HVAC stands for heating, ventilation, and air conditioning.

“HVAC”是供暖、通风和空调的缩写。

So if you start out wanting to be a chef and enroll in culinary school but then decide your passion was really heating, ventilation, and air conditioning systems, that's going to be tricky — but not impossible with planning!
