Yes. We coordinate all permits and inspections end-to-end. This includes city/county permits for electrical work, generator installations, EV chargers, and panel upgrades. Inspection scheduling is included.

Are there EV charger rebates available?

Yes — utility programs vary by provider. PSE offers up to $1,000, Seattle City Light offers $500-1,000, Tacoma Power offers rebates, and Snohomish PUD has programs. We check eligibility during booking and handle paperwork.

How long does an EV charger installation take?

Most Level 2 charger installs take 1-2 days. If a panel upgrade is needed, allow 3-5 days total. Permitting adds 1-2 weeks but we coordinate this while ordering equipment.

What size generator do I need?

Typical homes need 16-22 kW for essential circuits (fridge, lights, heat), or 22-26 kW for whole-home backup. We perform load calculations during site visits to size correctly. Generac Guardian Series 10-26 kW are most common.

What is the typical cost to install a Level 2 EV charger in Western Washington?

Most standard installs fall between $1,200-2,500 depending on panel capacity, run length, and permitting. Sound Power provides a written scope and pulls permits. EV Charger: $1,200-2,500 installed. Panel Upgrade: $2,500-5,000. Standby Generator: $8,000-15,000 installed.

Do you work with solar installers?

Yes. We handle the electrical wiring, interconnection, and utility coordination for solar PV systems. We partner with solar panel installers or work with your chosen company. Battery backup (Enphase IQ) integration available.

What brands do you install?

EV Chargers: Tesla Wall Connector, ChargePoint, JuiceBox, Grizzl-E, Emporia. Generators: Generac (Authorized Dealer), Kohler. Smart Panels: Span, Lumin. Monitoring: Emporia Vue, Sense. Battery: Enphase IQ Battery systems.

Do you offer financing?

Yes. We work with financing partners for projects over $3,000. 0% APR for 12-18 months often available (subject to credit approval). Ask about options when scheduling.

What is your response time?

Within 1 business day for quotes and scheduling. Same-day emergency service available for critical issues. Most installations scheduled within 1-2 weeks of estimate approval.

Do you provide warranties?

Yes. Our workmanship is guaranteed for 1 year. Equipment warranties vary: Generac generators (5 years), EV chargers (3 years typical), Enphase batteries (10-15 years). We facilitate all warranty claims.

Who installs and services Generac home standby generators in the Puget Sound region?

Sound Power provides Generac standby generator solutions including maintenance/service and backup power planning for homes and small businesses across the Puget Sound area.

What does generator maintenance include?

Typical maintenance includes visual inspection, oil/filter service intervals (per model), battery testing, exercise cycle verification, load/transfer verification, and a reliability report with recommendations.

Do I need a transfer switch for a home generator?

Yes—safe backup power requires proper transfer equipment to prevent backfeed and to manage loads. Sound Power can evaluate the best transfer approach for your home.

Can my existing panel handle an EV charger?

Sometimes yes, sometimes absolutely not. Sound Power checks panel size, existing loads, and code requirements. In some cases, a smart load management solution or a panel upgrade is the right move.

How long does an EV charger installation take?

Most straightforward EV charger installs take about a day. More complex projects (panel upgrades, long conduit runs, or combined EV + backup power upgrades) may take multiple days.

Can you install a Tesla Wall Connector or charger I already bought?

Yes. Whether you purchased direct from Tesla, from another EV brand, Costco, or online, Sound Power can install the unit, verify settings, and ensure your home wiring is correctly matched to its requirements. We work with all major EV charger brands including Tesla Wall Connector, ChargePoint, JuiceBox, and Grizzl-E.

Is Level 2 charging worth it vs a 120V outlet?

For real-world Puget Sound commutes, Level 2 is the difference between 'EV as a toy' and 'EV as your main car.' A 120V outlet provides 3-5 miles of range per hour, while Level 2 chargers provide 25-40 miles of range per hour.

Do you work with all EV brands?

Yes! Sound Power installs charging systems for all EV makes and models including Tesla (Model 3, Y, S, X, Cybertruck), Ford (Mustang Mach-E, F-150 Lightning), Chevrolet Bolt, Rivian R1T/R1S, Hyundai/Kia EVs, Nissan Leaf, VW ID.4, and more.

Do you serve all of Normandy Park?

Yes. We cover Normandy Park and adjacent neighborhoods near Burien, SeaTac, and Des Moines.

Do you pull permits for Normandy Park projects?

Yes. Sound Power pulls permits and schedules inspections, then meets the inspector on site.

Typical cost for a Level 2 EV charger install in Normandy Park?

Most standard installs fall between $1,200–$2,500 depending on panel capacity, run length, and permitting.
