"Project: Install Electrical Switches, Outlets. They were on time, professional and flexible. Also, discussed future projects - replacing a fixture in bathroom, and on their way out attached a smog detector the right way. I would definitely use this company again."

"I had 2 ceiling fan/lights installed in the bedrooms. Installation included 2 new circular circuit boxes in each bedroom ceiling. In addition, I replaced the kitchen ceiling light with an LED fixture. The 2 workers were very polite and professional and worked quickly and efficiently, in addition to being respectful of my personal belongings."

"Matt was the only contractor that actually dove in to the project for the bid. He realized that we needed an upgraded panel to support our installation. Every other contractor assumed the panel had openings under the blanks, but there were used by solar and backups. Quoted installation time was right on. Very professional and quick to respond."

"EFI installed a electrical hookup for my RV. Very professional with superior service and workmanship. Now I have a convenient and accessible outlet for the RV. No more plugging into my household outlets that would trip within hours... If you want piece of mind with high quality of work from an electrician with years of experience that can handle big and small jobs, then EFI is the one to call. They also provide a competitive bid that saved us money."

"I recently hired Chris to install an EV charger for our home. The job seemed simple at first but ended up being a bit more complicated. But Chris was patient and really thoughtful in figuring out the project and explaining it to me. He didn't change his bid even with the complications and got the job done on the day he committed to. Chris is REALLY good at explaining electrical stuff to a very non- knowledgeable customer (me!). I learned a ton working with Chris and know how to talk about AMPS now! I have no doubt I will go to Chris for all future electrical needs."

"Rick replaced my HVAC system. The process was seamless. We scheduled an appointment to inspect the existing system, and the available options were openly discussed. All of my questions were answered in a timely manner. There was no pressure to choose one system over another. In comparing his estimate to other companies, I found that I'd saved a lot of money. We discovered an incompatibility between the new equipment and the yet to be installed alarm system. Rick worked closely with the alarm company to make to marry the two systems. We gave the go ahead and the new system was installed in a day. The installation crew was polite and professional and so very careful to clean up afterwards. Thank you, Bragg Home Services. Yes, I recommend this company"

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 wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.
