"Mike at MDL electrical went above and beyond the call of duty. We were facing a potential major electrical issue during a very busy evening in the middle of service. He responded to the call and even took the time to stop and check out the issue to ensure our minds were put at ease. He came back the following day promptly and repaired the situation with efficiency and ease. We would highly recommend MDL & Mike and take comfort in knowing we have a reliable electrician to call on! Thank you so much Mike! We appreciate you! Molly & Living Roots Winery Crew"

Customers say: Quick response

"Anthony was very attentive to my project on an old building. He sought out a safe and viable solution to change out an old fuse box and relocate with a new breaker box. He was quick with a response to my request, inspection and quickly gave a solution with a quote. Once I accepted, he scheduled my work right away. He was also prompt on the day of installation and did the work professionally and quickly. I recommend A & A Electric and I would even recommend Anthony to my family and friends. - Pastor Jeff"

"Marlock Electric upgraded our electric service from 100 amp to 200 amp. We were installing solar panels with our new roof, and did this upgrade along with that project. Marlock was recommended to us by the contractor installing the solar panels as a company that would do a very professional job for us - they wanted to be sure the work would be done right to connect the solar system to it. Marlock did an excellent job for us - it was somewhat complicated, but they are experts who knew how to do the work properly. They explained the whole process to us and answered all our questions in a way we could understand. They added extra crew members to make sure the work was done in one day so we wouldn't need to be without electric service overnight. The work was done in a very professional manner, and the site was cleaned up before they departed. We are very satisfied with the service we received from Marlock Electric, and will call on them for any future electrical work we need to have done."

"Jared was amazing with communication and the attention to detail with the installation of the electrical panel was beyond expectation. He gave us exactly what we asked for and more. I would hire him again for any future electrical projects we might have. His team was also highly skilled and talked us through everything they were doing."

Generator Install FAQs, answered by experts

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

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.

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.
