I posted a negative review of Black Diamond earlier today. While I am disappointed that there was a lot of miscommunication. The company is coming out to rectify the situation. Tony the Supervisor was very agreeable to get the job done and done to the customer’s (me) satisfaction. I would definitely recommend Black Diamond to friends and family.
Beth – Grayslake, IL
They were prompt and commicated very well. Technician was very good. Price was quite high for simple motor replacement. Capacitor price was outrageous at $166.
