A/C issues in Texas

I know it's February but here in Texas we alternate between high 70's and low 40"s. My heat pumps units (2) work fine but lately when switching from heat to cool the units take a long time to cool the coach. ( we have to sleep in a bedroom that borders on frigid but that is another story) The units only run for a brief time (couple of minutes) and then cut off without properly cooling the unit and cut back on in 5 or 10 minutes for another brief time. Both units do this and one is only a year old. After a period of time they tend to stay on longer and eventually cool the coach. Never had this issue in the 3 years I have had the coach. Do you think this may be a thermostat issue? Filters are clean. Or is this normal when switching from heat to cool?

Any chance you'd be able to shut off the AC and let it rest for 15 minutes before switching to the other mode? I think the lack of an internal baffle is pre-heating the safety shutoff (thermal disk device) on the AC when it's in the heating mode then it doesn't return to the AC mode fast enough.
