At EKG (Malaysia) Sdn Bhd, we offer expert compressor noise troubleshooting services for air-cooled chillers, helping you identify and resolve unusual or excessive noise that may signal mechanical or electrical issues. Compressor noise can range from subtle humming to loud knocking, rattling, or screeching sounds—and each type of noise points to a different underlying problem.
Detects early signs of mechanical or electrical failure
Prevents compressor damage and system breakdowns
Reduces vibration, wear, and energy inefficiencies
Improves occupant comfort and system quietness
Supports predictive maintenance and system reliability
Grinding or whining sounds from worn bearings
Humming or buzzing due to electrical faults or voltage imbalance
Knocking or banging from loose internal components or liquid slugging
Rattling or vibration from loose mounts or misalignment
Hissing or whistling from refrigerant leaks or high-pressure conditions
Initial Sound Inspection
We assess the type, frequency, and duration of the noise during compressor start-up, operation, and shutdown. Each sound provides clues about the possible cause.
Mechanical Component Check
We inspect the compressor’s:
Bearings, pistons, or scrolls (depending on the compressor type)
Mounting bolts and base frame for looseness
Shaft alignment and coupling condition
Oil level and quality
Electrical Testing
We perform checks for:
Motor winding resistance and insulation
Voltage imbalance or single-phasing
Faulty relays, contactors, and capacitors
Refrigerant System Assessment
We look for:
Refrigerant overcharge or undercharge
Liquid slugging or flash gas issues
TXV malfunction or expansion valve noise
Noise Source Confirmation
Using acoustic tools and vibration sensors, we isolate the exact noise source and determine whether it’s internal (compressor-related) or external (e.g., nearby components).
Corrective Action & Reporting
Once diagnosed, we provide a full report detailing:
Root cause of the noise
Recommended repairs (e.g., bearing replacement, electrical adjustment, refrigerant correction)
Follow-up actions or monitoring plans
Prevents major system failures from hidden faults
Improves cooling efficiency and performance
Reduces operational noise and mechanical stress
Enhances safety and system longevity
Enables targeted, cost-effective maintenance
Experts in chiller diagnostics and mechanical troubleshooting
Use of advanced vibration and acoustic analysis tools
Experience with scroll, screw, and reciprocating compressors
Fast, accurate identification and solution of noise problems
Full support for repairs, alignment, and preventive maintenance
Unusual noise is more than just a nuisance—it’s often a sign of deeper issues. With EKG (Malaysia) Sdn Bhd’s air-cooled chiller compressor noise troubleshooting, you get quick answers, precise fixes, and long-term peace of mind. Contact us today to schedule a noise inspection.
