In Depth Review

Infinity 24VNA9 Product Specifications:

• Compressor: Variable-speed
• SEER: Up to 19
• ENERGY STAR® certified: Yes (select sizes)
• Decibel rating: As low as 56
• Tonnage: 2 to 5 tonnes

Features Overview

Variable-speed compressor: The 24VNA9 is equipped with a variable-speed compressor that has five stages of operation, so it can operate consistently at a lower speed to control humidity and keep your home at the perfect temperature all the time. Not only does this increase efficiency and lower your energy bills, but it also reduces temperature fluctuations. Then, when the weather gets particularly hot or humid, the system can ramp up to increase its cooling output so you don’t feel any temperature changes inside.

IdealHumidity System compatible: The IdealHumidity System provides independent humidity control in your home to ensure maximum comfort and energy savings. When you pair the 24VNA9 with the IdealHumidity System, your cooling system will maintain the ideal temperature and moisture level in your home throughout the year, and your air conditioner won’t have to work as hard to keep you comfortable, so this system can save you money and increase the longevity of the 24VNA9.

Quiet operation: The 24VNA9 has many sound-reducing features to ensure it’s one of the quietest air conditioners on the market, and these features include the Silencer System II that reduces vibrations, a soft start system, special forward-swept fan blade design, a compressor sound blanket, and a pressure equalizer valve.

Custom comfort settings: You can pair the 24VNA9 with the Infinity System Control smart thermostat, enabling you to create separate zones with unique temperature management settings, which will further increase your comfort levels and energy savings.

Comparable Models by Carrier

Model Comparison by Price: Infinity 24VNA9 versus Performance 24ACC6

The Performance 24ACC6 is one of Carrier’s mid-range offerings, and you could save well over $1,000 by opting for this model in favour of the premium 24VNA9. There will be certain compromises, however, such as a lower efficiency rating, a less advanced compressor, and fewer technological compatibilities.

Model Comparison by Features: Infinity 24VNA9 versus Comfort 24ABC6

The Comfort 24ABC6 may be one of Carrier’s low-tier models, but it shares a number of the features that the 24VNA9 offers, such as the protective features, sound-reducing technologies, warranty terms, and air quality control. The major difference is the Comfort 24ABC6 has a single-stage compressor, so it’s slightly louder, not as efficient, and not as advanced with temperature and humidity control.

Model Comparison by Tier: Infinity 24VNA9 versus Infinity 24ANB7**C

The 24VNA9 and 24ANB7**C are both premium models and have very similar specifications and features, but the 24ANB7**C has been specifically engineered to withstand harsh coastal environments and the corrosion they can cause.
