★★★★★
“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.”
★★★★★
“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.”

GOOD TO KNOW
Generator Installation in Sunnyvale: questions, answered.
Is it safe to plug a generator into my house?
Only through a transfer switch or a listed inlet and interlock. HAXX installs both.
What size generator do I need?
It depends on what you want to run. HAXX sizes it from a load calculation.
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.
