Good job Big John. I just cleaned out our outside condenser coil. It was covered with vines. I cleared out the vines, pulled the power, lifted the fan motor housing, and sprayed out the coil inside and out. I need to get some detergent. Then went down in the basement and changed out the filter. There was also an access panel to the indoor condenser coil, which was matted with cat hair in only one year. So I washed the indoor coil too. Last night it was 80 degrees inside the house. I had to shut off the a/c until this morning when I could get a look at the problem. I thought the condensing unit had gone back, but this morning I turned the a/c on, everything was running fine, even the squirrel cage. All the system needed was a good cleaning. Now I'm sitting here in a nice cool house while outside it's 90 degrees with high humanity.
Take care John and thanks for posting these videos. Next year we're looking into getting another Goodman. This one has lasted 25yrs and still runs like a champ. We just figure it's time for an upgrade. I wanted to order one online, the entire hvac system with outside condensing unit and gas blower delivered to the front door for about $1500 then find a contractor to do the install. Trying to save a few bucks on a fixed income and budget. What do you think?
Tune in tomorrow for another episode of The Angry Tech.
Hi, John Israel this is Jermey McGuire. I, had a 5 ton Lennox XC16 air conditioner that cooled upstairs. Back in July 2022 the high pressure switch tripped, we had to get a tech out to reset the high pressure switch. And cleaned the coils and last July my blower Moyer failed.”
Had to get the blower motor replaced, unfortunately I had to replace both my downstairs and upstairs air conditioners.”
Back on Wednesday 4/1024
Lennox is so expensive!!
Just to get a part replaced, to bad Lennox won’t let you use universal parts like Goodman.
And Goodman keeps parts in stick, then having to call the manufacturer to get the factory part you need.”
I don’t recommend Lennox to anyone! Lennox is a big pile of 💩💩 the 5 ton Lennox air conditioner I had was 15 years old it was time for her to hit the road!! 🤣🤣🤣 good job cleaning the coil John!! 👏🏼👏🏼👏🏼👏🏼
This is true. I asked an experienced HVAC technician about the best way to clean the coils. He said clean them the best way you can. It doesn't matter the direction, as long as you keep them clean and jet the water at a downward angle. Most home owners will not remove the fan assembly or take the panels off. So just rinse the coils with a water hose and a low pressure nozzle is better than nothing.
Ive clean coils this way since 1984 and have never had a problem. In fact that's how they taught us to clean coils in school and now all of a sudden it's a problem. Overtime dirt and dust gets pulled in between the coils regardless and it comes out one way or the other regardless. Just keep doing what you do dude.
It's because of the stacked or double coils. It pushes it in between the two coils the you have to split the coils.
THEY TAUGHT YOU THAT IN SCHOOL? THEY DIDN'T TEACH US THAT IN HIGHSCHOOL OR AS A KID WTF
@Jacket of the 80's most likely technical school for HVAC
@@wokejoke2675 - Did you catch the part where I said "never had an issue".. I don't do micro-channel coils like that, but older coils I do. If water is passing through the coil, so is the dirt... it's not too difficulty of a theory.
@@dannysmith713 - Those types of residential units dont have a dual coil.. it's single stage..
I honestly love doing the coil cleaning on my checkups, it's one of the most visually rewarding parts of the tuneup if they're really dirty like this. It's so easy but it's making such a big difference for efficiency and heat-exchange.
On something like that I'd do it the same way but also like to hit it from the inside out to make certain I have a clear stream of water. I use a 3/8" diameter by 4' rigid copper spray nozzle I built to spray the coil from the inside without having to disassemble the whole unit. Basically like the needle jet. Good to see someone else cares about the quality of their work.👍
Probably takes you 2 hours as well
@@murkyturkey5238 ok?
