"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 questions, answered by experts

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

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.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.
