The HRS AMC Lifecycle: What Happens During Your 365-Day Service Contract

Most clients sign an Annual Maintenance Contract and expect a phone call every three months. The reality of a well-structured AMC is considerably more involved - and considerably more valuable. Here is exactly what happens during an HRS AMC from signature to renewal.

Stage 1 - System Assessment: Performance Baseline

Before the contract begins, HRS engineers conduct a full site survey of every unit covered. This is not a visual inspection. It is a documented technical baseline:

• Refrigerant pressures at operating conditions
• Current draw on compressors and fans
• Supply and return air temperatures
• Outdoor unit condenser coil condition
• Filter pressure drop
• Electrical connection integrity
• Control board and thermostat calibration

This baseline becomes the reference against which every future visit is measured. Deterioration is caught by trend analysis, not by waiting for failure.

Stage 2 - Initial Audit: Comprehensive Site Review

Within the first 30 days, a senior engineer conducts an audit that goes beyond the installed equipment. This includes:

• Identifying units running above rated capacity for the space
• Flagging electrical supply issues that could stress equipment
• Documenting access constraints that will affect service scheduling
• Recording any existing defects that pre-date the contract
• Setting up the client's asset register in our service management system

The audit report is shared with the client. Any pre-existing issues are noted to avoid disputes later.

Stage 3 - Preventive Maintenance Schedule: Planned Upkeep

Based on the system assessment and audit, a customised maintenance calendar is built. This is not a generic quarterly schedule - it accounts for:

• Equipment age and historical failure modes
• Usage intensity (24/7 operations versus business-hours-only)
• Environmental conditions (coastal humidity, industrial dust)
• Manufacturer-specified service intervals for each brand and model
• Client operational constraints (no-access periods, peak seasons)

Each scheduled visit has a specific task list for every unit. Engineers arrive with the right tools and parts for that visit, not a generic toolkit.

Stage 4 - Quarterly Service: 4× Per Year

Four times a year, technicians execute the preventive maintenance task list for each covered unit:

Condenser and evaporator coil cleaning - fouled coils are the single largest driver of reduced cooling capacity and increased energy consumption. In Kerala's climate, coils accumulate bio-film, dust, and salt deposits faster than in dry climates.

Refrigerant pressure check - slow refrigerant leaks are common and invisible without instruments. A unit running low on refrigerant works harder, cools less, and eventually fails the compressor.

Electrical checks - contact resistance, capacitor health, relay condition. Electrical failures cause 30–40% of all AC breakdowns.

Filter service - cleaned or replaced per schedule. Blocked filters reduce airflow, causing coil icing and compressor overheating.

Drainage check - blocked condensate drains cause water leaks and biological growth in drain pans.

Stage 5 - Performance Monitoring: 24/7 Oversight

Between visits, HRS monitors critical systems through client-reported data and, for premium AMC clients, remote monitoring integrations. Clients are encouraged to report any change in performance immediately rather than waiting for the next scheduled visit.

Our service management system tracks:

• Call history and recurring issues per unit
• Parts replaced and remaining estimated life
• Performance trend versus the initial baseline

A unit showing a steady drop in cooling output over four quarters is flagged for proactive intervention - before the compressor fails.

Stage 6 - Emergency Response: 4-Hour Average Response Time

AMC clients receive priority dispatch. When a covered unit fails, the response target is:

• Acknowledgement: within 30 minutes of the service call
• On-site arrival: within 4 hours for most Kerala locations
• Critical facilities (data centres, hospitals, cold chain): 2-hour SLA available under premium AMC

Emergency calls are covered under the AMC - no separate callout charge, no parts surcharge for covered components.

Stage 7 - Annual Review: SLA Compliance Report

At the end of each contract year, HRS provides a written annual review covering:

• All visits completed versus scheduled
• All emergency calls responded to and resolution times
• Parts replaced and their cost (transparent, even if absorbed under the AMC)
• Current equipment condition versus baseline from Stage 1
• Recommendations for the coming year - equipment nearing end-of-life, efficiency improvements, capacity changes

This document is your audit trail for facilities management, insurance, and ISO compliance requirements.

Stage 8 - Contract Renewal: Seamless Continuation

AMC renewal is initiated 60 days before expiry. The renewal proposal is based on actual equipment condition from the annual review - not a generic price increase. Where equipment has deteriorated or usage patterns have changed, the coverage terms are adjusted accordingly.

Clients with three or more years of continuous AMC coverage typically see lower renewal costs per unit because their equipment is better maintained and generating fewer emergency calls.
