Climate change made this a future-proof trade. As the world gets hotter, demand for air conditioning and cooling keeps rising, and there's a real shortage of skilled technicians. That makes it well-paid and in strong demand — it's only going one way.

The self-employment is great — call-outs pay well, and a skilled technician with a good client base earns very well. I qualified, got my F-gas certification, built experience, and now I run my own business. Cooling always needs installing and maintaining, so there's always work.
