"I had a great experience working with M&L Electrical Solutions. They were professional, communicated well, and completed the electrical work in a timely manner. They installed the exit signs and handled the wiring efficiently, and everything looks clean and well done. They also provided a referral for drywall repair, which I appreciated. Overall, very reliable and easy to work with. I would definitely use them again."

"Elliott does great work for a great price. He installed a new 100 amp breaker box and updated some of the house wiring to accommodate the new service. He also wired the newly renovated basement with all the wiring and installed all the outlets, switches and drop ceiling LED lights that have dimmer capability. He is meticulous in what he does."

"He showed up in a timely manner. He did the job quickly. There was a shorted wire that he had to re-run and pull through the existing pipe. So far it's all working great and has not needed to return. So far everything working great."

"This is the third time we've had him for various electrical jobs and all have been exceptional experiences.  He is prompt, efficient and thorough in his work.  I called him on Sunday and he was able to fit this small job in the next day so we could do laundry again.

"There is no air conditioning on the first floor of the non-profit house for which I am Property Director.  With the donation of and installation of a window AC unit, it was suggested that a ceiling fan in the living room (where the AC unit was installed) would help circulate the cool air.  I had worked w/Horizon Electric previously for electrical repairs, but not for an installation requiring new wiring, etc.  The owner, Lee, met me at the house within a few days and almost immediately found a way to wire in a new ceiling fan in the living room.  With further discussion we decided a ceiling fan w/lights would also be worthwhile in the dining area.  In that case he had to extend wiring to this adjacent room and, again, came up with a solution.   He quoted me a price for the installation of the living room fan only and another for the installation of both fans.  
With Board of Directors approval I was able to get back to him within the week and the following week both fans were installed. Even though Lee had told me that his workload was out 2-3 weeks, he understood the importance of getting these fans installed 
and that was done in record time.  The House Manager reported to me that the workman finished the installation of the fans we provided in one day, as promised, and, even with the house residents present (including young children), left nothing lying about that could be hazardous to anyone, was efficient and cleaned up the work area thoroughly after he was done.
We were billed the amount quoted.
I would definitely use this company again and highly recommend it.

Generator Install FAQs, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

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 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 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.
