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.
Awesome praise, thanks so much!
Yes, this is the clearest, most comprehensive video. All the steps are there. So grateful!
Happy it helped you Maya
I’ve been an HVAC technician for 25 years and to this day mini splits still scare the s**t out of me because I’m always convinced I’m going to break something. This is one of the absolute best videos I’ve ever seen on how to service these units. Well done sir!
Wow, what a great comment! Thanks Christian.
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.
Purchased: August 2023 - still works GREAT!I ruclips.net/user/postUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install. This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment. I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!
Huh? Where do you have the drain pan draining to? Water condenses on cold AC coils and the drain pain will fill with water.
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.
Great to hear we helped you, Kirk! That’s why we do this!
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.
Wonderful! Glad to have helped!
You actually explained that in more detail than anyone else thanks mate from Australia
Happy to hear- glad you found us bud
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!
Dude. Great story. So glad you found us.
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.
You are SO WELCOME. Grace and I love hearing that our vids help people like you!
By knocking noise do you mean like a helicopter?
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!
Hell yeah my friend!
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!
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 !
THANK YOU SIR
The Hvac guy doing the cleaning had a simple articulate approach of explaining & great attitude thanks Home performance 👍
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!
High praise, thanks for following
FH-series is the absolute pinnacle of split ductless heat pump design. I applaud your choice. It really is an excellent investment.
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.
Great advice all the way, Dan. Thanks!
Great video for the FH Series mini-splits. I thought I would add a couple of details about the removal of the plastic housing for clarity. There are 5 screws in total, two are under an easily removed angular cap on the lower lip, two more on the right and one on the left, all shown in the video. The large cover pops right out when open and is easy to put back on, the right hand plastic housing is pretty easy too. The large main housing needs to be pulled out from the bottom a bit, especially on the left side, and then a pretty forceful pull from the top. There are four plastic clips that you pull straight out from the wall. I found starting from the right, then middle and finally left worked best (I have three units, so I got better at this). Putting it back is easy...line it up and give the top front in line with the clips a slight punch with your palm, working your way down. Finally, there is a strip of plastic on the bottom edge that must be removed. I had trouble with this, but it turns out there is only one clip in the middle that you need to pry with a flat headed screw driver to get it to release. That was not obvious in the video, although they do show it being removed.
Good tips, thx
Excellent video, and super generous of the HVAC guy to share his knowledge.
Despite emitting a musty odor, my unit didn't initially seem that dirty. No streaks of dust on the blower wheel, and none of that black mildew anywhere inside. However, when cleaning the blower wheel, I found that a thorough outdoor rinsing with a garden hose (even at full blast) insufficient for removing the thin film of unknown substance collected on the undersides of the blower wheel fins. In the end, I had to manually scrub every fin individually with cotton q-tips - a very laborious process! Based on my experience, I would recommend anyone trying this themselves to spend the extra time needed to be a bit more meticulous with the blower wheel cleaning step.
Try using soap water next time instead of a q-tip!!!
Thank u
What about spraying it down with lemon scented Lysol, in addition to the soapy water?
I used kitchen degreaser diluted with water and a shoe polish brush, wheel like new
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.
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!
🙌🏽
Just started service this summer. About to do my first deep clean on a Mini Split this week. Thank you for this video!
Maybe a couple screw locations were not clear, but this is a great video for the homeowner or repairman. Thank you!
So glad it helps!
thanks so much guys.....tore mine down and cleaned today for the 1st time, had it almost a year.........oh my gawd!!! Surprised we are all not trying to eat each others brains! Back up and running, made a huge difference. I thought it was dying, turns out, was just filthy
thank again!!!
Glad to hear it!
I have cleaned my unit each year, but never took the blower fan out. It was So much easier and did a much, much better job now that you showed me how to do the job right. Thank you!
Great to hear!
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!!
✊
One of the air handlers in my house had started rattling and the airflow seemed less than it had been. I have the exact model as the one in your video, and the video enabled me to take everything apart, clean and reassemble. It only cost me an $8 can of ac coil cleaner. It is working great now! Thanks for the informative easy to follow video!
HELL YEAH JUNICAT
Great video! Easy to understand and without the usual nonsense talking or annoying music. God job and thank you!
Thank you!
After numerous videos, yours was the one to help me get the outer cover off. Thanks for the detailed video and saving me $$$!
You’re very welcome, Todd! Glad you found us!
Just went through this exact procedure today with the help of this video. Had to pressure wash out the blower wheel, but now it looks like new! Thanks for this video!
So glad it helped you, John. I rewatch it every time I have to do it myself!
Great vid. Used it today to save a great deal of $ on my cleaning. First cleaning since install 2 years ago. Now I am confident enough to do this every 6 months or so. Wife is black mold toxic.
Got any advice on the rotating electric eye noise. Kind of a clicking sound.
Super helpful! Thank you for the great video. I was able to clean my unit myself because of your work.
That’s the dream my man
Thank you for posting this tutorial. It helped me with cleaning my units.
The only thing I would add is that the drain pan is alot easier to reinstall if the coil mount screws are still loose on the left side of the unit. Once in place then tighten the mount screws. Regardless, very useful video. Thank you.
Wonderful, glad it helped.
glad I found this video. I already knew how the right side came apart (cn105 access) but not the entire unit and the little wiggle tricks needed.
Man did my oldest sons u it have mold. Took 3hrs to clean all the mold and that blower was caked with dust and mold. nasty!!! seems the air filters are not adequate enough. will need to clean this yearly going forwards.
As was stated by someone else, my blower was rubbing somewhere really bad, had to push all the way right. now it rubs less, maybe I moved it too far right. next time I pull it apart I'll have to adjust it again. .. again thanks for the great video.
Thanks for the run through. With the help of this a got mine spotless ( first deep clean since install 6 years ago )
NICE
From my experience at the Mitsubishi diamond dealer training center in Boston i was informed to never use anything but water to clean the coil because coil cleaners will strip the protective coating off the fins resulting in faster build up. I would prefer to use an actual cleaner over water. What are your thoughts?
I have the actual service manual for this, but that did not help one bit in taking the unit apart. This video however, was exactly what was needed to quickly take the whole thing apart, including the cylindrical fan. Thank you.
I know, right? That’s why we got Mitsubishi involved in the making of the vid- they hadn’t solidified a protocol before then.
just finished cleaning of mine after 5 years of usage, thanks for the video guys, did help
Great to hear- cheers
My new heroes..I followed the video exactly and saved myself a big bill. Thank you so much. Two more to go....lol.
GOOOOOO CRYSTAL
I have watched many RUclips videos on this subject and this by far the easiest to follow and understand!
Millions of microscopic spores are floating in the air as he is wiping the “mildew” from the drain pan. We see HVAC techs normalize mold constantly. I can see why. That drain pan should have been cleaned outside. But thank you for this video! I learn so much from your vids. Almost every time I’m looking up something to do with IAQ or home performance, I’m brought here :)
Man these guys are trained to not sat mold smh
Thanks Pete! And don’t feel too hard on these guys- they’re not trained or equipped to do many of the things we explore on this channel, and they run from hot attic to nasty crawlspace all day. One of the most terrible jobs I can imagine, frankly.
@@HomePerformance 100% agreed! These guys see the worst of the worst daily. We need to change the standards of building and stop building vented dirt crawl spaces and unconditioned attics! Not to mention, placing HVAC installs in them, duh! Ultimately though, humans need to stop neglecting their homes…
Thank you! This gave me the confidence to clean it myself. Great instructions, marvelous engineering.
Happy to help Paul
Great video! Have installed many of these units but never needed to do a maintenance till I put one in my own house!
HAHA nice
Mildew also comes from not running these in Fan mode, after using as A/C, to give it time to dry, before turning it off.
Not mentioned, many health hazard warnings, on the evap cleaner foams: googles, gloves and high ventilation turnover needed when using these.
Well explained video. My Mitsubishi H2 unit was full of mold, by following this video I was able to disassemble, clean and reassemble the unit.
This was extremely helpful. I have 4 units. No issues during the process but I chose to rinse the cleaner off the coils with a garden pump thingamajig. They didnt think about it during install to cover the drain pipes on the outside with a grate or anything. Had about 6 carpenter bees in each drain pan. Dead at least.
