Lighting Installation in San Antonio, TX
Interior and exterior lighting design and installation across the San Antonio metro.
Keil Electric San Antonio installs interior and exterior lighting across the San Antonio metro: recessed, under-cabinet, landscape, security, and fixture work. Master-licensed, TX #40645, (830) 214-8444.
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 nowLighting is where the climate here actually matters. Fixtures in San Antonio attics and on west-facing exteriors take a beating from heat and sun, and cheap fixtures fail fast. Choosing equipment rated for the conditions is most of the difference between a five-year install and a fifteen-year one.
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.
What's covered
5-year written warranty on lights, fixtures, ceiling fans. Parts and labor. Stays with the home and transfers to the next owner.
What is different about lighting installation in Texas.
Some of what we do for lighting installation 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 lighting installation 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.

Common questions for Lighting Installation in San Antonio, TX
Can recessed lights be installed in any ceiling?
Most ceilings allow recessed lighting, but joist spacing, insulation type, and fixture rating (IC vs non-IC) all matter. We confirm the ceiling type and verify clearance during the scoping visit.
Do you install homeowner-supplied light fixtures?
Yes. Customer-supplied fixtures are welcome. We do verify the fixture rating, the mounting support, and any required wiring changes before installation.
Does outdoor lighting need a different approach than interior?
Yes. Outdoor lighting requires wet- or damp-rated fixtures, weather-sealed wire connections, and GFCI-protected circuits. Landscape lighting often runs on low-voltage and uses a transformer to step down from line voltage.
Can ceiling fans be added where there is no fan box?
Often yes. We install fan-rated boxes that support the weight and movement of a ceiling fan. If the existing wiring is not rated for fan + light, we run the additional conductor as part of the install.
How are smart and dimmable lighting controls handled?
Both locations install smart switches and dimmers. We verify dimmer-bulb-fixture compatibility ahead of the install to avoid flicker, hum, or short bulb life.
Do you install smart lighting?
Yes. Smart switches, smart dimmers, scene controllers, motion-sensor switches, and platform-tied controls (Lutron Caseta, Leviton Decora Smart, Kasa, Hue) are all standard scope. Older homes often need a neutral wire pulled to the switch box first; we tell you the path before quoting.
Do you do ceiling fan installation?
Yes. Ceiling fan installation includes pulling a fan-rated box where the existing box is not rated, bracing to the joist, separate fan and light controls when wanted, and remote receiver setup. For homes with no overhead box, we pull a new circuit from the panel.
Will my LED bulbs dim properly with a new dimmer?
Sometimes. Not all LED bulbs dim cleanly on every dimmer. We verify bulb-and-dimmer compatibility before installing or recommend a tested combination.
Do you install can lights and recessed lighting?
Yes. Both retrofit (in finished ceilings) and new-construction recessed lighting are standard scope. We size for ceiling height, room layout, and bulb spec.
