On April 14, 2011, the NY Times published an article, "High Costs Linked to Gaps Around Air-Conditioners," on Page 22 of the NY Edition, the Science Section, under Environment. It highlights the problem of both heated and refrigerated air escaping apartments due to the gap around air conditioners.

The report, titled "There Are Holes in Our City's Walls," estimates that poorly fitted air-conditioners cost buildings in New York City $130 million to $180 million a year in extra fuel consumption, which in turn is linked to an extra 375,000 to 525,000 tons of carbon dioxide emissions."
