"I first asked for a quote back in February of 2024. When I received the quote I decided to wait on this project. Then we lost power for 2 days due to a storm. I then decided it was time and contacted the contractor again. He sent me an updated quote and the project was scheduled. It's now installed and I'm very happy with how it turned out. Hopefully it will be a long time before we need to use the generator because we lose our power. But we are ready when it happens. I will definitely use this company again for any electrical jobs that come up. Andrew and his crew were great."

Generator Install questions, answered by experts

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. 

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

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.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
