MONTE SERENO DETAILSPanel upgrades in
Panel upgrades in
Monte Sereno.
Many Monte Sereno homes now add heat pumps, EV charging and pool or well equipment to panels sized for gas-heated houses. A load calculation shows where you stand.
01
Load calculation first
Sometimes a load-managed circuit or smart panel avoids a full service upgrade. HAXX shows the numbers before recommending one.
02
PG&E coordination
Service upgrades need PG&E to disconnect and reconnect. HAXX handles the paperwork and schedules the work around it.
03
Hillside and long runs
Detached garages, studios and equipment far from the main panel often need subpanels and properly sized feeders.

“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
Electrical Panel Upgrade in Monte Sereno: questions, answered.
Do I need a permit for a panel upgrade in Monte Sereno?
Yes. HAXX applies through the city's ePermits site, coordinates with PG&E and meets the inspector.
Are there rebates for electrical upgrades?
SVCE's home upgrades program lists rebates for electrical and efficiency improvements tied to electrification. Confirm current terms with SVCE.
Do I need 200 amps?
Not always. A load calculation shows whether your current service can carry the new appliances, sometimes with load management. HAXX recommends an upgrade only when the numbers require it.
How long does a panel upgrade take?
The panel swap itself is usually one day. Permits and utility scheduling for service upgrades can add several weeks, so plan early.
