Harmony Electric delivers full-service electrical installation for new construction projects across Seattle, Bellevue, Kirkland, Redmond, Issaquah, Sammamish, Newcastle, Renton, and surrounding areas. We work directly with builders, general contractors, and developers to install reliable, code-compliant electrical systems designed for long-term performance. From early planning to final inspection, our work is built to keep projects on schedule and pass inspections without delays. Our expertise also extends into residential electrical services and commercial electrical projects, allowing us to support builds of all sizes.

Our team handles every phase of electrical work for new residential builds, custom homes, multi-unit developments, and accessory dwelling units. We design systems that support modern electrical demand, future expansion, and energy efficiency. Many new builds today also include infrastructure for EV charger installation and advanced electrical upgrades such as panel upgrades. Our complete service includes:

• Full electrical system design and layout planning
• Load calculations and proper service sizing
• Temporary construction power installation
• Rough-in wiring for walls, ceilings, and foundations
• Main service panel installation (100A, 200A, 400A)
• Subpanel installation and circuit distribution
• EV charger pre-wire and dedicated circuits
• Smart home and low-voltage pre-wiring
• Interior and exterior lighting systems
• Switch, outlet, and device installation
• Final system testing and inspection readiness

New construction electrical systems must be designed with durability, safety, and future expansion in mind. Harmony Electric installs systems that are built to handle modern electrical loads, including electric vehicles, smart home systems, and increased energy demands. Planning for EV charging infrastructure and future panel capacity upgrades ensures your property remains adaptable for years to come.

We follow a structured, step-by-step process to ensure efficiency, organization, and consistent quality throughout every stage of construction. Our experience with electrical troubleshooting and repairs also helps us design systems that avoid common issues before they happen.

1. Plan Review & Coordination — We review blueprints and coordinate with contractors to ensure an efficient and accurate electrical layout
2. Load Calculation & System Design — Electrical systems are properly sized for current and future expansion needs
3. Rough-In Wiring — Wiring is installed cleanly before insulation and drywall phases
4. Panel & Service Installation — Main service equipment and subpanels are installed to code, often incorporating modern panel solutions
5. Trim & Finish Work — Devices, fixtures, switches, and outlets are installed with precision, including custom lighting installations
6. Final Inspection Preparation — Systems are fully checked to ensure smooth inspection approval

Harmony Electric understands the demands of construction schedules, job site coordination, and project timelines. We work closely with general contractors, builders, and developers to ensure seamless execution from start to finish. Our combined experience across commercial builds and residential construction allows us to adapt to any project scope.

• Consistent communication throughout the project
• Reliable scheduling to avoid delays
• Clean and organized job site practices
• Code-compliant installations that pass inspection

Every new construction project in Seattle and Eastside requires properly sized electrical service.

We install and design:

• 100 amp electrical panels for smaller builds and ADUs
• 200 amp panels for standard residential homes
• 400 amp systems for larger homes and multi-unit properties

We ensure your electrical panel is sized correctly for:

• EV charging in Seattle homes
• HVAC systems
• Kitchen appliance loads
• Future electrical expansion

Many Bellevue and Kirkland new builds now require EV-ready panel planning, which we incorporate into every design.

Modern new construction projects in Seattle, Bellevue, and Kirkland increasingly require EV charging infrastructure.

We provide:

• EV charger pre-wiring during construction
• Dedicated EV circuits for future installation
• Load calculations for Tesla and universal EV chargers
• Panel capacity planning for EV-ready homes

This ensures your new home is fully prepared for electric vehicle adoption without future rewiring or upgrades.
