A/C unit upgrade?

[Weedy]

I have a 2014 journey 34b with two 13500 tru air a/c top side. Can I replace them with 15000 btu ones ? Have 2000 w inverter. Any recommendations for the most quiet also ?

First... your inverter has nothing whatsoever to do with your roof mounted A/C units.

You might be able to replace 13.5K units with 15K units. The problem for you can be the thermostat. It's hard wired to your A/Cs and sometimes you can only use the exact same units as you are replacing.

You mentioned "True Air" but I thought those were the basement A/Cs on older Class A RVs... not roof top units.

Get the exact model numbers of each A/C and call the manufacturer and ask about this upgrade and compatibility with your thermostats.

FYI - there will not be a huge difference in cooling between 13.5k and 15K. It will use more power (amps) to power them but it's likely your RV has circuits set up to handle the extra amps.

These are much quieter, I hear, but are still 13,500. You may want to contact AirExcel on compatibility. Here's the sales pitch, but I've read a positive review of them, too.
