Aurum Prodest
Post-install noise usually means vibration, loose brackets, fan imbalance, drain gurgle or duct resonance.
Separate indoor vs outdoor sources. Bedrooms need Quiet mode, clean filters and free pipe clearance.
Outdoor units need solid anchors, anti-vibration pads and wall clearance — not rigid ties to window frames.
Gurgle often needs drain slope; whistling often means pinched lines.
Map the noise: indoor/outdoor, constant vs clicks, cooling-only vs always.
Rattles often need panel screws, dampers and pipe clearance from the chassis.
Drain gurgle needs slope/siphon; whistling often means pinched lines.
After a third-party install, get an independent diagnosis before warranty fights.
Aurum Prodest diagnoses noise and fixes the root cause.
