"Working with Joel from start to finish was great! Very up front about the process, costs, and ensured he delivered on what I wanted and needed. Joel was extremely punctual with great communication which made my generator installation go very smooth. Pricing was extremely fair and I plan on using Smith electrical in the future for other projects. I would highly recommend Joel and his team!"

"George came to price an outlet installation for my new washer. He was so direct and honest and reasonable that I hired him to do it on the spot. Two weeks later the light in my bathroom ceiling fan went out. I called him to come out and instead he diagnosed the problem (correctly) through text and led me through some simple steps to fix it. If I could cook like my mother I would have baked him a pie. Instead I'm writing this review so that everyone knows what a great electrician and person George is."

"During the walkthrough John was easy to chat with on what we were looking for in this project. We were looking to get some ethernet drops installed so that a new hardwired ethernet and wireless network could be installed by North Shore IT ([*** Link removed ***] Once we agreed to the project, Bill and Nico were easy to work with and were very expedient. They completed the job over a day and a half and did a great job at minimizing the impact to the walls and floors. I would definitely recommend JP McCurdy electrical services to others and would use them again!"

"The Upwire crew did an excellent job installing a couple of different light fixtures in my kitchen. This was my third experience with Jim's team over the years and each time I am very impressed - the work is top notch, performed at the time promised and fairly priced, the site is left impeccably finished and clean. I would not use anyone else."

"We hired DiMasi to install TV antennas in our attic and run RG6 cables from the antennas to TVs on the first and second floors of our house. Peter DiMasi made a visit to our house and came up with the best route for both cable runs. His workers came a few days later and did the work. They were pleasant and worked steadily and quietly. Their work was very neat. No repairs needed in the house. They were good about cleaning up after the job. Reception is now excellent on both TVs."

"Steve comes highly recommended! He got back to me very quickly after I initiated a search for an electrician, and he arrived just two hours later! Steve is both friendly and professional and did a great job of installing a Nest thermostat and also showing me how my fuse box worked to get lights back on in my BR (which had gone off). He gave me an estimate before he came, and there were no additional charges or surprises. When I had a question later about the thermostat operation, he was helpful and took my call even though it was "after hours." Steve will be my go-to guy if I have another electrical issue!"

"Anthony called right away and showed up on time. Both Anthony and Patrick were professional, knowledgeable and efficient. They walked in the door and immediately put on their booties. They installed a ceiling fan in my bedroom and a light over my painting. They vacuumed and cleaned up after they finished the job. They are a new company and young but I would hire them again because they know what they are doing."

Generator Install questions, answered by experts

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.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window.