@@HVACRSurvival washing coils is a conspiracy
Not a big issue with the older 10 SEER units that had flat fins and reasonably spaced around 14 fins per inch. But the newer high efficiency coils have fins that are much tighter and they are not flat. They have little scoops stamped into them with the opening facing the outside to make the air more turbulent resulting in better temperature transfer. These scoops are little funnels and once you push even a little dirt into them, it plugs them good. You won't see it because it's between the fins. I've seen many plugged coils, especially evap coils that were spotless on the faces yet plugged so bad I had to run 4 rounds of NuBrite just to get the air flowing back at rated CFM. That said, you don't get paid more for getting it cleaner. You get paid for getting it done. And this homeowner obviously likes to point the mower discharge at the outdoor unit and not turn off the AC while mowing. It'll look like that again by the end of mowing season. Sometimes good enough is good enough.
I'm a HVAC Technician and I've cleaned a lot of coils like this with the coil cleaner and it helps compressor
No shit it helps the compressor 😂
Love when I find coils like this, it’s pretty satisfying cleaning them,
Same here 💪😎
Careful with tje pressure. You dont want to bend a whole row of coil
I like how the narrative is peppered with anger
Anyone that’s says this is wrong cleans coils the same way. I clean them everyday this way and if you have time to go from the inside out then you don’t have as many calls as most of us do in a day. Nice work
The water pressure and angle you hit the coils is something to keep in mind. You will have issues with all your fins bent over
*Great and Easy to instal **Fastly.Cool** Low noisy*
As an industrial hygienist, the probability that new growth will re-bloom if the material is just laying on the ground is very high. A lot of that accumulation is mold too; not just dust such as Alternaria Alternata (a dust borne mold causing respiratory issues). And 10% of the population is allergic to Alternaria Alternata in the United States. In Arizona greater than 51% is allergic. Sensitization (allergy obtained) when the individual has been overexposed for a period of time and the immune system writes and exaggerated response to the allergen. Why is Arizona different? They are running A/C more and it stands to reason that the well known reservoir (place this allergen is found) is in A/C coils. It is an established fact that indoor air quality is adversely impacted by HVAC systems which are not frequently cleaned. Kudos to workers keeping up on condenser coil cleaning and filter changes. The kiddos developing asthma and folks struggling with breathing problems need your support. Anyway, just a suggestion, vacuuming with a HEPA vacuum without leaving the bulk debris on the ground might be a good idea to prevent rapid re-growth. However; if the goal is repeat business (wink, wink) homeowners might have reason for removing the tops and going in deeper with the cleaning. Knowing that much of that dust is an airborne mold that causes respiratory issues might influence the approach to cleaning.
Excellent. Thank you for sharing your know how. Alot of people say that cleaning the condenser casues problems with the fins later on. I dont buy it. Plus the unit itself and the components have to work a hell of a lot harder if the coils are clogged up, which leads to problems with the components inside of the condenser later on.
I see this alot on home AC units where it just sits on a shallow pad and just gets clogged and bashed by the the lawnmower.
When I installed my new system I went to a local welder and had him make me a steel stand about 2 feet high that i can put my ac unit on. He made it exactly to my measurements so it sits in a channel on the top where they meet and then poured my own pad and then bolted the the compressor to this little steel stand and then bolted the stand to the pad. Been a few years now and the coils are staying really clean and shiny. Much quieter too since its not laying on the pad.
Makes a huge difference in the longevity of the unit.
I can honestly say that when I clean any condenser coil, I always spray from the inside out.
Came here just for this comment. Thx
That’s pretty stupid, you should just spray it from the outside and do it until the water goes all the way through the coil and looks kinda clean coming out the other side
THATS THE PROPER WAY. Spray the opposite way that it's collected. So yea inside out. Smart guy. Now. Spray coil cleaner in it so it eats a whole in the lines and you have a leak and have to replace the unit 😂💯😜😉
@@moneyydogg4318 NO YOU SPRAY THE OPPOSITE WAY THAT ITS SUCKED UP. if you do it the way you say your clogging the coil. Take a class you will learn
Many older units that has no removable panels over the coils, so ur forced to pop the top and back flush
I THINK THE WASH IS FROM INSIDE TO OUT SIDE FOR BEST RESULT, TRAY IT.
looooooolll
Exactly
it is not better.
I have a small room and this AC is very good in I Happy I purchased and will be using again next year.
