Breathe Better Air

Because we are spending a large percentage of time indoors, the quality of air in our homes is critical. In many homes, excessive duct and building envelope leakage is the main cause of poor indoor air quality and this affects the health of the entire family.

Building Envelope and Pressure Imbalances

Our homes are constructed with penetrations in the building envelope (the air conditioned, livable portion of your home) connecting our indoor air to that in the attic, crawl space and exterior of the home. These penetrations, coupled with pressure imbalances caused by heating and air conditioning system, wind, attic ventilation, etc., allow pollutants to enter into the home.

Air Condition System Leakage

Leaks in the HVAC distribution system can pull pollutants and irritants directly into your house. These pollutants are drawn into the duct system from the attic, crawl space or garage and are then redistributed throughout your house when your furnace or air conditioning system turns on.

Common pollutants and irritants that are drawn into your house by duct leakage include:

• Pollen and dust
• Insulation and material fibers
• Truck and automobile exhaust
• Mold and mildew spores
• Vapors from stored chemicals and insecticides
• Carbon monoxide

During the Home Performance Analysis, REEis technicians utilize a special diagnostic test called a blower door test to identify the leakage which exists in your home.
