The Bottom Line

In-Depth Review

Product Specifications

  • Compressor Type: Two-stage

  • SEER Rating: Up to 17

  • ENERGY STAR® Certified: Yes

  • Sound Level: As low as 67 dB

  • Available Sizes: 2 – 5 tons

Features Overview

The Infinity 24ANB7’s two-stage compressor is the key to its superior comfort and efficiency. It typically runs in its lower stage to maintain steady cooling, reducing temperature fluctuations and improving energy savings. When needed, it automatically shifts to the higher stage for maximum cooling power during extreme heat.

The unit also supports advanced air quality options, including:

  • A built-in ventilator that brings in fresh outdoor air

  • A UV lamp to prevent bacteria and mold buildup on the coil

  • An Air Cleaner system for enhanced indoor air purity

Built for Durability

Carrier designed the 24ANB7 to withstand years of use and harsh weather conditions:

  • Galvanized steel cabinet with a baked-on powder paint finish

  • WeatherArmor™ protection for added resistance to corrosion and damage

  • Louvered coil guard to protect the internal components

  • Filter drier to prevent moisture-related damage

Quiet Operation

The 24ANB7 was engineered for whisper-quiet comfort, featuring:

  • Silencer System II™ components to reduce vibration and mechanical noise

  • A specially designed fan for smooth airflow

  • A sound blanket around the compressor to minimize operational noise

Additional Features

  • Advanced diagnostics system for easy troubleshooting

  • Factory-matched coil to ensure peak efficiency and longevity

  • Uses non-ozone-depleting refrigerant

  • Compatible with Carrier’s IdealHumidity™ System for superior humidity control

  • Works with the Infinity Touch Control smart thermostat for full zoning and system optimization

Warranty Information

Carrier backs the Infinity 24ANB7 with strong warranty coverage:

  • 10-year limited compressor warranty

  • 10-year limited parts warranty

  • Optional labor warranty (purchased separately for service coverage)

👉 To receive the full 10-year coverage, homeowners must register the unit within 90 days of installation. Unregistered units receive shorter coverage periods.

Comparable Carrier Models

1. Infinity 24ANB7 vs. Comfort 24ABC6 — Price Comparison

If you’re on a budget, the Comfort 24ABC6 offers a more affordable alternative. It’s at least $1,000 cheaper, yet still provides ENERGY STAR® efficiency, reliable cooling performance, and the same 10-year warranty. However, it lacks the advanced two-stage compressor and quiet operation of the Infinity 24ANB7.

2. Infinity 24ANB7 vs. Performance 24ACB3 — Feature Comparison

The Performance 24ACB3 belongs to Carrier’s mid-range line. While more affordable, it comes with trade-offs: a lower SEER rating (13), no ENERGY STAR® certification, and a single-stage compressor. This means less efficiency, higher energy use, and reduced comfort consistency compared to the Infinity model.

3. Infinity 24ANB7 vs. Infinity 24VNA0 — Tier Comparison

The Infinity 24VNA0 represents Carrier’s most advanced technology. It features a variable-speed compressor, delivering SEER 20.5 efficiency, Greenspeed Intelligence, and an additional three-year labor warranty. While the 24ANB7 is an outstanding performer, the 24VNA0 offers the ultimate in energy savings, comfort precision, and whisper-quiet operation.

Final Thoughts

The Carrier Infinity 24ANB7 stands out as a premium, high-efficiency air conditioner that delivers exceptional comfort, quiet performance, and long-lasting reliability. Its two-stage compressor provides excellent humidity and temperature control, making it ideal for homeowners seeking dependable, energy-efficient cooling.

Although discontinued, this model remains a top-tier choice if you can find it available — offering Carrier’s hallmark performance and build quality that continues to outperform many newer units in its class.
