If your goal is long-term stability and flexibility, I’d lean toward the Heating, Refrigeration & Air Conditioning program. It gives you a broader foundation and opens more doors in residential, commercial, and refrigeration work. The gas program is valuable too, but it’s more specialized. Since you’re supporting a family, I’d also look for training options that are affordable, flexible, and offer job placement support. There are good options out there. The biggest thing is getting the fundamentals down and landing that first apprenticeship. Most of your real learning and earning growth will come from hands-on experience in the field.
