When considering a through-the-wall air conditioner, noise level is one of the most important factors for ensuring long-term comfort in bedrooms, offices, and living spaces. The Amana 9,300 BTU Through-the-Wall AC (PBC093J00AA) is known for its quiet operation, but what does that mean in real-world conditions?
This comprehensive guide will cover:
✅ How AC noise is measured and what decibel ratings mean.
✅ Real-world noise comparisons.
✅ Features that make the Amana unit quieter.
✅ Installation factors affecting noise.
✅ Tips for further reducing noise.
✅ What to expect during day and night operation.
🎚️ 1. Understanding AC Noise Ratings
What are Decibels (dB)?
Noise levels are measured in decibels (dB). A lower dB indicates quieter operation:
-
30 dB: Whisper
-
40 dB: Library
-
50 dB: Moderate rainfall
-
60 dB: Normal conversation
Most room air conditioners operate between 45-60 dB depending on fan speed, cooling mode, and distance from the unit.
Learn more about decibel levels from the CDC's Noise Guide.
🪟 2. Typical Noise Levels for Through-the-Wall ACs
Through-the-wall units typically operate within 48-58 dB under normal use. Factors influencing noise include:
✅ Fan speed settings.
✅ Compressor cycling on and off.
✅ Room acoustics and installation.
✅ Maintenance and cleanliness of the unit.
For additional noise comparisons, see Consumer Reports AC noise testing.

🧩 5. Installation Factors Impacting Noise
Even a quiet unit can be noisy if improperly installed. Key factors:
✅ Wall Sleeve Fit: Ensure your unit is installed in a properly sized, insulated sleeve to minimize vibrations.
✅ Level Installation: An uneven installation can cause rattling and excessive vibration.
✅ Seal Gaps: Unsealed gaps amplify outdoor noise and vibrations.
✅ Secure Mounting: Loose mounting hardware creates additional noise during operation.
See AC installation guide for tips on installing your AC quietly.
🌙 6. Real-World Noise During Day and Night
Daytime Operation:
✅ At medium to high settings, noise blends with background activities, making it barely noticeable.
✅ Suitable for living rooms and home offices where moderate white noise is acceptable.
Nighttime Operation:
✅ Low fan settings maintain comfort while minimizing noise.
✅ Sound levels around 48-50 dB are suitable for light sleepers, comparable to a whisper or white noise machine.
If you are sensitive to sound, consider pairing your AC with a white noise app to mask compressor cycling sounds at night.
🪛 7. Tips to Reduce AC Noise Further
✅ Use Low Fan Speeds: Unless rapid cooling is needed, lower fan speeds reduce noise.
✅ Maintain Your AC: Clean filters and coils to prevent the fan and compressor from overworking.
✅ Check for Obstructions: Remove debris near the exterior of the unit to allow free airflow.
✅ Add Curtains or Acoustic Panels: Soft furnishings absorb and dampen sound within the room.
✅ Check for Loose Screws: Periodically tighten any accessible mounting hardware.
