What an AC AMC Should Cost Per Unit in Kalyan and Thane

An AMC is priced on three things: how many visits a year, how many units, and how much of the failure risk the contractor accepts. Most quotes you receive will be comparable on the first two and wildly different on the third, which is where the arguments come from.

The per-unit ranges that hold up

These are mid-market rates for the Kalyan–Dombivli–Thane belt in 2026. A quote 40% below the bottom of a range is usually preventive-only in disguise, or excludes the two visits that matter — pre-summer and post-monsoon.

What actually changes the price

Four variables move the number more than anything in the sales conversation.

Unit type. A cassette takes roughly twice as long to service as a wall split, because the filters and coil are above a ceiling and the drain tray has to be reached. Ducted systems take longer again.

Access. An outdoor unit on a rear ledge at the fourth floor costs more to reach than one at ground level with a parking space in front. Scaffolding or rope access is quoted separately, always.

Operating hours. Servicing a shop before opening or an office after hours adds a premium of 10–20%. Many customers prefer to pay it rather than close.

Risk transfer. This is the big one. In a comprehensive contract the contractor pays for parts and labour on failures. A compressor replacement at ₹6,499 on an eight-unit site, once, wipes out the margin on the whole contract. That risk is priced in.

The clauses that decide whether it was worth it

Ask for these five, in writing, before signing anything.

• Visit count per unit, per year — not "as required". A contract with no number is a contract with no obligation.
• Response time for a breakdown, in hours, with a stated consequence if missed. Four working hours in summer is a reasonable commercial figure.
• Parts included and excluded, named. Compressor, PCB and fan motor are the three that matter.
• Consumables — gas, copper, drain pipe, insulation. A contract that excludes gas is not comprehensive, however it is labelled.
• How added units are handled mid-term, and at what rate. Fleets grow.

A contract missing the first two is a discount voucher, not maintenance.

Why four visits costs less than two faults

Consider eight cassettes in a Thane office, four years old. Two visits a year at ₹2,300 each is ₹18,400 a year. A compressor failure in June costs ₹6,499 plus a day of discomfort and a rush call-out premium.

One such failure in three years makes the four-visit comprehensive contract the cheaper option, and that is before counting the disruption. The arithmetic only fails if the equipment is new enough that nothing breaks — which is exactly when a preventive-only contract is the sensible buy.

The honest recommendation by fleet age

Under three years: preventive only, two visits, with a defined response time for breakdowns billed at a fixed rate. You are buying scheduling discipline, not risk transfer.

Three to seven years: comprehensive is usually right. Failure probability is rising and the flat fee makes budgeting easy.

Over seven years: get a condition report before renewing. At some point the honest advice is to replace two units rather than insure four, and a contractor with a replacement incentive will not tell you that.
