★★★★★
“Recently, my dishwasher stopped working, and they discovered it was actually an outlet issue. Not only did they diagnose it quickly, but they also fixed the outlet—saving me from calling an electrician. Reliable, professional, and skilled at handling both appliances and electrical issues.”
★★★★★
“I purchased a couple of ceiling fans and was reluctant due to how old my house was with old wiring so I wanted someone professional and trustworthy. They have been both!”
★★★★★
“Prompt and professional - they helped run a new thermostat wire through a wall and crawl space.”

GOOD TO KNOW
Electrical Panel Upgrade in Colma: questions, answered.
Do I need a permit for a panel upgrade in Colma?
Yes. Panel work is permitted through the Town of Colma Building Division and must pass inspection. HAXX handles both.
How long will the power be off?
Usually about a working day for a panel swap, depending on PG&E scheduling.
Do I need 200 amps?
Not always. A load calculation shows whether your current service can carry the new appliances, sometimes with load management. HAXX recommends an upgrade only when the numbers require it.
How long does a panel upgrade take?
The panel swap itself is usually one day. Permits and utility scheduling for service upgrades can add several weeks, so plan early.
