Phillip did a great job, paying much attention to detail.I could not have asked for a more thorough preventative maintenance visit.
Chris was very thorough, efficient and had a calming personality. I share that because he was totally comfortable with my inquiries and he explained without hesitation! I appreciate his review of my furnace and ducts pertaining to the system with video explanation to reassure me the work was thoroughly done and system was in good health! This was my first experience with my new annual maintenance contract and I'm very happy and look forward to my next service. I'm about prevention so this annual plan seems to be a good fit to my needs! Customer service is also important and Chris is deserving of a shout out!
