"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."

"Electrician provided excellent service, told me what he was going to do, listen to Meyer concern regarding the location of the outlet, and cleaned up upon completion of the work. Afterwards he demonstrated how the placement of the outlet allowed me to reach my EV without any issue."

"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

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

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. 

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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.
