Setting up a sleeping section in barn plus considering the installation of ductless heat pump

I am currently leaning toward a ductless heat pump, which would supply both heating plus cooling capacity.

I own plus operate a small stable, which is situated nearly fifty miles from our home. I stable a half dozen horses plus need to feed plus care for them everyday. The drive gets super bad plus discouraging. My goal is to set up a small home within the barn, where I could stay a few mornings a week. It could be very simple, with little more than a bed, refrigerator, toilet plus sink. I would also need some type of temperature control. The weather in the local section is often severe. In the winter, it isn’t unregular for the temperature to drop below freezing for weeks at a time. During the summer, the people I was with and I deal with excessive humidity plus temperatures in the upper eighties. There is no insulation in the barn plus very little ventilation. Because there is access to electricity, I have considered making do with a portable air conditioner plus a space heater. This solution wouldn’t cost much or require professional installation, but wouldn’t suffice while in extreme weather. Since I dislike driving on snowy roads, while in blizzard conditions, I’d like a more powerful furnace. I am currently leaning toward a ductless heat pump, which would supply both heating plus cooling capacity. The heat pump would take up very little space, run quite efficiently, plus combat any weather. However, I’d need to hire an Heating plus Air Conditioning corporation to handle the installation, plus the machine comes with a hefty price. A benefit of the ductless heat pump is that it could heat up or cool down the space very suddenly. I would only operate it while I’m on the premises, which would keep the running costs very low.
