"I have been hiring Cody Malone since we purchased our house in July 2012. They have switched out outlets, installed indoor ceiling fans, installed outdoor ceiling fans, ran electrical to my outdoor water feature and switched out my light fixtures. I plan to hire them again when I add electric to my detached garage. They always do a great job and arrive when they say they will. I have never had a single issue and they have been to my house for no less than six different projects!"

"The guys arrived exactly at the prearranged time. They informed me that the work would take longer than the '2 man hours' that I bought through the Angie's List Deals before they began the job - which I appreciated.  They were on task and professional the whole time. They explained any problems they encountered while re-installing the old light fixture - need new bulbs.  They cleaned up any mess they made at the end of the job. Rates and cost of supplies were reasonable.  I WILL BE CALLING THEM BACK FOR ANY OTHER ELECTRICAL WORK IN THE FUTURE.

"Atlas was the first electrician company to respond to my request for quotes. All they needed were pictures of my fixtures to be installed and my explanation of pre-installed switches and wiring, in order to give me a quote. Other companies that responded wanted to charge me $75-$100 just to come out and give me a quote. Atlas was able install my 3 fixtures very quickly and did an outstanding job. I will definitely use them again when I have the need."

"You cannot find a better contractor than Raufi Services. We hired Raufi Services to install 240V/50A wiring for a hot tub. They were extremely efficient, polite, and timely. The quality of their work was outstanding--I couldn't even tell they ran the wiring in the house after they were done. They were also very competitive in their cost estimate."

Generator Install questions, answered by experts

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.
