"Sparky?s Electric did an excellent job installing my EV charger. They were professional, knowledgeable, and showed up when they said they would. The installation was clean, everything was explained clearly, and they made sure everything was working properly before leaving. Pricing was fair and the quality of work was top notch. I would definitely recommend Sparky?s Electric to anyone looking for electrical work or EV charger installation."

"I have used the electric company for several jobs, and they have always been professional, efficient, and great to work with. From installing an exhaust fan to a whole new panel no job is too small or too big for them."

"I had many things I needed upgraded around my house. I feel they were a bit ambitious with the time frame thinking everything could get done in one day. They had to come back the next day to finish up. They did a fantastic job with everything and didnâ t have any problem when my wife wanted a few more fixtures installed. Really good guys that do professional work. Price was lower than other bids I had as well."

Generator Install questions, answered by experts

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.

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. 

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

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. 

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.
