The Firm

J.A.R. Engineering, Inc. is a Small Business Enterprise (SBE), located in Flemington, New Jersey within Hunterdon County.  Over the years, we have grown into a full service HVAC, Plumbing, Fire Suppression and Electrical engineering firm.  We are committed to quality, detailed and coordinated designs that meet the individual needs of each specific project.  We promote and endorse the use of energy efficient and environmental friendly approaches where possible.


The firm was originally established in 1966 as M. Benton & Associates by Maurice Benton.  Murry’s specialty was HVAC design.  In 1967, Albert R. Pressler joined the firm, adding the specialties of heating hydronics and steam, Plumbing and Sprinkler systems.  Although having diverse project experience, the firm made it’s name through meticulous School House / Educational designs.  John H. Puha joined the firm in 1989.  Robert L. Chittenden joined the firm in 1995.

In 1998, the firm was renamed to J.A.R. Engineering, Inc. after the retirement of Murray Benton.  “J.A.R.” was formed from the initials of John Puha, Albert Pressler and Robert Chittenden.  Al officially retired in 2003.


Every project is completed under the direction of all partners, with one partner in direct oversight of the project at all times.
