RV Air Conditioner Maintenance

[@spudbono5747]

You are my RV maintenance spirit animal. I just spent the day on the roof logging some quality time with my boyfriend, Mr. Dicor, and was looking at my A/C unit wondering what the heck I need to do to it. Certainly something, but what? My dad was an auto and aircraft mechanic and could build or fix anything. In fact, we grew up camping in a trailer he built from scratch. He has been gone 20 years, but I am convinced he works thru other mechanics to get messages to me on occasion!

[@LoveYourRV]

haha, cool!

[@RVwithTito]

Hey Ray. I use a weed pump sprayer to rinse the coils. Works pretty good especially where you don't have a hose. Great tips!

[@williampatten9165]

Ray, I must apologize for missing your comments concerning the motor soft starts, but as for your reply to my question,,,Oh that was brilliant! I missed that comment when I watched this video. I was really interested in the cleaning of the evaporator and guess I didn't pay close attention. Thanks Ray, you're the best!

[@LoveYourRV]

No problem, the link was actually to a newer video I did just last month on replacing the AC gasket www.loveyourrv.com/rv-air-conditioner-maintenance-new-gasket-seal-clean-lube/

[@DownsizingMakesCents]

Very thorough explanation of rv ac maintenance, most RVers do not maintain their ac system, they just wait for it to break down, or become less effective before it gets any attention. Ray had the right idea, being proactive and getting on the roof and doing a little ac maintenance once or twice a year.

[@papapistole7047]

Seriously, thank you so much for this channel. I've been living in a fifth wheel for years now and I've just been letting it fall apart.

Ray, if everyone took as good care of their RVs the shops would go out of business! You’ve taught me so much about the proper maintenance of an RV. I’ll be set when I get on the road.

[@bonniejohnson1518]

why do you want the shops to go out of business? Its not the shops fault that there is FOMO mania hype connected to RVing...The shops were created to fill in the void, many cannot do their own work, only partial repairs...

[@johngoold1218]

I love watching Ray's videos. He always teaches me something I need to check on my RV. Or fix! I've used his videos to replace my RV black and gray water tank valves as well as check my AC like he shows above.

[@lit2010ny]

I really enjoy your videos because of the clear, easy going directions, & steps you take. Your honesty and views toward different products you try is refreshing. There is way to much negativity on the KZbins these days, so its nice to see not only your great and helpful videos, but also to be able to read through the comments on other peoples experiences/tip & tricks. You have a great community following, I would not change a thing/keep em' coming! Thanks again, and hope you have a great camping season!

[@jimbertrand2499]

Oldie but goody Ray!!

[@thomaslevy2119]

One way to tell if your AC is healthy is to measure the amps it draws. I installed a permanent volt/amp meter in my 5th wheel because I am on a 20 amp circuit currently and do not want to overload the breaker. The AC normally draws a maximum of 15 amps on a hot day. Last summer it began pulling 17 amps. I found the coils clogged by dirt and leaves. Cleaned them and straightened the fins as you did and the AC went back to pulling 15 or less amps. Overheating the compressor will greatly shorten its life or even kill it. Good idea to check and clean the AC every spring before running it.

[@LoveYourRV]

Interesting tip. thanks. I have a surge protector with a voltage and amperage readout. I'll give it a look.

[@thomaslevy2119]

At my previous location there were no trees. I am now parked under a large tree. I didn't think about leaves getting into the AC. I do now!

[@sweetsingin]

I can’t tell you how grateful I am for this. Thank you so much!!!

But hey, not designed for this right. Will try your clean job to see if makes a difference. Cheers.

Yikes! That's way too hot! We are supposed to hit 90F here in Campbell River by next weekend and I thought that was hot. Normally it should be low 70s this time of year. But early June was mostly mid 50s so I guess it evens out. All the best, Ray

[@kathrynarnold1966]

@@LoveYourRV I finally realized there are screws under the three little ski-jump brackets at the bottom. The fiberglass insulation on the sheet metal part that is removed, where the edges met the main unit, must have stuck and is all tattered. Do I have to put a new strip of insulation all along the edges between the two? Or would sealing the edges with aluminum tape do?

[@LoveYourRV]

I assume that the insulation is there because this is where the interior air flows, so the area is insulated from the outside hot air for better cooling. How much of a difference it would make using just metal tape I'm not sure.

I had a thought, watching your video I was thinking maybe using a Shop-Vac to suck the foam out of the evaporator coil after it's absorbed into the dirt and released the the mud on the coil fins use the vacuum cleaner to suck the moisture out of the fins and not have the muddy mess inside the rig. NOTE, the chemical sprayed on the coils needs to be pretty harsh in order to break the oily film on the fins to be able to dissipate the heat from inside the rig. Makes it work more efficient.

I have to regularly use toothbrush bristles to force grease into the shaft bearing of the motor you refer to. The right thing to do is replace the motor. However I have just got into the routine of doing this about every two months. The motor lets me know if it needs it sooner by a certain noise from the slop of the worn bearing. I have been doing this for two years so I will continue to do so until it no longer works. Standard "high temp" grease will only last about a month but true high temp grease gives me a full 2 months. Used to be STP but I don't believe it is sold anymore under that brand. Coastal I believe now. Anyhow it had a temp rating of 550 instead of 400.

[@LoveYourRV]

I've heard that from a few folks that say they use it and it works well. I'm a little hesitant as I know that Simple Green can corrode aluminum if left on it too long. It's in the companies FAQs and I've heard stories of it eating aluminum wheels.

Good morning Ray! Beautiful weather this weekend. I received an email from Camper Report, and in there was an article about Boondocking. They mentioned a product called a SoftstartRV A/C starter.

[@marcgoldstone7844]

I live in and camp in the Mohave Desert which can be dusty! My coach has two Coleman Mach 10 Heat Pumps. While in COOL mode, I get an abnormally large amount of dust and dirt building up on the Evaporator coil necessitating cleaning the evaporator 3 or more times each year. I clean the units interior air filter every two weeks. I don’t have any water leaks into the coach from the AC so I know the main 14” square gasket is good. I believe the problem is that there isn’t a filter of other means to keep dirt from entering between the roof and the AC’s metal base plate at the two condensate drain holes. A piece of open cell foam inserted under the metal base plate and on top of the roof under the drain holes would prevent dirt from being sucked into the area under the evaporator shroud. This foam would allow condensate to drain through it to the roof but would stop dust from getting into the evaporator coil fins. Alternatively a small Duck Bill check valve inserted through the base plate evaporator drain holes would likely also work. I plan to clean teh evaporator coil tomorrow and will try a small piece of the open cell foam inserted under each of the drain holes. Time will tell if this makes a significant difference.

Why not a shop-vac with brush attachment to clean the condenser no??

[@LoveYourRV]

I was afraid it may be to aggressive and risk bending up the fragile coil fins.

[@geraldhenrickson7472]

Back in the day we used to always vacuum the fins to extract the debris and use a soft horsehair paint brush OR a fin straightener on the stubborn stuff. In school we were taught to never use a water spray as that forces the debris into the fins. Why does no one vacuum anymore?

[@LoveYourRV]

The fins on this evaporator are so thin that they bend really really easy and the older the unit gets the more brittle they become. The stuff on the evaporator fins was really glommed on there, wasn't going to sweep off. The condenser fins seemed much stronger.

[@mrfixit603]

I agree with a soaking and vacuum . As on a car radiator, if you must use a hose , you usually reverse flush from the way the dirt was introduce on the coil. In this case it was sucking in ,so it should be pushed back out the way it came in.

[@williamwatterson2499]

Great video. Keep up the good work.

[@greengrass89]

I just took my heat pumps off the roof, soak them with simple green and spray them down with a regular water hose. As long as you don’t spray sideways across the fins, they will be fine. Let everything air dry. Reinstall with new 14x14 gaskets and you’re done!

[@dogpatch75]

Don't underestimate the importance of checking to see how well your AC duct system is sealed. We found ours to be extremely leaky as a result of shoddy factory installation workmanship with gaps in duct insulation and the foil tape seals everywhere. Check not only your blower/return unit but also all of your duct taps and vent covers. A couple of hours of redoing joints with HVAC tape doubled the air flow from our vents. It turns out we were blowing a lot of air conditioned air into the void between our ceiling and roof! Ours is a Coleman TT which is one of the many brands owned by Thor. I would expect to find some shoddy workmanship somewhere in your RV regardless of your brand.

[@LoveYourRV]

Good tip, it was one of the first things I did when the rig was new, dropped all the vent covers and checked. Most looked good but a couple places needed more tape. Cheers, Ray

A wet/dry shop vac with a soft brush will do a great job of sucking out those coils as well as the squirrel cage fan,

[@bobdally1]

Hi Thanks for the Video ! Can you tell me why someone would put a "hard start" capacitor on their a/c , I am new at this , thank you !

[@LoveYourRV]

It helps the AC start a little more smoothly and with a lower initial current draw. When starting the AC units compressor needs to kick on and it can take a surge of amperage to do that. The hard start capacitor stores energy and can release it at the start-up stage, thus reducing the amperage draw from the power input to the RV. Why is that helpful? It can reduce the chances of blowing breakers when running the AC and multiple other devices in the rig, especially in hot weather. There is less strain on the AC parts helping lengthen life. Many people use them to help a generator start up the AC unit, where before the generator would go into shutdown mode not able to power the initial surge current needed to fire up the compressor. Some RV AC units already have a hard start capacitor and other don't. Another device that is often used but much more expensive is a soft starter. www.microair.net/products/easystart-364-3-ton-single-phase-soft-starter-for-air-conditioners Cheers, Ray
