Electrical Panel Upgrade in Torrance
A panel upgrade replaces your main service panel with one that has more amperage and breaker space, usually because you’re adding equipment that draws more power than the original panel was built for. In Torrance, converting to central HVAC is one of the most common reasons we upgrade a panel still running on its original 1950s-60s 100A service.

Why HVAC Conversions Drive Upgrades Here
Many Torrance homes were built before central air conditioning was standard, and their original 100A panels weren’t sized for that additional continuous load. Adding a modern central HVAC system on top of everything else usually pushes past what a 100A panel can safely support.
That’s a capacity issue tied to a specific equipment change, not a sign the existing panel is unsafe or failing on its own.
What a Panel Upgrade Involves
- Load calculation confirming the HVAC conversion requires more capacity
- City permit filing and inspection scheduling
- Replacement of the original service mast and weatherhead
- Dual ground rod installation and copper water line bonding
- Re-routing of branch circuits with modern AFCI/GFCI breakers
For the general upgrade process, see our Electrical Panel Upgrade service page. This page focuses specifically on what that looks like in Torrance.
FOR HOMEOWNERS
A Recent Torrance Panel Upgrade: What We Did
An older property in Torrance operating on a 100A panel required an upgrade to 200A to support a central HVAC conversion. We pulled city permits and replaced the original main panel with a modern 200A outdoor NEMA 3R enclosure.
The work included replacing the original service mast and weatherhead, installing dual ground rods and bonding the copper water lines, and re-routing branch circuits with modern AFCI/GFCI breakers.
The upgraded system passed city building inspection on the first visit, clearing the way for the HVAC conversion to move forward without any capacity concerns.
If you just want to confirm whether your current panel can handle a new HVAC system before committing to a full upgrade, our Electrical Safety Inspection in Torrance page covers that capacity check.

Common Questions About Panel Upgrades in Torrance
Do I need a panel upgrade to add central HVAC?
Often yes, if your home still has its original 100A panel from the 1950s-60s, an HVAC conversion usually requires more capacity than that panel has left to give.
How long does a panel upgrade take?
Most residential upgrades take one to two days including the permitted city inspection.
Will I lose power during the upgrade?
Yes, briefly, typically a few hours while the old panel is disconnected and the new one is installed and inspected.
Do I need a permit for a panel upgrade?
Yes, panel upgrades always require a city permit and inspection, which we handle as part of the project.
