Air conditioning in Sunset: repair, install, ducts

We start with the indoor air handler, because electric heat in these Sunset homes depends on the heat pump, the heat strips, and the controls that tell them when to run. A loose wire, a failing contactor, a thermostat signal problem, or a weak strip can change what happens on a cold morning. The check follows the wiring, the control board, and the strip heat itself, since those parts carry the heating load here.

For houses in Sunset with attic duct runs, we check the duct layout from the air handler through the attic and out to the rooms. That means looking at the supply runs, the return path, the connections at the plenum, and the insulation around the ducts where attic heat can work on them. Outside, the unit placement matters too, because the line set and wiring have to match the indoor setup and leave room for service.

Older homes here can have original or patched ducts, small returns, and equipment that has been changed over the years. We look at the return size, the duct joints, the older wiring at the air handler, and any splices near replaced equipment. In a house built before 1980, those parts can all affect how the heat pump and strip heat move air through the rooms, so the check has to cover the whole path.

We check the heat pump, the heat strips in the air handler, and the thermostat calls before the first cold front reaches these homes. Since electric heating is common in Sunset, the indoor unit and its wiring deserve a close look before cooler weather puts them to work. The control signal, the strip heat, and the airflow through the ducts all matter, especially in houses and townhomes where the heating parts are tied to one indoor system.
