"I hired Rob Heiser to install 7 new light fixtures and a post light on my home's exterior. He also installed a path lighting system and a brush box on the outside of my house to connect outdoor speaker cables to my Sonance system. Rob and his sons did an excellent job and were extremely professional. He performed the job exactly as I asked and did a great job cleaning and organizing all the removed fixtures and trash before they left. I would highly recommend Heiser Electric."

"I reached out to many companies for information on a whole house generator and Sparkie Electric was the first to contact me. They answered my many questions even before they came out to give me an estimate. After recommending which generator would be the best fit for my house, we set a date for the install. Sparkie Electric arrived on time and worked non-stop. I appreciated their efficient, knowledgeable work ethics. All of the men were courteous, friendly and answered all questions or concerns. I have already recommended Sparkie Electric to several of my friends. Not anxious for another power outage but feel confident that should one happen, my generator will 'save the day"!! Give Sparkie Electric a call today!!"

Generator Install questions, answered by experts

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

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. 

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.
