"From the office folks to the electrician who did the work -- friendly and professional. They quoted the lowest price of three estimates and did the work within a couple of weeks. I purchased my generator elsewhere online... and VMA walked me thru the process of hooking it up, running it, and shutting it down. Very helpful."

"My wife and I hired many subcontractors to complete a large addition to our house. Belcastro Electric was easily the best experience we had with our subcontractors. The companies owner Andy came out to our project and provided a timely and accurate bid of what the job would cost. He provided many helpful suggestions on lighting choice and switch placement to make the best practical flow when switching on and off room lights on a daily basis. He balanced the newly upgrade circuit panel and subpanel perfectly so we get no flicker even when our 50 amp mini-split system kicks on for us. This was a large issue our neighbor had when installing the same mini-split system as us but used a different electrical that simply added on but did no take the extra time to balance their panel properly so they get light dimming and flicker when their minis come on which is annoying for them. Our ceiling fans and pot lights look great. His crew is professional and arrive in clean well stocked vans. I was amazed at the inventory of stuff they were able to pull of these vans as they wired both high voltage and low voltage equipment they had multiple wall plates and connectors for us the pick from when setting up TV, stereo, phone, and internet. The thing that stands out most about Belcastro electric was Andy's ability to get extra crew here when needed. We had a time crunch for inspection and Andy was able to get 4 guys on my project to finish a day early. If you have a project you want done right, on time, and on budget then hire these guys. Trust me not all subcontractors we hired went this well. 5 stars would use again. -Matt"

"Very responsive, came out for a quote in a timely manner which I can't say many others did. Has responded quickly to my emails to answer any question I have posed. The crew came on time to position the generator and had it in place as described. As soon as Tim and Robert were notified of gas connection they scheduled final install, showed up exactly on time and completed work in a very professional manner. Very happy with the entire process."

"Steven did a phenomenal job installing a new 30amp interlock device at existing electrical panel and install 30amp 240 volt outdoor receptacle for standby generator. Affordable, reliable, and was great to work with. Steve was personable, professional, and I would highly recommend him for any electrical work need in your home or business."

"Generator would not start and if it did start, it would not run for long. Disassembled the carburetor, examined it and reassembled it. Engine starts and runs. All in his magic touch I guess. But I am very glad I now have a generator that runs since a storm is due to arrive within hours."

Generator Install questions, answered by experts

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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.
