ARI Type Codes

The Air-Conditioning and Refrigeration Institute (ARI) has developed a series of classifications for central air conditioning systems which summarizes their most important features. These type codes are of interest to cooling contractors, but are probably not relevant for the average consumer.

Here is a listing of the codes and their meaning:

  • SP-A: single package air conditioner, air cooled
  • SP-W: single package air conditioner, water cooled
  • RC-A: air-conditioner with remote air-cooled condenser
  • SPY-A: year-round single package air conditioner, air-cooled
  • RCU-A-CB: split system: air-cooled condensing unit, coil with blower
  • RCU-A-C: split system: air-cooled condensing unit, coil alone
  • RCUY-A-CB: year-round air conditioner, remote air-cooled condensing unit
  • RCU-A-CB-O: split system: air-cooled condensing unit, coil w/blower, free delivery
  • HSP-A: single-package heat pump, air source
  • HRCU-A-C: heat pump with remote outdoor unit, no indoor fan, air source
  • HRCU-A-CB: split system: heat pump with remote outdoor unit, air source
  • HRCU-A-CB-O: split system: heat pump with remote outdoor unit, air source, free delivery
