Electrical Problem

Called BD about 10:00 AM, got an appointment for same day at 2:00 PM Daniel knew exactly what the problem was and he fixed it in about 10 minutes. Well worth the price as I am scared of electricity! Glad to have the pro on the job.

Professionals with quality service

Recently had two experiences with Black Diamond. Michael M. serviced our dead A/C and Keo V. came the following week to do the annual checkup on the AC/Furnace and Hot Water heater. Both gentlemen were ON TIME, efficient, informative and polite. I am not accustomed to service people arriving ON TIME...that was refreshing!

Usual excellent service

Again you have come through, arriving within a couple of hours after my contact with you. There is an axiom in business that never fails: "What every customer wants is the best service and the best product for the cheapest price. The reality is that you can only have 2 of the 3." I choose Black Diamond every time because you deliver the first two every time!
