Single-Stage, Two-Stage, and Variable-Stage: What Is the Difference?
If you’re shopping for a replacement AC or heat pump, you’ve probably heard about these options. But what are the differences between single-stage, two-stage, and ...
Built on Willis Carrier’s invention of modern air conditioning in 1902, Carrier is a world leader in heating, air-conditioning and refrigeration solutions. We constantly build upon our history of proven innovation with new products and services that improve global comfort and efficiency.
Carrier’s Comfort Series are reliable and efficient, as well as budget friendly. They provide comfort by working in one speed that kicks on and shuts off within a couple of degrees of your thermostat setting. With this on-off approach, you can tell when it’s coming on because of the system’s rev-up followed by air starting to blow through the vents at full speed. Once this type of unit hits the proper temperature, it shuts down and then starts the cycle over again. These units will provide years of reliable service, while meeting minimum government efficiency levels and your basic comfort level needs.
Carrier Performance Series offer mid-range efficiency and usually have two-speed fans. These units generally run mostly at the lower speed. The low speed fan makes far less noise than a high speed fan, but the system still cycles like the good units. Because it spends more time in low operation, it is more efficient to operate and it’s able to keep the room temperature more even throughout the day by allowing a constant flow of air into each room.
Like the name states, Carrier’s Infinity Series is the best option in terms of comfort, efficiency, humidity control and noise levels. These units spend 90% of their time operating at very low speeds, meeting the exact requirement for the room. This makes these units the most efficient to operate, with the quietest noise levels, the most even room temperature, and the best humidity control. Once you experience this type of comfort level, you’ll feel what makes this the best option available.
