Diversified HVAC Services, Inc. offers great commercial and residential HVAC/R (heating, ventilating, air conditioning, and refrigeration) services and standard goods to the better Washington, DC and Baltimore Metro regions, including Maryland and Virginia.
Diversified HVAC Services, Inc. was started on April 1, 1990 with a total staff of two people, C. E. Mullaney III and B. E. Dawes, each having 50% of the organization. Their objective was to become self-employed with adequate money, development, and future protection by the sale of service and installation in every region of the HVAC/R business. Mr. Dawes left the firm in August 1997 while Mr. Mullaney kept the organization running. Mr. Mullaney began in the HVAC company in 1965 in an entry-level position and progressed to senior mechanic, then into guidance, technology, sales, ownership and operations manager of the big firm, and finally into ownership of the organization.
In February 2007, the everyday operations of the organization were taken over by Chuck Mullaney IV together with service administration of field operations being assumed by Andre’ Charron. Chuck IV has been in the HVAC business since 1990 when he began as a helper with Diversified. Andre began his HVAC profession in 1995 after exiting the US Naval service and then attending HVAC trade school. He joined Diversified in October of 1997 after meeting Chuck IV at the Air Conditioning Contractors of America (ACCA) Apprenticeship system. Together with Chuck III, they hope to continue the success of Diversified HVAC Services, Inc. while applying the principles that have prepared this firm a success from day one.
It is Diversified’s continuing objective to offer its clients with all the right, reliable, honest, standard, and much priced product possible, and to supply its employees long-term employment with fair income, job safety, development, and training with as several benefits as possible.
