Carrier AC Units, in this case, the Infinity 21, are considered the best central air conditioners because they are quiet, preserve energy when only mid-level heating and cooling are required, and are built to last. Of course, they have a higher than normal SEER rating, but a trained professional should tell you if that meets your home’s needs or not. Read on to learn more about the Infinity 21, and don’t forget to also check out other best-selling air conditioners as well.

Why We Like It – Carrier Central Air Conditioner

The Carrier Central Air Conditioner, specifically the Infinity 21 Central Air Conditioner, is great for homeowners looking for a good value on their heating and cooling needs. The Infinity 21 Central Air Conditioner comes with fantastic climate control and at a lower cost than other Carrier Series Brands. For comparison with another brand, you may also want to check out our Cake Arctic Air Portable Personal Evaporative Cooler review.

  • Quiet
  • Energy Star Compliant
  • High Quality and Built to Last
  • High SEER Rating
  • Doesn’t Use True HEPA Filters
  • Marketing Drives the Price of the Unit Up


Unlike the Bryant Legacy air conditioner, Carrier Air Conditioners contain a seasonal energy efficiency rating of 21. Of course, these ratings are variable and an HVAC specialist should be able to determine what SEER unit is right for you. Residential units generally need 14-16, so 21 may be a little high. Check out the Amana Air Conditioner for something lower. The Carrier is only 65dB though, so that’s a plus. Yet, the Evapolar portable air conditioner is only 10dB, which is super quiet. Compare that to the Coleman Central Air Conditioner that’s a high-efficiency budget-friendly unit.

Energy Efficiency

Carrier Central Air Conditioners are energy-efficient models because, when air conditioning demand is low to moderate, they run at 70% capacity. Not only does this amount to energy savings, but a quieter unit too. If you want to shop around, another high-efficiency model you can check out is the Goodman Air Conditioner.


System Carrier HVAC Systems offer MERV 15 filtration with all Infinity Series models. The advantage of MERV 15 filters is that they trap more dirt and debris than most other filters. However, be aware that these are not True HEPA filters so they won’t stop as many small particles as quality air purifiers will. Unfortunately, not even the Carrier Comfort Series, which is single-stage, or the Performance Series uses True HEPA Filters.


Carrier Infinity Series Central Air Conditioning System shows few service records and fewer repair issues than most other brands which is an indicator of their quality. In fact, the Infinity Series is rated to last 20-25 years. A Carrier Installer must also receive special training from Carrier to install the unit properly. Thus, you know things like the heat pump and the boiler will be installed correctly. Can the Goodman GSX13 say that?


Air Conditioner prices are largely determined by installation costs. As such, it’s hard to give a definitive answer here on how much a Carrier Central Air Heating Cooling System will cost. However, we can tell you that it will be slightly more expensive than most concerning Carrier’s great reputation but also because they spend a lot on marketing, which they have to recoup somehow.

Carrier Central Air Conditioner Wrap Up

With Carrier’s impeccable reputation and Carrier-certified instructors installing your unit, it’s easy to see why the units will cost a little more. Maybe I’m overthinking it, but I just can’t justify marketing costs being part of that price, though. But if an air conditioner will last for upwards of 20 years then I’ll definitely, at least, have a look.
