Hi Stacey, I only have one AC unit. I'll take off the vent covers and check the ducting and air return filter. Yes it is a heat pump. I was in the direct sun with no shade. I've looked at the gasket under the shroud and it looks good. Could be the gasket between AC and roof but I'll have to find a tech to check it as I don't like climbing on the roof anymore. You weighed my trailer years ago in Lake Havasu City at a Sunshine RV rally. Thank you for the suggestions. Walt
