I'm a newbie to United. I just had my first annual HVAC tune-up from United. My tech was Eli Henley, and I'll be asking for him again next year. Eli was friendly, professional, on time, clean, tidy, knowledgeable, considerate, just a pleasure to do business with. If Eli is indicative of the types of technicians United has on its team, I'll be a long-time customer! Awesome work, Eli!!!
