Fresh air

What ventilation does

A tight house holds heat, and it also holds cooking smells, moisture and stale air. Ventilation brings outside air in and sends inside air out on purpose, through fans and ducts sized for the house.

When it is part of a system change

When we replace a system, add ducts or build out an addition, we look at the ventilation at the same time, because the rules and the air both change.

The rules that come with it

California's 2025 Energy Code applies to permits applied for on or after January 1, 2026, and it covers heating, cooling and ventilation work.

Depending on the job, ventilation work under a permit may need HERS testing.
Homeowners can choose a HERS rater independent of whoever installed the work.
