"I can’t recommend Botelho and Sons Electric highly enough. From start to finish, the experience was outstanding. They were punctual, neat, and completely reliable, showing up exactly when they said they would and keeping the work area clean and organized throughout the entire project. I had a 200-amp panel upgrade, lines run to a pool & hot tub, copper wire installed for the pool and the connection for our generator - everything was done to code, with obvious skill and attention to detail. Out of 6 electricians I got quotes from, Ryan offered the best price without cutting any corners. On top of that, both he and his employee were incredibly knowledgeable and professional. Bonus points for being amazing with my 130 lb Cane Corso, who is usually suspicious of strangers. It was clear they were comfortable around dogs and respectful of my space, which made the whole process that much smoother. If you want high-quality work from someone you can trust, I wouldn’t look any further!"

"I highly recommend Ben @ ABN for your electrician needs. I hired ABN to replace outdated two-prong outlets with three-prong GFCIs, and install a completely new outlet in my bathroom, and they did an incredible job in no time. Their professionalism, skill, prices, and good attitude were excellent. I will be hiring ABN for all of my future projects too. Thanks!"

Generator Install questions, answered by experts

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit
