13500 btu versus 15000 btu

[suz155]

Hello all,

Still looking at the different B's and comparing. I live in Southern Texas and summers can be brutal. Still work full time and I can not "get away" to the mountains on a weekend trip, too far. So, the r/v staying semi cool, is important.

I did notice some r/v's have 13500btu's(most)and some have 15000btu's Does that make a difference in the temp in the vehicle or is it negligible?


Thanks

A Coleman 13.5K PS will use less AMP's

I looked at the RV size and stick with my suggestion.
Remember that an A/C too large isn't as effective as the proper size one.
Your Generator will also thank you and as someone mentioned you can use a 15 amp circuit when at home. Just make sure the circuit is dedicated for the RV and doesn't have other house stuff plugged inside the home.
Happy travels.

EDIT------Unless the unit comes with a heat strip in the A/C I would never pay extra for it.

Hi,

I'd go with the 13500--that way it can be run safely on a good quality 15 amp circuit. (i.e. at your home). The 15000 is just that little tiny bit harder to run.

If a heat pump is an option--I'd go with a 13500 btu unit.

How big is this RV?

I think a 13,500 Btu A/C is going to cool the small space so quickly, and will not take the time to dehumidify the air in the RV. A larger air conditioner will cool it even faster, leaving most of the humidity in the air.

I have a 30' long RV that is well insulated (as RV's go) with lots of windows, and 240 square feet of roof. I lived in Phoenix with one A/C unit when some days reached 105 and others 110. While not "Cool" inside, it was cooling the RV and reasonable inside.

So make sure that your roof is white, and get the 13,500 Btu air conditioner. If you plan a lot of winter camping, or using the RV as a extra bedroom while at home, you might consider a heat pump so you can warm the RV too.

I should have mentioned , I am looking at the Sprinter based B's. They, for the most part, have the 13500.

Definitely the 15000 if you have the choice. When we read people complaining about their AC, it is people in the SW heat with a smaller unit. In fact, LTV has now switched to 15000 units for that very reason, but only in their small C units. Their B's still get 11000 ac units. I checked Roadtrek and Pleasureway sites and they seem to only use 10-11000 units too.

So, I am not sure what B's you are seeing with 13500 or 15000 ACs.

Probably depends on the size of the B.
In warm climates I would go with the big one.
