"Last Monday, Nov. 3, I had some major surgery done on my GENERAC generator. It was time for "Super Maintenance" and your service man did a SUPER job! His name is Joe and he did a great job servicing my machine. He arrived on time and went right to work. He changed the oil and oil filter, put in a new battery, adjusted the valves, put in a new air filter, and even cleaned the top of the generator. All this while i looked over his shoulder and asked questions, lots of questions. I am impressed with Mr. Joe. He is very knowledgeable about your products, well spoken, and easy to talk to. It took him less than an hour to complete his work, despite my constant jabbering. He's a KEEPER! Thank You Trinity, And Thank You Joe! Paul O Weller Trinity Client"

"Jason installed doorbells at 2 doors. There were no functioning doorbells when I purchased this house 5 years ago. Various contractors warned me of the difficulty and expense of hardwired installations, making me put off the project. Wireless doorbells were unreliable. I was encouraged by James, who did my annual electrical maintenance, and scheduled the work for me. Jason did a fantastic job by creative thinking to avoid the difficulties I'd previously been warned about. He did the job quickly, neatly, and very successfully. I am thrilled to have working doorbells for the first time in 5 years!"
