"We have a smoke alarm that is located 20 feet u from the floor. Several people declined to come out, including one that wanted $89 just to come and give us an estimate. The $89 did not apply toward the estimate if we accepted. Richard Riley, from Electrical Edge, had us text a picture and said he would be happy to do the job. He showed up on time and was very professional. We plan to use him on some other projects as well. Chris and Chuck Gibson Scotts, MI"

"Keith and Mike were wonderful. Great service and knowledgeable in their craft. The weather was terrible when they came to install my decorative outside shutters and they still got the job done in a timely manner. I will use them again and listen to their suggestions!"

Generator Install FAQs, answered by experts

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

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.
