Do I need to know anything about HVAC for the California B2 Residential Remodeling Exam?

Don’t sweat the fancy air conditioning stuff (HVAC) for the B2 Residential Remodeling Exam. While you won’t be replacing whole systems, you might see a question or two about existing HVAC during remodeling.

Think of it this way:

• Spot the vents: Knowing where the air comes in and goes out (vents and thermostats) can help you avoid accidentally wrecking them during your remodel.
• Plan around the air movers: Understanding how those air ducts (chases) and vents might affect your design or finishes could be handy.
• Safety first, even with air stuff: Basic safety knowledge, like not messing with electrical wires near thermostats or respecting high-pressure areas, is always a good call.

The main takeaway is that they care more about your remodeling skills and how they work with existing HVAC, not turning you into an air conditioning whiz.
