Experience was the key to fixing this issue and Sean definitely knew what he was doing. We've been with Heart for over 25 years, have met many of your techs, for the most part have always had very good service. Most of your employees are personable, clean, and knowledgeable. I had never seen Sean before, so I assume he is new or new to my area. He did an outstanding job, wore a mask the entire time, and worked efficiently. I hope he will continue to service us whenever possible.
