EV Charger Installation · Hennessey, OK · Answered 24/7
Level 2 home charging and Tesla Wall Connector installs — sized to your panel, run where you actually park, and done in one visit in most homes.
Hennessey customers call us for ev charger installation more than almost anything else. Here is how we approach it.
We run the load calculation on your existing service before promising anything. That step is where most bad EV installs go wrong.
Cable length, parking position and future second car all factor into where the unit lands on the wall.
Correct conductor size for a continuous load, proper breaker, and a clean run rather than surface conduit across the front of the garage.
We energize, pair the unit and watch a real charging session start before leaving.
“Buying a 1962 house and wanted to know what I was walking into. Got a written report with photos, sorted by urgency, with prices. Used it to negotiate the sale price.”
Erin V.Hennessey, OK“Landscape lighting front and back, on a timer. They came back after dark to aim the fixtures properly, which I did not expect.”
Cheryl D.Hennessey, OK“We added a bathroom and they handled the circuits, GFCI, fan and lighting. Passed inspection first try.”
Hollis M.Hennessey, OKMost installs are a half day when the panel has capacity and the run is reasonable. Long runs, panel upgrades or detached garages add time and we quote that up front.
Not always. Many 100 amp services can carry a 40A charger with a load calculation or a load management device. We check rather than assume.
Yes. Customer-supplied units are normal, and we will tell you before install day if the model you bought fits the circuit we are proposing.
Hardwired at 48A charges faster and is generally the better long-term install. A 14-50 outlet is fine at 40A and lets you unplug and take the unit if you move.
Yes, all of Hennessey and the surrounding area. Call (866) 651-5242 and we will confirm the arrival window for your address.
Urgent work gets same-day attention where we have capacity, and planned work is usually scheduled within the week. You get a firm date rather than a maybe.
