Key Features Explained

Two-Stage Compressor

Unlike standard single-stage compressors that run at full capacity all the time, the Infinity 24ANB1 operates at a lower stage most of the time for greater efficiency, quieter operation, and more consistent indoor comfort. The higher stage engages only when additional cooling is needed, improving performance and reducing energy consumption.

Smart System Compatibility

This unit integrates seamlessly with Carrier’s IdealHumidity™ System for enhanced moisture management and the Infinity® Touch Control thermostat, which offers zoning capabilities, remote system management, and detailed energy reporting.

Enhanced Air Quality

The Infinity 24ANB1 can be paired with Carrier’s Air Cleaner purifier, built-in ventilator, and UV lamp to reduce mold, bacteria, and other airborne contaminants—helping maintain a healthier indoor environment.

Durability and Protection

Designed for longevity, this model features:

  • A galvanized steel cabinet with baked-on powder coat finish

  • WeatherArmor™ protection for corrosion and dent resistance

  • A louvered coil guard and filter drier to protect key components from moisture and debris

Quiet Operation

Carrier’s Silencer System II™ reduces vibration and mechanical noise for whisper-quiet performance, even during high-demand cooling cycles.

Warranty Coverage

  • 10-year limited parts warranty (including compressor) with registration within 90 days of installation

  • 5-year limited parts warranty if not registered

  • Optional labor warranty available for purchase

Comparable Models by Carrier

1. Infinity 24ANB1 vs. Performance 24ACC6

The Performance 24ACC6 is a mid-range alternative that costs around $2,000 less. However, it has a single-stage compressor and a lower SEER rating (up to 16), making it less efficient and not as effective in humidity or temperature management.

2. Infinity 24ANB1 vs. Infinity 24ANB7

Both models belong to the Infinity series, but the 24ANB1 excels in energy efficiency (up to 21 SEER), while the 24ANB7 offers enhanced corrosion protection—ideal for coastal environments within 20 km of the ocean.

3. Infinity 24ANB1 vs. Infinity 24VNA0 (with Greenspeed® Intelligence)

The Infinity 24VNA0 is Carrier’s top-tier model, featuring a variable-speed compressor, Greenspeed® Intelligence, and a SEER rating up to 26. It provides unmatched comfort, efficiency, and noise reduction—along with a three-year labor warranty not included with the 24ANB1.

Final Verdict

The Carrier Infinity 24ANB1 is a standout option for homeowners seeking luxury-level performance, energy efficiency, and quiet comfort. While discontinued, it remains one of the most advanced two-stage air conditioners Carrier ever produced and is still worth considering if available through authorized dealers.
