How much does home standby generator repair typically cost?

Generator repair cost varies by the fault, parts, and labor time. We confirm pricing after an on-site diagnostic. Castle Electric repairs and maintains Generac units only, using genuine Generac parts and factory-approved procedures. Common items that affect price include transfer switch issues, fuel pressure problems, battery replacement, wiring faults, and control panel sensors. Annual or semi-annual maintenance can reduce repair costs and protect your warranty. We serve Greater Boston, including Quincy and Newton, with licensed, insured electricians and 24/7 emergency service.

• On-site diagnostic to identify the issue.
• Upfront parts and labor quote before work.
