"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."

"The owner responded quickly and came to our home for a free estimate within hours. He recommended installing a new outlet to prevent electrical issues down the road. The job was completed within 72hrs (due to the weekend) and we were very happy with the work. I would highly recommend and will use them again for future needs."

"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

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

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. 

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
