"Blackwell provides fast and great service! I have had them out to my house now twice and am very happy. The last time we were installing a fan when the husband fell off of the ladder and broke his wrist on a Thursday. I had family coming in that weekend and Blackwell made it out on Friday in time before family arrived. Prices are fair and everyone at the company is professional, honest and nice. Highly recommend."

"Flawless Work and Unmatched Attention to Detail! Chris and his team are truly the best in the business! From start to finish, their professionalism, communication, and craftsmanship were top-notch. Chris has an incredible eye for detail. His precision and thoroughness are next-level. You can tell he takes real pride in his work; everything was perfectly measured, aligned, and finished with care. I absolutely love that Chris is a little OCD (in the best way possible!) because it means nothing gets overlooked. He treats every project like it’s his own home, and the results show it. The whole team was efficient, respectful, and left the space cleaner than when they arrived. If you want electrical work done with true expertise and perfection, call Chris and his team! you won’t find better!"

Generator Install FAQs, answered by experts

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.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

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. 

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.
