"# 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.

FAQs for electrical wiring or panel upgrade projects in King Of Prussia, PA
While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.
A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.
Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.
The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.
A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.
While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
