Customers say: Terrific value

"I would highly recommend Santella for residential electrical work. I requested quotes from multiple companies for a wide range of work, including bringing existing wiring to code, repairing issues, installing new outlets, junction boxes and external lighting and video. They were excellent with communication and follow-up, transparent in pricing and risks/assumptions, were available more quickly than others, and offered competitive pricing. On the job they were fast and efficient, professional, didn’t try to up sell, did high quality work, and cleaned up. I will be using them again for all future work."

"Installed new boiler, indirect hot water heater, and rebuilt our well water system adding conditioning and softening. We have acidic well water that has been a problem. Now, everything has been corrected and works great. The new boiler is smaller and quieter. Very professional and completely trustworthy."

"5++++Rj Mazzucca is amazing. Awesome salesman, awesome craftsmanship, went above and beyond. Was happy how quickly someone got out here to look at. Within hours of me calling and by the next day installed. I know I could have got a cheaper price, but was afraid it would not have been done in a timely manner. This is a 1979 mobile home and everything is old and turns into a project when replacing things. Rj did an excellent job."

Generator Install FAQs, answered by experts

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

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.

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.

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.

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.
