★★★★★
“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
Generator Installation in Fairfax: questions, answered.
Can I plug a generator into my house?
Only through a transfer switch or a listed inlet with an interlock. HAXX installs both.
What size generator does a Fairfax home need?
It depends on the circuits you want running. HAXX sizes the generator from a load calculation of those circuits.
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.
