"I could not have made a better choice of a company to purchase and install my standby generator from . From the day I called for a quote for a standby generator to the time it took to complete the installation (about 3 weeks) everything was done in a courteous and professional manner. The work was faultless and the cost was less then I had anticipated."

"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 I hired ABN to replace outdated two-prong outlets with three-prong GFCIs, and install a completely new outlet in my bathroom, and they did an incredible job in no time.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

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.
