I have a new sportscoach cross country 404rb and need help on AC. The controller I have is a domestic, I have two zones. I have set both on auto and at 67 degrees. The master gets down right cold but the coach does not seem to. Middle of coach ceiling is big vent which all the openings wide open and when u stand under cold- but all other 9 round vents very little comes out. Cabin pleasant when coming in coach but after awhile not so. Been in Galveston 4 days and AC still on. Also drivers AC up front(like normal car etc) starts out cold when driving but later feels just like a fan. Someone said maybe AC unit bad or not sealed right. Just curious if anyone else having this problem

The vents under the unit need to be closed to force the air out the vents.

Our ac has that big vent. It's called ac dump and is used for faster cool down then when you get close to your temp setting shut vent and use your ceiling vents

Also with the dual zone thermostat you want to set it on cool as auto is heat and cool depending on the temperature.

Thank u. Getting it looked at next week anyway. Did not realize to put on cool rather than auto. I did what u said the last night we were there. I was told by coachman that it past they had trouble with AC. They told me that I should look at round vents furthest to front put fingers in forward and c if they blocked AC from going further front cause it would end up in ceiling. I did not feel blockage. The other problem was the coach drivers air would start cold then warm like out of freon, getting looked at next week. Thanks
