Ashlee from Cotti Johnson just installed the last portion of our new Generac generator. She was prompt, courteous, respectful & had the knowledge necessary to assist this old tech challenged person. I now understand the basics to utilize this generator. Thank you Ashlee & Cotti Johnson for your assistance throughout this entire process.
