Usually, most regions are in need of all three depending on where you live and what time of the year it is
It took me years to finally discover my path in life. I always knew that I wanted to work with my hands, I just didn’t know in what capacity what would happen. I toyed with working in kitchens for the rest of my life, but I couldn’t handle the constant yelling from chefs and the maddenly stressful work environment. At first I had a decent job while I was in high school and I had manageable stress with supervisors who weren’t type-A personalities with loud yelling voices. Sadly, that all changed when I got a job at a bigger kitchen in my early 20s. It was hard too when you’d randomly get thrown in dish duty because the managers didn’t want to hire enough dishwashers to keep up with the full capacity each evening. So I did what many do in my situation and I went back to school. I decided to attend trade school this time and immediately took a liking to the heating and cooling industry. There’s a lot of job security working in HVAC as well so I knew that I’d surely always have access to some kind of job. It doesn’t matter what kind of climate you live in, you’re always going to need either heating, cooling, or air filtration. Usually, most regions are in need of all three depending on where you live and what time of the year it is. While we have our winters between November and March in the northern hemisphere, places in the southern hemisphere have their winters when we have summer. You could move anywhere in the developed world and find a need for some aspect of HVAC work, even if it’s only in commercial or public buildings.
