Step by step

What an AC replacement involves

  1. Set the unit

    The outdoor unit: set level on its pad, with room to breathe and service.

  2. Run the lines

    The line set: the copper lines between outside and inside, replaced or cleaned, insulated and sealed through the wall.

  3. Match the coil

    The indoor coil: matched to the outdoor unit and sitting on the furnace or air handler, with its condensate drain run.

Do I need a permit to replace an AC unit in California?

Expect to. Changing out an AC is permitted work, and depending on the job the permit brings HERS testing with it. Check your own city's page; ours are in the permit guides.
