HVAC tech for over 20 years and this is spot on. First time I’ve seen someone mention the thermistor as well as removing the negative post first. Great job.

[frankswitzer]

I just watched a video from another channel on this. Dude, your walkthroughs are the best out there. No bullshit fluff either.

[kurzhaarguy]

Great video: straight to the point, no wasted rambling, easy to understand process without burdening it with detail. Well done!

Future video suggestion. We have service line shut off valves throughout our homes. Why RVs have none remains a key head scratcher for me. I installed a simple in-line shut off valve when I replaced the broken (from freezing most likely - oops) flush valve on one of my RVs toilets. This was an easy DIY mod that not only made replacing the valve less messy, but also allows me to isolate/ stop water flow to this toilet when (unfortunately not if...) future repairs are needed. Over time, I intend to install in-line shut off valves on all of my water lines (other toilet, kitchen & bathroom sinks). I’d make this video myself, but time & good video equipment are limiting factors. Thanks for your straightforward, easy to follow presentation style. Much appreciated.

Absolutely informative and in layman's terms, atta boy. Only one constructive criticism about the evap coil"....so your coils don't freeze, expand, and rupture..."??? Gotta get more familiar with refrigerant, my friend. Heat, not cold, causes it to expand...that said, one of the best and most thorough videos I've seen. Good on you, sir. Blessings.

Nice Informative video. Nice Job! We have the same A/C. We just did a minor overhaul of ours (9 years old). You can use a can of air you use on computers and electronics to blow out all of the dust. Also a paint brush with soft bristles helps. While you are up there, wiggle your fan shaft forwards and backwards and spin it. It may need to be soon replaced if it is noisy or too much play in it (There are videos on this). Take a pic of the tag on the fan housing for future reference. Unscrew the two bolts holding the metal box you see. Remove the box and check the wiring. Also take a pic of the start capacitor for future reference. If you fan or compressor stops you might need a new one. And, take your inside cover housing completely off and retighten the bolts holding your whole unit down on your rv. Just some additional tips while you are at it. The above fan motor, start capacitor and the cover shroud can be found on Amazon and Ebay.

This is the 2nd video of your videos I’ve watched and it’s the simplest, most informative, and best video I’ve seen on this topic. Thanks for making this stuff easier for a newbie like me.

[anthonypaulmannion]

This is one of the best videos on how to clean an RV AC! Thanks.

[paulbenoit]

Best A/C maintenance video I've seen. Thanks and well done!

[baja]

Very useful video, thanks to you. I will be performing this task in a couple of weeks when camping season opens up here in 🇨🇦.

[ceciliapetrowsky]

This was the best, most comprehensive video I’ve watched on air conditioning cleaning. Thank you!

[ricktaylor]

Spot on with the cleaning! Did mine over the weekend and also I watched your video on the vent modification you did earlier. Well when I went to take out the inside filter it appears Gulf Stream did it for me! After taking everything apart and looking at their handy work they did a good job, , imagine that if you will. Anyhow you put out some good advice and as long as I’m standing upright I’ll be watching your programs. Makes me feel smart😂😂

[matthewdupuis]

Brotha you do some amazing videos. I’ve learned so so much from these videos. Thanks so much.

[keithjohnsonsr]

This video was the best, concise and understandable from start to finish! I really liked how you shared the type of spray to clean with. I am now a Subscriber and I approve this video!

[Handled]

Ross, good video and explanation. I have watch several of your videos and you always do a nice job balancing length of video, timing, and covering the material.

[ghostpepperrides]

Well done. I use pleated filters. I’m a HVACR Contractor. Was great to see the blower and other items cleaned.

Ross - this gets me thinking. I have a white powdery dust material coming out of my AC ceiling vents. Our unit is a 2021 Jayco Greyhawk 30z with dual Coleman-Mach AC units. Have you ever seen this? It is not construction debris or dust left over from the assembly process. I pulled the interior covers off and vacuumed them out, as well as sealed all the open areas into the ceiling with silver metal duct tape where needed (and it was needed). I also pulled off all 12 of the round ceiling vents and looked into them. There was some construction dust/material in them. I used a shop-vac to suck from the ceiling vents while running a leaf blower into the supply ducts to evacuate all of said debris. I then reassembled the entire system. The white powder dust snow came again after several days of using the AC units. Pulling down the interior covers again yielded a non-significant amount of this white powdery substance on these covers that were just cleaned days before - all while parked, i.e. no driving in between. I believe that this is aluminum oxide coming off of the evaporator coils after being used ( i.e. getting wet and then drying). Once dry, when the AC fans kick in, the snow comes out of the AC vents again. Thi si a significant amount and covers everything in the RV - including getting into food, drinks, etc. Not fun. Very annoying. I am wondering if you, or anyone seeing/reading this, or anyone you have talked to has seen this occur in their RVs. If so, did cleaning the coils fix the problem? Or are the coils defective from the factory and need to be replaced. This is such an annoying problem. Any insight?
