“I call on LONG because of their responsiveness. I know that they will answer my phone call or email and get back to me with an equipment selection or product information quickly. When it comes to equipment selection they are the first call I make.”

“Travis, I wanted to THANK YOU for saving me this morning. It was way above and beyond of you to come out early on a Sunday morning in the freezing cold and get the heat running. I know that was not technically part of your job description at all, but your willingness to help get our system running correctly through thick and thin speaks volumes to your character and work ethic. Everyone left the class happy, and the heat worked great for the 11 and 4:00pm. Thank you again.
