"Roy is really a prof. He installed two overhead fans and a hanging lamp. The fans had a complicated control system but he was able to get them to work flawlessly. Bonus: he is really a nice person and he cleaned up too! I would recommend his work to anyone."

"Frank and his team did a fantastic job upgrading our electrical panel and wiring for our generator. He even came out to help us during off hours when we needed help with starting the generator! He is quick to get back and does above and beyond. I highly recommend and will use his company again and again!"

"I asked for a team to install and wire 8 kitchen can lights. Great professional team that came in on time, did a great job protecting the kitchen, finished the job in less than 2 hours, and cleaned up behind themselves entirely. They charged a very reasonable price, and made the whole project as smooth and seamless as possible. Definitely recommend for your project."

"Darren, the owner of Mr. Sparky, was both very knowledgeable and accommodating.  Our appointment to install an external generator connection box and power switch at the main electrical panel was made around our schedule and convenience.  The day before our appointment (Sunday), I left a message for Darren to call me and asked if he could come to our house by 8 A.M. that Monday (had previously specified "morning" only).  He said he would "try" not knowing how badly his service truck was buried at the shop after a 28 inch blizzard just hit us on Saturday.  Nevertheless, Darren arrived bright and early at 8 A.M. sharp the following morning, albeit, a little tired.  He explained that he had gone to his shop late Sunday night to dig out his truck so he could make our requested appointment time!
His installation of the new switch was very professional and he was very considerate about making sure our rugs were kept clean even though the conditions outside after the snow storm were still very bad.  He took the time to show my wife and I how to operate the new switch and advised us on what appliances could be used in the event we needed to run our 6000 watt generator.
As it turned out, Darren was also able to find a potential fire hazard in the original panel wiring.  A neutral wire in the terminal block must have been loose for a long time and showed signs of overheating.  Darren came back later that evening and fixed it at no charge.
We highly recommend Darren and Mr. Sparky as a home electrical service company and we would definitely use them again!

"Extremely well. Although the generator was installed some time ago by Doug, a new problem arose with the central air conditioning when the electric power went out and the generator needed to run. Doug spoke with the company servicing the generator and the air conditioning to find a solution and fixed the problem. At my request, he communicated long distance with my son (an engineer), to explain what was happening, as I had little knowledge of the problem and solution. Doug spent considerable time and triple checked that the solution was working before he finished. As always, Doug was extremely caring and efficient."

Generator Install questions, answered by experts

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

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.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

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.
