AIR8 not cooling adequately

in Air Conditioning & Refrigeration
Owner of a 2021 TAB320S here. My air conditioner is not cooling as what is expected from my unit. I’ve cleaned the filters on the Air8 unit located under the passenger side seating. I’ve got the setting to full cooling mode. It’s actually hotter inside the trailer than outside (90 inside and around 80 outside) We’re mostly full time and haven’t experienced this issue in the past. My dealership I purchased from is lackluster and usually has a waiting list that can be months out. I’m in Florida in summertime so I’m not expecting an icebox, but I know the unit can do more to keep cool. I’m not sure what my next steps are so I’m here looking for suggestions, thank you in advance

    From the Installation Manual                             { i have no direct Air8 experience }

    Are you getting any Error Codes on the Display Panel ?

    Elwell claims to have a Service Center in Vancouver, WA.

    You might attempt to contact/locate them and see if they can provide basic troubleshooting guidance.

    May require some effort - - - limited web-information seems only focused to selling stuff to manufacturers - - -

    I got an immediate response from an inquiry to that email.  I think it is a well run company from my experience.
    I don't have the experience of hot humid conditions with my AIR8 but past experience with a CoolCat has shown dramatic results from a simple partition to assure the hot exhaust air is not mixing with the inlet air on the outside vents.  On my AIR8 it looks like a flat panel extending down from the frame would help separate those areas.  Maybe held in place with magnets when parked...  You've got me brainstorming because I had to do something similar for my CoolCat.  There are other similar posts for other installations used in T@Bs.

    It seems like there was an issue with a Thermostat sensor:  https://tab-rv.vanillacommunity.com/discussion/13995/air-8-thermostat

    I've also noticed lackluster performance from my Air8 this season. Haven't had a chance to troubleshoot yet, but it's definitely having a harder time cooling than it did last summer.
    I do need to look into a baffle for the air outlet. Will probably try to 3d print one.
