"My Kent RO stopped working and they fixed it the same evening. Genuine parts, fair price and very polite technician."
"Took the Complete Care AMC — filters changed on schedule and no repair bills all year. Totally worth it."
"Installed a new purifier and explained the right TDS setting for our area's water. Honest, knowledgeable service."
A standard service visit starts around ₹299, filter changes from ₹899 and full servicing with membrane from ₹1,499 depending on your purifier. We always quote the exact charge before starting any work, so there are no surprises on the bill.
For most homes, yes. An AMC covers scheduled services, timely filter/membrane changes and breakdown visits for one fixed annual fee — usually cheaper than paying per repair, and it keeps your water consistently pure. Our Complete Care plan is the most popular for families.
We service and repair all major brands — Kent, Aquaguard, Pureit, Livpure, Blue Star, AO Smith, Havells and others. Our technicians carry common filters and membranes, so most repairs and replacements are completed in a single doorstep visit.
Ideally every 3–4 months, and filters/membrane should be replaced every 6–12 months depending on your water's TDS and usage. In Lucknow's hard-water areas, timely servicing is especially important to keep water safe and your purifier efficient.
Call, WhatsApp or book online — we'll schedule a same-day doorstep visit wherever possible.
