From 10+ years of field experience, Kara Aqua shares what a proper RO Annual Maintenance Contract should cover, what it should cost and how to choose a reliable maintenance partner in Delhi.
Get RO AMC Service
RO AMC (Annual Maintenance Contract) is a yearly service agreement where a certified technician visits your home or office on a fixed schedule to service the RO purifier, change filters, check the membrane, test TDS output and identify minor issues before they become expensive failures — reducing the need for emergency RO repair down the line.
Delhi's water quality is not uniform. The PDF guide notes TDS levels ranging from around 300 to over 1,200 ppm depending on locality. Laxmi Nagar and parts of East Delhi can see 900–1100 ppm from borewell-fed lines, while some Noida municipal-supply sectors are closer to 350–450 ppm. Higher TDS can mean faster membrane fouling, quicker filter clogging and greater pump strain — which is also why correct RO installation matched to your local water source matters from day one.
A genuine, comprehensive RO AMC service in Delhi should involve regular preventive visits rather than a single annual filter change.
Typically 3–4 visits a year, around once every three months, so developing faults can be identified early.
Sediment, pre-carbon, post-carbon and RO membrane replacement according to actual system condition. Membranes commonly need replacement every 12–18 months and sooner in high-TDS areas.
Input and output TDS should be checked at every visit. Output creeping above 80–100 ppm can indicate that filters or the membrane need attention.
Pump and motor inspection is especially important in areas where voltage fluctuations can put additional strain on the system.
Small leaks and loose fittings can waste water and damage cabinets, walls and flooring over time.
Good AMC plans provide unlimited or discounted breakdown calls so you are not paying separately every time an issue appears between scheduled visits.

Transparent pricing makes it easier to compare AMC plans. The guide gives the following approximate Delhi NCR ranges.
Filter changes, service visits and labour. Kara Aqua's RO AMC service in Delhi starts from ₹1,999.
Filters, membrane, parts and unlimited visits according to the selected plan.
Custom plans for restaurants, schools and offices are quoted according to plant capacity.
Ask how many visits are included and whether the membrane is covered. Very low-cost plans may exclude important components.
Price alone should not decide your AMC. The field guide recommends checking service capability, transparency and response support.
Prefer a provider genuinely operating in your area so technicians can reach you promptly.
Ask for genuine spare-parts guarantees, especially for membranes used in high-TDS water.
Providers handling both residential and commercial RO systems generally have broader technical experience.
Confirm that doorstep service is standard and not an unexpected extra visit charge.
This is the practical process followed during a doorstep AMC visit.
Input and output TDS are tested, noted and shown to you.
Leaks, loose fittings and cabinet moisture are checked.
Filters and membrane are assessed and replaced only when genuinely due.
Unusual noise and pressure are checked to identify pump or motor concerns.
The system is tested again after maintenance; the guide generally targets under 50–80 ppm depending on source water.
A simple record explains what was done and what to watch for before the next visit.
Restaurants, schools and offices have higher usage and greater dependence on continuous purified water, so their AMC needs can differ from a home plan.
High-usage sites may need monthly filter checks rather than quarterly checks.
A backup unit can help operations continue while servicing is being carried out.
Faster breakdown response matters when downtime affects many people.
A 50-student school canteen and a 500-cover restaurant do not have the same maintenance requirements.
The guide specifically discusses service experience across Laxmi Nagar, Preet Vihar, East Delhi and Noida.
Common questions answered directly from the RO AMC Service guide.
After 10+ years of hands-on RO servicing in Delhi, the guide's key lesson is simple: many sudden failures are slow problems that a proper AMC visit could catch earlier. If your RO has not been serviced in the last 3–4 months, consider a transparent AMC plan.
