Direct answer

Keil Electric San Antonio handles commercial electrical work across the San Antonio metro for offices, retail, restaurants, medical, and light industrial: tenant improvements, service and panel upgrades, lighting retrofits, dedicated circuits, and code corrections. Master-licensed, TX #40645, (830) 214-8444.

  Response time

San Antonio: Most days we're already in the area. Same-day appointments when capacity allows. After-hours emergencies dispatched when a licensed electrician is available, a real person at the local shop answers and tells you the ETA on the call.

Call now

Commercial work in San Antonio runs on two clocks residential does not: your business hours and the City’s inspection schedule. A tenant improvement in a retail space off Loop 1604, a panel upgrade for a restaurant on the St. Mary’s strip, or a lighting retrofit in a south-side warehouse all have to be sequenced so the space opens on time and passes a commercial inspection through Development Services. We coordinate the CPS Energy service work, pull the commercial permit, and schedule the disruptive parts after hours where we can, because a dark sales floor costs more than the electrical.

  Permits

Permits and inspections

Not every job requires a permit. When the local AHJ requires one, we pull it, schedule the inspection, and stay with the job until it passes. No paperwork on you.

  Warranty

What's covered

Written warranty: 5-year on outlets, fixtures, and EV chargers; 10-year on wire and breakers; lifetime on panelboxes and surge protection. Parts and labor. Transfers with the home.

01 - TX SPECIFIC · SAN ANTONIO METRO

What is different about commercial electrician services in Texas.

Some of what we do for commercial electrician services is shaped by the codes and conditions specific to Texas. Here is what tends to differ versus other states.

Code adoption in Texas

Texas adopts the National Electrical Code at the state level through the Texas Department of Licensing and Regulation, with most cities in the San Antonio metro adopting the most recent NEC cycle within a year or two of publication. Schertz, New Braunfels, Cibolo, and the other cities we cover each maintain their own permitting offices with slightly different inspection scheduling and form workflows. We track which cycle each AHJ in our coverage area is currently enforcing, so the scope we write for a job in Schertz is current to that city, not just current to "Texas." When a project crosses jurisdictions or sits in unincorporated county, we route the permit through the correct authority and tell you upfront which inspection cadence applies.

Hot-climate considerations

Summers across the San Antonio metro run long and hot, and that affects commercial electrician services in ways that are easy to underestimate. Panels mounted on west-facing exterior walls run hotter all afternoon. Attic-mounted equipment derates per code because ambient attic temperatures regularly clear 130°F. AC compressors pull near-rated current for hours at a stretch through July and August, which puts more thermal cycling on terminations than the same equipment would see in a milder climate. We size conductors and breakers with that summer load profile in mind, not just the nameplate minimum. On older homes we look closely at terminations that may have loosened from years of heat cycling, those are a common cause of intermittent issues that get misdiagnosed elsewhere.

Severe weather and storm response

The metro sees thunderstorm hail, the occasional derecho, and the post-storm spike in generator and surge-protection demand that comes with each event. We keep enough surge-protection inventory at the shop to swap out a damaged whole-home unit same-day after a strike, and we know which generator and transfer-switch SKUs are realistic to source quickly when the supply chain tightens after a regional event. After the 2021 winter storm we also got a lot more careful about which loads customers actually need on backup, versus which loads end up on the generator only because nobody asked the question at install time.

03 - WHO TO HIRE

Why hiring a licensed electrician matters.

For commercial electrician services, here's the honest comparison. We'd tell you the same thing if we weren't trying to win the job.

Keil Electric

A licensed electrician

Licensed electrician walks every job. Veteran-owned, family-run.
Permits pulled and inspections coordinated when required by the AHJ
5/10-year + lifetime warranty in writing. Parts and labor. Transfers with the home.
Fully insured + workers' comp on every crew
The price you sign is the price you pay
A handyman

Unlicensed for electrical

No state electrical license. Can do simple swaps but not panel work, rewires, or service upgrades.
No permits. Work won't pass inspection if the city audits it later.
No structured warranty. "Call me if something breaks" isn't enforceable.
If something they did causes a fire, your homeowner's insurance can deny the claim.
Cash discount may show up on the invoice.
DIY

Doing it yourself

Cheap, but only if everything goes right. Most electrical work involves load calc, code, and permitting.
A failed inspection means redoing the work. Selling the home later, the buyer's inspector flags it.
No warranty if something fails. Replacement is on you.
Live wiring is a real safety hazard. Most fatal home electrical accidents are DIY.
If you know what you're doing, fine. If you don't, call us first.

Common questions for Commercial Electrician Services in San Antonio, TX

What commercial scopes does Keil Electric handle?

Tenant improvements, light commercial buildouts, retail electrical service, office electrical, multifamily building service, restaurant electrical, and ongoing facility maintenance contracts.

Do you coordinate with general contractors and project managers?

Yes. Commercial projects have a named contact on our side who coordinates scheduling, scope changes, and inspections with the GC, project manager, or facility lead.

Can you support after-hours or off-hours work?

Yes, when the project requires it. Tenant retail and office work often runs after hours; we schedule the work to match the building's operating window.

Do you handle ongoing maintenance contracts?

Both locations offer recurring electrical maintenance for property managers and facility owners. Cadence and scope are set per the property's needs.

How do commercial requests work versus residential?

Commercial requests use the named-contact form on each location page, not the standard service request flow. Response goes through the project lead rather than residential dispatch.
