FAQs
What areas do you serve?
Haxx is centered in San Jose and serves Santa Clara, San Mateo and nearby South Bay communities. Coverage can vary by project type and scope, so it is worth confirming your address when you book.
Are you licensed and insured?
Yes. Haxx represents its work under California contractor license 1081990 and describes itself as licensed, bonded and insured, with electrical work carried out under a C-10 contractor framework.
Do you work on both residential and commercial projects?
Yes. Haxx serves homeowners, rental properties, property managers, offices, retail spaces and other light commercial environments for both electrical and HVAC work.
How do I know if I need a main panel upgrade?
Common signals include an outdated panel, frequent breaker trips, flickering lights under load, burning smells, visible heat around the panel, or major new electrical loads such as EV chargers and HVAC upgrades.
Do I need a permit for EV charger installation?
In most Bay Area cities, EV charger installations typically require permit and inspection involvement. Haxx frames professional installation around code compliance and dedicated-circuit planning for safer long-term use.
Do you perform electrical load studies?
Yes. Haxx offers 30-day load studies under NEC 220.87 for service capacity review, larger commercial loads and certain high-capacity residential projects, with documentation suited to PG&E and City of San Jose review.
Should I repair or replace my HVAC system?
That depends on the age of the system, how often it is failing, the cost of the current repair and whether the equipment still delivers dependable comfort. A diagnostic visit is usually the cleanest way to decide.
What other services does Haxx offer?
Beyond electrical and HVAC, Haxx handles appliance repair for refrigerators, ovens, gas ranges, electric stoves, cooktops, dishwashers, dryers and washers, plus solar installation and solar panel cleaning.
