary PPE for employees.
Good video! Knowledge is Power... My last new office I worked in had some hidden filters that weren't changed in the 6 years I worked in that building. At some point someone queried the supply & the filters were found - paper, crumbling to touch! The office prior to that was the Centerpoint building in Sydney, Australia. After 30 years of operation & probably poor maintenance, we had to get the duct work cleaned, as dust was sputtering out onto staff... That same building had two small water cooler towers on the roof - to service the Computer Server room. One day, someone on our floor came to my area incapable of speaking what they'd just seen; one of the stacks from a tower - the guy wires holding the stack in place snapped, with the fibreglass stack falling down in between the our building & the next one. A few yards in the other direction & the stack would have fallen onto the street below. Sydney is similar to New York, so it wouldn't have been a good outcome...
Yeah, I replaced a cap on my Father in laws Central AC and brought it back to life gaining a Central AC Hero status, and I replaced the evap fan motor in my grandmothers Central AC gaining quite a few raised eyebrows, These things always seem to happen when its above 98F and it will be weeks before a tech can address (I did convince my grandmother to have a tech do preventive maint on an annual basis, and not by me either) I had to go back and- check the amperage since I only learned how to do that recently, thanks to your videos..... I'm not a tech, I'm a Jack of All Trades, Wyle E. Coyote 'super genius, I don't have an industrial sized puller and I'm not certified but I never release refridgerants into the atmosphere. (I'd love to get one of those refridgerant remover systems. So Central Air is only a Jack-of-All for me but I absolutely really enjoy watching these videos, they are magnetically interesting, don't ask me why. I learn tons of stuff everytime that I'll never put to any use unless its some end of Earth emergency or cross-training-info-seep into some other profession that I ave absolutely no business sticking my nose into (NOT, I'm a throwback from the 50s, a baby boomer who thinks America has lost all shame with the throw away culture thing.....). Really, I'm 56 and never had any sort of disaster in my Jack of All trades and watching these videos only helps me be safer, since I'll never stop doing things that I'm not qualified to do (I do know when to call for real help though. I'm not too stuborn or proud and I've saved enough $$ doing it myself at times that I can afford to call a pro in when its over my head.... Yeah, your HVAC videos absolutely rock!
when you do those locking collars, your supposed to whack them on an angle in the direction of rotation with a flat tip screw driver in the hole that has no set screw in it. To loosen it, you whack it in the opposite direction after you release the set screw.
That's the ultimate price of not doing maintenance (including regular cleaning): you pay for a complete rebuild. Possibly suffer a breakdown before that. Solid logic quoting the rebuild right away! 👍🏻 PS PPE ftw, no one should have tinnitus because of work. Have both tinnitus and hearing loss because young and stupid. 🤬
This your older smarter self talking to from the future, always keep -33db earplugs & use them often in addition to the muffs. I figure every hour with the plugs in equals a couple more months of better hearing in your retirement years.
Anyways, like I was saying, you can use anything as a hammer. Channel locks, couplings, conduit, back side of a drill, screwdriver handle, boots, any and all wrenches, an apprentice...
When I ws a kid, I remember a neighbor having a Lau window fan, but I haven't seen that brand name in nearly sixty years. It's nice to know they're still in business, and still manufacturing fans in the USA!
The video's are fantastic. I see something different every video and i still have no idea how anything works :) But its fun watching you fix stuff! And its crazy how much you know about all these HVAC systems. I looked into it and it must take years or decades to get to the point where you know most of it!
If possible I would use a good penetrating oil and a brass drift and hammer to remove the shaft otherwise I would prefer a hand held bandsaw to a grinder because of the noise and Sparks flying back at you! You did a great job there is no easy way to do this kind of work! Thanks for another awesome video!
HVAC engineer here, i tend to show radiused elbows rather than mitered ductwork with turning vanes because they are cheaper. i only used miters if there is a space constraint that will not allow radiused elbows. this makes me really nervous about using mitered in a kitchen setting, but it's pretty rare that I design a kitchen without plenty of space above the drop ceiling.
