Air sealing affects air quality in your home
Air quality is not just an issue for the great outdoors. Families need decent air quality inside their homes for a healthier and happier household. And yet, so many of us may not be aware of poor air quality in our home. We operate with the feeling that as long as there isn’t a stench in the air, or smoke from the oven or fireplace, the air quality is probably pretty good yet, that is not always the case. Likewise, many homeowners don’t realize the health benefits or potential energy savings of air sealing their home.
Air leaked into your home brings with it unwanted moisture, pollutants, and temperature differentials. When a home operates under different pressures from HVAC systems and normal every-day appliance use, outside air will find its way in. That’s why air movement through the windows, doors and roof should be restricted.
Are those areas properly sealed in your home? There are a lot of places in the attic and crawl space that should be air sealed. Holes cut for plumbing pipes, vents, wires, and HVAC ductwork and returns are notorious areas for air leakage. All those little holes can add up and affect air leaks/air quality in your home. In fact, according to the Department of Energy, if you added up all the leaks, holes and gaps in a typical home, it would be the equivalent of having a window open every day of the year!
Sealing leaks and adding insulation can improve the overall comfort of your home and help to fix many of these related problems:
- Reduce noise from outside
- Less pollen, dust and insects (or pests) entering your home
- Better humidity control
- Lower chance for ice dams on the roof/eves in snowy climates
The vast majority of existing homes could use some improvement with their air sealing. You can tackle sealing those air leaks on your own if you’re relatively handy, or you can consult an energy expert for assistance.
Ultimately, you want to properly seal your home. The sooner improvements are made; the sooner gains can be realized. It’s hard to put a price on being comfortable or on indoor air quality. We can definitely put a price on energy efficiency. Air sealing is the first step in any energy improvement plan for your home.
