“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
EV Charger Installation in Napa: questions, answered.
Do I need a permit for an EV charger in Napa?
Yes. The City of Napa requires a building permit with its EV charging checklist, plans and a load calculation. HAXX prepares the submittal.
Can you install a NEMA 14-50 outlet instead of a hardwired charger?
Yes. HAXX installs both and will explain the tradeoffs for your car and panel.
How fast will a Level 2 charger charge my car?
Most homes install a 40 to 60 amp circuit, which adds roughly 25 to 45 miles of range per hour depending on the car. Panel capacity sets the limit.
Do I need a panel upgrade for an EV charger?
Often not. A load calculation and a right-sized circuit or load-management charger can avoid it.
