Cooper & Hunter Adds Inverter-Driven Omni AC and Alto Heat Pump Lines for Residential Use

Cooper & Hunter has introduced the Omni series of air conditioners and the Alto series of heat pumps, adding inverter-driven options to its residential HVAC lineup, the company said in a press release dated November 11, 2026, in Doral, Fla.

Key specifications

Both the Omni and Alto models are built around inverter compressors that modulate output to match changing heating and cooling loads, a variable-capacity approach the company says helps hold indoor temperatures more steadily while cutting energy use. The two series share the following parameters:

• Six capacity tiers, from 18,000 to 60,000 Btuh
• R-454B refrigerant
• Compact, side-discharge outdoor units
• 24 V communication protocol

SEER2 ratings reach up to 16.0 for the Omni air conditioners and up to 17.6 for the Alto heat pumps, giving contractors a range of efficiency options for different residential applications.

Design and installation

The compact footprints of both outdoor units are aimed at space-constrained sites. Omni units can be mounted on wall brackets, while the Alto side-discharge configuration is designed to conserve outdoor space. According to the press release, these design choices are intended to give installers more flexibility in new builds and replacement projects alike.

Contractor ecosystem

The 24 V communication standard on both series allows pairing with a variety of Cooper & Hunter air handlers and with compatible third-party indoor units that use 24 V controls and R-454B, the company noted. This is meant to simplify system design, upgrades, and replacements for contractors working across brands.
