"I hired this company for spring cleanup, and when they got here they were able to do so much more They edged all my beds. They mulched everything. They filled my new raised beds with loam. They cleaned my two ponds. They went way over and above what I expected, I would recommend them highly to anyone. They .were professional. They were courteous. They left nothing behind. It was absolutely the best experience I’ve had hiring someone in a long time. I couldn’t be happier. I would highly recommend them to anyone for any projects."

"Extremely satisfied with Andy and Kyle. They are both professional, knowledgeable and personable. They installed a new motor in the attic for our bathroom exhaust fans. A previous electrician had told us it would take maybe a few weeks to a month or more before he could secure a new motor. Andy got us one within a day! He also was able to diagnose and fix a crazy mess left from that previous electrician with wiring our old timer unit. We are so thankful we finally found a decent, caring electrician and would hire them again in an instant. We put our trust in them and were not disappointed. We highly recommend Belcastro Electric."

"An outlet wasn't working.  Called and he said he'd be there that day or the next.  Arrived as promised the following day.  Pleasant, efficient and got the outlet working.  Would definitely use him again."

"Punctual and professional. All of the work was completed right on schedule. They upgraded my entire home and replaced electrical panel. Definitely hiring again; I have them scheduled to repair the sprinkler system electrical work and the fans in both my bathrooms. The cost was surprisingly affordable! I cannot recommend enough."

Generator Install questions, answered by experts

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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.
