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."

"I hired Kyle to install the electric for my pool. He grounded the pool, installed an electrical timer for the pool pump, breakers for the circuits, and installed an outlet. I liked the quality of the work so much that I hired him to replace a GFCI outlet in my kitchen and an exterior outlet on my house and then hired him once more to install light fixtures. His prices are fair and his finished product is meticulous. If he tells you that you need something replaced/repaired he is not saying it to make money, he is saying it because the repair/replacement is necessary for safety or code purposes. I would hire Kyle again for any of my electrical repairs/installations."

FAQs for generator install projects in Holmes, NY

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:

  • Portable generators with 1kW–7.5kW capacity: $500–$2,000

  • Partial generators with 9kW–20kW capacity: $2,000–$6,300

  • Whole-house generators with 22kW–48kW: $5,000–$18,000

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:

  • Experience frequent or prolonged power outages

  • Work from home

  • Store a lot of cold food

  • Have a sump pump

  • Have a pump for well water

  • Use electronic medical devices

  • Live in a climate requiring heating or cooling
