Cummins-Wagner Co., Inc.

Cummins-Wagner Co., Inc. operates as an air compressor and industrial equipment distributor serving Annapolis Junction, Maryland, and the broader mid-Atlantic region. With a 3.9-star rating compiled from 14 client reviews, the company maintains headquarters at 10901 Pump House Road in Annapolis Junction while operating a secondary location in Salisbury. The company traces its operations to 1960 and maintains employee-owned status, distinguishing it as a 100 percent employee-owned enterprise. Service coverage extends across Baltimore, the Washington DC metropolitan area, Northern Virginia, the Eastern Panhandle of West Virginia, and the DelMarVa Peninsula. The business functions primarily as a B2B distributor serving mechanical contractors, wholesalers, engineers, and maintenance engineers rather than direct residential homeowners.

What distinguishes Cummins-Wagner from standard HVAC contractors is their positioning as a commercial and industrial equipment specialist rather than a residential service provider. The company offers packaged systems including compressed air packages, fuel oil transfer systems, booster packages, heat transfer packages, glycol make-up units, and ultraviolet filtration packages. Their capabilities extend to custom system design, assembly, parts provision, and aftermarket service and repair. Supporting services include precision alignment, preventative maintenance programs, and in-shop repair facilities. The product portfolio covers air compressors, centrifugal and submersible pumps, vertical turbines, cooling towers, boilers, water heaters, and variable frequency drives , equipment lines typically found in manufacturing plants, mining operations, petroleum facilities, and water/wastewater treatment installations rather than typical homes.

Customer feedback reveals mixed service experiences. Reviewer Henry Wang credits technician Brandon with quickly resolving air compressor issues, describing him as professional and patient. Another reviewer, Casey Fitzgerald, worked with Josh Andrucyk in inside sales to get an air compressor operational, praising Andrucyk's patience and guidance. However, reviewer Eddie Gunn reported frustration over credit request handling, stating each representative passed him to another person. Reviewer Tameka Gray described a problematic boiler order experience for a clinic, citing lack of transparency and required repeated follow-ups. These accounts suggest service quality varies depending on the specific department and technician involved.
