Wiring & Installations We Provide
Services for Smart Systems (Wiring Only)
Treviño Repairs delivers code-compliant wiring and clean mounting so your smart hardware has solid power and signaling from day one. We verify line/load and neutral at switch boxes, add C-wires for thermostats, right-size doorbell transformers/chimes, and plan PoE/low-voltage runs for cameras and hubs. Outdoors, we use WR/TR devices with in-use covers and ensure required GFCI/AFCI protection. On every job we manage box-fill, grounding, and low-/high-voltage separation, then label and test (voltage, continuity, PoE budget) and leave tidy cable management and a simple handoff so you—or your IT/security provider—can handle app setup later.
We install & wire:
- Smart switches/dimmers (LED-compatible), smart plugs, occupancy/vacancy sensors
- Thermostats with C-wire add or adapter, clean baseplate installs
- Video doorbells (transformer/chime kit upgrades), doorbell wiring repairs
- Cameras (PoE/Wi-Fi): PoE injector/switch runs, low-voltage cabling, mounting
- Smart locks/keypads power/wiring prep and strike wiring (where applicable)
- Hubs/bridges outlets and structured media panels; outlet adds for gear
Network & code essentials (as applicable):
- PoE budget planning and low-voltage separation
- TR/WR devices outdoors with in-use covers; GFCI/AFCI protection where required
- Labeling, voltage/continuity checks, and neat cable management
Wiring Basics for Reliable Smart Gear
Smart hardware depends on the right electrical prerequisites: a neutral for most switches, dimmers matched to LED driver type to prevent flicker, a properly sized doorbell transformer/chime for video units, and sufficient PoE power or dedicated low-voltage for cameras. Outdoors, use WR + in-use covers; keep low-voltage separated from high-voltage; and ensure boxes have safe box-fill and grounding. We handle the wiring and mounting so your devices have clean power and stable connections—then you (or your provider) can complete app pairing and automations.
Know the Warning Signs in the Rio Grande Valley
When You Need Wiring Help
LEDs flicker on new smart dimmers, switches need a neutral that isn’t in the box, video doorbells hum or drop when pressed (undersized transformer), cameras reboot or go offline (low PoE budget or voltage drop), chimes don’t ring after a doorbell swap, or you’re missing outlets where hubs/NVRs live. These point to wiring/power issues we can fix—so your system is ready for configuration afterward.

Will call again if I have other electrical problems.Posted on Jennifer CastilloTrustindex verifies that the original source of the review is Google. Great Service: We had a leak and couldn’t figure out where it was coming from. Eduardo took his time to find the source, kept me updated throughout the process, and finally discovered it was an AC leak. Just last week, we had paid another company to fix the same issue, but they didn’t do the job correctly. Eduardo explained everything clearly, offered to correct the problem, and even charged less than what we had previously paid the other company. Once he identified the leak, he made sure it was completely taken care of. I called today, and they arrived in less than an hour—excellent service! Eduardo was the best, and I highly recommend him company.Posted on JoAnn BreauxTrustindex verifies that the original source of the review is Google. Great service, super fast and convenient.

Smart System Questions, Answered
Straightforward answers before you book—symptoms, costs, fixes.
Do you set up apps, accounts, or automations?
No—we provide wiring, power, and mounting and confirm devices power on. App pairing, cloud storage, and automations are handled by you or your provider.
Can you add a C-wire for my thermostat?
Yes. We can pull a new conductor or install a compatible adapter so the thermostat has stable power.
My smart switch won’t work—no neutral in the box. Can you fix that?
Often yes. We can provide a neutral via approved methods or recommend no-neutral devices if appropriate.
My video doorbell is weak or the chime cuts out—why?
Usually the transformer/chime is undersized or wired incorrectly. We can upgrade the transformer and correct wiring so it’s ready for configuration.
Do you prewire PoE for cameras and install the NVR?
We can prewire PoE, mount cameras, and provide outlets/rack space. We power-test lines, but NVR setup, storage, and user accounts are up to you.
