A door gasket costs very little and is almost never replaced until the unit is already struggling, by which point the compressor has been running long shifts for months to make up the difference.

Not as a failure. As a slow drift: a unit that used to hold temperature comfortably and now runs closer to its limit, especially in the afternoon.

Seals are checked at every visit and replaced when they stop sealing rather than when they finally tear. It is the least interesting line on an invoice and one of the few that pays for itself.
