Safe, Code-Compliant Power for the Rio Grande Valley
Electrical Panel Upgrades & Repairs
Older or undersized panels, frequent breaker trips, flickering lights, warm panel covers, or plans to add EV chargers, HVAC, or kitchen circuits all point to panel work. Treviño Repairs evaluates your load, capacity, grounding/bonding, and available spaces, then completes clean, code-compliant repairs or upgrades (100A/150A/200A+). We coordinate permits and utility shutdowns when required, label circuits, balance loads, and leave a neat finish for your home or business.
More Capacity. More Protection. Done Right.
Services for Panel Upgrades & Repairs
Treviño Repairs plans and executes panel work with safety, clarity, and full code compliance. We start with a load calculation and capacity review to decide whether a targeted repair, subpanel, or full upgrade makes sense—accounting for future circuits like EVs, HVAC, or remodels. On site, we protect the workspace, handle permits and utility coordination when required, correct wiring practices (neutral/ground separation in subpanels, proper bonding/grounding, no double-lugged neutrals, torque to spec), and add modern protection—AFCI/GFCI where applicable and whole-home surge. We balance loads, label circuits neatly, verify voltage and breaker function, and re-energize with a clean, inspection-ready finish for your Rio Grande Valley property.
We install & service:
- Main service panel upgrades (100A/150A/200A/400A)
- Subpanels for additions, shops, and ADUs
- Breaker replacements, AFCI/GFCI/dual-function breakers
- Whole-home surge protection
- Meter base, service mast, and service disconnect replacements
- Grounding & bonding upgrades (ground rods, water/gas bond)
- Bus bar corrosion/heat-damage remediation
- Panel relocation/rewire and clean labeling
- Replacement of obsolete/unsafe gear (e.g., FPE, Zinsco)
- New dedicated circuits (EV charger, range, dryer, HVAC)
Code items & best practices (as applicable):
- Permits and utility coordination when required
- Working-space clearances and panel height compliance
- Neutral/ground separation in subpanels; bonding screw checks
- No double-lugged neutrals; torque to manufacturer specs
- Arc-fault/ground-fault protection where required by current standards
Panel Repair vs. Panel Upgrade
Repair addresses specific faults—burned lugs, a failed main breaker, loose terminations, corroded bus bars, or mislabeled/double-lugged circuits. We correct the defect, restore safe operation, and verify torque, terminations, and protection.
Upgrade is the smarter long-term move when capacity is maxed out, multiple tandem (“cheater”) breakers are filling spaces, the panel is obsolete/damaged, or you’re adding high-demand loads (EV, HVAC, remodel). We perform a load calculation, size the service, update grounding/bonding, and install modern protection and surge suppression for reliability.
Know the Warning Signs in the Rio Grande Valley
When to Service or Upgrade Your Panel
Frequent breaker trips, lights dimming when big appliances start, warm or buzzing panels, scorch marks or a burnt odor, limited spaces filled with tandem breakers, rust/corrosion, aluminum terminations that need attention, or legacy gear (like Federal Pacific or Zinsco) are strong indicators your panel needs professional service. Planning an addition, EV charger, or new HVAC is another good time to review capacity and protection.

What Our Customers Are Saying
Panel Upgrades & Repair Questions, Answered
Straightforward answers before you book—symptoms, costs, fixes.
Do I really need 200 amps?
Not always. We size the service to your actual load and future plans (EV, HVAC, remodel). Sometimes a subpanel or circuit reorganization is enough.
How long will the power be off?
Like-for-like repairs can be hours; full upgrades typically require a scheduled shutdown and inspection window. We’ll give a clear plan and timeline.
Will you pull permits and coordinate with the utility?
Yes, when required. We handle permits, utility coordination, and inspections so the job meets current standards.
Are Federal Pacific or Zinsco panels unsafe?
Many inspectors flag them due to known breaker/bus issues. If you have one, we’ll assess condition and provide upgrade options.
Do I need AFCI/GFCI breakers everywhere now?
Current standards require these protections in specific areas. We’ll review what applies to your home and include compliant breakers in the scope.
