Dan Riepe measures air leakage in a house with an infrared camera which displays warm areas of a house in hotter colors. "The average house blows out 30 (percent) to 50 percent of the air out of the house. Meaning your air conditioner has to work 30 (percent) to 50 percent harder to keep the house cool," Riepe said.
