First time here
You have reached Hitech Refrigeration Services.
Annual Maintenance Contracts (AMC) is one line of work we run in-house. HRS scopes, installs, and services HVAC, refrigeration, and cold-chain systems across Kerala, with the same company answering for the design, the installation, and the service call afterwards.

The Real Cost of Reactive Service
Reactive service looks cheaper until the site starts failing at the wrong time. An AMC reduces volatility and replaces random repair decision-making with scheduled maintenance.
Without AMC
Unpredictable Costs
Emergency call-out fees and parts replaced at spot prices.
Business Disruption
Waiting days for a technician while customers or staff suffer in the heat.
Shorter Equipment Life
Clogged filters and dirty coils force compressors to overwork and fail early.
With HRS AMC
Fixed Annual Budget
No emergency approval chains. Costs are known and structured.
Priority Response
AMC clients jump the queue. You get SLA-driven response times during peak summer.
Preventive Discipline
4 planned seasonal tune-ups to clean coils, check gas, and catch failing parts before they stop the system.
The Three AMC Tiers
We structure contracts based on site reality, not just unit count. Choose the protection level that fits your operational risk.
Type 2: Standard
The balanced sweet spot. Covers routine spares that fail most often, keeping costs predictable.
Best for: Offices, retail, residential complexes, mid-life equipment.
- All preventive maintenance visits
- Priority emergency response
- Routine spares (PCBs, motors, sensors)
- Discounted labour on major faults
- Compressor billed separately
Type 1: Comprehensive
Highest protection model. Covers all parts including the compressor. Zero surprise repair bills.
Best for: Server rooms, hospitals, hospitality, high-dependence sites.
- All preventive maintenance visits
- Priority emergency response
- Routine spares (PCBs, motors, etc.)
- Major components (Compressors)
- Zero additional repair billing
Type 2: Standard
The balanced sweet spot. Covers routine spares that fail most often, keeping costs predictable.
Best for: Offices, retail, residential complexes, mid-life equipment.
- All preventive maintenance visits
- Priority emergency response
- Routine spares (PCBs, motors, sensors)
- Discounted labour on major faults
- Compressor billed separately
Type 3: Labour Only
Structured maintenance discipline without the premium of parts coverage.
Best for: New equipment under OEM warranty, budget-sensitive sites.
- All preventive maintenance visits
- Priority emergency response
- Inspection & diagnostic labour
- All parts billed separately
- Cost-effective compliance

How This Work Runs on Site
How the job runs
- •We review equipment type, age, criticality, and failure exposure before recommending the right AMC tier.
- •Contract scope, visit frequency, response expectations, and exclusions are clarified before onboarding.
- •Preventive visits, breakdown calls, and service reporting then run to the agreed contract structure.
What is in scope
- •Defined AMC tiers with clear differences between comprehensive, standard, and labour-only cover
- •Scheduled preventive maintenance, breakdown response, and reporting cadence
- •Inspection or upgrade recommendations for voltage stabilisers, AC stands, catwalk access, and outdoor-unit cages where poor access or exposure creates repeat risk
- •Indoor air purification treatment, testing and air balancing, AHU, FCU, and chiller checks where included in the contract scope
- •Commercial support options for SLA-led response expectations and multi-site accounts
What stands behind it
- •AMC value is built around predictable maintenance, faster response, and reduced downtime rather than vague yearly servicing promises.
- •Scope clarity helps buyers understand exactly what is and is not covered before contract sign-off.
- •HRS supports both residential and commercial accounts with structured service continuity across Kerala.
Frequently Asked Questions
What is the difference between the three AMC tiers?
Type 1 Comprehensive covers all parts including the compressor, so repairs do not create additional billing shocks. Type 2 Standard covers routine spares such as boards, capacitors, motors, and sensors, but compressor replacement is separate. Type 3 Labour Only covers service visits and labour while parts are billed separately. Type 2 is usually the best fit for many offices, retail sites, and residential complexes.
How many service visits are included in an AMC?
Our standard AMC includes two planned preventive maintenance (PPM) visits a year across all three tiers, which is what comfort AC in Kerala conditions actually needs: one before the summer load arrives and one before the monsoon, when drainage and coil hygiene matter most. Higher-dependence commercial, precision and process cooling accounts can opt for a tighter PPM frequency based on occupancy pattern, equipment load, and criticality.
Is round-the-clock emergency breakdown support included?
Yes. All AMC structures include emergency breakdown support and priority over non-contract service calls. Response expectations can be further tightened under SLA-driven corporate agreements where uptime risk is commercially significant.
See how express upgrades work on a service ticket →Does the AMC cover all AC brands?
Yes. We maintain mixed-brand sites across Kerala, including Carrier, Daikin, LG, Midea, Toshiba, Voltas, Hitachi, Godrej, and others. The contract is built around the equipment mix on site, not around a single brand.
Do AMC plans cover chillers, AHUs, and FCUs?
Yes, commercial AMC scopes can include air-cooled chillers, water-cooled chillers, AHUs, FCUs, chilled-water piping checks, filters, coils, controls, valves, and related preventive maintenance. The final scope depends on the equipment list and site criticality.
Are reefer trucks and bus AC systems covered under these AMC plans?
No. Transport cooling systems (TRUs and bus AC) are subject to high operational variability that makes fixed-rate AMC structures unviable. For the transport sector, we provide structured periodic maintenance and scheduled servicing instead of annual contracts.
Will an AMC review stabilisers, stands, cages, and service access?
Yes. During AMC onboarding or preventive visits, we can flag weak voltage protection, unsafe AC stands, missing catwalk access for multiple outdoor units, or outdoor-unit cages needed in public-facing areas. These are quoted as add-on upgrades when required.
