Why Flushing AC Systems Doesn't Work

Scotty Kilmer, mechanic for the last 45 years, shows why flushing a broken AC system often does not work on modern cars. They've made the passageways inside the system so small, that flushing can't push crud or metal particles out anymore. So if your AC compressor blows, it's a good idea to replace the AC condenser, not just try to flush crud out of it.

Scotty Kilmer is a modern car considered 2000 and up?

[@rem-iu2tp]

How many years before the condenser need to be replaced?

[@theq4602]

There is another reason the condenser channels are made so thin. Its a performance thing. For cooling and heating systems surface area is everything. Thinner channels allows for more cooling fins and more channels. This means more surface area for cooling and thus a better AC system. Yes, the trade off is a condenser that clogs easily overtime. But with engineering its all about tradeoffs.

[@jonnyguiry6485]

Scotty Kilmer would you recommend replacing the evaporator too?

[@tdlcraig1]

Quick question. I'm replacing the compressor condenser and drier. Would it be worth me purely flushing the rest of the system with these parts removed?

[@scottykilmer]

changing the expansion valve is always a good idea.

[@scottykilmer]

the evaporator has much bigger holes in the tubes, plus rarely does metal make it that far, it gets stuck in the expansion valve or condenser instead.

[@user-go8cu5ex7u]

Whether you like this guy or not, he is honest and to the point. Thank you Mr. Kilmer for putting on a channel worth watching. Great knowledge and explanation.

[@scottykilmer]

if ac works, condenser can last forever, it has no moving parts after all. Old ac systems should just be inspected for leaks every so often, and fix any leaks before something serious happens. Otherwise , car ac is a sealed system

[@scottykilmer]

they knock from worn bearings inside and need replacing. Squeaking is often a bad fan belt that drives them. But if not, a worn Ac clutch does that.

[@elkillerx]

Glad I watched this. I was thinking of using some A/C stop leak to fix a tiny leak I had but looking at that condenser it seems like it would clog super easily. Oh well. Just another reason for me to fix my a/c the right way. Thanks Scotty!

[@scottykilmer]

jack it up, pull on the driver's side wheel first and see if anything is worn and has play, like bad a frame bushings or torsion bar bushings which those often break.

[@scottykilmer]

many things can do that, but a weak compressor or clogging up orifice tube is most common if it's an american truck

[@mytube3687]

Thanks for this video. Recently my car ac was not working, the compressor was jam. The technician flush the system, replaced new valve, and filter. The ac was running normal for only two weeks then breakdown the compressor again. So they have to replace again the compressor, condenser and valve after removing old condenser, compressor and valve they flush the system and then fixing new compressor, condenser and valve.until now the system is working very well. Thank you for your advice.

[@z31rider24]

James Mosley sounds right. If you don't flush when buying and replacing AC compressor, it's voids warranty. We replaced AC compresor on 2005 Corolla with a new one. Parts place where I picked it up told me about the flush and cabin filter replacement in order for system to function correctly. I believe Scotty was referring to just flushing vs flushing system out when replacing and servicing AC compressor with a new one. Good info.

[@fredmiller1308]

Thanks Scotty, a car guy, but not much experience with AC systems, your opinion is very valuable.

[@workonitm8]

Agree 100 %. The condenser was probably the root cause of the compressor failure. Always replace both.

[@shenghan9385]

What about the evaporator though?

[@steveandrews8301]

@@shenghan9385 Like Scottie said, though, the first component after the compressor is the condenser / filter drier - so that's the one that's going to get the most crap deposited in it, which back up pressure and strain on the compressor. Change the condenser / filter drier.

[@abhay1623]

The compressor is the root cause of tac failure,not the condensor

[@scottykilmer]

depends on the model and make of course, but most cars less than 10 years old are made that way now.

[@robertrussell631]

Thank you so very much Scotty for Your advice and I love your videos, already had the condenser ordered from Rock Auto. My compressor's 20 years old and only making a 30 psi difference on the low side and I ordered one with a accumulator/dryer, seals in the package. Rock Auto recommends condenser replacement as well.

[@jonathandexter135]

Hi Scotty: I have been struggling for years with A/C problems and probably pissed away $4,000.00 or more on my 2 full size chevy blazers and my two 2 door tahoes and this Vid just solved all my problems and frustration. I changed and recharged my 1999 2 dr. chevy Tahoe yesteday and it went from 78 at best now its 56 % on max You are awesome insight is so very appreciated!!! I have a new problem in my 1994 2 door Blazer. I restored the ext. and Int. put it back on the road. When i press the brakes the radio lights go out. I looked on line. People have the problem, no one seems to have fixed it. I have gone through all the tail light bulbs, the wiring and under the dash twice now trying to find frayed wire or ground disconnected. Now have the engine compartment in pieces. Still can't find the problem. Do you or any of your fellow mechanics have any experience with this? Thanks Jonathan Dexter. you can email me direct jonathandexter 1968 at g male dot com. Of course put that together like a normal email. again thanks!!!

[@gswinlerjr]

I once had a 1989 S10 Blazer 2-door. Replaced the rear 6x9 speakers and after chasing very strange electrical symptoms, realized I put one of the cover plate screws through a wire bundle, shorting out several wires. So you may also have a shorted out wire bundle somewhere, after all the restoration. Good luck!

[@scottykilmer]

Almost back to normal now, just a lingering staph infection from poorly done knock out on the operating table. My advice, STAY AWAY from doctors whenever possible.

[@crazyamericangamer7036]

Your forgetting about the orifice line

[@sodhibattva]

Based scotty

[@zezaekrael]

You know Scotty, the long and short of it is, if your modern AC compressor blows, it's just going to really blow for you. Thanks for the video! You've definitely hit the nail on the head here.

[@ralfsautomotive]

I flushed hundreds and never had a problem. If the condenser cannot flow correctly replace it. Continuously circulating machines do that job just fine. If what you are saying is true then tell me why I don't have to redo my work!? Out of hundreds of systems repaired the 2 or 3 that came back always ended up being remanufactured compressors. And Yes, there are times when you have to replace all the Parts but I would never make the claim that you "ALLWAYS" have to replace everything! Furthermore, if that was the case, none of the manufactures would warranty without replacement of "ALL" the parts. Also, when Flushing you need to "always" flow the solvent backwards and never in the direction the pump circulates.

[@elmeradams8781]

The flush will only go through the tubes that aren't clogged. Any holes in the condenser that are clogged stay clogged. Just change them. At the very least the ac will exchange heat better and blow a little colder, at worst your compressor will fail within a week. It's like not changing an orface tube or expansion valve.

[@ralfsautomotive]

@@elmeradams8781 What part of what I said did you not understand? I have done hundreds. Not once have I had a fail from clogged Condenser. Heat exchange is either good or not. Yes, there are times when you have to replace everything but experience tells me that this is not the case most of the time. I don't sell bad jobs! If the flush doesn't work simply replace, otherwise I will save my customer that cash. And the condenser has absolutely nothing to do with an Orifice Tube or an Expansion Valve. If you knew what you are talking about you would know that Compressor Manufacturers will NOT warranty any Compressor if the Orifice Tube and Accumulator/Dryer is not replaced! Thermal Expansion Valves themselves do not have filters so they are only replaced as needed.

[@elmeradams8781]

Same theory. The expansion valve, the orface tube, and the condenser all have tiny holes. That's why you replace them, not that they wear out. I don't know how you can tell if a few tubes in the condenser are clogged or not, or maybe you're saying clogged or not it still works ok so don't replace it. I've wanted to use thermal image camera, I'd bet you could see clogged passages even on working systems.

[@ralfsautomotive]

@@elmeradams8781 At this point it becomes painfully obvious you have no clue! Good luck!

[@steveesposito]

Same thing Rock Auto recommended when I put a compressor/clutch/accumulator kit in my cart. But they also recommend to flush the rest of the system too. I am taking that to be flush the old parts that are staying on without any of the new parts installed yet.

[@henrikaleksandernilsen6388]

These products are made cheaper and cheaper. And yet, they're expensive and break more often, and you as the car owner will gets the bill.

[@judithcopeland6821]

This is right on target....and I'm gonna show this video to a shop foreman at Firestone where their mechanic tried to flush a friends condenser last summer, only to have the entire system fail this year.... Good video, thanks for sharing it....

[@scottykilmer]

no, I have one but rarely use it. My built in mic is dolby 5, so it works well.

[@HaroRider03088]

You said that it was an evaporator you cut at 1:00, but it was a condenser, correct?

[@wendysbrian]

When you say "modern", what year is the cutoff? "Modern" is a relative term and my 97' lincoln town-car could be either/or depending on what one considers "modern".

[@scottykilmer]

different cut offs for different makers actually. Yours is not modern, you could flush it.

[@wendysbrian]

Thank you, Scotty! :)

[@castirondude]

Scotty Kilmer funny how relative "modern" is. To me anything with serpentine belts and fuel injection is modern!!

[@wendysbrian]

True, true.

[@stacey7654]

Hi Scott my honda civic airconditioning do not engage I replaced the condenser fan compressor is new air controller I have checked The pressure like u do in ur videos can u help

[@STIZEN9]

DUDE! I want some of what your having. This video is LEGIT! Makes a lot of sense. Those channels are too tiny to try and move debris through, in an attempt to flush out ac system. Makes a lot of sense thanks bro for teaching me todays lesson. Scott if you did not show me a cutaway of that condenser, I would have never even thought about it. Very interesting.

[@ClumsyCars]

debris got in there, it can come out, especially when you are using a chemical to dissolve the debris.

[@neomatrixfree8031]

Wow. You have a chemical that can DISOLVE METAL FLAKES? While at the SAME TIME NOT dissolving the metal lines, tubes, condenser, evaporator, and so on? Wow. You must already be a millionaire with THAT invention! Go sit down before you hurt yourself.

[@ClumsyCars]

You're an idiot, The End.

[@paradisemace1]

Unhook both hoses on condenser... flush backwards with B12 chemtool... flows like new.

[@dallen122758]

My uncle turn me on to B12 chemtool years ago. I use to use it in the gas tank all the time but stop using it on my new car with fuel injection I now use Lacus fuel injection cleaner.

[@ClumsyCars]

shhhh, that doesnt get youtube views. ;)

[@scottykilmer]

generally a wearing out compressor does that, if you turn the AC off and the noise goes away, the compressor is the culprit.

[@citizen037]

That is a micro channel condenser. It is not made to be cheaper, it’s made to be more efficient. The increased surface area for the refrigerant allows more heat transfer.

[@scottykilmer]

actually it can damage the new compressor if any old flush is left in.

[@MrTTqUaTtRo]

Scotty, you truly are a car nut! Love your videos man, you're my go-to any time I search for a DIY. Very helpful videos, keep it up!

[@cjmrichards]

2:30 “it’s a good idea to change the condenser too” or did you mean evaporator?? Because right after that you said you’ve seen too many guys come back months later having to replace both the compressor and the condenser. I have tested and tested my ac system with the manifold kit and both gauges read exactly the same number, and the compressor runs but doesn’t blow cold air, so I’ve come to conclusion that it’s my compressor that needs replacing. I have bought a brand new compressor and condenser and im about to replace it. Just want to make sure I don’t need to replace the evaporator core too. That’s one hell of a job on my 2013 corolla, have to damn near take everyyyyyy thing apart in the interior to get to it

[@craigoldenburg2584]

u r so right those condenser types are called micro condensers fail and leak often manufactures way of selling more they are on house air units too

[@chrisg5326]

Scotty, if you do not flush the system, how can you figure out how much oil is missing and how much to top up? Any suggestion? Thanks

[@lowlow643]

scotty, i have a 1996 chevy caprice, i went through 2 compressors after original one went out,all i did is changed the compressors with the acumelator and the orifice tube, but never changed the condensor its the original one,now my compressor needs changing,shall i buy a new condesor or that 1996 condesor have big fins or small one like you showed here ? million thanks again scotty no one does what you do here.

[@autodoctor6512]

Always a good idea no matter what car make or submodel to check for TSB,s and (restrictions on use) tech feeds, data sheets etcetera. Because while yes thats true in most cases; some allow it and a few require it to be flushed with SAE. approved fluid. Although they are few. And yeah I actively avoid using dealer parts if at all possible.

[@RockerDave12]

Thanks Scotty for the heads-up warning about AC flush. I was planning on doing it. I had an accident where a storm blew a tree branch right through my front grille and poked a hole through my condenser. I replaced my condenser with a new one, the drier too, and the compressor too, and was planning on flushing my AC lines and evap with flush as a precaution against sludge buldup. But OK, Scotty says don't do it. OK, brother. I won't.

[@rosen9425]

WOW those holes are so small. Are we going into nano-meter scale now or what!?

[@Boz1211111]

Efficiency Less material is cheaper in some way But more efficient at what it does And lighter for a vehicle to carry Win win win

[@MrUbiquitousTech]

Just making the crap disposable.

[@GTR0419]

Lower cost (higher margin) plays a part. But weight/fuel economy and crash force dissipation (for some parts) are in play. That said, my Jeep Commander was in a basic fender bender. The fender was done and there was damage to all kinds of plastic. However, it was still derivable and didn't really look that bad. Repair cost paid by insurance - 6K!

[@dallen122758]

Thanks for the information I did not know about this so now when the compressor goes bad this is another part that need to be changed a long with the filter dryer. My question is, is the evaporator made the same way and will it clog like the condenser? Thanks for your time to help us poor boys out and saving us time and money and more trouble down the line.

[@Vinnybrain]

Hope you feel better Scotty...were all pulling for you!

[@spelunkerd]

Am i correct to assume that when you replace the condenser you don't need to flush because the condenser is an effective filter, protecting the expansion valve and downstream structures? Or, would you flush the rest of the system anyway?

[@sam111880]

And i would say a good way just use condensation drain and interior vents to supply the foam mildew/ mold product to kill off bacteria...and bring the vent system back to new. (But was curious if the ac flushing kit that was once used to remove clogs still has a uses in other areas like cleaning the vent system.

[@abellynch1888]

Hey Scotty, Im getting a Condenser, AC Lines, and compressor from junk yard for a 1989 Mitsubishi Mighty Max. Apparently they dont make or rebuild condensers for my truck anymore. Will flush work on a 89 condenser?

[@scottykilmer]

pray it's just low refrigerant, cause tons of other things can do that too.

[@jaybartalino9635]

glad i did not flush mine great video

[@scottykilmer]

because i drive my cars for decades and would rather fix them than replace them. if you like throwing money away on cheaper designs, go right ahead. It is not more efficient cooling, it's just a cheaper way to make them work the same. the smaller holes actually strain the compressors more and they break down quicker that way.

[@rbarr1200]

Thank you this has helped me stop thinking and stressing over what I should do. I'm buying a replacement.

[@tonysabatino4725]

Okay! When was the cut off time about when flushing became no longer helpful? Or was that when 134 replaced 12?

[@Lorinidaho]

I'm wondering that too. Did you ever find an answer? I've got a 1998 Town Car with ac issues

[@WoIverlne]

It's not that the holes are too small to flush out, it's that cars that come from the factory using r-134a refrigerant use a parallel flow condenser instead of the long winding single tube that was used for r-12 condensers used. That's also where the myth that r-134a isn't as good as r-12 came from.

[@fargeeks]

i heard that r12 is actually very dangerous to the atmosphere so im guessing by somehow continuing use of that global warming will become worse

[@zeke112964]

So your saying you can flush them?

[@E150GT]

no you cant flush them. R12 is more efficent so it didnt need as many passages as r134a. R134a is not as good as R12 when it is used in a system designed for R12. If you ever do a conversion you might find your system sucks because you would need to change to condenser to a more efficient version designed for the new refrigerant.

[@eltrouble]

If your old compressor was worn out, the new compressor would cause increased load on your engine, which is why it idles poorly at a top. I would first try cleaning out your idle valve, but if that doesn't work, replacing it is a good idea. Also check the condition of the spark plugs and the rest of the engine to see if they're in good shape.

[@Closeoutracer]

Would replacing with an Older condenser with the larger tubes be a viable alternative ? Say replacing with a condenser off of a late 80's truck?

[@jbarthol]

Agree with most of the video, except the part where you recommended getting cheap Chinese parts. I personally will shop around for a decent name brand one before going that way. Cheap Chinese parts are just that, cheap. More often than not they develop cracks, and leak out. Also, you should do a video on those cheap refill bottles, and the problems they can cause with systems that require special oil. My 05 Jeep Cherokee/Liberty is finicky about the oil that you put in the a/c system.

[@HDGuy]

Do you think this applies to a 2005 Colombia Frieghtliner truck?

[@chieftp]

+HD Guy I had one rupture on a mack years ago. the shop replaced it in about 2 hours. just a few bolts and the 2 refrigerant lines. I told them it had ruptured and pointed to the oil that sprayed all over the place. "that don't mean nothin" the mechanic said as he prepared to charge it. started the truck up and it sprayed all the new stuff out. "well, I reckon it has a hole in it." duh

[@willa498]

If you replace both do you still need to flush the system? To get anything out if the lines or has it pretty much all been caught by the condenser? And do you need to replace the evaporator?

[@izzzzzz6]

Scotty you have an awesome voice! You should do cartoon voiceovers. Not saying you shouldn't do videos keep up the good work!

[@martinluther4093]

If someone is replacing the condenser, compressor, dryer and expansion valve, isn't it still a good idea to flush the hoses and evaporator?

[@terrenceg3257]

You say these condensors with small passages are in modern cars. What year do you consider is a modern car?

[@eaglekeeper6056]

It's not to make the parts cheaper. You said it yourself in the video, it's to allow more surface area for the refrigerant to dissipate it's heat. Back in the day we didn't have the technology to mass produce to such finite tolerances.

[@scottykilmer]

Jeff Watson true to some extent, but it is cheaper to make these, they are smaller and use up much less aluminum than the older ones did, and makes flushing impossible so you have to buy a new one if you want an AC system to work right once the compressor breaks and needs replacing.

[@TofuInc]

Pull it off and back-flush it no need to replace a perfectly good condenser. You should replace the o rings while the system is open anyway and remember to replace the filter dryer. Most of the time failure is due to acid build up in the system from air/moister not being removed rather that crap being left in the system the filter catches that.

[@scottykilmer]

ah, but if the compressor blew and sent parts into the condenser, you can't flush that out of these new ones. So it depends what actually broke.

[@TofuInc]

Usually it's the compressor that goes, by the time the system is flushed out there are so many other paths for the refrigerant to go through a few block passage ways aren't going to make a difference. Replacing the filter dyer and getting the moister out is much more important. Any bits left will eventually end up in the filter that's why its there.

[@larryholloway9942]

Scotty Kilmer yeah in the warranty business they call that cancer!

[@digimon916]

what would you consider as modern. lates 80s up? 90s? 00s? would a good rule of thumb be that if its close to the size of the condenser you showed in this video, its too small and cant be flushed?

[@booyakashaboy7250]

Hi Scotty great vid. I have a 07 2.4 Rav4. Shop said it has a bad compressor. They said all it needs is a system flush and a new compressor but from what you've shown it should get a new condenser too. I'm supplying the compressor (kit includes compressor & clutch, receiver drier/accumulator, expansion valve/orifice tube, PAG oil, seal kit). To keep my compressor warranty it states the expansion valve must be replaced. Its hard to get at mounted to the evaporator under the dash. Shop said that alone is a 9hr job! My question is if the bad compressor has contaminated the system, what are the chances that the contamination took out the expansion valve? I would think the dryer, accumulator, and condenser would catch most of the debris that would pose a threat to the expansion valve located downstream in the system. Am I wrong to think this? If not I'd like to leave the expansion valve alone (understandably voiding my warranty) and just replace the compressor, dryer/accumulator and condenser myself. Have shop flush lines and evaporator. Close the system, vacuum, and charge it. Does all this seem like a good plan of attack? Any input would be greatly appreciated.

[@PARAFUN12345]

Mr. Kilmer, Do you consider my 1996 Olds Aurora 42,000 actual miles a modern car, the compressor has a rattle, I plan to replace the compressor, orifice tube, pag oil and accumulator... evacuate the system and recharge... and will replace the condensor if you reccomend... Thanks, Scotty

I have a 2008 honda pilot. It has a bad compressor. I plan to change both compressor and the condenser. Based on this video it's best to changed the condenser because it may be clogged. Does evaporator need to be changed as well?

Ok, how about flushing the evap coil with RX11 flush? 06 Dodge Ram 2500. Going to install my 3 rd new compressor. This time I’m putting all new lines, new orifice, new condenser and new dryer. Not really wanting to take apart dash to install a new evap coil. Is flushing the evap a reasonable option .

Are the holes in the condenser on my 1992 Corvette big enough to flush? My compressor needs to be replaced, it seizes during hotter weather.

Yup its time for me to get a new condenser...thank you Sir.

Flush won't take out metal debris A.K.A. crud, but it will get the oil out of the system. Having the correct amount of oil is just as important as the correct amount of refrigerant.

Hey Scotty I have Jeep GC 2006. It has been vibrating and today it catch on fire!! it was under the engine driver side. Thankfully it was a minor fire that I was able to put out... but what caused that? Aside from that it has horrible gas millage, windows stop working, vibrates and now catches on fire? what is going on?

Funny, I've actually never heard about this procedure before. Just the usual system evacuation.
