Infinity® Series


If there’s an air of superiority to these units, it’s because they’re the quietest, most efficient models Carrier makes. Built for total home comfort, Carrier Infinity series central air conditioners offer an enviable SEER rating of up to 21. Combine it with the innovative Infinity® control for the highest degree of comfort management.

Extra-Consistent Comfort

Standard systems mindlessly blast cooled air at one speed before shutting off, which can lead to widely fluctuating temperatures. The Infinity® series air conditioner with a two-stage scroll compressor, when properly matched with a Carrier® compatible indoor unit, runs on low-stage up to 80% of the time to maintain consistent comfort. The two-stage operation also contributes to reduced energy usage, helping achieve up to 21.0 SEER cooling efficiency.

Environmentally Sound Refrigerant

Carrier led the industry by incorporating non-ozone-depleting Puron®refrigerant into air conditioners back in 1996. Millions of Puron refrigerant units in operation today are a testament to the reliability, durability and enduring quality of these products.

Maximum Comfort and Peace of Mind

By combining the intuitive Infinity® Touch Control with the Infinity control board in the air conditioner itself, Carrier puts maximum comfort at your fingertips. When installed as part of a complete Infinity system, you control comfort schedules, temperature, humidification, dehumidification, fan speeds and more, all from one easy-to-use control on the wall in your home. This system monitors air conditioner functions, makes adjustments to maximize performance and provides maintenance reminders on the Infinity Touch Control.

Quiet Operation

Infinity two-stage air conditioners quietly cool your home with sound levels as low as 65 dBA. Our exclusive Silencer System II™ features a silencer top, integrated fan motor, forward-swept fan blades, compressor vibration isolator plate, sound hood, and split-post compressor grommets to help deliver quiet operation by maximizing airflow and minimizing vibration.