I personally like to put the cleaner on the outside. Allow to soak for a few minutes. Spray the outside to know all the shit off and follow up by spraying from the inside outward. Adds maybe 5 minutes and i feel confident the coil is clean enough. I also use the flat setting on the hose.
Awesome tip I can see a big difference when the unit is clean
Looks good to me, I clean units the same way and never had any problems.
I love when people try to tell you to clean from inside out but i personally can never get them clean doing that lol. Outside in cleans them everytime at ease with no further issues.
I'm wondering if ... What happen if I don't turn off the unit? The other day I took out the big fuse,then when I put it back didn't turn on. I have to call for service for a short circuit. My a/c have 20 years young. 🤔
@@janicec.9728 did you put the disconnect back in the right direction. If you put so in upside-down they won't engage the contacts on the disconnect.
I clean coils this way everytime 👌
This is why people diy. Appreciate your expertise but the high pressure appears to be damaging coils and in my are there are leaves and debris that collect on the inside. So to a large degree I have the satisfaction of treating a pretty expensive piece of equipment differently then someone who is concerned about the next job, according to some of the comments, especially for my sister’s house, etc. Great post. I’ll definitely consider your points.
If you use foam based cleaner it doesn't matter which way you wash it because expanding foam will loosen all dirt.
I like this video. We got a lot of greens that think they know it all. Good shit brother. Love from Texas!
I believe a professional cleaning that cost money should be done by pulling all the panels including the corners and top. disconnect the wires for the condenser motor and set it aside. vacuum the inside and flush the coil from inside out and outside in. both ways to really clean it. The main reason I clean the bottom out of dirt and leaves is that a few condensers a customer of mine had a very long time and the compressor developed a leak at the bottom where dirt had eroded a hole in the metal. Cleaning the equipment properly is hard and should cost about $200-350 but it is much better than just an outside only cleaning.
👍 Washing from outside is much cleaner and faster than from inside. There is no pressure to properly wash the coil by doing it from inside out. Even on tranes. If the debris is small enough to go inside it will just go through and that’s it. Never understood all the fuss about cleaning from outside/inside 😂
They teach you in school and on the job to clean coils the way this guy is doing it. And not all condenser units have panels on the side, many have open coils you have access to.
cameron yogibear this dude is doing it all wrong. It should always be rinse inside to out. And to never use jet stream and not to spray fins at angles.
On residential units I agree. Nothing in the resi market has thick enough coils to matter. Now try that on a Voyager or something similar you’d be kicking yourself cause now you’ll spend extra time taking it apart to do it right.
Wow the attachment really does the trick!
I always did it this way and never had a problem.
Theoretically, back flushing the coils might get it cleaner with less water. As a practical matter, it probably doesn’t matter. Either way, you want to see clean water coming through on the other side.
Nice "Sweater" on that unit
I wash them like that to and I have been known to wash them from the inside to make doubly sure it is clean. Even on Tranes I wash them that way instead of using a lazy flame and it works just fine.
I only had one side of my coil clogged up and it was tripping the high pressure switch. I have no idea how this one got that bad before tripping it. LOL. Great vid.
Mowing,dry dirt
Would have been nice to see inside the coil housing... maybe prove your "no pushing into the coil" point.
Exactly. LOL. He kept saying "see" but we "see" no proof
Yes you don’t have to push it from the inside out. Although that is the recommended way. When your air conditioner is that dirty anything helps
hi i am from brazil, and i am too a technical conditioning air,here i wash inside to outside to,but congratulations to the work
As long as the coil is doubled up it doesn't matter side clean it from. And from what I saw you have foaming nucalgon cleaner. If i can access the coil i wil clean it from both sides. Keep up the good work john. Ps. Love my coil gun too.
Only on commercial units does it matter due to the thickness of the coil or multi layer condenser coils like carrier on there roof top units.
