Carrier Infinity® 19VS Air Conditioner

Up to 19 SEER
Variable Speed
Carrier's First Variable Speed Compressor

The Carrier® Infinity® 19VS air conditioner is quite the product, and we had to have it on our featured list. It’s the smallest air conditioner out there (as of 2014) with a variable speed compressor. So why does that matter? The compressor can run at 5 different stages, and can hum along at only 25% capapacity which is great for comfort, air quality (due to more filtration), humidification and efficiency control. So why does the low capacity running ability help with humidity? Because the longer an air conditioner runs the more humidity is removed. If your A/C only runs for 10 minutes at a time, you’re going to have higher humidity.

Additional info on the Carrier Infinity® 19VS Air Conditioner

The Infinity 19VS is different in a lot of ways. It offers variable-speed compression that can step down in 5 stages to as low as 25% of its capacity. That’s huge from a comfort perspective. The ability to run in lower speeds most of the time makes it quieter and more adept at removing humidity and keeping temperatures even. Plus, those lower speeds are the sweet spot for the unit’s best efficiency levels and for getting the most benefit out of other systems you might have like an air purifier because of more constant air flow through the system.

And, it’s seldom you can upgrade your system a component at a time. Most often, the leap to higher efficiency and better comfort via a communicating system for that home you love can mean you have to deal with the cost of a whole system even though only your AC has called it quits. The Infinity 19VS  could change that for you. Your Carrier® expert can help you determine if it can work with your existing indoor unit so you can upgrade in steps.
