"Andrew came to our house between Ann Arbor and Plymouth at 8 PM on Tuesday when a storm caused an electrical outage. We had a generator but we're only getting partial power in the house. Andrew ran tests inside the house, determining that not enough power was coming into the house. He then started testing different areas of the generator until he found the part not working. Once he located the problem, he quickly fixed it. Because he didn't give up on me or my problem, he restored electricity, saving me hundreds from food spoilage in a refrigerator and freezer. I don't think most electricians would have stuck with the problem or been able or willing to fix the generator. If I could give more than 5 stars, I would."

"John went "above and beyond" in installing the new A/C system.  He fixed mistakes made by the previous contractor when the old A/C was installed years ago.  He even came up with a creative idea to disguise the pipes/lines running along the side of my house to the condenser, it looks so much better!  And, as promised, the condenser is quiet. 
John cares about doing a job correctly and pleasing the customer.  In fact, he tested my furnace and discovered a problem with the gas line and immediately called the gas company to come over and followed up with me afterwards.
I won't hesitate to call on him again the next time I need work done.

Generator Install questions, answered by experts

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

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. 

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.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency.
