During humid spring conditions or prolonged rain in Guangzhou and the Pearl River Delta, hotel and guesthouse rooms can develop damp windows and stale fabrics. If guests notice mustiness when the air conditioning starts, compare first-entry odors with HVAC-on odors in a vacant room, then share the change with engineering.
Separate Closed-room Staleness from HVAC Odors
If mustiness is present on entry, inspect windows, external wall bases, carpets and curtains. If odors strengthen near supply air after start-up, have engineering check return-air grilles, filters, condensate pans and drain lines. Treat stronger bathroom odors as a separate drain inspection, tracking mustiness and drainage odors independently.
Record Reproducible Conditions by Room Number
- Note the room number, floor and room type, and whether odors are strongest near the bed, window, return-air grille or bathroom.
- Record how long the room was closed, how soon odors appeared after HVAC start-up, and differences between wet and dry weather.
- Compare odor reviews and room-change records. Prioritize rooms with repeated feedback that affects normal availability.
Treat in Batches. Verify Before Handover.
Engineering repairs leaks, standing water and condensate drainage faults while housekeeping addresses damp furnishings. LANGKUI schedules targeted treatment or vacant-room atomization according to odor extent and hotel room availability. Recheck both first-entry and HVAC-on conditions, with room-by-room results for housekeeping.
Frequently Asked Questions
How can hotels in Guangzhou prevent mustiness from returning during humid weather?
Locate moisture sources and address standing water, leaks and drainage faults, then clean and dry affected furnishings. After treatment, add checks following rain and closed-room periods to housekeeping inspections.
What should a Guangzhou hotel prepare for an on-site assessment?
Prepare the address, affected room numbers and quantity, plus observations during HVAC operation, room closure and rain. On-site treatment is organized from at least 5 guestrooms, so housekeeping can group problem rooms by floor or room type.
