"Called them out to get a free estimate. Gave 3 diff options for projects. Had to do a little back in forth as I had to amend one of the estimates but once that was done, got on their schedule in less than a week. Techs showed up when they said. Job completed quickly and they cleaned up after themselves."

"I am happy to share this review about Steven. He assisted Anthony with the installation of a new electrical panel, smoke and carbon monoxide detectors, and ceiling light fixtures. Steven was very conscientious and skillful. He was a pleasure to work with and was very respectful of my home by keeping the job site very clean. I feel confident that the work performed by Steven was to the highest level of quality standards."

"Jake did an amazing job. He is fast, efficient and affordable. He worked with me on a plan to add some receptacles and lights to my old house, and did a great job executing on the plan. He’s easy going and friendly. He fixed things and advised on other problems. He has a vast wealth of experience and found a workable solution for every old-house problem I had. Loving all the life he’s brought to previously unused parts of my house!! Thanks Jake!"

Generator Install questions, answered by experts

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.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

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. 

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.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.
