★★★★★
“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!”
★★★★★

GOOD TO KNOW
Generator Installation in San Francisco: questions, answered.
Do I need a permit for a generator connection?
Yes. Transfer switches and inlets are electrical work that requires a DBI permit. HAXX files it.
Is it safe to run a generator through a wall outlet?
No. Backfeeding through an outlet is dangerous to you and utility workers. An inlet with an interlock or transfer switch is the safe way.
Can I plug a generator into an outlet?
No. Back-feeding through an outlet is dangerous for you and for utility workers. Use an inlet with an interlock or a transfer switch.
What size generator do I need?
It depends on the circuits you want to keep powered. HAXX lists your critical loads and sizes the generator to them.
