Customers say: Quick response

"After scheduling, they contacted me to say there was a new opening for an earlier time, so we were able to get the project done even sooner, and they had better prices than the other people I had talked to. The technician was prompt, very nice, and did amazing work with the lighting fixtures. Everything came out leveled and centered. Would recommend to anyone!"

"My daughter & s-i-l recently convinced me to have Doug install a whole house generator. He had already talked to my s-i-l about it when he came out to see what I needed. It was going to be tricky as I already had solar panels & didn't want to lose the credits I got from DTE for the excess power they created. After much research & learning, Doug was able to figure out how to get the generator connected so it runs automatically but my solars still work, too. Today, they finished it up & I now have backup power as well as my solar panel system helping with the electric bill. This took a LOT of extra work but he and his crew handled it as quickly & professionally as anyone could have expected. Yes, it took longer than a typical generator install but it was not a typical situation. He also had to completely upgrade my service panel which was old, outdated & a complete mess. I've had some good contractors work on my home but he & his guys are the best!! He's fair & honest & patient!"

"We were very pleased with the quality and service we received. We hired Kevin to wire our new construction house project in 2018. We later had him back to install a 12KW solar panel system and an EV charging station in 2021. I highly recommend Kwaske Electric."

"We lost power after a horrific storm and we contacted them and they sent a tech out after hours and got your generator back up and running. I would highly recommend. Will use again if this ever happens again and we will be referring all of our customers, family and friends to. I'll take care of you guys!"

Generator Install FAQs, answered by experts

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

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. 

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.
