The Bottom Line

Carrier’s Infinity 19VS 24VNA9 is a premium air conditioner that comes at a premium price, but if it’s in your budget, then you'll get years of reliable cooling performance from this model.

It has five stages of operation, so it can run at lower speeds for longer periods to maximize your indoor comfort and energy savings while eliminating temperature swings. But when the mercury starts to rise, it also has the higher stages of operation to keep up with your cooling demands.

Along with having a great efficiency rating, excellent temperature maintenance capabilities, and superior humidity control, the 24VNA9 can also be paired with other technologies, like Carrier’s Infinity System Control, to further enhance performance and comfort.

Another great thing about the Infinity 19VS 24VNA9 is the inverter, which uses data like humidity and indoor/outdoor temperatures to make adjustments to the cooling output to match your comfort requirements.

The system can also ramp up to increase its cooling output so you don’t feel any temperature changes inside when the weather changes outside.

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

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 the average cost in Canada for this model is between $4,500 and $6,000.

There will be certain compromises with the lower price, including a slightly lower efficiency rating of 17 SEER, a less advanced single-stage compressor, and fewer technological compatibilities. For example, the Performance model doesn’t have the inverter that the Infinity model has, and it’s not compatible with the Infinity System Control.

That being said, if you're not interested in the additional bells and whistles, then the Performance 24ACC6 is still a highly efficient air conditioner that should be powerful enough to cool most homes in Canada.

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 Infinity 24VNA9 offers, such as the protective features, some of the sound-reducing technologies, and warranty terms.

The major difference is the Comfort 24ABC6 has a single-stage compressor, so it’s slightly louder, not as efficient (SEER 17), and not as advanced with temperature and humidity control. It also lacks the Infinity System Control compatibility and the inverter.

Nonetheless, the Comfort model falls into Carrier’s lowest price range even though it’s similar to many of their mid-range offerings in terms of compressor style and efficiency rating, so it’s a good option for Canadian homeowners who want the Carrier name on a smaller budget.

Model Comparison by Tier: Infinity 24VNA9 versus Infinity 26 with Greenspeed® Intelligence 24VNA6

The Infinity 26 is Carrier’s top-of-the-line air conditioner, so it’s the most expensive, the most efficient, and the most sophisticated.

It has a variable-speed compressor, so rather than having only five speeds, it can make incremental adjustments to the cooling output, operating anywhere between 25 and 100 percent capacity. Compressors like this are highly efficient, extremely quiet, and great at managing humidity and eliminating hot/cold spots.

The Infinity 26 has a whopping 26 SEER, though this is generally considered to be far more powerful than Canadians need during our shorter and milder summers (compared to places like the Southern States).

Another feature of the Infinity 26 is the additional 10-year replacement warranty, whereby Carrier will give you a new air conditioner if the Infinity 26’s compressor fails in the 10-year coverage period.

When you pair the Infinity 26 with the Infinity System Control, you unlock Greenspeed Intelligence, a technology that further improves the efficiency and performance of the air conditioner.
