"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"

"Steve and his team have done a number of jobs for me from installing light fixtures to adding additional outlets in the bathroom which required going underneath the house. They are professional, timely, courteous, clean, reliable and reasonably priced!"

Generator Install questions, answered by experts

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more.