That unit is just beat up as all get go and it goes to show why you should always do maintenance. Keep up the hard work and thanks for the content stay safe and take care
I've done two blower assemblies for Carrier 48TF series the 15 and 30 ton units. It's the biggest pain in the ass. You have to lift the whole assembly out of the top of the RTU and then you can take it apart. It's nearly impossible to do without having to sit inside of the RTU and lean against the evap just to screw everything back in. The reason we had to make the replacement is because those locking collar pillow block bearings failed. One RTU had both blower wheels explode and throw all of the blades ontop of the heat exchanger.
Great video and now I know how change those double wheel blower motors. By the way I just spend about $2300 worth of tools and used your code Bigpicture. Thanks for the discount
Woooow man. That was a lot of work and well done. Thank you very much for this video. Full of tips and notes for you to keep in mind in case one of those jobs comes in.
Great info Chris never knew that the suction power at the blower would be a restriction. Great work as always stay cool in this crazy Inland Empire heat.
One thing I've learned from these videos is when Bruce Willis climbed out of that HVAC duct he should have been filthy head to toe. "Yippie Ki Yo I need a shower!"
People usually have to remind me to take earplugs out. I just like the peace and quiet. The foam plugs are just like turning the volume down on the background noise for me. I feel like I can focus on my work better.
cosmoline works really good for shaft protection against rust, theres no grease in it so nothing gets stuck to it and wipes off with a rag and some cleaner
Working in Las Vegas, Dirt is our worst enemy. I focus on cleaning everything I can because it's amazing how dirt affects our equipment.. messes up balance and ruins our heat transfer..
Thanks so much bud, if you know what your buying if you dont mind send me an email and I can generate links that will help me out a bit more.... hvacrvideos@gmail.com
I have friends that refuse to do preventative maintenance on their homes, vehicles and shop tools, I can’t stand it. I often point out what could be replaced to prevent a failure, but just get told I’m *following the instruction manuals too closely*. Yes, some manufacturers abuse the system by getting you to change fluids , expendables and other parts far more often than necessary, but many don’t , they do it to keep you , your tool , and others safe.
@@awesomestuff9715 The bandsaw isn't really loud enough to need hearing protection, about the same as a cordless impact or maybe quieter. Cutting certain materials in a confined space might be louder. The main danger with the bandsaw is possibly getting it stuck and breaking a wrist. Audio feedback can help to avoid that, and roof is usually safer in general without earmuffs but I suppose it depends on the particular saw and person and situation
Reminds me of the time they told me to go up on the roof where I work and look at one of the exhaust fans. Because it sounded like an earthquake. I opened it up and the pulley (shaft and all) is just bouncing around like crazy. I go downstairs, the first thing they ask me is, 'Is the belt loose? Does it need to be changed?' (note: I don't work on these) "??? I don't know, it's shaking." "well, you can't just leave it off, turn it back on.' 'I left it off because the whole fan is bouncing around.' 'Turn it on.' And for the rest of the day the customers got treated to a neverending earthquake...And they acted like I did something wrong.
I had an install last year we did all metal ductwork on a 35 ton rooftop the duct dropped down 8 or 10 feet then a square 90 right out of the unit and it was big ductwork but you should have seen how much it vibrated that section of duct
For hearing protector my preference is the Peltor Optime III (H540A) by 3M. But for your work it might be sufficient with the Optime II (H520F-409-GQ) that are available in a foldable variant so that they can be safely stashed. Sweaty ears is a small price to pay for a good protection. Maybe I have noted this before, but I prefer black zip-ties since they seem to not degrade as fast, especially in sunlight.

I had a chance to see by myself AC units in one huge hotel in the Charleston. Access to the filters are located in the middle of nowhere. There is no any human access to them. And because of it nobody never changing them and system is running non-stop. Also, I never saw if someone changed any filters in the room units. And the owners just saving money and getting as much profit as possible. Hotel was like 400-500$ per night.
Turning vanes are rare in such a system - they just aren't all that cost effective for small installations. The do help reduce the loss factor (k value) for tight square elbows, which ties into fan dP and thus power consumption, but at the cost of obstructing the airflow. I'm not sure what the installers did with that ducting, but it is indeed more than likely that there is at least one more such elbow between the intake and the blower.
I found out that if you don’t loosen up both set screws on variable pulley, it’ll be oblong enough from the adjustment set screw where you’ll fight getting it off. Next time try loosening both up and it should come off easier.
At least you kept the original Reliance motor. I would think a Mars or Supco replacement probably wouldn't be as reliable in the long run. Don't have a gas axe?
