Building a Healthy Home: Beyond HVAC

HVAC is the heart of indoor comfort, but IAQ is a team sport. Complement your system with:

• Source control:

• Store solvents and chemicals in sealed containers outside of living spaces.

• Fix water leaks quickly to prevent mold growth.

• Housekeeping:

• HEPA vacuuming and regular dusting reduce particulates.

• Wash bedding weekly in hot water to minimize allergens.

• Ventilation:

• Use kitchen and bath exhausts during and after cooking or bathing.

• Consider an ERV/HRV for continuous fresh air exchange.

• Plants and furnishings:

• Choose low-VOC furniture and finishes.

• Be cautious with scented products.

Small lifestyle choices reinforce your HVAC’s efforts, creating a healthier home ecosystem.
