I'll bite.

If you are talking about a forced air heating system, differential pressure could mean the difference in pressure at various locations in the blower/ductwork system. Like before/after a filter or before/after the blower.

Also in a heating system duct it could apply to the measured velocity pressure to duct pressure difference. This differential pressure allows you to calculate the air velocity in the duct.
