Ductless air conditioning systems, known for their efficiency, also raise questions about their noise levels. Understanding how noisy these systems can be is essential for homeowners.

Noise Levels of Ductless Air Conditioning Systems

• General Noise Levels: Ductless AC systems typically operate at 19-48 decibels (dB).
• Indoor Units: Usually quieter, ranging from 19-30 dB.
• Outdoor Units: Louder, often between 45-55 dB and may reach up to 65 dB for some models.

Common Noise Sources

• Compressor: The main source of noise is from the compressor located in the outdoor unit.
• Fan Noise: Indoor and outdoor fans contribute to overall sound levels during operation.
• Vibration: Some noise may originate from vibrations transferred through walls or structures.

Comparison of Noise Levels

Advantages of Lower Noise Levels

• Better for sleeping environments.
• Less intrusive during day-to-day activities.
• Allows for quiet relaxation and entertainment.

How to Reduce Noise from Ductless AC Systems

• Proper Installation: Ensure that the units are installed correctly to minimize vibrations.
• Location: Place outdoor units away from windows and living areas.
• Use of Noise Barriers: Install sound barriers around the outdoor unit.

Noise Level Ratings

• ASHRAE Standard: Guidelines on acceptable noise levels in residential cooling systems.
• Energy Star Ratings: Acknowledges quieter units for their efficiency and low operation sound.
