"I had an electrical issue in my kitchen and the power to main floor went out. I ended up having a back switch that needed to be replaced. I was quickly contacted to understand the issue, and DLP Electric was willing to come out today, however I had already just hired a technician from another company to handle (right before I spoke to DLP). Having said that, DLP Electric was professional and very helpful, and I would hire them if I ever needed electric work performed in my house. Great customer service and very responsive."

"I contacted MDL Electric LLC Cooling and Heating on 01/19/19 Saturday evening via Angie's List messaging on my tablet. A response came within 15 minutes but I missed it since I didn't expect a reply that night. The first reply stated that someone would help me out first thing Monday morning. I replied the next day (Sunday 01/20) at 1pm asking for a specific time. The next reply on Angie's List messaging came at 7 min. after midnight on 01/21 stating 10-11 am but I didn't see it thinking "first thing" Monday morning implied around 7:30 when MDL states that they open for business. Another reply came at 07.34 in the morning stating that they would be arriving between 8-8:30 am. I also received a phone call at 7.35 am from Miguel the owner stating that Rudy was the name of guy that was coming between 8-8:30 am. At 8.00 am, the doorbell rang, the contractor came on time! Rudy arrived and I told him the problem and the possible culprits. I also mentioned that I was an Angie's List member and that MDL Electric LLC Cooling & Heating stated on their profile & website for 10% off if you were an Angie's List member and asked for an estimate of the price when he was done diagnosing. He simply replied that he didn't know and that someone else would take care of the pricing and billing. I was a bit hesitant but Monday was extremely cold: 6 degrees outside so I described my problem to Rudy hoping I wouldn't be price gouged. Another contractor stated they wanted $200 just to show up (diagnosis fee + more if additional work needed to be done) and MDL just sent someone to help correct the problem. I'm not sure if one is better than the other but I like doing business with family owned companies so I gave Rudy a chance. A non-GFCI outlet outside, 1 GFCI outlet inside near the sink, and other 2 other outlets that turned off appliances when I used them w/ an industrial strength extension cord from Home Depot. It could possibly be causing problems upstairs with the 2 switches in the bathroom if they were on the same circuit and that the house has solar installed. The last part is important because it scares away most contractors if they find out you have solar installed or the price quote goes up. It can be dangerous and it's always good disclosing the work environment before the contractor arrives. Two other electrical contractors saw that I had solar and just stated that they couldn't help me at all. I had already purchased a dozen commercial grade Levitron outlets but I didn't have any internal electrical wire or light switches for the bathroom upstairs and asked Rudy if he needed anything else. He inspected the parts that I provided then told me he'd be right back and went outside to his car to get his tools. Rudy went to the electrical panel, did a quick diagnosis and replaced the GFCI outlet inside the house. I showed him the outside outlet and he said that it should be a GFCI outlet outside. I agreed and he proceeded to install the GFCI outlet & non-metallic box that I had previously ordered for another job (that I was going to do myself but having solar installed scared me off). Everything worked after that, no need to replace any other outlet! The outside GFCI outlet was difficult to install but Rudy managed to fix the issue of the space behind the outlet being too deep. Before leaving, Rudy asked if I wanted him to fix the switches in the bathroom upstairs that I showed him earlier. I said no, leave them for another time since I did not have any parts for him to change out. I had a similar issue with a tenant at another location that needed to be diagnosed where there was no power from an outlet and the lights in a nearby room were dimming as a result. I asked if I needed to request another quote using Angie's List for the location or if Rudy was allowed to work at the other location once he finished up. Miguel called me on the phone and asked some questions then said that Rudy can follow me to the other location. I called ahead to make sure the tenant was home for the visit: no sense in wasting electrician & my time if tenant wasn't available. At the other location, Rudy went to the electrical panel, did some diagnosis and proceeded to replace an outlet that a non-electrician handyman had previously closed off. A little before 9:30, 2 locations, 3 replaced outlets (2 of them GFCI and 1 of them outdoors in the frigid cold) with diagnosis at both locations, job was completed. Tenant was happy, I was happy. Miguel called me at 9.30 am when the job was done and quoted me $350 for the job, with a 3.5% ($12.25) fee if I needed to use a credit card. I gave him my details over the phone and received a receipt for the transaction today via email which I provided to Miguel via text message yesterday. While I don't know if that price includes the 10% discount for being an Angie's List member, I figured Miguel can keep it as a tip for a job well done. I tried to use that other "free" contractor service but they kept trying to verify me before they would let me see a contractor list so thank you Angie's List! I apologize for the formatting, it was formatted before being submitted to Angie's List, afterwards, it looks like a huge block of text with absolutely no formatting. That's Angie's List, not my writing."

"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

Burton Electric was started to better serve this community. I have over 20 years of experience working right here in Passaic County and parts of Bergen County. My goal is to provide the best possible service at the best price. All of my pricing is up front and there will never be any surprises or wasted time on your job. I offer a one year warranty on parts and labor (excluding lamps)

"Not often I had come by a professional that is honest, reliable, responsive with fair pricing. Burton Electric has been the fourth electrician I have had making major repairs and installations in the two houses we owned in New Jersey and by far has been the best. Dave was punctual, worked very clean and was flexible adjusting and making changes as the work proceeded. He was attentive to my concern not to exceed my budget. Rarely a contractor will be encouraging saying "we can have 4 lights in this room and if it is not enough I will add more, but I think it will be enough." Saved me a couple of hundred dollars and was not tight with every little item he installed like a new and nicer plate here and there, and even replaced an old outlet and did not charge me. His estimate was the best of the other 5 contractors. Kudos Burton Electric. Highly recommended."

Generator Install questions, answered by experts

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

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. 

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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. 

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.
