"They werenâ t able to install lighting in my brick pillars after I purchased new lights per their request. They said the pillars would probably need to be taken apart to find the problem.They did some rewriting work and it was ok."

"CD Electric was fantastic. They added electrical outlets to the interior and exterior of my home and installed an exterior light. Chase was very thorough with the estimate he provided me and completed the job in the time he said it would take. I would definitely hire them again for any future jobs and I highly recommend them to anyone else."

"Paul came over early in morning and gave us a bid to install two ceiling fans and a bathroom light fixture. He said the fee would be $180 for each fan and $80 for the light fixture plus an $89 service fee. Bid seemed high, but he said he could do the work that day, so we went ahead. He was very professional and informative. Did the work efficiently and was courteous. The fans and lights work well."

Generator Install questions, answered by experts

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.

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.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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.
