Understanding What Different Noises Mean
AC noises are the system trying to tell you something. A brief gurgling sound during startup or shutdown is normal refrigerant settling, not a problem. A persistent rattling during operation is loose hardware. A high-pitched squeal is a mechanical issue that will worsen. Knowing the difference helps you prioritise.
- Brief gurgle or click during startup/shutdown: normal refrigerant flow, ignore it
- Persistent rattling or vibration: something is loose, needs investigation
- High-pitched squeal or grind: mechanical issue, switch off and call a technician
- Hissing sound: possible refrigerant leak, switch off, ventilate, call immediately
Diagnosing Indoor Unit Noises
Most indoor unit noise problems are caused by loose filter panels, debris in the fan housing, or the fan blade itself becoming unbalanced after debris impact or moisture damage during monsoon.
- Rattling during operation: check that the filter panel is firmly seated and latched
- Chattering noise: small object, insect, piece of debris, in the fan housing; needs cleaning
- Squealing from indoor unit: fan motor bearing failing, needs professional replacement
- Dripping sound: blocked drain causing water to pool and drip, clear the drain pipe
- Low rumble or vibration: indoor unit mounting screws loose, tighten wall bracket screws
Diagnosing Outdoor Unit Noises
Outdoor unit noises are often easier to identify because the unit is accessible for visual inspection. In Goa, monsoon debris, leaves, twigs, small stones, is a common cause of sudden noise after the rains.
- Rattling from outdoor unit: debris lodged in fan grille or fan blades, clear after switching off
- Vibration noise: anti-vibration mounts degraded or unit base unstable, tighten or replace mounts
- Loud thud on startup: flooded compressor or liquid slug, serious issue, call technician
- Persistent grinding: compressor bearing or fan motor bearing failure, call technician promptly
- High-pitched hiss: refrigerant leak, switch off immediately and contact Aermac
Noises That Mean Switch Off and Call Immediately
Most AC noises are inconvenient rather than dangerous. However, some indicate immediate risk of serious damage or safety concern. When you hear these, switch the AC off at the breaker and call a technician before restarting.
- Hissing or bubbling: refrigerant leak, do not restart the unit
- Loud bang or thud: possible compressor damage, do not restart
- Burning smell with any noise: electrical issue, switch off at breaker, call immediately
- Grinding or screeching that started suddenly: bearing failure in progress, stop use immediately

Is it safe to run a noisy AC until my Goa technician can visit?
It depends on the noise type. Minor rattles and drips can usually wait 1–2 days. Grinding, squealing, hissing, or burning smells should not be run at all, switch off and call Aermac for priority assistance. Running a faulty unit risks turning a minor repair into a major one.
