"We have used and continue to use ThunderBird Power, specifically Thomas Tumlinson for all our electrical needs. To date that includes wiring a 900 square foot shop, updating a 200 amp panel, adding a generator switch to an existing panel and changing out every switch and outlet in an investment property. Thomas and ThunderBird will always be our first call. We recommend Thomas to all our friends."

"AP&L is very professional, knowledgeable, clean, and met the requirements of our build schedule. We built a 3800 sq ft contemporary home with back up generator. Very knowledgeable and assisted with lighting design and low volt controls for window treatments and security. Pricing was competitive and crew was onsite as scheduled with all materials need to complete the project. Highly recommended!"

"Much better than expected - some slight delays waiting for parts, but for the most part a timely process from start to finish. Would like to complement the installers (Eric and Chance) for their knowledge, problem-solving skills, positive attitude, work ethic, and overall attention to detail."

Generator Install questions, answered by experts

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.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

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. 

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

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.
