You might expect that adequate air circulation happens naturally inside a home, but it often doesn’t. Because today’s energy-efficient houses are tightly sealed and air exchange with the outdoors is greatly reduced, circulation of air indoors is likewise diminished and stagnation occurs. Adequate circulation of indoor air is vital to:
- Flush out odors, dust, and other airborne pollutants.
- Reduce accumulation of indoor humidity.
- Distribute heated and cooled air more consistently, eliminating cold and hot spots.
- Prevent mold and mildew.
Unfortunately, in certain seasons, simply opening windows to enhance air circulation isn’t an option. Here are some additional ways to maximize movement of air inside the house:
- Change the HVAC air filter regularly. Your heating and cooling system is an important ally in maintaining proper circulation. The air filter directly affects the airflow volume circulating throughout the house. Replace the air filter at least every other month during winter and monthly all summer.
- Install exhaust fans. Certain rooms, primarily the kitchen and bathrooms, need extra help as humidity and odors accumulate. Dedicated exhaust fans that pull humid, stagnant air out of the room and exhaust it directly to the outdoors should be installed to fortify circulation.
- Have the ducts inspected. If your home is more than 10 years old, chances are the HVAC ductwork that circulates conditioned air has begun to leak. In many cases, loss of airflow into the attic and other uninhabited spaces can exceed 25%. A qualified HVAC contractor can inspect the ducts as well as test airflow to quantify the extent of the leakage. Effective duct-sealing options can restore full airflow and maximize circulation throughout the house.
- Consider ceiling fans. To augment household circulation, ceiling fans are a great option. These slowly rotating fans generate gentle, continuous air circulation at a very low energy cost. In addition, ceiling fans are reversible to augment heating in winter and support AC cooling performance during summer.