Yuck! Nice catch!
This is EXACTLY what I needed! I watched many videos that I was unhappy with before I stumbled upon yours. Thank you!
EXCELLENT to hear, Jayme!
John Thank you, very informative. I currently have a problem with the flappers. They won't open at all with the machine running.
could you please advise what the problem may be.
You should refer to your manual for troubleshooting and then hire a Mitsubishi diamond contractor.
This one video saves me $800 a year. Thank you
Wow! Thank you so much for this. I have had mini splits for about 3 1/2 years. I pay to have maintenance done twice a year. A leak has recently developed in the front of one of the units and I can see mildew in the back of both units. I have never seen them do this sort of maintenance on the air handlers. All they do is clean the air filters 😳 I thought it was strange they weren't doing these types of things. Thank you so much!! I will be in touch with my HVAC company to make them aware of what they ought to be doing with their maintenance routine.
Glad you found us, and good luck
@@HomePerformance Well, didn't have much luck in convincing them they should be doing the sort of maintenance. I got details on what they consider "maintenance". All it is is a look see inspection to how things are going. If you need anything done of the nature you guys were doing in this video, they will charge you to do it.
Same EXACT situation with us. Paid $400 for them to clean the air filters on 7 units. That's just insane. I called them and asked them why they don't do this level of service. They said, "We'll have our front desk schedule service." Nope. We'll do it ourselves now with this great info and it will be done right. Is there much difference with the MSZ models?
Should be about the same process, Debra- keep it up!
That’s wild because cleaning the air filters takes like 2 minutes and any able bodied person could easily do it
This is the best heat pump maintenance video I've ever seen precise detail well done👏👏
Thanku..
👍🏽👍🏽👍🏽
Just took my M series apart to clean and adjust a noisy blower wheel. This video was super helpful. Thank!
So glad to hear! Congrats!
I have 3 of these exact units and was able to thoroughly clean them thanks to this video. I really appreciate it!
Wonderful, good work
It is the best video that I have seen so far, thanks for sharing.
So glad it helped you!
Excellent video! Great walk-through of how to clean these units!
Thanks Doug!
I’ve got 4 FH units.... I blow them out with compressed air every 2 months and spray coil cleaner after every Summer.
I used your vid to irradiate the awful alpine condensate pump. Thank you!
Thank you this helped a great deal And now my AC is cool and the unit is blowing much harder.
Wonderful! Stay fit, Dad.
This was super helpful! We had our unit in an attic that didn't see much action before, so we hadn't cleaned it more than washing the filters over the last five years. We've used the room as an office and now a hobby room, so a lot more dust has kicked up and a cat roams around, so I finally gave it a good cleaning. It would have taken way longer without this help!
Happy to help, Tom- thanks for sharing
Thanks so much for this great tutorial! I followed along while cleaning my FH and everything was pretty much as seen. The only thing I ran into is that I had to pop off two little caps to reveal the bottom screws. I initially didn't notice the caps until I started getting the thing taken apart because they look like part of the housing. Fortunately ours didn't have any mold, however and unbeknownst to us, there was a bunch of blown in cellulose insulation that had come through where the hoses and cables pass through the wall and it filled all the spaces around i-See sensor servo.
Glad it helped
Video was super informative. The most important information I learned was that I would never have anything that needed that much maintenance in my home. What a user unfriendly design.
My air handler is 29 y/o. My filter is a Honeywell electronic air cleaner. I get no smell and I have never cleaned the evaporator coil.
It is not very easy to clean. But for once every maybe two years, it’s not too bad. It’s also exceptionally efficient, installed easily on my house which has hot water heat and therefore no ducts whatsoever. Each room has its own thermostat. Once it’s cleaned I know it’s completely clean. That said I wish it didn’t have so many plastic nooks and crannies to clean. But tbh it’s worth the advantages of the system. Mine never smelled, even though there was some buildup of gunk. I’d be scared to see what 29 years of no cleaning looks like, have you ever looked inside there?
Great video, cleaned mine in 1 hour following this video, thanks :)
You’re welcome Zoran! Glad you found us.
HVAC is what I do for a living and I would like to relieve my customers of this grief of having to go through this cleaning process due to mold mildew funguses that grow in different areas of the country that are more or less prevalent in different regions. This is why I install the RGF mini on all my small residential condensing heads to reduce or eliminate molds and fungus growth. The RGF unit creates a peroxide molecule that stir lyses the evaporator coil and drain pan and fan blades that developed a mildew that grow on their surface. Some contractors may argue that I'm giving service away and I'm making less money by not having the customer call me back for a few hundred dollars to clean out their air handler. But I happy customer with fewer maintenance callbacks will be your best advertisement, if they know you have their best interest to save them money and not just thinking about your own pocket and trying to pocket their money into your wallet.
+t lech great solution! thx!
When a customer delves too deep and screws up, guess who needs to come save the day?? Soo many people overstep themselves and expect techs to come immediately to remedy their self-imposed screw-up!!! CALL a tech!!
+Atom Atom quite true, but what if there are no local techs who will perform? What if there are, but they don't call you back?
I cleaned 2 and everything came out fine. Another units blower wheel looked clean and no mold was visible so i just sprayed the coil and let the condensate run out the drain pan.
How about adding an additional layer of filter material on top of the air handler? Will that help cut down the dirt on the blower?
Great video.. thanks for the info! I'm going to be trying to clean my unit this afternoon! Wish me luck! :)
Good luck buddy! Be patient and give yourself room!
Great video gents. You saved this retiree a little money.
I wish I had known about this when I had my unit installed 4 years ago. Now I'm sure I'll have quite a bit of cleaning to do and hope I can remember most of the instructions shown
Don’t have to remember, just come back and watch anytime
Thank you for this video! I have the same model, so disassemble and cleaning was exactly the same. Was afraid of breaking the plastic clips, but came apart without issue. Have to wait till the summer to clean the coils like you did with the cleaner. Thx again.
They break, now what?
Just cleaned 9 of these. replacing the wheel on the larger units can be a nightmare. try placing the wheel centered on the shaft (maybe add some lithium lube) and push to the right while spinning until it snaps in. Can take a lot of trial and error.
Thank you!!! You have the best demo videos I could find + the best music. 🙂
Great Video! Thorough and easy to follow,
Helped me confirm an issue with my minisplit and identify another- it doesn't have a removable drain pan or any visible way to service the blower.
Damn
I have good results with mini uv lights really keep the mildew away. This is a problem in all mini splits even when they are installed correctly
Joe Shearer if you have uv resistant plastics than ok
That was what I was wondering. That and also do the lights make it more difficult to take the blower wheel out as it'll still need to be cleaned.
Interesting idea. Be aware though that the Mitsubishi Manuals have a trouble shooting entry for yellowing of plastics. The cause is exposure to UV light...
Thanks for the video! I have this exact same model and used it as a guide to do mine this afternoon
Always great to hear!
Do you have the FH series like the video? I did one of mine yesterday and was surprised to see rust on the right side of the coil. Also after reassembly the upper horizontal vanes don't seem to close as flush as the units I haven't taken apart yet.
yeah I do. Mine had some rust on the right side as well.. I think that's common on ductless as most of the videos I've seen have that. As for the vanes, it's not supposed to matter what position you put them back in as they should do a full sweep at startup to orient themselves
@@Cryptic-1-9-1-1
Mine do the full sweep and operate correctly, I just noticed the top vanes aren't fully closed and parallel with the front cover like the one in my son's room which hasn't been apart. I double checked and they're in right, not a big deal just being a bit particular I guess. I think the rust is normal there as well, they should have used stainless steel IMO.
Yeah I wish it was all stainless as well, but it's probably not nearly as good at heat transfer as copper and aluminum.. plus the cost :(
Sooo glad I ran into this video. My mini-split looks horrible. I thought the only thing I needed to clean was the filter. Also, your friend in all black looks like he ain't the one to play with. Like, on ANY given day, LOL.
Glad you found us too!
clear and thorough presentation
Thx
Thanks!!! The SET SCREW!! I spent hours alternating between watching videos made by wingnuts who just wanted to sell their cleaning kit, and inhaling probable Legionella spores into my bronchioles while trying to figure it out myself before I finally found this video (cough . . .).
So glad you found us brother
@@HomePerformance Has it really been 3 years?! I guess I oughta clean it again. . . and I'm taking this vid with me. Thanks again.
Illustrates how poorly these air handlers are designed. It's analogous to removing a car engine to change the air filter. But the car engine filter will not blow all kinds of mold spores around. The minisplit (and all air handlers) bower fan should snap out for monthly cleanings like the filter!
You'll love this then:

Awesome video. Thank you very much!

Beautifull job, Thanks

Thansk a lot, very good and instructive clip! Helped me to clean my own.
Now , I need a video on how to level the unit!
I did it! I was getting virtually no airflow down the entire center 80% of the unit. Nobody instructed us on routine maintenance beyond cleaning the filter every now and then so you can imagine what the fan looked like after maybe 8 years 😅
I was a little worried because it is hard to tell how much force you're applying in the video. Especially around the coil assembly I feared I might break the whole thing in the middle of summer.
Some steps require a little more than a gentle nudge but I was able to get it all cleaned and reassembled with no broken pieces and it's working like the first day again.
One thing I noticed is that it seems like it's starting to build a bit of corrosion around the right side of the unit near the drip pan around the copper coolant pipes. Like the coil fins are a bit discolored in a copper tone and there was the same color residue in the very right side of the drip pan. Is there anything that can be done about this or is this even something I gotta worry about? As long as it's not damaging the pipes and only discoloring the surroundings it's no issue but if the seal breaks it's probably a goner.
Good work buddy- don’t worry about the discoloration, mine look like that too after only 3-4 yrs.
This helped clean my unit! Thank you!
Glad to help, cheers
Thank you so much for rhe tutorial/video. Indeed one of the best video/tutorial/thos is how to do it I've seen. Been having issues with water dripping and with our Hospital maintenance crews busy elsewhere I'm glad I can do this and help them out. Will be passing this to our other crew members so they can also take care of the units in their rooms. Thanks again
One last thing.... any other alternative coil cleaning that can be purchased/used by us general public? If there is, can you update us? Thank you
Interesting, Juan, and happy to help! Quick search of Amazon for ‘A/C coil cleaner’ four stars and above shows 179 results. Have fun- with that much practice, your crew will be stellar.
Nice video. I have the same unit. Two questions: (the unit is 8 years old). I have dirt coming out of the unit every or every other day, dirt in the form of black/grey chunks that look like compressed dust. Could I take my leaf blower and blow through the unit to get the dirt/dust out? Could that ruin the unit? Thanks, david from Toronto
That is probably mold. I would guess when you remove the wheel it will be full of mold.
The Mitsubishi rep should have provided a website for written instructions on this procedure.
Thank you for the excellent video. My unit has been dripping water, with the drain pan overflowing. Do you have any tips / suggestions on cleaning / clearing the drain line from the unit? The rest of the unit seems clean.

Excellent video guys! Really best one out there - very clear and helpful!
+George Mandler thx for watching and complimenting!
We were never told about the fact that this unit needs to be cleaned. The instruction booklet only mentions cleaning the filters which we do but later found the inside was filthy"
+CD Rozich I know, right!?! What is wrong with the writers of user manuals everywhere?
@@HomePerformance Who knew Mitshubishi does not make a TOTALLY maintenance free hvac?
FYI.. My five winters and going into the fifth summer is a 45% reduction in heat bill and 35% in summer cooling cost. The real story is my home no longer has issues with mildew or mold.
😎
Thank you for a good simple video. Would you consider posting a similar video without any music in the background? I would like to more easily hear what you are saying without music that detracts from what you are demonstrating.
Great video! (HVAC-guy seal of approval)
+Neil Comparetto 😎
So... this video inspired me to clean my 2.5 y/o Daikin. Let's just say it's nowhere near as maintenance friendly as the Mitsubishi. 1 down, 3 to go.
+Neil Comparetto keep rockin it man
I’ve done this service on my indoor head 4-5 times now, with your instructional video. But there’s something missing. What about the bank of coils in the back that faces the wall. How do you clean them effectively with the limited space due to the ceiling. Been using Viper coil cleaner but hasn’t effectively cleaned all the coils, this time around.
Wait, we're not just supposed to throw them away every few years like everything else? ;) Great stuff guys, keep it up!
Ha, Thanks P
Thanks for the quick response. For inside unit should I let sit...for how long? then spray water on it, then run it on heat?
For outside the fins are green with algae, should I use same cleaner, and then rinse? I do regularly blow around, under and in it.
What about the water dripping under it is that normal?
I've seen other vids for other kinds of outdoor units where they take the top off and spray foam cleaner in... none for Mitsubishi. wonder if that would be a good idea or if it would void warranty.
Had no idea this would be such a costly maintenance when I got rid of my wood burning stove and put it in.
Yeah, everything needs maintenance- better this way than sweeping a chimney though! Yes, dripping water is normal, that’s the condensate from the humidity being pulled out from indoors (I’m guessing). No advice for the outdoor coil, I’d ask Stephen Rardon (search youtube for his channel).
Totally hate mind so much trouble to clean I’m not a service person so un healthy system
Thank so much for this video. Got some installed a month ago.
Off topic, do you think 811kWh extra for one month (27.97 kWh a day) to run 12000 and a 9000 head sound like a lot average temperature was 1C the coldest it got was -9C and 11c during the day. Good insulation in my house, had home inspectorcome for rebate for heat pump and insulation and windows. Heated my house to 18c. I have the cold climate system. As I'm in ontario. I had to have the remote set at 22C to even achieve 18c on the negative days. But on the days where it was above 0 it got up to 20c or 21c.
Just wondering if i have a refrigerant problem. My tech guy says well it blows out warm air so it is fine.
Thank again!!!! Love you video. Learning so much.
They get installed and then it feels like I'm all on my own. So got to do my own research. And your channel is my favorites for learning about split heat pumps.
They don’t sell them everywhere and mold and mildew can grow anywhere doesn’t matter if it’s level upside down right side up specially in Florida it can grow five days after you clean it
LMAO
Great video. I was just about to call to have mine serviced. The outside unit has been leaking water at the bottom and is green on the fins. It was installed on a plastic platform on an unstable surface and is not level at all...by a diamond certified company BTW. They won't make good on it, and come out and get it level.
Do you have a video about cleaning the outside unit? Or can you explain to me how to do it?
Also it is winter here and quite cold can I spray the cleaner on the fins on the inside unit and just close it up or do I need to rinse it off. I mainly use it for heat, not for air conditioning. Do I have to wait till the summer to spray the coils like you did with the foam cleaner. Thx again, Viki
Hi Viki- just make sure to brush away all leaves from the backside of the condenser, and spray it down to get dust off the coil. Inside, yes, the stuff is meant to be washed off, either by automatic condensation or by you.
Can tell Mitsubishi too lol
Is there a drain hose on the right side of the unit that can be blown out as well? I saw the drain pan, not sure if I missed you covering the hose? My mini-split is leaking, and I'm guessing the hose for which the water drains could be clogged?
Haven’t tried blowing out, I’d use a pipe cleaner and drain pan tabs
I just watched this video and learned a few things. I have a 4 unit split system like this. Of the 4 units, only 1 (In our bedroom) constantly smells like mold and mildew only in the summer time since we are using the AC. I have cleaned the filters many times. I have made sure the system is draining outside. I have now just checked the level. What I have learned by watching this video is where mold and mildew can be in this unit. I just now shut it down while on dehumidifying since that lowers the smell and the coils are wet and cold. I will be tearing this apart thanks to your instructional video. *FYI this unit is a year and a half old and last year this smell started after being installed for 4 months. ANy additional advice while I do this teardown?
+Paul Andrew so glad it helped! Just take your time and keep all the screws safe. You'll feel so accomplished!
last time i cleaned mine an ac guy told me i can use dawn dish soap diluted 1to20 mix in a spray bottle to clean the coil in instead of coil cleaner, it works but its a mess. just fill a clean spray bottle with water and add 1 tablespoon dawn.
Thank you so much for your video. It helped me out for sure.
Happy to hear it, Michael!
