"From the office folks to the electrician who did the work -- friendly and professional. They quoted the lowest price of three estimates and did the work within a couple of weeks. I purchased my generator elsewhere online... and VMA walked me thru the process of hooking it up, running it, and shutting it down. Very helpful."

"Jason and his team with Cotti-Johnson did an excellent job updating our electrical boxes, installing the washer/dryer hookup, and getting us setup with a generator! Sam, our assigned electrician, even took the time to go through the entire operation of the generator from A-Z. I would definitely recommend them for any electrical work!"

"Highly recommend Kevin and his son. Excellent work and great professionalism. Needed to have a new water heater wired in and Kevin was at my home the next day earlier than scheduled which was perfect as he was able to work along side our plumber. Kevin is now my electrician for all future projects. Thank you so much."

Generator Install questions, answered by experts

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

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.

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.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.
