Ac not blowing hard.

[Gordon429]

I have Fuzion 429 with 3 ac units. We noticed that the AC in the main room/living room is very uncomfortable and does not blow hard. Any tips and tricks? I know the master bed AC and main living area run on the same track. Has anyone blocked an air vent to try to forse more air out?

Welcome to the forum Gordon. We have a 2016 Fuzion 420, with 3 A/C units. If you do a search on here you will see that others have had some success taking the cover off the units, inside the camper, and checking for anything obstructing the air flow. I did this and had some increase in air flow, but not enough to matter. I finally just eliminated the flow through the duct work and now have all 3 units dumping air straight down. The center unit, zone 1, is above the loft, I put a 20" fan up there only when it's very hot outside and it keeps the camper quite cool. Also, I generally have to cool all 3 zones, so I set the thermostat at our desired temp, for all 3 zones and put all 3 on auto and leave it. Turning the A/C's off at night and waiting until the camper heats back up before turning the units back on is the kiss of death.

Great idea with the fan in the loft!!! I’m going to do the same thing! Thank you so much for your response!

In my post here: http://www.keystoneforums.com/forums...ad.php?t=38150 you can see what might be part of your airflow issue.

I found that my ducts had a lot of dead space at the end. I plugged up the extra duct and my airflow increased a lot.

Thanks all. I am picking the 5th up tomorrow for a small weekend trip. I’ll pop the AC panel off and let you know what I find!

Why? Thank you for explaining why not to turn off at night. Too cold if I don't.
