Variable Speed Compressor Sounds

Topics:

• Noise from unit compressor
• Compressor makes loud or high pitch noise when turns on
• Sound from unit turning on is loud

Answer:

The variable speed compressor always starts at high speed, then will slow down after approximately 5 minutes.

• On high speed, the compressor may emit a high pitched whining sound. This is normal.
• Replacing the compressor with another variable speed compressor will not eliminate this sound.
• Variable speed compressors are more energy-efficient and overall produce less noise than standard compressors.
• Some people are more sensitive to the pitch some compressor speeds create.
• Replacing the compressor or product is not a resolution to variable speed compressor noise complaints, as each unit with this type of compressor may produce the same sounds.
