"We used this contractor in spring 2024 for wiring a line for an electric range. He responded quickly to my request for a bid, showed up on time, completed the job as planned and charged as agreed. James recommended some other upgrades to our electric system and provided an estimate. We decided to move forward in mid Sept, 2024. James came over promptly, reinspected the job and we paid 50% deposit $2250. We then waited and made multiple attempts to reach James by phone, text, email, voicemail, but got no response or acknowledgement, which was frustrating. We finally connected, got the power company scheduled for turning off the electricity. James showed up on time and finished the work as he proposed. James was very busy; we had to wait on the power company and inspectors. I wish he had just acknowledged my calls. We were very satisfied with James's work, his bids and promptness, just frustrated when I couldn't make contact."

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.
