If you’re building a house, you may be wondering which ventilation system would be best to install. There are three main types of systems for residential buildings which release and supply air in different ways. Here’s some basic information about each of them to help guide your decision.

What Are Some Common Ventilation Systems?

Exhaust Ventilation Systems

Exhaust ventilation systems force air from inside a home out through an exhaust air outlet. Then, air leaks in from outside through holes, ducts, and vents, which works to depressurize the building. Though used in Oregon, this type of system is better for people living in cold or dry areas because the intake of unfiltered humid air can lead to moisture damage. It’s probably not the best choice for those with breathing or immune issues, because pollutants like mold, dust, and flue gasses can come into the house as it is depressurized.

Supply Ventilation Systems

Supply ventilation systems are essentially the opposite of exhaust systems. The goal is to increase pressure inside a home by forcing air from the outside in and allowing the air inside to escape through holes, ducts, and vents. The incoming air is filtered for allergens and humidity, so this type of system is better for people who suffer from allergies or those in moist climates like Oregon’s.

Balanced Ventilation Systems

Unlike the first two systems, balanced ventilation doesn’t add or take away pressure from a home. Air is forced in and out of the space in roughly equal amounts using a supply fan and an exhaust fan. The system is usually set up to bring fresh air into places where people spend the most time, like living rooms or bedrooms. Conversely, air is pushed out of rooms where moisture can easily develop and accumulate, like bathrooms or kitchens. Because this type of system uses multiple fans and ducts, it may be more expensive to install and run than an exhaust or supply system.
