Panel upgrades, EV charger circuits and heat pump wiring for San Rafael homes, from our San Rafael office.
Looking for an electrician in San Rafael to get a home ready for a heat pump or an EV charger? Start with the panel. Every new appliance adds load, and an older panel may have little room left. Our San Rafael office at 710 C St, Suite 211 handles electrical panel upgrades and replacement for homes across town.
We size the job before we price it. We look at what the panel carries now, what you plan to add and whether a dedicated circuit is enough or the panel itself needs replacing. We explain the options in plain terms and leave the decision to you. For EV charger installation in San Rafael, that means a charger circuit the panel can support.
The same company installs heat pumps and heat pump water heaters, so the circuits for them are planned with the equipment. Installations come with a free estimate, and financing is available. Senior and veteran discounts apply. Same-day service available in San Rafael. Call to book.
Heat pumps, EV chargers and electric water heaters all draw on the same panel. We check its capacity before anything is installed.
It depends on what the home runs today and what you plan to add. A heat pump, EV charger or electric water heater each adds load. We look at the panel’s rating and open spaces, add up the new equipment and recommend whether the current panel is enough. A larger panel is not always required.
We confirm where the charger will mount, check the panel for spare capacity and run a dedicated circuit to that spot. Depending on the result, the job may be a new breaker and circuit, or a panel upgrade first. You get a free estimate on the installation before any work starts, and financing is available.
Yes. We install water heaters, including heat pump water heaters, and we handle the circuit they need. A heat pump water heater often needs its own circuit, so we check the panel for room first. One contractor covers the plumbing connections and the wiring, which keeps the schedule simple.
Add a circuit when the panel has open spaces and enough capacity for the new load. Upgrade the panel when it is full, when breakers trip under normal use, or when you are adding several large loads at once, such as a heat pump and an EV charger. We tell you which applies after we look at the panel.
