"Dustin & his crew were PHENOMENAL! In a world where you have to micromanage, check in and hope and pray people show up, Three Ridges is a beacon of hope! We had a catastrophic emergency, where the power was literally ripped from the cabin by a tree. These guys, were prompt, respectful, handled everything from A-Z, permit, power company and even came back to make sure everything thing was reconnected after the power company came out to restore the power. I would give 10 million stars. We will ONLY use 3 Ridges from now on, and we will tell everyone we know. Thank you Three Ridges!"

Generator Install questions, 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.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

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. 

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

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.
