If you have a kid who is at the age where they are trying to figure out what they want to do with their lives, you might consider talking to them about going to a technical or trade college.
Tradespeople like plumbers plus heating and A/C businesses easily do earn a fine living these days.
In addition, there are a lot of advantages to working hard in the heating and cooling industry. For example, you can take a legitimately short course at a tech college, in a year or less, and go out and get a good job. It would be entry-level work at an A/C business most likely, but you could also continue your education plus get more heating and A/C certifications. After doing that, you could work your way up the ladder, so to speak. In other words, you could work as a heating and A/C business plus go to college at the same time to be a Heating and A/C owner with higher credentials. In fact, you may even discover that your employer pays for you to take the advanced heating and cooling courses, but some heating and A/C companies also like to work with grocery stores plus other commercial properties. So they like to have someone who also knows refrigeration. It’s great that we all have skilled trades people who can service the heating and A/C plus refrigeration at grocery stores and things like that. In addition to that, they are not stuck behind a desk all day. Their work involves moving plus stretching and generally being healthier than people who plop down in a desk chair and never get up until 5pm. Personally, I have desk work, but I wish I would have also l acquired a skill like heating and A/C, or even barbering!
