Will my panel handle a charger?

We run a load calculation before we quote. If your panel is tight, we tell you and price the options, from load management to a service upgrade, before any work starts.

How fast will it charge?

A properly sized Level 2 circuit adds roughly 25 to 40 miles of range per hour depending on your car and charger. That is overnight full from empty for most drivers.

Why it does not pay to wait

Charging a modern EV on a wall outlet or an undersized circuit runs the wire hot for hours every night. Heat plus time is how insulation breaks down and connections fail. The wrong circuit behind a fast charger is a fire on a timer, and it voids the point of buying the car.

A fast home charger is only as good as the circuit behind it. Put a 48 amp charger on the wrong wire and you get nuisance trips, heat, and a fire risk. We size the circuit to the charger, confirm your panel can carry it, and run it clean.

Tesla, Ford, Rivian, or a hardwired unit off the shelf, it does not matter to us. We install it plumb, land it on the right breaker, and label it so the next electrician knows exactly what they are looking at.

Your panel has no obvious spare capacity

What you can check yourself first

Before you call, here is what you can safely check on your own. Even if you still call us, you will walk in knowing more than you did.

Find your panel and note the main breaker size and whether you have spare slots.
Measure roughly how far the panel is from where you park. Distance drives the cost more than anything.
Check what your car and charger actually pull. A 48 amp charger needs far more than a 32 amp one.
Decide plug-in or hardwired if you can. We will confirm the right call on the walkthrough.

Straight pricing

Most installs are quoted flat once we know the panel location, the charger, and the run. Long runs and panel work are priced up front, never after.

Three options on every job, priced flat. You choose the scope.
The diagnostic fee applies toward the work performed.
The price you approve is the price you pay.
