Black Diamond truly says what they are going to do and does it every time. I have been a satisfied Diamond Club member for over 8 years at my last home and now at my current home and rental property. They always show up the same day I call! We recently installed a generator by Black Diamond and while they were here, they let me know I could have my furnace checked that day to beat the winter rush. Wow! I will continue to refer Black Diamond to all my friends and family!
