"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."

From the first point of contact through point of completion Kevin's level of professionalism, customer service and follow through were beyond exceptional. He is very skilled and knowledgeable in the electrical field. He was able to answer all of our questions and we knew we made the right choice.

"Dave, was professional and reliable. He did the job very well and returned when we had questions and resolved them. We upgraded our service from 100 to 200 amp electrical service. We also installed a charging port for our new electric car. We are very satisfied with the new service and charge station. I would highly recommend him to others."

Generator Install questions, answered by experts

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

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.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.
