Walnut Creek AC repairs: a blocked fan and a leaking indoor unit

Water from a ceiling-mounted AC

The AC shut off after running for several hours, and water poured from the indoor unit. Its hinged filter-access panel was stained where water had run across it. We cleaned the condensate drain. The photos show the ceiling-mounted unit and the access panel.

Debris around a GE Zoneline fan

We slid the GE Zoneline AZ65H07DABW2 out of its wall sleeve to reach the components. Debris around the condenser fan was keeping it from turning properly. We removed the obstruction and cleaned the fan area. The photographs show the equipment and the work inside the sleeve.

Disconnected ducts under the house

At a separate Walnut Creek job, duct sections had pulled apart, sagged or torn in the crawl space. We repaired and supported the damaged runs, sealed the joints with mastic and added R-8 insulation to the repaired sections. The equipment itself had been working; the damaged ducts were losing its conditioned air.

Walnut Creek accepts building-permit applications through its online portal and no longer accepts paper or emailed applications. The City says the portal works best on a desktop or laptop, rather than a mobile device. Its list of work requiring a permit includes new, relocated and replacement HVAC systems.
