Homeowners, take comfort: Even the appliances on Air Force One break down.

More than a quarter-century after they were installed, two of the refrigerators on the president’s plane need to be upgraded, and these specially designed “chillers” aren’t cheap.

The Boeing Company was awarded a nearly $24 million contract in December to engineer the refrigerators for Air Force One, the Defense Department said.

The two units being replaced came with the aircraft in 1990 and are no longer able “to effectively support mission requirements for food storage,” the Air Force said in a statement on Saturday.

“The units were based on the technology at the time and designed for short-term food storage,” the statement said. “Although serviced on a regular basis, reliability has decreased with failures increasing.”
