What’s the Best Type of New AC Compressor?

When you need to replace the compressor in your air conditioner unit, you might wonder what kind you should choose. You want to select a compressor that will perform well and keep your building cool

However, you also may want it to lower your utility bills and not make a lot of noise while it functions. You can decide what type of air compressor is best for your building by learning about the available models.

Centrifugal Air Compressor

A centrifugal air compressor uses centrifugal force to move around refrigerant in the unit. It uses this force to pull in the coolant before rapidly spinning it with the impeller in order to compress it.

A centrifugal compressor is ideal for using in extra large HVAC systems. If your building uses a large air conditioner unit, you may decide that a centrifugal air compressor is right for your needs.

Rotary Air Compressor

A rotary air compressor can be the perfect choice if you are concerned about noise. When you want a quiet air compressor, the rotary model may suit you well because it:

  • Is small and quiet
  • Contains a shaft with several blades attached to it
  • Pushes coolant through the cylinder while compressing it at the same time


If you prefer your air conditioner function as quietly as possible, you could reduce the noise level without sacrificing the service of the unit by installing a rotary air compressor in it.

Screw Air Compressor

The screw air compressor has a reputation for being reliable and efficient. It is typically used in large buildings where substantial amounts of air need to be continuously cooled.

The screw air compressor has two large helical rotors that move the air in the unit from one end to the other. When the air moves through the compressor, the space gets smaller and the air gets compressed.

Reciprocating Air Compressor

The reciprocating air compressor is perhaps the most popular model available today. It has a piston that moves air up and down inside of the unit’s cylinder.

As it moves the air down, it creates a vacuum that sucks in refrigerant. As the air moves up, the gas compresses and moves into the condenser.

These models are the most common types of air compressors on the market. You can find out more about your choices by calling 408-295-2182 today.
