Winnebago 30T A/C -

This is our second summer in the 30T. In 80 to 90 degree temps the A/c does not cool the coach below 85. Is this all we can expect or could there be a need for service. It did not perform any better last summer when it was brand new. Any thoughts?

We have a 31' Jayco. 80-90 is pretty mild in Texas. It's got a 13.5K BTU Carrier unit. It cools well enough in 80-90 degrees.

To test if your unit is working right, there should be at least a 20 degree drop between the incoming air and the air at the vents. You'll need a thermometer. Measure it and report back.

Ducting decreases AC efficiency, in my experience...

Dont let inside get hot, then turn AC on to cool it off

You must let the AC get a head start on getting the inside cool, before the big afternoon heat develops.

Use a box fan to help circulate the cooled air.

I had a 28' toy hauler...1 15k Dometic...it worked as well as could be expected in the sunny mid 90s degree days..once sun went down...it make the inside a meat locker
