I pride myself on my professionalism, as well as my ability to complete each project to the customer's total satisfaction. As a Master Electrician, I practice the National Electric Code, job safety and never leave a project unfinished, or a customer not 100% satisfied with my level of service.

"I have asked for an itemized receipt for the 70 minutes the electrician was here. I have texted 4 times this past week with no forth coming receipt. It cost me $675 for screwing in 5 outlets that were extended from my new backsplash (I had to rescrew 2 because they were crooked) and remove a ceiling light and replace it with a ceiling fan/light unit. No new electrical box was needed and he stated it was easy to install. No additional wiring or parts were needed. I had to clean up around the new fan because no drop cloth was used in the instillation and take the trash/boxes to the dump myself. Very, very expensive and not meticulous in his work."

Generator Install questions, answered by experts

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.

When properly maintained, natural gas generators can last a long time, as much as 20 to 40 years. They have relatively few needs compared to generators with other fuel types. However, the generator’s lifespan ultimately depends on how often the generator is used and for how long it’s left running.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
