"Artie and Greg came to our house multiple times for wiring related to a kitchen renovation. They wired our new kitchen island for an outlet and microwave. They also installed new high-hats and pendants in the kitchen. They were professional, competent, and efficient. They did great work and I would highly recommend them."

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."

Customers say: Quality work

"Artique Constructions did an amazing job with my bathroom and kitchen remodeling. Can not recommend enough for their quality of work and commitment to deliver to perfection. I chose very modern high end designs and their work was impeccable. I would have spent more than double if I had gone for anyone else. I got complete remodeling of kitchen(floor/cabinets/island/pantry/installation of all kitchen appliances/backsplash/open shelves/led ceiling lights) bathroom(bathtub/vanity/floor/bath tiles/built-in shelves/toilet), changed all switches and electric boxes, trims throughout the house, paint, door knobs, hinges, custom wall paneling. Garry made the house look like a million bucks houses featured in magazine. He is very trustworthy and patient. His attention to detail is amazing. Would suggest anyone who wants to get their house in amazing shape with no hidden costs Garry is the person to go to."

Generator Install FAQs, answered by experts

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

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.

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.

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.
