What do recent reviews say?
Most long-term customers praise Kumar's team for punctual, tidy work and chemical cleaning quality. However, recent reviews flag inconsistent pricing (especially drain services), unresolved aircon cooling problems on second visits, and management delays. The business appears split: strong field technicians but weak pricing transparency and follow-through.
Praised for
- prompt arrival and scheduling
- professional technicians (especially Kumar, Govind, Vasan)
- thorough cleaning and neat tidiness
- long-term reliability (15+ year customer)
- detailed inspection and explanation
Watch-outs
- misleading/made-up pricing on drain work
- inconsistent service quality between visits
- unresolved technical issues
- appointment cancellations and delays
- poor communication from management

Highly rated for honest, detail-focused servicing when technicians like Aung, Lucas, and Jay show up; many repeat customers over years. But recent complaints flag communication gaps, unexpected price hikes mid-service, and inconsistent follow-ups when problems recur.
