If your Northwest Arkansas home is newer or tightly sealed, your indoor air quality may be lacking. Particles such as mold and bacteria and gaseous pollutants can cause a range of health problems. A whole-house ventilation system is ideal for keeping your indoor air clean by mechanically replacing stale indoor air with fresh outdoor air.
The four types of whole-house ventilation systems are:
- Supply systems force outdoor air inside, depressurizing your home so that stale air is forced out through air leaks in your home’s shell.
- Exhaust systems force indoor air outside, pressurizing your home so that stale air is forced out through air leaks.
- Balanced systems bring in outdoor air and and remove stale indoor air in equal amounts, neither pressurizing nor depressurizing your home.
- Heat recovery and energy recovery systems transfer heat from outgoing air to incoming air in the winter and vice-versa in the summer. Energy recovery systems also transfer humidity from outgoing air to incoming air in the winter and vice-versa in the summer.
When choosing a ventilation system, look for these features to ensure optimum performance based on your needs.
Choose a ventilation system that has a noise rating of less than one sone.
As with all new appliances, choose a product with the Energy Star label to ensure efficiency. Make sure any ventilating fan is properly sized to lower your operating costs.
Choose a system with the controls located in an out-of-the-way space, such as the basement, to prevent accidental shutdowns. Turn the system on when your home is occupied, leave it on the lowest setting at all times, or install a programmable control that lets you program operation based on your schedule.
A good ventilation system will utilize in-line fans to ensure optimum distribution of the fresh incoming air. Make sure your qualified installation technician tests the system for distribution before packing up and leaving.
