AC performance poll

[need-a-vacation]

15K a/c, so far has kept the 32 BHDS cool enough here in Mi. And we have had some hot, muggy days this summer.

Will vote for 15K, but like Mike wish there was a "So far so good for where we live" choice.

Its probably your 'where applicable' part. I would have selected it, but in my Greyhawk a second unit wasn't applicable. I would have absolutely gone 50 amp, second AC if it was an option. Hence, for me its 'not applicable' however I wish I had one.

we have the 212QBW TT, the 15k unit works well here in South Carolina. We have only had the TT a few weeks now but seems great. Only complaint is it is loud, but it is a small TT.

We have 2 A/C units - they work well keeping the trailer comfortable.
Only use both units at the same time when temps are very high or initial cool down after arrival.

My only complaint has been the noise from the 2nd A/C unit - it's a Mach 8 13.5BTU Front Bedroom A/C unit.
Sounds like a jet engine when running.

Just received and installed a Fan Blade replacement kit from Coleman-Mach.
Initial test in the driveway, the kit seemed to lower the noise level significantly.
We'll see on our next trip.

For others experiencing similar noise issues from their Mach 8 A/C unit, the Coleman-Mach's Fan Blade replacement kit is Item #: 1472D5041.
Coleman-Mach was nice enough to provide us with it under warranty even though we've had our trailer for a little over 2 years and was out of the warranty period.

There's also a Mach 8 Hush Kit on the market that can be purchased and installed that is supposed to significantly reduce the noise.

That is what I did, in fact I told the dealer I wanted and AC added before I picked it up.

Having lived out in Scottsdale/Phoenix which is in the Northern Sonoran Desert I know HOT, temps in the 120's are not rare and few AC's can keep up under those conditions.


Crabman, I see you live on the Eastern Shore, so did I for about 9 years, I lived where the mouth of the James River, the Chesapeake Bay and the Atlantic Ocean all came together, 16 ft sea wall in front of my house, loved it and certainly hated to leave, but Texas boy had to come home...

That would be what we here call "across the bay''. I live on the north side of the Chesapeake Bay Bridge Tunnel, much quieter then the Hampton Roads area.

Bumped up for this nationwide heatwave which is really testing the AC units.

[Kim Gass]

Hard to tell. Rarely use it. Temps don't go over 83
Usually in the 60s and 70's

[Marcm157]

Just got back from 3 days in a campground where I was in direct sun with no shade with temps in the high 90's and brutal humidity and I have to say I was VERY impressed with my AC performance...

3) It blows a lot of cold air, but sometimes not quite enough.
4) It is too darn loud.

I also have the same results.

15k a/c with thermal package

[schiguy]

Went out this past weekend with a high of 98 and heat index of 105 high humidity. We got a site with one tall skinny tree that cast a shadow up until about 9 am and then nothing for the rest of the day. When we first set up and turned on the AC's it was 96 inside temp on the thermostats both front and back. It took a good 2 hours to get the temp down to the set 72 degrees. The next 2 days the AC's kept the FW at a constant set 72 degrees. I was pretty happy with the performance of the units.

[Nighthawk 96]

We generally do not camp when it is hot. Have been in a state park when it was 95; problem was the voltage tended to get low in the park when everyone was using their ac. We have a 15k unit and a digit thermostat so temp stays at 74 for us.

Crabman I think it would be of interest to know what type of insulation package the voters had. Artic etc. that should have an influence on the performance of their individual units.
For me our 15000 unit works great but the analogy thermostat is the pits.

[bwalton]

Yesterday we had near 90 degrees and 70+% humidity. I had both ACs set to 72 but when I opened the door it felt like you could have hung meat in there. I had to turn one off and the other up. I think we'll be fine.

[Bookemdanno]

Just checking back in with an update. We have been in panhandle of FL since Monday. Highs have been in the 99's with at least 95% humidity! I've had both ac's running, set at 72. Way to cold...I've had to bump it to 75 to keep everyone from complaining how cold it is. I like it cold, but I'm outnumbered 3 to 1!

Whoops, put this in the wrong ac thread.

[My garage]

Have 2 15000 units spent winter in az temp 87 out cannot get below 85 inside used temp gun shot inside walls many reading 120 so where is insulation . Yes many read about 87 ,areas around outside vents and Windows also no insulation take out trim and look ,hot or cold air races in step area vents as it lets outside air blow in

[Mangort1900]

We had one 15K unit in a 2016 Jayco model 291 RSTS and we live in south eastern Washington State and we had to add the second 13K unit to bedroom. To get the rv to a respectable 70s temp . Should have bought with two ac to start with, we were surprised as our old Cardinal had one 13.5 K unit and it cooled 26 ft very well no issues ,20 yrs old ! I have recently discovered that if I turn the Base 15K unit on a higher temp and let the unit catch up,and then keep working it down with the thermostat after the unit has turned off by itself it seems to do a better job of cooling. I am thinking it was working to hard when I Would just turn to 75 .I think is was icing up and reducing affective cooling ? Had I known that I may have gotten by with one ac . But with 2 units. Just dial up,and cool. Good choice for us .

[Boudreaux]

Our experience in Roswell, NM (temps of 115 degrees) this past Fourth of July in our Greyhawk 29MV (one 15000 AC) proved to us that one AC is a struggle to keep up. We would have settled for temps of 78 degrees in the coach but that didn't happen. The best we got was 90 degrees inside.

So we ran to Sears and picked up two portable fans. That helped bring the temps down to 85 at mid-day I the coach. Night time temps were much more manageable.

[My garage]

Poor or no insulation around Windows slides roof vents floor vents and return area buy a temp gun and just look around but they blamed mine on ac vents sticking up to far going to factory service where it's been since May Iam ready for the bs they do NOT CARE
