Real Experiences
Verified testimonials from home owners, apartment associations, and small businesses.
“Super quick! The RO purifier had a salty taste and the local mechanic said the full unit needs replacement. Called Namma RO — the technician tested the TDS live (it was 540) and just replaced the sediment filter and calibrated the membrane.”
“Subscribed to their Gold AMC for our apartment in Chennai. The technician arrives within an hour when we call, explains every step, and carries genuine spares. The whole building now uses them.”
“Very clean and punctual. They showed the factory-sealed membrane pack with the QR code and left the kitchen sink spotless. Everything they promised was honest. Truly ‘Namma’ service.”
