Sunnyvale's housing ranges from Heritage District cottages to 1960s Eichlers and ranch homes, plus newer townhomes. Each brings its own wiring issues.
Post-and-beam ceilings leave little space for wiring. HAXX plans lighting and new circuits around the exposed structure.
Ungrounded circuits and too few kitchen circuits are common. New appliances often need dedicated circuits.
HAXX applies for City of Sunnyvale electrical permits when the work requires one and meets the inspector.

“Prompt and professional - they helped run a new thermostat wire through a wall and crawl space.”
“I told him that the lights in my living room had been flickering for a while and asked if he could take a quick look. Instead of brushing it off, he immediately went to the main panel, asked a few questions, and then checked my subpanel in the garage.”
