"Perfect and smooth journey, Jorge came pre instillation to check the electrical panel and where the the charger was going to be installed and after the review he text me the cost of parts and installation, after I received the charger he came on time and the job was completed. I was updated by text messages throughout the process. In the future if I need any electrical work I definitely use JK Flores Enterprise."

"It went very well. Very professional. Cleaned up so well afterward, no one would know we had anything installed. He walked me through each installation to be sure I was happy with the install and knew how to work each fan. I also appreciated that he offered suggestions as to what made the most sense. A big help. On top of that, he noticed an air duct issue in the attic that we were unaware of. he took a picture of it, and shared it with me so I could get someone to fix it."

"We needed a NEMA 14-50 EV charger installed outdoors for an electric car, and got 3 quotes from Angie's List. Based on the 3 bids, it seemed certain we'd need a subpanel breaker box installed as our main breaker box was full and there were no empty slots to assign to the EV charger. However, only Tommy from Fairway offered up a potential solution within the existing breaker box, if they were able to source a hard to find quad breaker. It seemed unlikely, but would save a lot of hours (new box install / wiring under the house) and money. Sure enough, he source the part and made it happen. On top of that, they were professional and easy to work with. Highly recommend!"

Generator Install questions, answered by experts

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.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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. 

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

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.
