"Let Our Family Work for Yours” At Laurelton Electric we specialize in electrical repairs and generator services for residential, industrial and retail customers 24 hours per day 7 days per week. Our dispatch offices service Manhatten, Brooklyn, The Bronx, Queens, Nassau ,Westchester and beyond” since 1935. We are 3rd Generation family owned and operated, Licensed, Bonded, and Insured, and offer FREE estimates. Our work is 100% guaranteed and maintenance contracts are also available.
"Hello - I hired LAURELTON ELECTRIC company (contact Michael Scheffler) based on original work of 1)installing a new meter( with appropriate approval from local Gas/Electric utility company - Con Edison), 2) move existing circuit breaker panel to a new location, and 3) separate circuit breakers from two meters into 3 meters and ensure all electric outlets are working per 3 new meters. The company sent two technicians on two separate days (Chris and Ashgar Ali) to confirm the work prior to start. The original agreement was for $500 deposit that will be held on a Credit Card, and when I pay for the full amount after job completion, then the company would not charge the credit card. As part of first phase of the work, when the contractor moved the existing electric panel to new location, not all circuit breakers are working as expected. He also requested $2,500 payment which was not part of the original agreement. In show of good faith I paid $2,500 with understanding that the contractor will correct the issue plus install the new meter. The contractor has not installed new meter (he needs to work with Con Edison to get permit and complete the work). Now he is requesting additional $3,100 for moving 6 circuit breakers from original panel that was moved to an existing panel .. which was part of the original work request. I am really frustrated with the bait-and-switch tactic and constant follow-up I have to do for this work to be completed. I am hoping Angie's list can intervene and get this work completed per original agreement."

Hey I am David the owner of Dave’s Electric LLC. Certify electrical technician specialize in all electrical work residential etc! I pride myself on the quality work I provide, while delivering great customer service. Check out the services offered below and call -or- click to schedule an estimate today!
"My main purpose was to fix the circuit connected to the fridge and router. He said the panel must be replaced to fix it. He replaced the panel and the circuit appeared to be working. However, the steam shower stopped working because he mistakenly connected it to a 110 power source instead of the original 220. I called him few days later and he sent his guy who fixed the steam shower connection. About a month later, the circuit in question stopped working properly and we had to connect the fridge and the router to another circuit through a long extension cord, which we still have until now. I called and left messages and he refused to respond."

"After getting several quotes, last year we hired GenReady to install a house generator. Ed, the owner of the company impressed us from the start. He was knowledgeable and patiently explained the process as well as answering our questions. We knew right away that GenReady was the company for us. Lindsay kept us up to date as we moved along in the process. Our generator was installed last July. Andrew and his team installed the generator with expertise and efficiency. They took care to leave our house and yard spotless. Lindsay and Andrew were always happy to answer my questions and address me concerns. We’ve needed the generator only once (thank goodness) when our power went out due to a necessary power line repair after a car crashed into a utility pole on our street. When the power went out, our generator turned on within seconds. Our house was up and running for the four hours the line repair took, and if it weren’t for the blink of lights, we never would have known our generator was running. Every other week, our generator self tests for a few minutes giving us peace mind that it will be here for us if and when we need it. Just like the generator, GenReady is a company that runs efficiently and seamlessly. Just today, Lindsay called to tell me someone would be coming tomorrow to change the oil which reminded me that I am long overdue in submitting this well deserved rave review. Thank you to the entire GenReady team (and to Great White Propane) for all you’ve done to help us know we can weather any power outage."

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 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.
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
