AAON® HVAC UNITS
MODEL NUMBER NOMENCLATURE

HVAC units are identified by their multiple-character model number that identifies a particular type of unit. Below you will find a partial explanation of the alphanumeric identification code (aka Model Number Nomenclature). Our samples have been simplified to concentrate more on the location of each individual units tonnage and air flow characteristics. This has been done primarily to assist Commercial Building and Home Inspectors, Home Owners Associations (HOA’s), Appraisers, Owners/Operators, etc.
General Directions: (1) Locate the model number your researching. (2) Hover over each grouping to reveal pertinent info for each part of the model number. (Note: Tonnage, Air Flow, kW, etc. are located within the oval/round shaped buttons).
