FAQs
Do I need a permit for an EV charger or panel upgrade in Greenwich?
Yes. Most Level 2 chargers and all service/panel upgrades require an electrical permit and inspection. Chestnut Electric handles the paperwork and coordinates the inspection.
How much does a home EV charger installation typically cost?
Basic installs can start under $1,000 when the panel has capacity and the run is short; more complex installs (longer wire runs, panel upgrades, trenching) can run $1,500–$3,000+. We provide firm, upfront pricing after a quick assessment.
Why do my breakers trip or lights flicker?
Common causes include overloaded circuits, failing breakers, loose neutrals, or aging wiring. Our diagnostic pinpoints the root cause and we present code-compliant fixes with clear pricing.
What size electrical panel do I need?
Many modern homes benefit from 200A service—especially with renovations, EVs, or large appliances. We’ll calculate your actual load and recommend the right upgrade.
Can you help lower my electric bill?
Yes—LED retrofits, smart controls, and power-saving upgrades often reduce usage. We can identify the best ROI options for your home or business.
Do you offer maintenance plans?
We provide routine safety inspections and preventive maintenance to catch issues before they become costly repairs or cause downtime.
