There are models of ductless splits capable of functioning down to -20C (-4F) ... yes their efficiency diminishes as the temperature drops, but it still beats heating with EBB alone.

So for example, if you said, please smoke outside unless it is really cold, then you could quite easily notice that the temperature threshold which constitutes "really cold" could start drifting upward over time.

Notating the pressures/temperatures of the area and unit, whether they changed the run/start caps, checked wiring, cleaned coils, and how, etc.

Theoretically, you could disable the minisplits during the winter, so that they cannot be used for heating, and use a "dummy" thermostat in a prominent place, and have the real thermostat, set to 68, in a hidden place that they cannot access, but that reflects the temperature of the unit. 

Because there is overwhelming observable and measurable evidence that shows without a doubt we are in a time period of increasing ocean and land temperatures; changing weather patterns and increased frequency and intensity of events such as hurricanes, hail storms, wind events, flooding and wildfires; changing biosphere patterns; accelerating glacial melting at the poles and extreme northern and southern latitudes; and rising sea level just to name a few.

., though (lifestyle impingements).And I do realize this is mentally and financially hard on so many--hang in there--and ride the waves as they come in, and do the best you can (that's all anyone can do).And riding this thing out in beautiful Oceanside is a lot better than riding it out Wuhan China where they are welding people into their homes (the glass is either half-full or half-empty).Good Luck!

Have you checked the actual temperature in the unit?

I think I'm planning to just rent a motel room off and on for two months it's just TOO COLD after I saw the temperatures unless I can put up plastic inside a room to keep it nice and way for sleep area.

If the property were rendered inhabitable due things like fire, flood or temperature issues, you would need to credit back rent for the days it was inhabitable. 

He agreed with the tenant that the oven was getting much hotter than the set temperature.
