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.

What might be a question about HVAC that would be on the California B2 Residential Remodeling Exam?

Here’s an example question you might encounter on the California B2 Residential Remodeling Exam that touches on HVAC:

Question: You are remodeling a kitchen and the existing layout places the new dishwasher directly in front of a supply air vent. What should you do to maintain proper airflow throughout the house?

  • A. Leave the dishwasher location as planned and install a smaller vent nearby.
  • B. Relocate the dishwasher to a different spot in the kitchen layout. ** (Correct)**
  • C. Block the vent temporarily during dishwasher installation and reopen it afterward.
  • D. No changes are necessary; dishwashers do not affect airflow.

This question tests your understanding of how existing HVAC elements can impact your remodel. The best answer (B) avoids blocking the airflow by relocating the dishwasher.
