Hello, my name is Chris Dines and I founded Electrical Construction & Design Incorporated more commonly known as NWI Generator in 2002.

From Our Customers

“Last night the town of Wanatah lost power for 18 hours. While my neighbors sat in their dark homes, I enjoyed heat, light, and peace of mind. I did feel bad about my neighbors, but not enough to invite them all in. This was the first power outage since the installation in May. Well worth it! Thank you!”

Terri K., , Wanatah, Indiana

“Zeroed in on the problem and got it done. The price was also excellent. NWI Generator did a great job! We are so happy with the work that was done.”

Dick S., , Valparaiso, Indiana

“Similar quotes from 2 other companies, but far more professional presentation by salesman/owner. They only do generator installations so they have to be excellent to stay in business. Licensed electricians and plumbers (for gas line modification). Extremely neat and fast installation with complete cleanup after work was done. No company could do it better. One neighbor saw the work and will get the same thing from the same company.”

Don B.,, Crown Point, Indiana

“I just wanted to thank you for your assistance with the purchase and installation of my generator today. I feel comfortable that I’ll be able to weather the storm now! Chris was super too … I enjoyed our conversation about art and building homes. The two guys installing the generator were super too … they worked straight through until the job was complete. No monkeying around! Ha! Please thank all involved for me if you would.”

Joseph R., Crete, Illinois

“Sometimes cheaper is not always better. I always stay away from businesses that require half or some money down. This business was very fair, easy to deal with and very professional.”

Sheryll B., , Hobart, Indiana

“Very friendly, funny and worked hard to get the job completed. Great job!”

Charles A., , Valparaiso, Indiana
