Made a call and David gave me a window of when he would show up the same day. He called to let me know he was 5-10 minutes away, showed up and listened to the problem. He did a quick diagnostic and revealed the issue which he clearly and concisely explained to me along with the solution. He went about his business and fixed the problem - quickly, cleanly, precisely, and inexpensively. He then gave me some maintenance pointers to ensure the longevity of the fix. Good thing I made this call! Highly recommended!
