I just wanted to take a min to thank you for accurately giving advice on ac. I work on ac’s and most people think if it’s running all day it’s overworking the unit (not true) and like always you were spot on. Most videos i watch people have no idea how ac’s work and they try to describe it and it dosent turn out well. I will add one thing if you like it set to 72 then set it for 72. Putting it at 60 dosent make it cool better or faster just makes it run longer. With ac’s there either on or off set it where you want it and let it work.

[@plz1277]

I wonder what you or Todd think about those of us that don’t need to run our AC often because of our location. Do you recommend occasional starting the AC up to grease the bearings and whatnot or is that not necessary? Thanks in advance for your input!

[@williamwells489]

Can I paint the black shroud white?

[@Starry_Night_Sky7455]

What if the AC is an inverter? That isn't an on or off compressor. It gradually adjusts while always on. Well that is what I have learned about them. 72 is still way too warm for me. 68 is my set point for room temperature (and make that humidity stay below 52%). But setting an AC at 72 can often bring about a 68° F result. No need to overwork the AC if you don't have to.

[@robertschulke1596]

Installing one of the duct streamliners, or making one, can improve airflow 40%. Cleaning ducts and filters is also essential. Shutting off unused areas can give better cooling where you are. Desert dwellers use magnets to put reflective insulating tarps on the sunny side of their rigs. Park north/south to minimize mid-day solar exposure. Awnings, especially on the sunny side, can help a lot. Clean your coils inside and outside. A little dust on them goes a long way to slowing heat transfer, overworking the unit, and causing icing.

[@NationalRVTrainingAcademy]

Great tips. Thanks for sharing.

[@chrisschiel6741]

You can also remove the ac cover and spray paint it white (for 5 bucks). I did that and it made a great difference.

Maybe you can advise for a window unit AC for a room in a house? I want something I can run when the outdoor temperature is below 60°F at night. Im not opening any windows. It's too humid outdoors, and I hate it. I hate every day until October. Summer is hot, humid, and loaded with bugs. So, this room stays warm without AC running. I have a Danby brand air conditioner that so far has been amazing. It matches the Midea U Shape Inverter AC. Nothing in the manual addresses my question. I had been warned forever as a kid from my dad that coils on a central AC can potentially frost freeze if the AC is run below 60°F. Well, there has to be an air conditioner I can capably run to cool an indoor room even if outside its in the 50s or even the 40s? This room will maintain 64 with a window open if outside temperature is 32 (yes, 32) before I put the window AC in (that is back in Winter, not now). Over Winter I left that window open all the time. This house has central AC. Ductwork was recently checked. Now that its 80 outside, this room just stays warmer than rest of house so, I added that window AC. With the window AC, this room is 68, yesss. There must be an AC that can run cool like I want? I set this Danby inverter AC at 70 and I get 68 as result 🙂 but outdoors its 78 to 82 so technically that's probably the outdoor ambient temperature this AC is perfectly designed for. But, how about if outdoor temperature drops to say, 55 at night, and I wish to keep running the AC set to 70 all night (which awesomely maintains the room at 68), will that freeze the compressor or damage the unit? Is there an AC I can get that runs fine and dandy if outside it's below 60? Ive heard of something called a "low ambient kit" whatever that does? I basically want this room 60 to 68 with humidity at or below 50% from now to October.

[@hammer-r]

Do you have any experience on soft starts? Does this help or hurt the longevity of the AC unit? Many tks. Great videos.

[@NationalRVTrainingAcademy]

Soft starts generally help your AC's. Check out our videos on Soft starts. kzbin.info/www/bejne/aaDUmGeVYp2VrtU MicroAir also has a double warranty. kzbin.info/www/bejne/b2Opk2yEmKabla8

@@NationalRVTrainingAcademy cool and Tks. It’s not that we need our AC much when we are in Colorado, but I’d like the option and to use the Honda generator we have. I just wanted to make sure it wouldn’t damage it now that we are out of warranty. Everything else runs off of our 800 watt panel array and the two lithium storage batteries. Many thanks.

I wish the RV Aircon would kick the condensate up from the evaporator over the condenser to cool it and keep the water from running off the roof. My roof top works but when it goes out I'm buying a mini split.

Get a cover built over it so it doesn't leak best thing you can do

[@ThePackDad]

Why am I getting wet droplets hanging from ceiling vents? In VA, humid at 89° in July. AC on high at 71-75° and we get the droplets. I run a dehumidifier inside non stop. Bath vent open, blowing out with upgraded\sealed fan. No other vents\windows\doors open. Thanks for the great videos !

[@bajabugnut]

I would say running your bath vent is pulling in the outside air/moisture from where ever. just my 2 cent. Enjoy...

[@NationalRVTrainingAcademy]

Are these the vents on your AC or your manual vents?

[@RC-hm9vg]

Question: Since we don't want to have issues with it freezing, you said "run the fan on high". Would choosing "Auto" for the fan function be ok or would it never run the fan on high in auto function?

[@NationalRVTrainingAcademy]

Best practice, when you are running your air conditioner, leave it in High. Air flow is key.

[@AndrewMcSpadden]

Can you do a video on improving airflow? A/c and furnace ducts?

[@NationalRVTrainingAcademy]

Sounds good. We will get on it

[@murdoc4072]

I second this. My FR ducts are rectangular 1/2” low density (styrofoam) with 90° corners. Extremely inefficient for air flow. I won’t even get into the poor foil tape job and air leaking into the ceiling…😒

[@RC-hm9vg]

Look at “RV AIRFLOW SYSTEMS”. It’s an in-line piece that increases flow.

[@mikewarren4397]

Great video sir.. question - I have 2006 NUWA ducted AC - 15,000 Mack Coleman.. full timers. In Arkansas high humidity.. do I need to run fan speed on high all day and all night or just at night ? .. thank u

[@NationalRVTrainingAcademy]

Auto is fine. It when people take it off auto and put it on low where the potential problem exist

[@poole425]

What's your opinion on running the a/c fan on high 24/7, and just letting the compressor cycle on and off as needed? We have 3 a/c units, and the one in the bedroom seems to run a lot no matter what temperature I keep it set at, and we've had problems with it freezing up. I keep the fan on high to prevent this, but when I do the fan runs 24/7 (it doesn't cycle on and off with the compressor). We live in our RV full-time half of the year, so this isn't just an occasional thing, and I wasn't sure if that would negatively affect the lifespan of the a/c unit. (Note: all a/c units have white shrouds already).

[@kevinbarrow9950]

I'm new to RV's and have heard different opinions for when using reflectix or other reflective insulation in my windows. It seemed to help keep the RV cooler, but will it or can it cause damage to the windows or window seals?

Using command strips won't damage the windows or surfaces you decide to put reflectix on.

[@NationalRVTrainingAcademy]

You need to run it on AC High. Or Auto High. When you run it on Fan you aren't using the AC, just the fan to blow air around.

[@johnhines3591]

When we need AC, we allways have fan on high. The noise level is basically no different from high to low. We don't have ducted AC. Since low fan can contribute to icing issues, why do they even have a low fan speed ?

[@NationalRVTrainingAcademy]

That's the age old question. There's really no purpose for it. Maybe if you run it just on fan. but that's just blowing air.

[@kennethgahley134]

Would it be advisable to have soft start installed to help with the hard start.

[@NationalRVTrainingAcademy]

absolutely. That lessens the initial Amp Draw which helps your power systems.

[@johntatman9168]

Great info. If the unit is literally running all the time you might want to consider a larger unit or more insulation.

[@Studiovette]

You can actually do harm by having an oversized unit as well. It will not cycle properly and thus humidity will be more likely to build up since the larger unit will not work as hard to cool the area. It will shut off a lot quicker. I learned this from my HVAC guy. Lol.

[@NationalRVTrainingAcademy]

Pete is correct. You want to Keep your AC's at the correct size rating. There are lots of ways to increase the efficiency of your current unit.

Hey Todd, there was post that claimed running your A/C compressor all the time (CONTINUOUSLY) was not a good thing to do?? Why was that post DELETED? If you don’t agree with that guys response, why wouldn’t you just explain why instead of deleting a reply that was the opposite of yours???

[@NationalRVTrainingAcademy]

The response was not appropriate to discourse. Disagreements and questions are welcome if done without twisting of words. You cannot run the compressor continuously unless you override the circuit board. The takeaway is for the non tech to understand they can set their desired temp in the thermostat and not worry about damaging the AC. The high temp limit switch, freeze stat and logic in the thermostat will cycle the compressor as needed. The understanding is run your ac as it’s intended.

[@mikezimmerman1247]

@@NationalRVTrainingAcademy Todd clearly said “the fan motor and compressor are continuous duty, so yes, you can run them all the time” So NRVTA is standing by this statement??

Do you think there is my difference running a dehumidifier full time or the AC when it comes to cost. I have a medium sized home dehumidifier running now.

[@NationalRVTrainingAcademy]

Running the dehumidifier really just needs to be for humidity control. Unless you live in Florida. The goal is to ease the coils in their cooling process as they don't have to strip as much moisture out of the air to cool it down. Thanks for sharing.
