We offer the best quality electrical work, we strive into quality work. Very responsible on our schedule. We offer a clean environment, leave the project cleaned and strive on making the project go smooth as possible and avoid hassles and drama for homeowners.

"In May 2024, we embarked on an ambitious project in southwest Michigan, but ran into a significant setback when our original local contractor failed to show up and abandoned the job for over two months. Fortunately, we were referred to D-Best Electric by another contractor, and it turned out to be one of the best decisions we could have made. From the moment Oscar and his talented team took over, we experienced a remarkable turnaround. They not only completed the project within the agreed timeline, but their expertise and attention to detail were truly impressive. The crews were exceptionally knowledgeable, demonstrating a high level of professionalism and skill in every aspect of their work. What truly stood out was how D-Best Electric went above and beyond by addressing numerous additional requests and adjustments without any hesitation. Their commitment to customer satisfaction and excellence made a significant difference in the overall experience. Given our outstanding experience, we will undoubtedly rely on D-Best Electric for all our future projects. I wholeheartedly recommend them for any residential or commercial electrical work—trust me, you won’t be disappointed!"

Generator Install questions, answered by experts

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

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.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
