I have 1999 30 foot c with a large slide. The ac unit has been checked and the technician states it is performing correctly. But it does not cool very well when it is hot, like 90's hot.
1. can I replace the 13500btu unit with a larger one? Would it really make a difference?
2. Could I add one of those portable units to supplement the current unit.
I am on a budget. Any Suggestions?
I have cleaned the unit and done just about everything I can. My unit just doen't seem to be very well insulated and heats up pretty fast.

Yes, you could replace it with a 15K and it will make a difference. But, if you have room and don't mind the noise, adding a portable unit to supplement your current AC will work the best IMO.

you might have to run a dedicated 110 line to the pedestal to power just the standalone a/c unit. also, you might want to check the air temperature coming out of the a/c against the temp at the intake grille. 15 to 20 degrees is the normal range. anything less is a problem.

How did you clean the unit? Did you or whoever helped you do everything noted HERE?
I ask because I think a 13.5 should be at least adequate. The 15.0 in our low-budget 31' (but no slide) is more than adequate. Cools cold and fast.
We cleaned a 25-year-old 13.5 Coleman Mach on our old 24' and it went from "time to replace" to "blowing cold." We were stunned at the results.
If you go to a 15K unit, your current demand will tax 30A service. I hope you're running your AC on a service that keeps the voltage up. You'll lose performance if it gets down to/below 110. I moved our coach closer to the campground pedestal so I didn't have to use our 30A extension cord. Voltage went from 109 to 115.

Thanks for the suggestions. I did clean all the fins, inside and out and sealed off anywhere that outside air could get into the ac unit (at least the best I could) It does blow about 15 degrees colder than room temperature. I might try a portable unit, I think I have 30 days to return it if it doesn't work for us (mostely worried about noise). Thanks

Just a thought. You could take out a roof vent in the beadroom and put a another 13.5 ac unit in and run a 110 line to your pedistal.

NONE of the RV A/C units can keep a MH cool when the temps reach 90.
Instead of adding a unit you need to add things to the MH to keep the "heat out" like all the rest of us have to.
First in a Class C you have to cover the cab area from the coach area or your MH will never get cool. This is where MOST of the heat comes in thru the windshield and side windows. Also make sure the vents for your chassis heater/ac are closed before you shut the engine off.
Cover all roof vents with vent pillows. A ton of heat comes in from these plastic flimsy not sealed vent covers, and you loose a lot of air thru them too.
Park facing north or south.
Add windshield sun shades to the 'side' windows where the sun is coming in.They fit right under day/night shades, no taping, velcro necessary.
Put awning out and placed in it's lowest position. Face your MH so that the awning is on the side where the afternoon sun is.
And if you really want to get serious about seeing how cool you can keep your MH in the heat....add a de-humidifier to assist your A/C. I did and it is unbelievable what a difference it makes.
Adding these insulating items to help the A/C will drop the temps in your MH by 20 degrees.

I bought a small window unit to add A/C capacity. The are quite cheep at Home Depot and Lowes. The good part is they are light weight and can be installed in minutes and removed in seconds. You can add 6000 BTU's cheep.

A dehumidifier works just like your A/C, EXCEPT that it WARMS the interior as well as removing moisture.
Your A/C removes moisture, and COOLS the interior.
