Allied Air Enterprises announces the new 4AC17 single stage air conditioner under the Concord, Ducane and Allied brands, providing an efficiency range of 15 to 17 SEER. Allied Air started production in July 2022, proactively anticipating 2023 regional efficiency requirements in the Southeast and Southwest United States, where new minimum efficiency requirements are moving from 14 to 15 SEER or 14.3 SEER2 under the new testing standards.

According to the 2023 requirements, there is no sell-through period for non-compliant air conditioning units in these regions. This means distributors must have compliant products in stock well before Jan. 1, 2023.
Delivering up to 17 SEER, the 4AC17 unit is built on Allied’s proven design of cooling products. It also achieves compliance without requiring a change to existing indoor system components to ease the burden of this transition, knowing distributors will face another major transition in 2025.
These units reduce energy bills vs. older, less efficient modes they’re replacing, while providing immediate relief when homeowners need it most. ENERGY STAR Certified, the air conditioning units also feature Omniguard Total Corrosion Protection Technology.
Other features include:
- Installation ease – refrigerant valves are placed at the corner of the unit and angled at 45° to help make brazing and gauge port access easier while our all-aluminum Omniguard coil system maintains a copper to brass connection – keeping brazing techniques familiar.
- Single-Stage Scroll Compressor – Reliable single-stage compressors are made from quality materials that are built to provide year-after-year comfort.
- ENERGY STAR certified
- 10-year Limited Warranty on the compressor* and a 10-year Limited Warranty on parts*