When it's that dirty and neglected it really doesn't matter if it's pushed deeper in the coil. And it doesn't push it deeper into the coil. it pushes the debris out and into the unit. Which is completely fine
Thank you finally some one else gets it
Don't care about all the arm chair professionals out there! Think of it this way, if you were doing it wrong, how long do you think you would be in business? I've seen a bunch of your videos, and you are obviously still working, so you must be doing something right. Thank you for doing these videos
What do you think is behind the coil a brick wall? Lmao I love it
Nice video John
Coil gun is a must have
Nice. I still drag around pressure washer. I 've seen a product on Johnstone's website that is battery operated. Less clutter on the truck works all the time. Nice demo
We all have our own ways and opinions however, it would appear your method works very well for you. The key would be on the initial rinse, not to spray straight on and push the dirt inside the coil(like a dummy)... We can see that from an angle like you did, the initial rinse took off the majority of the surface dirt.... then the coil gun took care of the deeper cleaning. Good video in my opinion.
I prefer to always hit it with a brush first when it's like that.Knock it right off instead of spraying it deeper into the fins.
It is not "crap" to say flush outward. You flush outward. Secondly, you need to remove the fan assembly to clean the floor. Job half done! You need to flush outward, and inward, after the inside of the housing is cleaned up.
Good service
I have a question, hopefully you can guide me in the ride direction. Info before question: I have an HVAC unit and the coil inside the house is set in an angel. I noticed last night rust is staring to build up on the pan that catches the water from the coils that leads to the drain pipe(s) and the bottom of the coil.
What would you recommend I use to remove the rust that is on the pan and starting to come up the side of the coil?
I do use the coil cleaner form twice a year and I know they remove dirt, debris, and other junk that gets in to the fins. I am stuck with Google searching how to remove the rust. I do not want to introduce no chemicals (acids, anodes, etc.) without hearing from experts in the HVAC field.
very good service of outdoor unit
I hit my coil with a spray like that and my fins flatten down. They are so soft the spray pushes or bends them flat ?
Oh my GOD that was so satisfying
I tried this on a Goodman package unit and that much pressure will bend ever coil fin flat and closed in a few seconds. I have never seen coil fins this thin. My suggestion is to check the resistance to bending of the fins long before spraying from either side as you can do much damage if the fins are a thin as they are on the Goodman unit.
Randy Helouin Goodman are the cheapest units you can get
How on earth did it get that dirty? Jeez! Nice job.
I’ve seen them next to the dryer vent discharge
Looks like grass clippings in it mostly, so I'm guessing that at one point they didn't keep the grass up and were slinging a lot of clippings into it.
I just use water. Let it soak in for about 5-10 minutes, then rinse it. usually does the trick. No charge for that outside of a service charge.
Good job IT'S Clean and ready to go again
Very satisfying video to watch! I need to get myself one of these coil guns!
I,m enginer from indonesia,
HVAC its give me and family live,
Very nice
Pak, ty donk... ini cara semprot airnya sdh benar ya dr sisi luar utk bersihin debunya ? Bukan dr sisi dalam? Mohon pencerahannya. Terima kasih 🙏
Good to tell home owner unit could be low on freon after cleaning
So satisfying to watch!
What is the purple funk-b-gone you are using?
I wash from whatever way is easier... honestly unless the coil is four inches thick its not going to make a measurable difference. If someone wants to blow an extra twenty minutes dicking around with some of the complete engineering blunders of outdoor units out there, than all the power to them.. but me, I'd rather get the job done and move on to the next one. That being said, in most cases it is easier to pop the top and back flush, than deal with the ridiculous side panels and the way they are fastened.
Cough cough.. American Standard
That's the way most companies want their techs to work...bang out the job as fast as possible and move onto the next one. I really hate working like that, I'd rather take my time and do a really good job, but I'm not my own boss so I can't do it that way unless its outside of work. My home unit and those of my family get the works.
Hell i don't even take the panels off unless its a double coil and i still get the job done hahahaha. Some of this extra stuff is too much, dudes love putting on that show for the customer.
Does this clog up the inside of the unit since you’re spraying it into the inside?
There are drain holes on the inside
One risk by spraying from the outside of a dirty coil is clogging the drain holes on the inside.
It won't be long before that compressor goes, I've cleaned units like that and the compressor would only last a week or so afterwards
does this improve heating or cooling efficiancy?
This is great! What happens when you turn it on but the fan in that unit isn't turning? What are the usual causes of that happening?
How much it’ll be a fair price I should charge my customers for a job like this??.. thanks
Getting my coil gun and what soap do you recommend for most coils?
Air Repair Nu-Brite by Nu-Calagon is pretty effective.
Yeah but does it push the dirt deeper into the coil ? You weren’t clear on that .
Aren’t yuu suppose to clean coils from inside out?
what kind of soap and soap dispenser do you use?
John, do you have to use a toothpick to get out all of the stuff you packed into the coils? It didn't show that in the video. Just kidding, good job. I just cleaned mine yesterday, I have the Christmas garland type, worked out well. Love your videos, keep them coming.
Does it hurt the surrounding grass, I flood the hell out of area after but do I need to. Or just spray the grass off.
Use a brush to get most off then cool cleaner on both sides then spray from inside out.
What was the temperature improvement after this ?
I have done it ....depending how dirty the machine is. You can gain between 5 to 9 degrees on my experience.
I’m sure that capacitor was dead or it’s going to be dead soon?. Good way to cause a refrigerant leak to the high-pressure surprised it didn’t leak also surprised him motor didn’t fail
What kind of soap or liquid did you use to clean the coils, did you mix it with anything else?and what's the name of the gun?
Don't use soap
Honestly its all just a show. If you can rinse it from outside in with a hose and see a bunch of water flow from the inside, its cleaning up fine.
They make a cleaners that’s specifically for condenser coils. That is the only thing that is ok to use. Rinse with water after.
@@JustinOnRs yeah, simple green. 🤣
Did he take that thing out of the wall? I hope he doesn't get hurt.
Looks good thanks for the info!
The only time I do inside to out is with a split row coil when you split them apart.
Make more of these vids. So satisfying!
Wouldn't it be better to vacuum the large debris off first and get that fur coat off before using the cleaner gun? Also have you considered a small electric power washer? I have a Ryobi thats about the size of a 15" laptop that does 1600psi.
I would use a whisk brush to get the heavy stuff off, rinse the condenser and then apply coil cleaner, wait 2-5 mins, and then rinse it off. Some cleaners have an acidic substance to them.
@@VannBergHVAC the acidic can be useful to remove the dirt and hair etc... But bad Becuase it sometimes takes aluminium with it
Best bang for your buck IMO
5:08 Absolute mad lad XD
Can you use any cleaner like simple green as long as it suds up?
I clean the same way I have been told by techs that you have to do in inside out, but either way it's still going to do the same thing.
🌸سبحان الله وبحمده سبحان الله العظيم🌸
The jet on your hose is too high and you could bend the fins. Also spray more at steep angle downwards from the top and the dirt just rolls off. You were just blasting it right back into the thing.
Wow! If the condenser is sucking up that much crap, what's going on around it? I live in AZ, the Dust Bowl of the country, and mine is not even showing that much.
What kind of solution (foam) do you use to clean that coil?
I don’t know what state is this but the whip it needs to be water proof, that’s a regular 1/2 flex conduit ...
Best way is to vacuum it first then add coil cleaner or acid removing . I've used degreaser like winter green smells great it many times in the past. Then hose it down, but to each is own right .
Acid ?!
How many ounces of Nu Brite did you use? Thanks!
Great job making people comfortable
Hope your customers appreciate you
As they should
Some guys don’t clean coils
No coil l cleaner in the truck
Whatever works, John. Is the unit back up and running? cooling?..........yes, you say? Great. I just love textbook geeks who service 2 units a week......"you're doing it wrong." I saw my first Sanyo Tri Zone mini split last week...... There were 3 tiny compressors inside the unit, one for each head, neat! Sadly, one of em has died :(
This is the Lazy way to clean your AC coil without loosening screw.
But 👇👇👇👇👇👇👇👇
I preferred clean from inside out.
That is how we AC technicians do.
Push the dirt dust from inside to outside,than follow by outside coil than inside,and from inside to outside again.
That its...done and no dust left behind.
What kind of hose nozzle did you use? Looks like it does a nice job of rinsing the unit. Nice job.
That is a Nu-Calgon coil sprayer. I have one, it's awesome.
