The On-Time Promise fine print, in full

Wattsmith Electric works to the 2023 National Electrical Code and pulls the permit where one is required. How we handle permits, inspections and the workmanship guarantee is on our standards page. The license, the coverage in force and our federal registrations, including the certificate of insurance process for contractors, are on insurance and licensing.

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.

What EV charger installation in San Antonio includes

  • Level 2 240 volt charger installation, plug-in or hardwired
  • Dedicated circuit sized to the charger and the car
  • Load calculation to confirm panel capacity
  • Panel or sub-panel upgrade when capacity is short
  • Clean conduit runs across the garage or exterior
  • Permit and inspection where required

Signs you need this

  • You just bought an EV and are tired of the wall outlet trickle
  • Your charger trips the breaker or runs warm
  • You want faster charging without a new car
  • 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

Free estimate. We come look at the panel location, the charger, and the run, and give you a fixed price before anything starts.

  • Up to three options on a job, each a real way to do it, priced flat. You choose the scope.
  • The estimate is free. Nothing is owed until you approve the work.
  • The price you approve is the price you pay.

FAQ

EV Charger Installation questions

Straight answers. If you do not see yours, call us and ask.

Hardwired is cleaner and supports higher continuous output for most units. Plug-in is easier to swap later. We help you pick based on your car, your panel, and how fast you want to charge.
