How Two-Stage Compressors Work: Pros & Cons

A two-stage compressor is a single unit that houses two compressors offering two different speeds or stages of air conditioning:

1. High speed for any type of severe weather
2. Low speed for calmer weather and more moderate temperatures

A major benefit of two-stage compressors is that they have the versatility to handle mild to extreme weather. Some other pros associated with two-stage compressor include that they:

• Provide greater comfort and efficiency, when compared to a single-stage compressor
• Are energy efficient because they can handle almost any temperature with the low speed, meaning they turn on and off less often
• Removes moisture from the air, which is perfect for the more humid regions

On the downside, a con associated with two-stage compressors is that they can be expensive to repair or replace if they break down and are no longer under warranty.
