Your home and its environment can be a complex combination of systems and construction techniques that can have an impact on the indoor air quality in your home.
Does your home inhale or exhale? Homes should have a slight positive pressure (exhale) so that unwanted contaminants are not brought into the home. Your home heating and air conditioning system plays an important part in achieving this. Its installation, operation and maintenance are important.
If your home inhales it means it is being depressurized by some source or device in the home such as bathroom exhaust fans, combustion appliances such as a gas stove, fireplaces, dryer vents and kitchen exhaust hoods.
It is important for homeowners pay particular attention to:
· Fixing water leaks of any type.
· Maintaining a positive pressure in your home.
· Proper maintenance and service of your heating and air conditioning equipment.
· Upgrading of air filtration system
· Installation of ultraviolet light system.
· Proper weather-stripping of exterior doors.
· Sealing of all penetrations from the home to the crawl space and attic.
· Gasketing of all electrical wall sockets nd switches to prevent air leakage.
· Use of exhaust fan or heat recovery ventilator in bathrooms for moisture control.
· Maintaining a clean environment in your home and limiting the introduction of potential contaminants into the home.
· Use of a central vacuuming system or HEPA rated vacuum to prevent the redistribution of ultrafine particles coming out of your vacuum.
