LG VRF / VRV System

How this equipment fouls

Each indoor head fouls exactly like a ductless unit — coil, blower wheel and tray — but a VRF installation multiplies that across dozens of heads. Fouling is usually discovered unevenly, because heads in kitchens, gyms or high-occupancy rooms load far faster than the rest.

Common failures

• Individual indoor heads losing capacity from coil and blower fouling
• Condensate pumps on high-level heads failing or blocking, causing ceiling leaks
• Filters neglected on heads in hard-to-reach ceiling positions
• Outdoor unit coil fouled, degrading performance across every zone at once
• Zone complaints misdiagnosed as control faults when the cause is airflow

Maintenance that prevents them

• Schedule head cleaning on a rolling programme rather than all at once
• Prioritise heads in kitchens, gyms and high-occupancy rooms
• Verify condensate pump operation on ceiling-mounted heads
• Clean the outdoor unit coil annually

Operating in Montreal & Quebec

Hotels and offices in Montreal frequently run VRF with heads in every room, making per-head cleaning economics very favourable on a single visit. Because Quebec buildings run these systems in heating mode for roughly half the year, the indoor heads never get a dormant season in which fouling stops accumulating. Buildings that only schedule cleaning before the cooling season therefore arrive at winter with heads that have already been loading dust since the previous spring.
