Highwall Ductless Blower Wheel Cleaning

In this video, Sam and Jake with Kalos Services show the steps of a thorough highwall ductless blower wheel cleaning. They remove and clean a Mitsubishi ductless mini-split blower wheel.

First, you must lift up the shroud and removes the air filters from both sides. Then, remove the front cover entirely and slides the horizontal vanes right out. If you want to remove the face of the unit, you have to remove plastic clips on the bottom to expose the Phillips-head screws underneath. Once you remove the screws, you can remove the face.

To access the blower wheel on a highwall ductless system, you have to release the drain pan and let it angle downward. (Remove water from the pan beforehand.) To remove the blower wheel, you will need to remove the set screw, remove the screws along the side to move the coil out of the way, and then pull the blower wheel out.

You can clean the blower wheel outside with a hose, sometimes even using a mild, safe cleaner like Refrigeration Technologies Viper EVAP+. Allow the blower wheel to dry fully before putting it back.

Once the blower wheel is dry, insert it back into the unit and reverse all of the steps you took to remove the blower wheel. Then, you can clean up the job site, finish up the customer communication, and go home.

The place I rent has this unit but with just two screws hold the front on. It’s been 99 and up here in Florida. My little place just wasn’t cooling down. Looked in the unit and saw this solid black mass. Followed this video and after an hour of cleaning the blower it’s like a whole new unit. So cold and so much air. Thank you guys.

Swear this was better than ANY cleaning Mitsubishi Split video ever made! Why? IT WAS FAST AND SIMPLE!!!

Thank you! Had no idea about air conditioners. It was dripping onto my wall, most likely from a blocked evacuation duct (it was newly installed last winter, not sure how that happened). So what I did was disassemble the front part and tilted it some more so that it dripped from the blade fan, into a large bowl. It got us through June like this, when one day we noticed the bowl stopped filling. The evacuation duct cleared itself of the debris, and now the condensation drips outside again.

Now its September, and we are on the last days were we need the AC. I managed today to put it back and take out the paper I slit in for tilting it more. Learned a little bit about how air conditioners work, and fixed it myself. Feels great. Hope you have a great day!

Great video, saving people money!
You're providing a great service to people... I've got an HVAC buddy and I asked him to check the pressure of my freon. I told him I'd read that low freon will cause freezing over. He said yes, as well as dirty filters and blower wheel.
I'd never thought the blower wheel would have such an impact, but I'd also noticed diminished air flow... waiting till sunset to pull blower wheel. My filters have never really been dirty, each time I cleaned them.

THANK YOU!!! —Your video just saved us hundreds of dollars as the installation tech said, “There is no way you can clean these yourself. It’s just too technical and could be dangerous. We recommend you getting us out here every three months…no later than 6-months between cleanups. For your four units it would be $500, —but we’ll give you a discount to $350.” $1400/year Vs a couple of hours and a pack of Clorox wipes. Actually was fun once the first one was done!

This video was so clutch, literally followed step for step and did the exact same thing on 1 of my units. Literally going to be the training video for us lol.

My AC guy charged us $600 to top up Freon and said it would cost $13k to fix. The unit simply needed cleaning. I’m a 63 y.o. Woman and even I could do this. THANK YOU!!

Thank you, this is the best video on removing the blower. Quick and to the point with all necessary information. I can clean the blades faster and more thoroughly by removing them than by trying to clean them in place, even with the few extra steps.

Thank you so much for this video. One of my units just wasn't keep room cool. Hardly blowing air compared to others. Following thos video I took it apart and gave thorough cleaning....it was nasty...I mean NASTY! Blower wheel very gunked up so air couldn't fully pass through. Working great now. Thank you!

[anubisjr]

Thank you so much! This made a huge difference in my coffee shop. I had no idea the fans got dirty but when the filters were clean and there was still little air coming out, this was the answer. Again, thank you!

I’m so mad! My until stopped working last night. I have either this exact model or one that’s super close to it. When I got it, they told me they are super easy to maintain, just pull out the filter things once ever few weeks & rinse off, put back in & that’s it. Water was dripping, so I tuned it off & left it. Came to YT & found this video. I didn’t know the blower wheel needed cleaned like that. I live in the country where we get horrible wind (Eastern Oregon), it’s hot AF in summer & always dusty. I just looked at mine & that thing is GROSS! It literally looks like dried mud on it. Thankfully my husband it’s good at things like this & is gonna take it apart now to clean it. Our one upstairs stopped working last year. I bet the blower wheel is so bad that it can’t rotate. I’m so thankful you did this. You’ve saved us a headache & a lot of money. Thank you!!!

[dallasburns]

I wanna thank you so much, … I have the same exact one, and that totally saved my ass, lots of nastiness, mold, and grime in there. Thank you again.

[DexterWilson-md]

I'm out in the field right now and this was a such a informative video. I feel much more confident in removing the blower wheel. Thank you guys

[jkid]

Had to rewind this about 100 times at least during my cleaning session lol

[jlinkels]

Very useful video. Thanks. I have an LG with the same problem. Your instruction confirm the approach I took and my reasoning. The only problem is that in the LG the are obviously some other retainer clips hidden here and there. Preventing me from lifting the evaporator. But I am on the right track. Thank you.

[jimmyprater]

Thank you, I cleaned the blower wheel after watching your video, it’s a Senville Leto from Amazon, super cold now that the air is moving again !

[mysorenataraj]

I did clean it without dismantling the vanes. The roller type blower has thin plastic vanes. Heavy accumulation of dust and dirt cake the vanes. They can be easily cleaned using a mascara brush very well.

[dominicg]

Thank you. That was a very short, to the point, and informative video.

[jericosha]

Thanks man. I always feel like I'm going to break a customers unit. Good tips, very appreciated.

Always used the drop bag pressure washer type set up. Which was always a mess and time consuming. Pulled the mini split blower for the first time and it’s a lot easier. It takes some finesse. Putting everything back in place but yep.. gonna do that from now on.
