"He was fabulous and did a great job. It was a 20kw generator. He was very professional and came in uniform. He was thorough in discussing my options. He was able to install this in my basement instead of hanging it outside. The main reason why I'd recommend him so highly is that the unit I have is a big generator. I have it setup to run on propane. It turned out that the gas company did not lay the line within the county codes. Jim caught that and notified that. They argued with him, but the county came out and determined that it was potentially dangerous. The gas company had to redo the installation for free. He could of just finished the installation, and I would not have known the distance."

Generator Install FAQs, answered by experts

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.

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. 

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

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