Did you put note on outer blower area to tell them about zerk on inner bearing, or like I did on some semi,trucks,added a,hose,with. A zerk on end because were zerk is,placed,hard,to,get at or always, covered in mud and dirt
I like to leave the pulley loose on the shaft, not the sheave (that's on the motor, of course LOL) put the belt on and spin it, the belt pretty much aligns itself.
yo not to throw shade but your head is really round like egg round

You made me think about my very first TXV replacement job early in my career - A co-worker (Tom) condemned it based on low suction pressure (clue), and I got sent out to do the job. After finishing the work, I still see low suction pressure. Didn't take long to discover the clogged return grille in the store...
That boys and girls, is how I learned not to trust other people's work, and to check all return grilles. That's also how Tom earned a kick in the ass the next morning. Those were good times.
Why not clean it?
@@Stuart68505 That's kind of the point/lesson learned. A quick cleaning of the grille and I was good to go, but had the original tech noticed it before condemning the TXV or if I had done my own diagnosis before swapping the part, and we could have saved ourselves a whole day's worth of work.
I like the way you admit to your past mistakes so that others can learn from them. I'm a great believer that someone who doesn't make any mistakes doesn't learn.

cosmoline works really good for shaft protection against rust, theres no grease in it so nothing gets stuck to it and wipes off with a rag and some cleaner
Yes but every tech should have a can of anti-cease in there tool bag and it probably works nearly as well.
Chris: NOOO!! YOU CAN’T JUST NOT DO PM PROPERLY!!!
Customer: haha blower fan go squeak squeak boom
lol

Been watching your video's for a while from the UK :-) I work in IT but find them very interesting and informative. Cheers!
Thanks so much bud!!
Working in Las Vegas, Dirt is our worst enemy. I focus on cleaning everything I can because it's amazing how dirt affects our equipment.. messes up balance and ruins our heat transfer..
Chris I bought some stuff from truetech and I used the discount. Going to buy about $2000 next week.thank you
Thanks so much bud, if you know what your buying if you dont mind send me an email and I can generate links that will help me out a bit more.... hvacrvideos@gmail.com
I have friends that refuse to do preventative maintenance on their homes, vehicles and shop tools, I can’t stand it.
I often point out what could be replaced to prevent a failure, but just get told I’m *following the instruction manuals too closely*.
Yes, some manufacturers abuse the system by getting you to change fluids , expendables and other parts far more often than necessary, but many don’t , they do it to keep you , your tool , and others safe.
For cutting those shafts without a dead wheel you can try a cordless m12 bandsaw. It will be much quieter.
i mean, its still better to wear hearing protection either way because you dont want to get hearing loss
@@awesomestuff9715 The bandsaw isn't really loud enough to need hearing protection, about the same as a cordless impact or maybe quieter. Cutting certain materials in a confined space might be louder. The main danger with the bandsaw is possibly getting it stuck and breaking a wrist. Audio feedback can help to avoid that, and roof is usually safer in general without earmuffs but I suppose it depends on the particular saw and person and situation
Or a recip saw with a good metal blade, cuts through it like butter with minimal noise.
I got to admit on the bearing as i thought exactly the same thing you did in regards to the tightening the concentric lock!!
Reminds me of the time they told me to go up on the roof where I work and look at one of the exhaust fans. Because it sounded like an earthquake. I opened it up and the pulley (shaft and all) is just bouncing around like crazy. I go downstairs, the first thing they ask me is, 'Is the belt loose? Does it need to be changed?' (note: I don't work on these)
"??? I don't know, it's shaking."
"well, you can't just leave it off, turn it back on.' 'I left it off because the whole fan is bouncing around.' 'Turn it on.'
And for the rest of the day the customers got treated to a neverending earthquake...And they acted like I did something wrong.
thanks for the video educational as always. 11:35 everything is a hammer
Listening to you ramble sure beats watching the crap on TV 🍻
I never had to do a complete fan assembly reassembly, i take my hat off to you,,,..
You left two cuts about the locking nut m8 8:48

Déjà vu
@@Andrew_Sparrow The Matrix is glitching.
He just wants everyone to know that he made a mistake and is fixing it now.
@@ZNotFound Then had to fix it again, cause he did the same thing immediately again. :P
These fasteners are SAE, so there is no M8. What "cuts" are you talking about?
I'm sure someone already pointed it out, you added the clip about the locking collar twice. Otherwise, great video Chris.
Great vid. All the best from Liverpool UK
side cutters as a hammer. absolutely works.
Are you going to check to blower motor amp draw again after cleaning out the duct work? I'm sure it will be moving more air and using more amps.
I had an install last year we did all metal ductwork on a 35 ton rooftop the duct dropped down 8 or 10 feet then a square 90 right out of the unit and it was big ductwork but you should have seen how much it vibrated that section of duct
Isee you've been to Harbor Freight and purchased some roll arounds. I have a few myself.
Wish you could upload how you fit the blades. And the shaft plus the bearings
That blower sounds like a Diesel engine lol 🤣
Yah but only a Cat not a 2 stroke Detroit.
For hearing protector my preference is the Peltor Optime III (H540A) by 3M. But for your work it might be sufficient with the Optime II (H520F-409-GQ) that are available in a foldable variant so that they can be safely stashed. Sweaty ears is a small price to pay for a good protection.
Maybe I have noted this before, but I prefer black zip-ties since they seem to not degrade as fast, especially in sunlight.
Always another great videos.
I've found using a saw zaw with demo metal blades work very well on those shafts.
Take care of yourself man. You look tired. It is been a long summer. Thank you for taking the time to do this very entertaining and educational videos. I am buying some tools using your promo code from True Tech tools.
Thanks so much if you know ahead of time let me know and I can generate affiliate links that can help me too, I will discuss this on my Livestream this Labor Day evening 9/7/20 @ 5:PM (pacific) on TH-cam come check it out and no worries if you cant make it live as it will post as a normal video afterwards. th-cam.com/video/vLwC4yR3ppc/w-d-xo.html
I was pleased to see you using anti-seize. IDK if you use it all the time, but you almost never mention it. I put that sh*t on EVERYTHING. The next guy will thank you.
OMG look at that belt
Man you always kill it good shit
Awesome video
Dude amazing work, loved your video!
I will be going live on TH-cam this LaborDay evening 9/7/20 @ 5:PM (pacific) to discuss my most recent uploads and answer questions from email’s , the TH-cam chat and the live chat. Come on over and check it out th-cam.com/video/vLwC4yR3ppc/w-d-xo.html
I have no idea what I'm doing here but I enjoy watch those videos 😂
Love your videos, really informative
Every time you tested the blower that could hear it start up and it had a really cool startup sound
Great job and video
I had a chance to see by myself AC units in one huge hotel in the Charleston. Access to the filters are located in the middle of nowhere. There is no any human access to them. And because of it nobody never changing them and system is running non-stop. Also, I never saw if someone changed any filters in the room units. And the owners just saving money and getting as much profit as possible. Hotel was like 400-500$ per night.
To quote another TH-cam AC guy, "Good enough for this neighborhood", "you ain't got no Taj Mahal here right". Great video, keep them coming!
good ol' Steve
I would be interested in seeing current draw on the indoor blower motor before/after cleaning that return air grill.
Turning vanes are rare in such a system - they just aren't all that cost effective for small installations.
The do help reduce the loss factor (k value) for tight square elbows, which ties into fan dP and thus power consumption, but at the cost of obstructing the airflow.
I'm not sure what the installers did with that ducting, but it is indeed more than likely that there is at least one more such elbow between the intake and the blower.
I found out that if you don’t loosen up both set screws on variable pulley, it’ll be oblong enough from the adjustment set screw where you’ll fight getting it off. Next time try loosening both up and it should come off easier.
13:10 that is brilliant, thank you!
At least you kept the original Reliance motor. I would think a Mars or Supco replacement probably wouldn't be as reliable in the long run.
Don't have a gas axe?
Love these videos, got so excited when I got the notif
Did you put note on outer blower area to tell them about zerk on inner bearing, or like I did on some semi,trucks,added a,hose,with. A zerk on end because were zerk is,placed,hard,to,get at or always, covered in mud and dirt
I like to leave the pulley loose on the shaft, not the sheave (that's on the motor, of course LOL) put the belt on and spin it, the belt pretty much aligns itself.
I've seen plenty of those turning vents mainly restaurants
