I'm not familiar with the climate you're in except it gets cold and snowy. After spending over 20 years on open station tractors, I built a heated cab for the last tractor. The ventilation was via doors that lifted off easily when the weather got warm. With a small fan and the doors removed, it was better than an open station in the hot sun.
About 1-1/2 years ago I had the opportunity to move to a factory-cabbed tractor with both heat and A/C. It was a huge improvement over the heated-only cab. Being able to keep cool on the hot days in itself is great. Other benefits include watching the bugs, deer flies, etc bounce off the glass instead of biting me. Not sneezing and wheezing in Pollen Season and Dust Season, and driving without ear protection are nice.
