I recently bought a 2016 BigHorn 3970 RD, it has the 2 15k ac units. I'm in Texas, the other day it was 85 outside and it wouldn't cool below 74. Granted, door side is facing west, there's alot of heat gain on the windows/door, but it should do better. I've already taken it back to dealership and they replaced the living room AC due to my complaints, I'm now realizing it's the ductwork design.
I have one supply in the living area that puts out literally no air flow, when you take the vent off, you can feel air rushing over, just none is coming down into the cabin. when both units are blowing into the same duct per the design, they fight each other and create static pressure issues. The ultimate result is that all the CFM isn't getting down into the cabin. 30k btu should be plenty to cool that cabin, but it's only getting an 11 degree temp drop at 85 degrees, with door shut all day and all shades down.. At 105 it's going to be unbearable. Has anybody had any luck with the Whisper Quiet system in hot temperatures?
There has to be a workaround to modify the ductwork to get all the air into the cabin.
Disclaimer: I own an AC company so I know a thing or two about duct design.
If someone could contact me to elaborate on the design I'd appreciate it.
Also, any tips to reduce heat gain on windows, over and above the pull down shades?
