Electrical Service Upgrade

Electrical Service Upgrade you can count on

A service upgrade is not the same job as a panel swap, even though the two often happen together. Upgrading the service means changing how much power the utility delivers to your house — the conductors, the meter socket, the service entrance and, on an overhead service, usually the mast as well. The panel is the last piece, not the whole job.

Most of the upgrades we do on the Central Coast come down to one of three things: an EV that needs a real charger instead of a wall outlet, a heat pump replacing gas heat, or an ADU that has to be fed from the main service. Each of those is a load that older 60A and 100A services were never designed to carry alongside everything else in the house.

The honest version of this conversation starts with arithmetic. We run the calculation, tell you what your existing service can and cannot support, and if it turns out you do not need an upgrade, we will say so. Selling a service upgrade to someone who needs a dedicated circuit is an easy way to make one sale and lose a neighbour.

What we handle

• Service upgrades to 200A and 400A
• Meter main and service entrance replacement
• Load calculations to right-size your service
• Utility and permit coordination start to finish

Signs it is time to call

You still have a 60A or 100A service

Common in Central Coast homes built before the mid-seventies. Perfectly adequate for the house as it was built, and increasingly tight for the way houses are used now.

Lights dim when a large appliance starts

A noticeable dip when the AC compressor or the well pump kicks in points at voltage drop and a service working near its limit.

An EV charger quote came back with conditions

If someone has told you a Level 2 charger needs a load-management device or cannot be installed at all, the service is the reason.

You are adding an ADU, shop or well

Any of these has to be fed and calculated. On rural North County properties a well pump alone can reshape the whole calculation.

How the job runs

1. Load calculation against your actual plansExisting load plus everything you intend to add, worked to the code method rather than a rule of thumb. You see the numbers.
2. Service entrance assessmentMast, weatherhead, meter socket, conductors, grounding electrode system and bonding. This is where most of the real cost sits, and it is why we look before quoting.
3. Permit and PG&E coordinationService changes involve the utility as well as the building department. We file both and schedule the work so the pieces line up.
4. Upgrade dayNew service entrance and meter equipment, new panel sized to the calculation, grounding and bonding to current code, circuits landed and labeled.
5. Inspection and releaseInspector signs off, utility releases the meter, you get the paperwork.

What moves the price

We do not publish a flat number for work we have not looked at — a quote made from a web page is a guess, and guesses get corrected on invoice day. These are the things that genuinely change what your job costs:

• Overhead versus underground service — an underground run means trenching, conduit and considerably more work
• The distance from the utility connection point to the meter, which on rural parcels can be substantial
• Whether the mast, weatherhead and meter socket can be reused or must be replaced
• Target service size: 200A is the common answer, 400A is a different class of equipment
• Grounding electrode work, which older homes almost always need
• Any utility-side work PG&E has to schedule on their own timeline
• Permit fees and inspection requirements for your jurisdiction

The panel is rarely the expensive part. The service entrance and the trenching are, which is why an upgrade on a compact in-town lot and the same upgrade on an acreage parcel are not comparable jobs.

What this means on the Central Coast

North County parcels around Atascadero, Templeton, Creston and Santa Margarita often sit a long way from the road, and the distance between the utility connection and the house is frequently the single biggest line on the estimate. It is also the reason we would rather drive out and look than quote from a phone call. If you are on a well, tell us — well pumps have starting characteristics that belong in the calculation from the beginning.
