Ductless Mini-Split: How to Take Apart & Clean DIY (Mitsubishi FH High Wall Series)

See a demonstration of taking apart and cleaning the Mitsubishi Electric FH-series ductless minisplit heat pump. Thanks to Garrett Beneker of Lincoln Air in Phoenix, AZ for sharing his expertise, and to Jim Clark of Mitsubishi Electric Cooling & Heating for introducing us!

Yes, this is the clearest, most comprehensive video. All the steps are there. So grateful!

I have searched videos everywhere online. I have 2 FH series 12000 BTU mini splits, so this has been the best video I have seen. Companies out there charge a fortune per unit to clean them and they are not as thorough as these. They spray, rinse and drain it into a bucket without taking the unit apart. Thanks again for an incredible video.

This video is exactly what i needed! Thank you for being clear with every step.
Ours was so nasty! I jad no idea.
Funny story, i got everything reassembled and then when turned on, it made a noise... I hadn't tightened the screw holding on the blower wheel. I had to completely disassemble again. At least ot went quicker the second time.
Thanks again for a clear video.

Thank you so much for this video. Tilting the coil out of the way a few inches and removing the wheel made it possible to clean this MSZ-GE thoroughly like new. I could not find a tech who wanted to spend the time doing this like you guys, DIY'd it, and got the job done thanks to your video.

A very lucid and well shot, well explained video. Calm, nice speaking voices and no excess verbage. One of the best I have seen while combing through youtube for how to dismantle, remove the blower wheel and clean the coils with the evap cleaner foam. Exactly what I was looking for. Thank you!

I took my time with our unit. Took a couple hours because it also ended up leaking all over the floor and other items. This was a great tutorial for what I needed to get the job done. Last time this leaked inside the house I used a bucket wet vacuum on the outside condensate line. For whatever reason ours gets clogged often. Seems like the whole unit should have been designed somehow so that this level of cleaning wasn't necessary.
At any rate, special thanks to you guys for the great video. Very much appreciated.

You actually explained that in more detail than anyone else thanks mate from Australia

GREAT VIDEO ! START HERE IF YOU ARE TRYING TO CLEAN YOUR OWN UNIT. thanks guys for this video, Garret is one of the few Mitsu service guys who really knows what he's doing. Diamond indeed !

Finally, a good simple video! Mine started leaking the other day. Maintenance, hasn;'t been running calls because of the virus. After this video, I had it stripped down, cleaned out and back together in under 20 minutes. Thanks a ton!

The Hvac guy doing the cleaning had a simple articulate approach of explaining & great attitude thanks Home performance 👍

Thank you guys soooo so much. Our apartment has this unit... wasn't used all winter and today noticed a massive amounts of white mold in this unit. Wouldn't have been able to take it apart and give it the cleaning it needed without this video.

** If anyone is hearing a loud knocking noise with the unit turned on after maintenance**
It is likely that the blower piece hasnt been put on the shaft far enough. I had to completely pull the unit apart again. Just loosen the screw slightly and push the unit from the left into the shaft a little more.

I used this excellent video to clean my Mitsubishi MSZ-FE09. Garret Beneker knows what to say, and what not to say--no wasted time, and well produced. Even though my unit has additional sensors and bracketry, I was able to follow along and figure it out. The first one took a couple hours--I watched the video several times and followed it step-by-step, the next time I do it it'll be much faster!

Fantastic video from a pro to clean it the right way. I couldn't run this AC/Heat pump in my studio over the garage! It started to really bother my eyes and sinuses. I had no idea these units need regular cleaning for the mold (I've never cleaned the air handler in the attic in my whole house AC, and still no problems). Even still, I'm very happy with this unit which is the only heat and ac source for this space.

FH-series is the absolute pinnacle of split ductless heat pump design. I applaud your choice. It really is an excellent investment.

[danrosenthal]

great video, clear and easy to follow. Note that spraying the foam on the coils can dislodge lots of water. Also, using a toothbrush to really clean into the plastic groves on each surface helped me. There are a lot of places were mold can accumulate. I made sure to open extra windows and doors to improve the ventilation for the foam cleaner. I'd recommend gloves as well.

Just cleaned my minisplit, this video was amazing as it's the same model I have and made the job very easy! Thanks for posting!

I have had a 6k btu MSZ-FH06NA working in our tiny house for a year now and we started noticing that we could hear the fan and the air would blow inconsistently.

I followed the tutorial from this video and now it’s working like new again, quiet and a noticeable reduction in time to cool the tiny house.

In spite of cleaning the filters every 1-2 months, the blower fan was caked with build up. We have a dog and live in a rural setting so it seems like I’ll need to do this on an annual PM schedule.

Thank you!

Maybe a couple screw locations were not clear, but this is a great video for the homeowner or repairman. Thank you!

[afrodite]

Great video! Easy to understand and without the usual nonsense talking or annoying music. God job and thank you!

[mikepavao]

Awesome video! Short, down to business, informative and easy cleaning guide. Other videos got you buying cleaning kits and termite tenting then spraying down your ac unit lol. What a headache! You gave me hope for cleaning my 4 units in one weekend afternoon...THANK YOU!!
