"Tl;Dr; AVOID FOR ANYTHING BEYOND SIMPLE MAINTENANCE OR HVAC ONLY JOBS Our entire experience with the HVAC team has been great. They have been attentive, had no problem with cleaning out the vents, and installed a vent fan for us with no issue. I had no problem pay for what they charged. It was a good chunk of money, but I thought it was worth it for what they had to do. That brings us to the electric and administration in general. We were having a bathroom vent fan replaced and exhausting out from the roof. This required an electrician to come and install the fan. Additionally he was going to be looking at some electrical anomalies we were seeing in the house (GFCI flipping, inconsistent current). He wasn't told about the fan at all. He wasn't even really told about the GFCIs flipping either. So when he gets here, he gets sprung on him these additional things. He does the GFCI thing, isn't able to see the inconsistent current while he is here so doesn't do anything with that, and then goes to do the bathroom. He says he ran new conduit. Inspecting what is there myself, I can tell you there is no new conduit. Why would new conduit be ran when no new switches, no new functionality was added? He charges us well over $500 for installing that fan AND HE LEAVES A HOLE AROUND THE FAN DIRECTLY TO THE ATTIC. How does a company charge that without completing the job with no intention on following up? We contest the price we were charged for service with management and they keep dragging their feet to "try to learn more", offering to refund a charge that I wasn't trying to contest. They keep promising to call back but aren't. There is no communication between different members of the team except through notes that don't tell them anywhere close to the full story. When I finally heard back from them today, they came back with a "Well your wife was okay with paying it and the work" when she was under the (admittedly presumptuous) impression that the HVAC guys would fix the fan because, again, why would they leave a hole in the ceiling like that. Not only that since she she paid the cost there will be no discussion of refund for work they didn't do. The communication is extremely poor from them. Do not use them from anything that is at all more complicated that requires multiple departments or this is the risk you run."

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

Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.

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

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.
