Electrical Panel Upgrades & Circuit Replacements in Gulfport, MS
Your electrical panel is the control center of your home’s power system. When it becomes outdated, overloaded, or unsafe, it puts your entire property at risk. At Horton Heating, Air & Electrical, LLC, we provide professional electrical panel upgrades and circuit replacements for residential properties in Gulfport, MS. Whether you're dealing with flickering lights, tripping breakers, or planning a home addition, we ensure your electrical infrastructure is built to support modern demand—safely and efficiently.
We help homeowners stay compliant with current codes, improve energy management, and prepare their homes for today’s technology-driven lifestyle.
Electrical Panel Upgrades for Modern Homes
Many older Gulfport homes still operate with 100-amp or fuse-based electrical panels. These panels were not designed for the power requirements of modern homes with multiple appliances, HVAC systems, and electronics. We upgrade outdated panels to 150-amp, 200-amp, or higher-capacity systems that support increased circuit loads and future expansions.
During a panel upgrade, we remove the old panel, install a new breaker panel, reorganize circuit wiring, and test all connections for proper voltage and safety. We also label each circuit for easier identification and future troubleshooting.
Circuit Breaker Replacement Services
Circuit breakers protect your electrical system by shutting off power in the event of an overload or short circuit. Over time, these breakers can wear out or fail to trip as designed, increasing the risk of electrical fire or equipment damage.
We replace worn or faulty breakers with properly rated units that match your home's wiring and panel type. If your panel contains outdated or discontinued breakers (such as Zinsco or Federal Pacific), we recommend immediate evaluation and replacement due to known safety concerns.
Adding New Circuits for Expanding Power Needs
If you’re installing new appliances, converting a garage, or upgrading your HVAC system, you’ll likely need additional circuits. We assess your current panel’s load capacity and install dedicated breakers and branch circuits as needed to power specific equipment or zones.
Common requests include circuits for EV chargers, electric ranges, home offices, spas, and garage tools. We size each circuit correctly for the load and ensure all connections are safe, grounded, and properly labeled.
Signs It’s Time to Upgrade Your Electrical Panel
There are several signs your current panel may need to be replaced or upgraded:
Breakers trip frequently or won’t reset
Lights flicker or dim when appliances run
The panel emits heat, buzzing, or has a burning smell
You rely on multiple power strips due to lack of outlets
You’re adding a major appliance, HVAC system, or remodel
The home still uses fuses or outdated brands (e.g., Federal Pacific, Zinsco)
If you’re experiencing any of these issues, we recommend a panel inspection and load assessment to determine whether an upgrade is necessary.
Subpanel Installation for Expanding Electrical Systems
In cases where your main panel is full but the overall service is sufficient, we can install a subpanel to support additions like workshops, outdoor kitchens, or detached structures. Subpanels allow for flexible circuit management while avoiding the cost of a full service upgrade.
We connect the subpanel to the main system, add new breakers as needed, and distribute load safely across both units.
Whole-Home Safety Improvements
Panel upgrades often include other improvements that enhance safety and code compliance:
Arc-Fault Circuit Interrupters (AFCI): Required in many rooms to reduce the risk of fire from arcing
Ground-Fault Circuit Interrupters (GFCI): Installed in kitchens, bathrooms, and outdoor areas for shock protection
Surge Protection Devices (SPD): Optional additions that protect your electronics from power surges and lightning strikes
These components are installed in line with the upgraded panel to meet NEC and local Gulfport code standards.
Home Insurance and Real Estate Compliance
Upgrading your panel can also help satisfy insurance requirements and avoid delays during real estate transactions. Many insurers won’t issue new policies on homes with outdated or unsafe panels. We provide detailed documentation for all panel and circuit work to support your inspection, appraisal, or coverage process.
Permit Management and Code Compliance
All panel upgrades and circuit replacements are completed according to the National Electrical Code (NEC) and local building regulations in Gulfport, MS. We handle the entire permitting process, schedule inspections, and ensure every installation passes final approval before energizing the system.
Our licensed electricians take care to meet both the technical and legal requirements for electrical upgrades, delivering peace of mind with every project.
