Case Studies

N.E.T.R., Inc. offers home and business owners the option to purchase a backup generator outright or on a monthly installment plan that includes ongoing maintenance.
Whichever you choose, our turnkey price includes the generator, installation, electrical and gas fittings, necessary permits, and everything else you need to get started.
Our standard system installation flexible payment plans can be as low as:

• 14 kilowatt generator with a 100 amp auto switch – $170 per month 
• 18 kilowatt generator with a 100 amp auto switch – $195 per month 
• 22 kilowatt generator with a 200 amp service switch – $225 per month
• 24 kilowatt generator with a 200 amp auto switch – $245 per month 

The most common reason for generator failure is a lack of maintenance, regardless of which brand you choose or which contractor completes the installation. That’s why we developed our pay-as-you-go generator installation and service package, so more home and business owners can take the next step in protecting their properties.
Our service allows you to access critical equipment during an emergency or power outage with affordable generators and annual maintenance done for you.

When our technicians service your generator, we: 

• Change the oil
• Replace the oil filter 
• Replace the air filter 
• Test for error codes
• Confirm proper start up, power transfer, and shut down. 
• Perform other routine maintenance.

As authorized Generac dealers and contractors, we’re proud to partner with one of the best brands in the industry. We choose Generac brand generators because they have: 

• 99% success rate
• 5-year limited warranty regardless of hours
• 24/7/365 customer service
• Remote equipment monitoring
• Quiet operation
• Smart controls
• Air-cooling technology

These generators are reliable, affordable, and American-built and engineered to last for many years to come. Other manufacturers often have weak warranties or inferior craftsmanship, all of which can result in the malfunction of the system or even a fire or electrical hazard.
When you work with us, our factory certified technicians and licensed electricians schedule a time and date that works for you to come out to your location and discuss your backup power needs. We’ll go over how much power you need, where you want to put the generator, and any questions that may arise during the installation process. Our team will assess your specific requirements and talk through the different options that may be available to you.
