"Working with Smith Power Group, Inc. was a very rewarding and mutually beneficial experience. The owner, Carlton, sat with us and explained the entire process and answered all of our questions. The office kept us informed concerning the necessary paperwork, permits, etc. On the day of installation the crew arrived on time and proceeded to install our generator without issues. We highly recommend SPG."

"Ken was hired to put a sub-panel in the garage, but he notice that rain was getting in the main panel. I hired him to replace the service coming down the side of the house, through the meter box and then the main panel and sub-panel. He did a great job. He was clean and neat and he worked around my work-from-home needs to electricity. He did the service and main panel on a Saturday and I had minimal power disruption. He is friendly and knowledgeable. I would definitely hire him again."

Generator Install questions, answered by experts

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.
