Rated 4.9 out of 5 stars based on 440 customer reviews

Very competent service. Excellent explanations. Very timely assistance.

Black Diamond had Nick out to our house within two hours of our call. Superior! Not only did Nick do an excellent job in fixing our air conditioner, he also gave excellent explanations and clearly outlined our options. We could not be more satisfied.

Too expensive

I thought the $2.0 price included the vent work. The next day I find out that the vent work will cost an additional $800.00
