Whole House Air Leakage Testing measures how much air is moving into or out of your home through the thousands of gaps in the building shell. The infiltration of hot, humid air into your house in the summer and the exfiltration of heated air in the winter - both make your air conditioner/heater run longer and cost you money. Air leakage testing measures the amount of leakage and shows where it is.

Whole House Air Leakage
Blower Door Test
This simple test measures the "leakiness" of your house - how much air leaks into and out of it because of different air pressures indoors and outdoors. Energy is lost in summer as hot, humid air comes into the house, increasing the load on your air conditioner. In winter, heated air escapes to the outdoors. The Blower Door test measures the amount of air leaking into/from your house in cubic feet per minute - and also reveals the location of these leaks, so they can be sealed.
When applying spray polyurethane foam insulation to an existing home's attic, the Blower Door test reveals where gaps in the foam exist, helping installers to better seal the attic. This reduces the possibility of moisture problems.
Room-To-Room Air Pressure Testing
Discovering widely varying air pressures from room-to-room in your home can enable technicians to reduce the danger of carbon monoxide problems and of hot, moist, and dirty air entering the house.
