"Unstoppable Electric LLC just installed our Tesla Wall Connector, and wow—what an incredible experience. They were super responsive from the first message, easy to schedule, and showed up right on time. Max is very knowledgeable, professional, and genuinely nice to talk to. He took his time to do everything perfectly—clean, precise, top-quality work with no rush whatsoever. Explained everything clearly, made smart suggestions, and left the garage looking flawless. Pricing was fair and transparent—no surprises. Definitely now my go-to electrician in the area! 10/10 recommend! Thanks again for the stellar work! ⚡️🚗"

"I highly recommend Sparks Electric. They recently completed an electrical box expansion, installed two ceiling fans, and replaced two bathroom fans in my home. Blake provided an itemized quote for a fair price before starting the job. His team arrived on time, were polite, and cleaned up after themselves. They also had excellent communication throughout the project. Iâ m very pleased with their work and recommend them to anyone looking for electrical work."

Generator Install questions, answered by experts

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.
