How to Clean Your Mini Split AC Condenser - Make it Cold Again

I still dont understand why they have these windturbines outside of their house, I mean like on the picture... small thing what it do for the house...

Thanks for sharing looks very simple

Yesss! The hidden screwww!!! Ive just been hangin' outside sprayin it gently for half an hour, looking like I have my reasons for peeking under the lid.

Thank you, ductless split wizard.

Fantastic! This is exactly what i was looking for. Thank you 😊

Nice work but better to have the unit on a stand and not so close to the floor, Thanks

I had mine serviced the service person didn’t clean it he turned it on let it run for about 20 mins checked the temperature & he was done!

Superb video mate, thank you very much. 👍

Holy Dooley, thank you, very helpful 👍🏾🤎

What a crock...just hose the COIL,Nothing more

Thank you. Is difficult to find video teaching us how to wash the condenser.

Thank you

Thank you so much for sharing this!! I’ve been struggling for months in the heat. Finally found your video and tried and IT FIXED THE ISSUE!! My AC is now cooling. Thank you again.

when you replace a screw into anything you have opened, place the screw into the hole and with the oppropriate screwdriver, first turn it anti-clockwise ( lefty-loosy ) slowly and you should either hear and/ or feel the screw click into the original starting position. this procedure is most important for plastic objects, so as to stop cross-threading. P.S. you may need to repeat this a few times, but you will get the the idea.

i dont have ac. but then im a cheapskate i open a door or window!

Your blocking proper airflow with the linesets in the way.

Thanks!

Thank you! After your mini-split video a few years back I installed one myself. After this video, I realized that my HVAC company only cleans the main AC unit that they installed, so this was exactly what I needed to do it myself. The foam works great and it’s super easy to do.

Get rid of mulch around unit and put marble chips down

I'm impressed with how easy it is to clean a mini split condenser. Which the central compressor we had from the 80s, you pretty much had to completely dismantle the thing to get to those coils. If I got a mini split, I think I'd like to put it on top of cinder blocks. Our window until never got as filthy as the central compressor, and I think it's because it sits at ground level. Even setting it six inches higher might help a great deal in keeping the coils clean. In some cases, they're just mounted on supports on the side of the house like a few feet above the ground. I never saw any point to waiting until it was completely dry to use it. It's made to get wet, and it's self-drying. When I'm just giving the window units a quick spray, I'll actually just leave them running. If you hear the motor spin down, just lay off the water to let it spin back up. Don't set them stall out. Window units are designed to retain water, and the fan blade slings the water onto the condenser coil extra cooling. The fan has to be powerful enough to sling that water. The water also helps cool the fan motor and compressor.

Can't take this seriously. I stopped watching when I saw the outdoor disconnect was a breaker, and the mini split line set was coiled up.

Very helpful going to do this at the start of each season.

$400 to have an AC unit cleaned? I pay $20 per inside/outside unit for a complete strip down and pressure wash.

I just used spary foam, cheaper and made way more foam than your wussy can did. Now my AC will stay clean for ever whooot.

Using a hose can damage fins, use a hand sprayer

Thanks for the great instructions for the outside portion the mini-split. It would be most appreciated if you'd show how to clean the interior portion - especially the blower wheel and how often is that recommended?

Much better if you remove the fan blade and spray from inside. Pressure washer without the nozzle installed is the best way to clean it without bending a fin.

Why is your condenser located in a mulch bed? Seems like a bad location.

400 dollars to clean one aircon?why so expensive?

Can i just use compressed air to get the dirt out and blow the air to through the duct

@SilverCymbal best method for ACs installed in desert areas. Sandstorms and heat makes it very dusty😅

Awesome tutorial! Thank you!

Just wondering...if that foam (and other brands like it) say "No Rinse" why do you choose to rinse? Thanks. Tim

Definitely do not spray cleaner or hose water on or near that box tray very top middle under the cover.
(It’s the computer, and H20 don’t mix and voids the warranty)

Thanks, mate.

Say anyone that has a mini split with heater did you notice anything different on your electrical bill? Winter cold months is it cheaper and perform better with the mini split heater than you whole house heater or space heaters? Looking to get 18,000 btu in our one big area the family room, dinning room and kitchen which is a rectangular room about 550-600 ft. Then for the master and two other bedrooms I’d need at least 9000 btu units in each bedroom and maybe a bit more but’s in the master which is about 20x25 plus bathroom. It’s a small house with hot flat room that I need to decide what to put on its black tar and paper roof to reflect the sun from heating it up so much. I rolled on some white sun coating stuff a few years ago over the r over the main Pat of the house were in during the days and evening which really cut down on the heat soaking down from the roof into the house, but it’s wore off and like it was never done. So need suggestions anyone would be greatly appreciated. Well if you read all this that is very cool. With thanks

Thank you for the great video.. I’m shopping for a mini split for my 1500 sq ft home here in Wa. Where as everyone knows it rains a lot so my concerns are I’d think for it to last longer would be to keep it from sun beating down on it and same for rain. Is there any concerns about building a large cover with good size vents so it gets plenty fresh air and to keep dry and from sun exposure?

That’s a good cleaner. I use it on my trucks radiator and intercooler

It's unbelievable it costs so much to have a professional clean a split a/c. Here in the Philippines it costs about $15 though they only use a pressure washer and a shroud with drain hose. Most Westerners also don't know your car A/C also needs washing occasionally.

Why didn't you cover the electronics?

Been doing air conditioning for a few years now and approve this message. I think the cleaner isn’t really needed. Just wash it with water from the inside out and you should be good.

Had split system installed few years ago and i live up the mountain area and extremely cold 🥶 during winter season

Last year for the first time my unit stopped working during an extremely cold night running on heat.

The inside unit displayed DF

I quickly did a search online and turns out these units can’t handle extreme cold temperatures and goes to sleep defrost mode kicks in. Usually takes about 10 minutes then kicks back on.

Thankfully got wood heating.

Yes Kentucky fried chicken.

Would a dirty outside unit cause that “wind wooshing” sound inside?

I have a request for a video how to change transmission fluid on a pickup truck

Great as always! Thank you. On the topic of airflow, the coiled up line-set behind the condenser are restricting some of that airflow. Many DIY folks that have installed this or similar units have the same issue. It would be a great video to see a DIY custom line set length, evacuation, etc… Obviously this wouldn’t work if the line set comes pre-charged vs the outdoor unit being pre-charged.

Quick comment. I noticed your excess line set is sitting upright. In my Mr. Cool manual it says that the excess line set should be placed in a horizontal position, parallel to the ground. Did you manual/instructions say otherwise?

Good video, quality content.

I'm curious, however, about the placement of your system: on the ground, on a concrete pad.

I recall last winter you had an issue where you got something like three (or more) feet of snow over a couple of days. That would totally bury this unit.

In an area where you get so much snow, shouldn't the exterior unit be placed off the ground by a couple of feet?

Moved into a home & had the pros come out & do a maintenance for the inside & outside units of my mini split...yep $700. Later that the fall a tiny mouse got into my outside unit & got killed by the fan trying to escape. THIS TIME I decided to get the mouse out & clean the entire outside unit myself. I disabled the power, took the top & front grill off, vacuumed & hand wiped the inside down ( took photos in case I forgot the order of putting it back together). This summer I will TRY and do the COILS ...Thanks LOVE your videos !
