"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.
"I hired Laurelton Electric (all communications were with contact person Michael B. Scheffler) in 2013 to install emergency standby generator. The site was inspected, all permits received, and all work was done over the course of several months (4-5?), 20 kW generator (model #0062440) with transfer switch was installed for about $12,000. After installation and all required inspections the generator was placed in service and I was offered annual maintenance contract for about $460, which included maintenance (oil, filters, test runs) on predetermined schedule. I never had a problem with the equipment and/or service for the last 5+ years. I believe I had annual contract renewed, as the other family member usually pays bills. The generator runs automatic tests weekly, it also worked as designed during infrequent power outages. On April 30, 2019 I noticed that the generator indicator lights showed that it is not working. It also did not run its usual self-test. Upon closer inspection I found the "low oil pressure" alarm and absence of the oil filler cap, also the generator cover lid was unlocked (I have the key, but I never had the need to open or to close it), allowing free access to innards to anyone. On May 2nd, 2019 I contacted Laurelton Electric (Mr. Scheffler) and explained the problem in detail. As it happened, it was realized that I no longer have a maintenance contract with the company. However, Mr. Scheffler expressed understanding and scheduled maintenance visit for me on May 6, 2019, from 9 to 12. After making necessary arrangements with my schedule I was waiting for the technician, who arrived at 12:15 pm. In fact there were two people, the importance of which I'll explain later. Once again, I described the problem and the technicians replaced oil filter, air filter, which they brought with them, and I was told that the generator has low oil pressure (duh!) and needs oil. They also found an oil filler cap, which was deep in the entrails of the generator... The workmen asked me if I would point them in the direction of the nearest auto parts supply store, as they had no oil with them. Did I not tell Mr. Scheffler that there was "low oil pressure" alarm when I called to schedule the service??? After leaving and returning in about 15 minutes, they poured two quarts of oil and attempted to restart the engine. It was still showing "low oil pressure" alarm... Another trip to the nearest gas station (about 5-7 minutes) for the younger one, and another two quarts go inside... At that time, being nosy, as I am, I helped them to figure out how to start the generator manually. (One had to turn it off and then press Manual start key). The senior technician (older one) mentioned in passing that he does not know what to do, he just knows how to change filters. Clouds of thick smoke and engine misfires ensued, raising the suspicion of oil overfill... I called Mr. Scheffler at this moment and expressed my doubts as to the mechanics qualifications. I was assured that they are fine. Now the masters proceeded to drain oil by asking me for some drain dish, which I provided, and by unscrewing oil filter and draining oil from oil filter attachment point. I am not a mechanic, far from it, but suspecting something is somewhat wrong, I went online, found the manual for the specific generator model, and printed relevant information for the technicians. There must have been some reading comprehension issues, as they were having difficulty finding the oil drain hose in its bracket, as described in the manual, which I had to point out to them. At that time I kind of took full participation in the process of getting my generator back in service. I was following recommendation in the manual and checking oil level with the stick, after turning the generator off, as opposed to the senior technician, who attempted to do the same while engine was running, creating a spewing oil fountain. After draining about quart and a half and running two more manual tests with subsequent oil level checks, the "job" was done. It was now 2:30 pm, total "work" time 2 hours 15 minutes, including the time for oil shopping trips. The technicians asked me to dispose of garbage, however agreeing to take drained oil with them. At 2:45 I was presented with the bill for services provided, for the total of $1,228.22. I called Mr. Scheffler who stated that the price is not negotiable. I offered for him to take me to court, as I refuse to pay. Mr. Scheffler used quite a few choice words to express his feelings toward me, then hang up, without bothering to wait for a reply. After some consideration, I decided that I will pay the cost of air and oil filters and oil (2 quarts), plus tax, the amount will be as described in Generac website for the full maintenance kit for my specific model, which is $65.88 (it also includes 2 spark plugs, that the technicians took with them, I was told that I don't need those). The rest of the charges are not payable, I chose not to renew maintenance contract with Laurelton Electric. It was good while it lasted, and who knows, maybe if there was some other technician, the outcome would be different. P.S. Please see the attached invoice to understand the relevance of my repeated mentioning of times and relevance of two technicians, one of which is younger."

"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
