4. HVAC Systems
HVAC stands for “Heat, Ventilation, and Air Conditioning.” It goes standard in a new American home, and it takes tens of thousands of dollars if you want it installed in an old house. So some people want to try it on their own to save money. However, you should think more carefully.
To get certified in the HVAC job, people need to apprentice and take many tests before they can qualify to do housework. Like being a plumber, it takes a very long time to learn those skills. So thinking of an amateur jumping straight into a project is quite unrealistic.
