AC & Refrigeration Service: Warranty, Repair & Express Support

In brief: HRS handles AC and refrigeration service, breakdown repairs, retrofitting, and AC shifting across Kerala on a chargeable basis for the general public, which is the bulk of our service work. Separately, we provide full manufacturer warranty support for the systems HRS sells, backed by our own installation and service guarantee. Any service ticket, warranty or out-of-warranty, can be upgraded to express response when the fault cannot wait.

Most of the service calls we receive every week are not warranty cases. They are normal, chargeable repair jobs from homes, offices, and commercial sites where a unit has stopped cooling well, started leaking, become noisy, or simply not been touched in a while. That is the day-to-day work our service network is built around.

Warranty service sits alongside that as a more specific category, mainly for systems we have sold and installed, where HRS places its own guarantee on top of the manufacturer's coverage.

Best For: Homeowners, businesses, and facility managers who need trustworthy AC or refrigeration repair on a chargeable basis, plus warranty support for systems HRS installed.

Out-of-Warranty Service for the General Public

This is the service most people actually book. Whether or not the unit was bought from HRS, and whether or not it is still under warranty, we will diagnose the fault and quote a clear repair on a chargeable basis.

Typical jobs in this category include:

• AC not cooling, weak airflow, or short-cycling
• Water leakage, drainage issues, blocked drain trays
• