"# 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.

Electrical wiring or panel upgrades FAQs

A whole-house surge protector blocks voltage spikes from lightning, grid issues, or even large appliances before they can fry your wiring or electronics. By diverting excess current at the main panel, it shields everything from your HVAC to your phone chargers and can extend the life of pricey appliances. Homeowners in storm-prone regions or with older panels see the biggest payoff, but any home that relies on sensitive electronics benefits.

Most whole-house surge protectors work for two to three years. Low-level spikes—too small to notice—hit your panel every day and slowly wear down the internal components. Once the unit’s capacity is depleted, it can’t prevent a larger surge, so plan to replace it on schedule (or sooner if a major lightning strike occurs) to keep your electronics and HVAC equipment safe.

A surge protector begins guarding your circuits the moment an electrician snaps it into place. Whether the spike originates from a nearby lightning strike or your fridge kicking on, the protector shunts the extra current to ground before it can reach outlets or hard-wired systems, such as your AC. That instant response is why a small upfront cost can save thousands in appliance repairs.

The unit mounts on or next to your main electrical panel. Type 1 models sit on the supply side, catching outside spikes before they hit the breaker. Type 2 devices snap inside the panel and tame surges that start within the house. Either way, placement at the panel lets the protector guard every circuit at once.

Plan to swap the device every three to five years—or sooner if you upgrade your panel, add high-demand appliances, or notice flickering lights and tripped breakers. Relying on a maze of power strips is another red flag that your current setup isn’t keeping up. Replacing the surge protector at these milestones keeps your electrical system on safe footing.
