"# Generator Repair Nightmare Had issues with my Generac 32KW (installed March 2023). In January 2025, it wouldn't start. Feb 4: Submitted service request Feb 11: Mike came but couldn't fix it Feb 26: Replaced part - didn't work Mar 14: Replaced another part - still broken Apr 2: Replaced wiring harness - no success Major problems with this company: - Poor communication (weeks of silence) - Multiple failed repair attempts - Technician eventually said "I CANNOT FIX IT" and told me to call Generac myself - Never sent promised documentation of work done During a March storm, I spent $1000 at Harbor Freight on a temporary generator. As a business owner, I'm appalled that a certified Generac contractor would give up and shift responsibility to the customer. After two months of "service," my generator still doesn't work. You can see my full review on their google page. https://www.google.com/search?q=lightning+technologies"

"Highly recommend! John Gambino Electric rewired our 100+ year-old house, removing knob and tube, other outdated wiring and bringing every room and the garage up to code.

FAQs for electrical wiring or panel upgrade projects in King Of Prussia, PA

Electrical wiring can last between 50 and 70 years if properly installed and maintained. However, factors like moisture damage and overloading outlets can shorten this lifespan. To extend your wiring's life, unplug electronics when not in use, avoid overloading outlets, and schedule regular electrical inspections every five to ten years.

If your house was built in the 1960s and hasn't been rewired, it likely needs it. Older homes may have outdated wiring like knob-and-tube, which poses fire risks due to flammable insulation. Rewiring ensures safety and may also require updating your circuit panel, outlets, switches, and fixtures. Contact a local electrician to help with your rewiring needs.

Yes, rewiring your house is worth it, especially if your wiring is outdated. It improves safety by reducing fire risks and can increase your property's value. However, you may not need a full rewire. A home inspector can tell you if a partial rewire will bring your home up to code.

Yes, you can sometimes rewire a house without removing walls. Electricians might access wiring through attics, basements, or crawl spaces, or make small holes to run new wires. However, this isn't always possible, and in some cases, removing sections of walls is necessary to ensure the wiring is installed safely and meets code.

A house should typically be rewired every 25 years to maintain safety. Over time, wiring deteriorates, increasing fire risks. Regular electrical inspections every five to ten years help assess the need for rewiring. Staying proactive with maintenance ensures a safe, efficient electrical system and prevents potential hazards before they become serious issues.
