Air sealing your home is a cost effective way of improving energy efficiency and comfort because it decreases the amount of air that enters or escapes out of your home. According to Energy Star, homeowners can save up to 20 percent on heating and cooling costs by air sealing their homes.
Before you air seal your house
Prior to air sealing, you should:
- Inspect for air leaks – You probably know where the obvious air leaks are, but to properly air seal your home, you’ll also need to locate the least obvious air leaks. Hiring an HVAC professional to conduct an energy assessment of your home can provide you with a complete inspection of your home for air leaks.
- Determine your ventilation needs for indoor air quality – Proper ventilation is important for an energy efficient home. Good ventilation helps control moisture to prevent mold growth and structural damage. A qualified HVAC professional can determine the level of ventilation that will improve your home’s indoor air quality.
How to air seal a house
There are three components to consider:
- Sealing leaks – Caulking, weatherstripping and spray foam are the most common approaches to sealing obvious air leaks such as around doors and windows. These methods may also be applied to hidden leaks in crawl spaces, attics and the basement.
- Add insulation – Properly insulating your home is important when air sealing your home. The recommended level of insulation in your attic is about 12 to 15 inches.
- Seal ducts – About 20 percent of the air moving through a home via its ductwork is lost because of leaks or improper sealing. An HVAC professional can repair your ducts with a duct sealant. Properly sealed ducts can keep your energy bills low and your home more comfortable.
