Our Services

Residential

As a family-owned business that has been delivering fuel to New York City residents for several generations, residential service is in our genes here at Blue Diamond. These days, the residential landscape of NYC is seeing a lot of changes, as brownstones and tenement housing make way for luxury apartments and high-rises, but as always, Blue Diamond continues to evolve with the times, working with building owners, property managers and tenants to keep the "home" in home comfort services. 

Commercial

Home to the New York Stock Exchange, the Fifth Avenue Shopping District, and millions of local businesses, New York City is the world's commercial epicenter. As a proud Brooklyn-based business, Blue Diamond is happy to support others in the City's business community by offering expert consulting, procurement and benchmarking services, as well as utility audits and a range of other tools that help companies succeed in this competitive commercial environment.
