HVAC ceiling vents
We have a 2008 Lexington 283 gts. On our last trip to Florida we used our AC almost non-stop. We noticed that the driver side ceiling vents from the front through the kitchen, bath and bedroom had minimal air flow. We have only 1 roof mounted AC unit so there is only 1 zone for the thermostat controller to control.
Does anyone have suggestions as to what the problem maybe or possible solutions? Also, are there any tests that I can do to verify the problem?
Thank you for your time and knowledge.
