"The two young men who performed the installation were informative, professional, cordial, and they left the scene spotless. There was a technical problem with the engine on the generator itself, which they weren't able to help with, because they weren't licensed to work on the specific brand of generator. That might be something to check on before hiring for this type of job."

Customers say: Quality work

"I had a bathroom remodeled. The project started as a disaster. I had fired 2 contractors, lost money and time and really did not know where else to turn to. I was suggested to try Angie list, and so I did. I got in contact with Mr. Mc Caffrey, I did not have much faith however he surpassed and exceeded all my expectations. He was on time and showed up for work each single day he promised he would. The price was competitive and the bathroom was done in 10 days. The job included a jet tub,installation,plumbing, carpentry, electrical and tile work. I am greatly appreciative and will recommend Mr. Mc Caffrey at any time."

"Joe told me he would be at my house at a certain time and he was true to his word. He had to first remove a small wooden work bench —the wood pieces were put in a contractors garbage bag and removed to his truck— then he removed the old fuse box and put in the new circuit breaker. Joe finished the project and even swept the area and left it neat. It was a pleasure to have Joe do this job and I will happily recommend him for any electrical job you need. He is pleasant and curious."

"Preston was great to work with! He was quick to respond to my request for a quote and was at the house three days later to complete all of the work. He installed a hybrid car charger, fixed some outlets, installed a new thermostat and answered all my questions with patience and knowledge. Preston is incredibly friendly, worked so hard and I won’t hesitate to recommend him to family and friends and anyone else asking me if I know a good electrician!"

Generator Install questions, answered by experts

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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. 

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. 

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.
