"Mike and his assistant replaced my seriously outdated smoke detectors in the basement and first floor, replaced a second floor smoke detector with a combo smoke/carbon monoxide detector and in the attic replaced a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."

"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."

"I would recommend this electrician to everyone I know. We purchased a new home and they were very flexible working around the plumbers and the carpet installation as well. The work is top quality and they were very accommodating to our vision for what we wanted. Corey also made helpful suggestions as we planned the project for things we may not have thought of and let us choose what we wanted. Couldn't be happier with the entire experience!"

"Excellent and efficient service, on time for appointment, repaired our Generac generator with OEM parts. I've always believed, if you can't explain it simply...you don't understand it well enough. This guy knows his stuff. The technician explained all repairs while making recommendations for future care and preventative maintenance. We understood and felt confident in our maintenance/repair decisions. One stop shop for generator, electrical and heating repair and including oil and propane products. We will be using them going forward for their services. Highly recommended!"

Generator Install questions, answered by experts

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

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.

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’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.
