Why call DrainFix HK for Hung Hom ac condensate drain unblock
- Hung Hom-specific knowledge. Hung Hom is Kowloon harbourfront — Whampoa Garden + Laguna Verde dominate residential. Modern construction means most blocks are simple resident-caused (hair/grease/foreign objects). Older Bulkeley Street / Wuhu Street walk-ups have legacy clay-pipe issues.
- Service-specific method. AC dripping water inside / from outdoor unit = clogged condensate drain in 95% of cases. Blockage is dust + algae build-up at the narrow flexible drain pipe. 10-15 min job. Most-undercharged HK service.
- Fixed price quoted on phone. No 'we'll see when we get there' surprises. From HKD 250.
- 7-day re-block guarantee. Same drain re-blocks within 7 days, we return free.
- Receipt + tax invoice always. For tenant-landlord reimbursement or building AP.
