"We moved to Vero Beach from New England and purchased a new portable generator that ran sluggishly. I contacted Brian, who came to Vero to trouble shoot the generator and work with the supplier. After assessing and determining the gas and electrical hookups were effective, Brian realized the supplier's natural gas regulator was defective. The supplier sent us a new regulator which Brian came back to Vero to install. Brian also noted that the gas line provided was too small for the unit and contacted the supplier who provided us the proper hose. I can't say enough good things about Brian. The service he provided was excellent, and his commitment to helping us finally get our generator operating properly was noteworthy. Highly Recommended."

"Forrest is a professional all the way. I would trust and hire him for any job he can do, and maybe some he cannot. Honestly decent from the heart and concerned about his clients. He took time to guide me through a hands-on start-up of the generator he installed. Forrest made sure to clean the area he worked in and was extremely polite."

"I hired Ben to install a generator plug and a few misc electrical duties. He was very professional, timely, and the work is unmatched. During one of the electrical outlet installs he brought parts of my home up to code which I greatly appreciate. He talked me through the different options on what he recommended and I trusted his judgment-luckily everything worked out perfectly. I highly recommend this young man and itâ s always nice hiring small American business."

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.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

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. 

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.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator.
