"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 can highly recommend Benjamin for electrical service. He is very prompt, friendly, answers any questions, and does a quality job. I'll be sure to use him for some other projects I have coming up."

Generator Install FAQs, answered by experts

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.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

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.
