Frequently Asked Questions

Q: How is the low noise level achieved?
A: Through a combination of optimized compressor mass balance, special cylinder head design for reduced gas pulsation, precision-balanced crankshaft, vibration isolation mounts, acoustic insulation jacket, and low-RPM large-diameter condenser fans.
Q: What does 62 dB(A) sound like in real terms?
A: 62 dB(A) is comparable to normal conversation level or background office noise. It is significantly quieter than standard condensing units which typically operate at 70-78 dB(A).
Q: Can an acoustic enclosure reduce noise further?
A: Yes, our optional acoustic enclosure can reduce noise by an additional 8-12 dB(A), bringing the unit below 55 dB(A). Contact us for enclosure specifications and pricing.
Q: Does the noise reduction affect cooling performance?
A: No, the noise reduction features are designed to maintain full cooling capacity. The low-RPM fans are larger diameter to deliver the same airflow at lower speed and noise.
Q: Is this unit suitable for night-time operation in residential areas?
A: Yes, at ≤62 dB(A) the unit meets most municipal noise ordinances for commercial equipment in residential-adjacent zones. The optional acoustic enclosure provides additional assurance for the strictest noise regulations.
