"Mike and his assistant replaced my seriously outdated smoke detectors in the basement and first floor, replaced a second floor smoke detector with a combo smoke/carbon monoxide detector and in the attic replaced a heat detector. While at my house, they also looked at a poorly installed outlet in the basement and brought it up to standard and installed an outlet on my front porch! They were quick and extremely helpful and left no mess behind. I will definitely call MKS Electric again if I need any further electrical work done at my house."

"Troy did an amazing job on several projects for us. He installed a 220 sub panel box and wired in a new hot tub. Additionally, he wired up our basement during a remodel, same as a new construction build. We hired him back on for the project due to the professionalism and fairness he brought with him on his first job with us. I’m a meticulous guy and picky about how my electrical work looks. Troy came in above and beyond of what I was expecting with his order of neatness and cleanliness when laying his lines. Everything had to be perfect for him and I feel he exceeded what my high expectations were already. I would certainly only consider him for whatever our next electrical project is."

"I recently had an EV charger installed, and I couldnâ t be more pleased with the experience. Mike, the owner, was prompt in providing a competitive estimate and gave a clear, detailed explanation of the work to be done from start to finish. On the day of installation, the team completed the job ahead of schedule, working efficiently and with great attention to detail. The installation was done neatly, and the crew was both cordial and friendly throughout the process. I would highly recommend this company for any future work."

"We were walked through the products and installation as well as the benefits of a heat pump. The install was done in one day. Very quick and efficient. We've had the units running for about a month and they are awesome. We're very happy with our decision."

Generator Install FAQs, answered by experts

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.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.
