Our AMC (Annual Maintenance Contract) gives you guaranteed 24-hour on-site emergency response across all Tamil Nadu districts — 7 days a week, 365 days a year. It also gives you 4 scheduled preventive maintenance visits per year, timed to prepare your cold room for peak load seasons. Before summer begins, our engineer cleans the condenser coils, checks refrigerant levels, verifies compressor current draw against specification, and inspects door seals — the maintenance actions that prevent the summer breakdown before it happens. Before the monsoon, we check electrical connections and drainage. These scheduled visits are what separate cold rooms that run reliably for 15 to 20 years from cold rooms that require expensive emergency repairs every 18 months.

Our AMC covers all brands and makes of cold rooms in Tamil Nadu — not just cold rooms we installed. If you have a cold room from another manufacturer or installer and you are not satisfied with the after-sales support you are receiving, we can take over maintenance responsibility. We first conduct an assessment visit to understand the current condition of the system, then provide an AMC quotation that reflects the actual maintenance commitment required. Multi-location AMC packages are available for businesses with cold rooms across multiple Tamil Nadu districts — with consolidated reporting and a single point of contact for all service coordination.

Cold rooms do not fail on schedule. They fail on Friday evenings before Saturday banquets. They fail on the first day of peak summer when the compressor, already running hard, encounters a condenser coil clogged with dust from an entire year of Tamil Nadu’s industrial air. They fail on Sunday nights when the warehouse is locked and nobody notices the temperature alarm until Monday morning — by which time the product inside has been exposed to a dangerous temperature range for 12 hours. The question is not whether your cold room will need emergency service at an inconvenient time. The question is whether you have a service agreement that guarantees a response within 24 hours, or whether you will spend hours calling different service providers and hoping one can come.

Frequently Asked Questions

AMC stands for Annual Maintenance Contract. A cold room AMC is a service agreement between you and The Green Box under which we commit to 4 scheduled preventive maintenance visits per year and guaranteed emergency breakdown response within 24 hours anywhere in Tamil Nadu. Each scheduled visit covers: compressor check (oil level, current draw, suction and discharge pressure), condenser coil cleaning, evaporator coil inspection and cleaning, refrigerant level check, door seal and hinge inspection, temperature controller calibration check, defrost cycle verification, and a written maintenance report. AMC clients are prioritised over non-contract clients for emergency response.

AMC clients receive guaranteed 24-hour on-site response for cold room breakdowns anywhere in Tamil Nadu — 7 days a week, including Sundays and public holidays. For Coimbatore clients, typical response is under 4 hours. For Chennai, Madurai, Salem, Trichy, and other major districts, typical response is 8 to 16 hours. We maintain a service engineer network across Tamil Nadu to ensure this response time is achievable regardless of location.

AMC pricing depends on the cold room size, temperature range, number of refrigeration units, and your location. A single compressor walk-in cold room AMC starts from approximately ₹12,000 to ₹18,000 per year. Multi-compressor cold rooms or cold storage with multiple chambers are priced higher. We provide an AMC quotation during or after the site visit — or separately for existing cold rooms not installed by us. All AMC prices include 4 scheduled visits and 24-hour breakdown response. Spare parts consumed during emergency repairs are charged at cost.

Yes. We provide AMC for all brands and makes of cold rooms in Tamil Nadu — Daikin, Blue Star, Carrier, Haier, locally installed systems, and any other brand or make. Our service engineers are trained on all major refrigeration systems. For a new AMC on an existing cold room, we first conduct an assessment visit to inspect the current condition of the system and identify any pre-existing issues before committing to a service agreement. This ensures the AMC we provide matches the actual condition of your cold room.

If a spare part failure is identified during a scheduled AMC visit, we inform you immediately and provide a parts quotation. For common parts we carry on our service vehicles (capacitors, contactors, expansion valves, door seals, hinges), we replace them the same day. For less common parts (compressors, PCBs, specific valves), we procure and replace within 2 to 5 working days depending on part availability. Emergency breakdown repair parts are also available at cost on top of AMC pricing — this is disclosed clearly in the AMC agreement before you sign.

Our standard AMC includes 4 scheduled preventive maintenance visits per year — one per quarter. We schedule these visits with you in advance so they align with your operational pattern (before peak summer load, before monsoon, etc.). Additional visits beyond the 4 scheduled ones can be arranged at a day-visit charge. We do not count emergency breakdown calls as scheduled visits — breakdown response is provided separately and does not use your scheduled visit allocation.

A standard preventive maintenance visit includes: compressor motor current draw measurement, suction and discharge pressure check, compressor oil level inspection, condenser coil cleaning with compressed air and chemical flush (annually), evaporator coil inspection and fin straightening, refrigerant level check and top-up if required (refrigerant charged at cost), door seal condition inspection and replacement if worn, cam-lift hinge operation check, temperature controller accuracy check against calibrated thermometer, defrost cycle timing verification, electrical connection tightness check, and a written maintenance report for your records.

Yes. Multi-location AMC packages are available for businesses with cold rooms across multiple Tamil Nadu districts — pharmaceutical distribution networks, hotel chains, food processing companies with multiple plants, and retail chains. Multi-location AMC is priced per cold room with a volume discount for 3 or more units. We provide a consolidated quarterly maintenance report across all locations and a single point of contact for all service coordination.

Refrigerant is typically charged at cost under AMC — it is not included in the fixed AMC price. This is standard industry practice because refrigerant consumption varies significantly between cold rooms depending on their condition, door cycle frequency, and ambient temperature. A well-maintained cold room with no leaks typically requires zero or minimal refrigerant top-up per year. A room with a slow leak may require top-up every 6 months. We identify and repair refrigerant leaks during maintenance visits — which reduces ongoing refrigerant cost for AMC clients compared to non-AMC cold rooms that go longer between service visits.

Our AMC service covers all Tamil Nadu districts. Coimbatore, Chennai, Madurai, Salem, Trichy, Tiruppur, Erode, Dindigul, Tirunelveli, Hosur, Karur, Namakkal, Vellore, Thoothukudi, Nagapattinam, Thanjavur, Ariyalur, Perambalur, Pudukottai, and all other locations. We maintain a service engineer network across Tamil Nadu to ensure 24-hour emergency response is achievable across the state. Call +91 9392180074 to get an AMC quotation for your location.
