What Is Whole House Ventilation The 4 Different Types

A whole-house ventilation system uses mechanical fans and ductwork to replace stale indoor air with fresh outdoor air throughout your entire home. Expect to pay $1,700 for a whole-house fan or $2,000 or more for an ERV system , depending on your climate and home needs. Your climate determines which ventilation system works best: exhaust-only systems suit cold climates, while supply-only systems ...

Types of Whole House Ventilation Systems & How They Work Exhaust Ventilation Systems Exhaust ventilation systems remove indoor air, creating negative pressure inside your home. This pressure difference draws fresh outdoor air into the home through intentional vents or natural leaks in the building's envelope, such as around windows and doors.
Whole House Ventilation System

A whole-house ventilation system uses dedicated fans, ducts, and controls to continually replace stale indoor air with fresh outdoor air at a measured rate. Unlike a bath fan or cracking windows, it c...
A whole-house ventilation system uses a mechanical ventilation system to exchange stale air for fresh air for your entire home. A whole-house ventilator can provide multiple air exchanges a day and is most effective when connected to your HVAC system , including your smart thermostat.

Is a Whole
A whole-house ventilation system is a mechanical ventilation system that expels stale air and replaces it with fresh, outdoor air. The ventilator can provide constant ventilation , whether your HVAC system is running or not.
How whole-house ventilation works Whole-house ventilation uses one or more fans and ducts to move air on purpose, not by chance. Depending on the design, the system draws in outdoor air, filters it, and delivers it to living areas, while stale indoor air is exhausted from rooms that generate moisture and pollutants (bathrooms, kitchen, laundry).

2026 Whole House Ventilation Guide
A whole house ventilation system is a mechanical component integrated with your HVAC system designed to provide controlled, continuous air exchange across all rooms. It works by either exhausting stale indoor air while drawing in fresh outdoor air or using balanced methods with heat recovery to maintain energy efficiency.
Whole-house mechanical ventilation is the intentional exchange of indoor air with fresh outdoor air at a controlled rate using fans. The purpose of whole-house mechanical ventilation is to improve indoor air quality.
