"Very professional and timely however very costly. I would use them again for large and complex projects however I would look to use another company or person for less complex projects (e.g. replacing wall sconces, replacing a dimmer switch, and installing a new dimmer switch). Would have liked for the cost for the service call/ quote to be rolled into the cost of any work that done rather than an additional expense."

"Tri-County Electric Services was able to send a plumber out the next day to provide estimates for a few projects in my home. Chris M. arrived at my home and was professional, knowledgable, straight forward, and friendly. He quoted me fair prices to install a new toilet and new kitchen faucet, both of which I had previously purchased independently and had at home ready to install. I was very happy that he was able to complete the installs that day. He also fixed a minor leak below a bathroom sink. All around a great experience! I will definitely hire them again for future plumbing needs. Chris explained that the company recently added a plumbing division to complement their electric services. Thank you for a job well done!"

"I estimate I have just under $100k in electronics and appliances in my house. We have significant lightning storms in my location. To NOT have lightning suppression installed is significant risk in my mind based on my location in New Jersey. RS LIGHTNING PROTECTION was responsive with a quick cost estimate and a reasonable price based on my research for installation. By the way...installation is part art, such as bends in cable are not more than 90 degrees. It's not just about running grounded cables. This installation in conjunction with surge protection on my electrical panel performed by my electrician and cable protection gives me significant piece of mind that all my appliances and electronics are protected from lightning and any potential surge generated by a near strike. Mr Richard Sherlock knows his subject. Highly recommended. Five stars."

Generator Install questions, answered by experts

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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.

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.

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.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.
