How To Clean A Mini Split Air Conditioning Unit 

I am so thankful for Mr. David and all this information, because i am learning a lot. knowing what to look for and what to expect. Thank you again Mr. David Jones.

*Love this unit! Using upstairs in my sons bedroom **Fastly.Cool** and he’s finally able to be comfortable upstairs without me freezing downstairs. Works for more sqft than expected!*

Thank you for your video. I have a similar unit here in DR which has never before been cleaned since it was installed about a year and a half ago. Thanks again.

Thank you David. Great video!

That's nice, but I just wanted to point out that depending on your model, you can definitely deform the cooling fins using a hose sprayer--I've done that to mine, and now need to make sure to use a pretty weak stream. Also, the condenser is only half of the system--you need to clean the air filter at each head unit and clean out the condensate discharge...

Thank you for explaining.

Thank so much for posting these videos you are great 👍. Hope all is well God bless.

Very informative video. Ours hasn’t been cleaned in years and the back had a decent amount of dirt / debris. My hardware store was closed , just used a hose and it nearly took it all off. Thanks for posting !

Thanks for this informative video. Loving our minisplit system.

Just did this thank you. Wasn’t hard at all! Mine was actually fairly clean even after 5 years.

Thanks, super helpful!

Thank you!!! Made my job easy and my unit work better

Great information

very nice and simple techniques idol, thanks for sharing

These units are quite new to Americans. You guys really also need to remove the top capping and the extractor grill and hose from the inside out (avoiding the compressor circuitry) so you dont push debris inside the unit.

Thanks for this!

Thanks for the video. Problem is where I live the so called 'servicing' of an air conditioning unit both indoor and outdoor is just wipe visible surface with a wet cloth and that's it. If you want something done well you have to do it yourself.

I like this Guy good videos, Thank you 🙏🏼

Thanks for the video

Thank you

Excellent excellent thank you very much

Thanks!

Seen split row coils on the outdoor unit , to properly get a good clean open the top and check if u see 2 coils side by side and if you do would have to separate them a tad and wash in between. Just a heads up

Great video but with a little more preparation you can clean more of the coil. I've opened up my Mitsubishi outdoor cabinet and the coil extends around the corner, so is an L shape looking from above. If you remove the top panel, then the panel opposite the electrics end, you will be able to spray and rinse more of the coil. One video I watched suggested using car-cleaning detergent, but not dishwashing detergent (if you can't find coil-cleaning detergent).

شكرا جزيلا....☺️

Thanks

I like your videos they are very informative. I have an air handler in which the fan runs when the ac is on but not when the heat is on. When the heat setting is on the fan doesn’t work on auto or the continuous setting. When I go to the cool setting the fan comes right on as expected. Do you have any suggestions? Relay?

Thanks so much for this! I have the Arm & Hammer leave-on foam. Should I clean with a wash-off cleaner then rinse with a hose first, then spray the leave-on and just leave it on?

Great video David! where'd you buy the coil cleaner? do they have to be specific for AC? Thanks much!

Great video David,keep up the good work. Would love to see you post a video on how to clean the evaporator coil inside the house. Just did mine and removed lots of mold but it messy and maybe you have a better way to clean them. Thanks for everything you do for us newbies out there!

Thank you for this informative video. I just ordered two cans of the cleaner. Also I love the term you put into the description..”able bodied homeowner”. I will begin to use that term more during my conversations. Thank you again!

Hello, I have an Everwell 19 Seer split unit ac that has never had their coils cleaned. I will definitely do so after watching your video. Thanks so much!

Anything around the house i can use as a spray to saturate it before i hose it out? Thanks

Any brand that you recommend for the outdoor coil cleaner?

Thank you Mr. David jones, for that information. I had a split unit install a year and a half ago. How often should it be clean?

Can you do a video that shows how to clean the inside of the mini split unit

It would have been good to tell a little more info on the cleaning fluid , can you use the aerosol spray foam? Where can I get the bottle liquid spray .

Great video, whats the name of the cleaner please

Thank you so much for this video. Very helpful. Does the unit need to be turned off to clean it?

Steve Lavimoniere, RU-vid HVAC God, says those coil "cleaners" leave a film on the metal impairing heat transfer. He says all the pros know to just rinse those coils with water. Nothing else, just water. Hope this helps all the mini-split owners wanting to extend the life of their units.

What's a good home make coil cleaner?

What brand of coil cleaner did you use in this video? It did a great job.

i think you are supposed to take the circuit breaker out and turn it around 180 degrees and re-install, should now say "off" on the left. Looks like you are setting the circuit breaker on top of the box expossing 220volt contacts. incase this is not so and you are doing it correct . you should show this in detail so there is no doubt for someone that does not know.

I have 2n questions. 1. What is the "coil cleaner" made of? and 2. How long after washing do you need to wait before turning power back on? Please respond.

so does it negatively effect the inside components when spraying from outside into the unit?

Thank you! May I ask, specifically what cleaning solution should I use for the outside unit, and what solution can I use to spray on the interior unit’s coils? Also, do you recommend using computer compressed air to blow dust off the coils and filters? Thank you.

How can you clean the fan blades?

Every service tech gloves when the homeowner tells them how they saw a video online... lol

Hi! I live in Canada. Would you recommend to cover my outdoor unit during winter or should I leave it uncovered?

Thank you. But couldn't pick up on "Outdoor..........Cleaner" at 0.05.

How often should this be done?

Thanks for the video I took my grill off to clean the fan because I could see it had a lot of dirt while I did so I could see the coil on the inside had some pretty nasty spots. Unfortunately my system is mounted on a wall so I can't exactly clean it like the way it's done in this video. I have the Samsung service technicians come out a few years ago this was pre-covid I think they did a really good job on the internal unit because they disassembled it And removed some cylindrical part and sprayed it down with some hand pump. But when it came to the outside unit they basically just sprayed the hand pump spray from the outside towards the inside. I was a little bit surprised that they didn't actually take the machine apart at all for the outside. Also they definitely did not spray it down with water afterwards. Looking inside my machine I can see where the corrosion may eventually be forming. Especially on the bottom of the unit I guess it's sort of like a drip tray. That seems like it's going to start falling apart before the actual coil itself does. But I know from using a dehumidifier that these machines work better when the coil is clean. I'm in the process of trying to locate some coil cleaner so I can do it myself but unfortunately this country I'm in products are not always readily available. So far most of the products I've seen for cleaning air condition systems are not for cleaning the coil. Instead there's some sort of spray that for example has a scent like orange that you're supposed to spray into the part where the air comes out. I saw one with foam but anyway I'm going to have to keep looking. I plan to call the service technicians again but I don't expect them to do any better job cleaning the outdoor unit than the first guys did. Sometimes if you want things done properly you have to do them yourself. I learned this lesson after I had some guy put some waterproof paint on my roof. Then after I had a proper ladder* so I could get up there myself I bought some of my own waterproof paint, and I realized the stuff he used was water down even though it says on the package that you're not supposed to water it down. And of course he did as short of shotty job but I realize that when he was done after about only 20 minutes. Meanwhile I spent several hours over the course of a few days up there putting a few proper coats down and giving them enough time to dry and cure in between

You honestly should take the front panel and top panel off and spray from the inside out because that is the intake air side

Can you spray in the front fan/blade area?

Mine blow out so much dust that it’s on my walls and I cleaned the filters I feel the whole unit needs a good hoseing down and do I need to shut off electrical stuff to do it

Why wouldn’t you take the two panels off and clean the unit completely? Our Mitsubishi units are so simple to break down, just a few phillips screws and the top and front wrap around panels come right off allowing full access to the unit.

Why is your drain hose routed out the backside of the unit directly over the coils ? That is the reason for the discoloration below it. The drain line should never be able to rin down the coils. Going to shorten the life of those coils

Do you need to remove the fan motor before you do this ?

Always spray from top so it drips down as u work ur way down

What is “coil cleaner”?

What about the inside unit and its coils I call this half assed

What’s the chemical solution to clean it?

Thanks but you need to tell us what you used as cleaner.

Did you just use soap and water?

Well, I'd avoid using chemicals that may cause rust or corrosion.

If you have to tell your Hvac technician to do a proper PM, he's not a good technician and you should call another company

You should never ever spray into the unit, spray from in out.

Never seen someone use two hands with a pray bottle lol

Don't mount them on a ground level pad and they will stay much cleaner. The unit should never have MUD on it. Mine is mounted 2 feet above ground, it's common sense. I also don't have to bend way over to gently (without bending fins) clean it with common household Lysol liquid and a toilet brush. Sheesh!

"kloe cleaner" ??? what the H is that?

What type of cleaner? I swear he wasn't speaking English when telling us what type of cleaner to use

Wrong................clean from the inside out! Remove the top. Many units have a second coil which cannot be reached from the outside.

Ya, no. What's in the coil cleaner. It's not magic. Tell me what's in the cleaner.

Thank you
