"Spencer and Logan O'Brien were amazing to work with. They, and their crew, were competent and trustworthy to be at our home during this construction job. Spencer is a very good communicator and responds to questions and requests in a timely manner. He was able to organize all the needed elements from land preparation to electrical to make the garage happen, leaving us with very little to worry about. We are completely happy with the end product of their labors and love how the new garage fits in with our existing home. We will absolutely look to O'Briens and Sons LLC for future projects around the home. Overall, the experience was professional, timely and a great investment! Thank you for making our garage come to life, Bill and Dierdra"

Generator Install questions, answered by experts

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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. 

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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.
