What the job started with
Two halves of one system, changed out together
This Antioch house in ZIP 94509 is heated and cooled by a split system: an outdoor unit beside the house, next to the brick chimney, and an indoor air handler standing in a corner of the garage that feeds the ducts through the ceiling.
The job replaced both halves at once, sized together at 3 tons, rather than pairing a new outdoor unit with an old indoor one. The city treats that as an HVAC changeout, so it was done on a City of Antioch building permit with its own final inspection.
The work
What the job involved, in order
Permit
The City of Antioch issued a building permit for a residential HVAC changeout: replacement of a 3-ton heat pump outdoor unit and air handler.
Take out the old equipment
The old outdoor unit beside the chimney and the old indoor unit in the garage were disconnected and taken out.
Set the new air handler
The new air handler went into the garage corner, joined to the foil-wrapped supply plenum that carries air up into the ceiling, with a white condensate drain line and the insulated refrigerant line run down its side.
Set the new outdoor unit
A Goodman heat pump unit was set on a pad against the house wall and wired through the disconnect box above it.
Final inspection
The permit's final HVAC changeout inspection was signed off in June 2026, and the homeowner signed the job off as complete the same month.
How it ended
A matched 3-ton heat pump system, inspected and signed off
The house now has a new outdoor unit and a new indoor air handler, sized to each other at 3 tons, so one heat pump system does both the heating and the cooling. The changeout is on the city's record through its permit and signed final inspection.
