What size are the units? You may have to upgrade them or add a third unit.

You might have an issue. Of course, our dark paint doesn't help!

I can usually keep my 45 ft cool with 2 units...just fire the 3rd to make it easier.

Cooling became MUCH easier when I added the Magne Shield front windows shades...truly amazing reduction in heat up front.

I would see about a recharge. See if the AC air is coming out at the cold temp rating. I have a 42' and at a 100 it still can keep the coach cool

I too am able to keep my 42 ft cool with two ac's. The MCD shades all around likely help some.

If you have overhead cabinets in the front of the cockpit open them & see if it is hot inside them. If it is you probably have no insulation in the front cap. I am in the process of insulating my front cap right now. Luckily I have access thru the TV cabinet. Both the front trim & the rear louvered cover snap on & off. Also you probably have a lot of heat coming thru the windshield. A Magna Shade is next on our list.

Get a digital laser thermometer and measure the air temp at the AC inlet grill and the close AC vent. There should be About 25 degrees difference. If not the Unit is bad and needs checked. These units are sealed disposable. I also painted the area on the top front, sides and back that was the coach color with white Rv roof paint. The paint made world of difference in cooling the RV. I did not paint the normal white RV fiberglass roof that my Coach has.
