Why call DrainFix HK for Yuen Long ac condensate drain unblock
- Yuen Long-specific knowledge. Yuen Long is fast-growing NT residential — Yoho Town, Park Yoho, Grand Yoho all newer (2010s+). But many calls come from older Yuen Long Town Centre (Castle Peak Road / Tai Tong Road) and from village houses (鄉村屋) in surrounding hamlets. Village house plumbing is unique to NT.
- 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.
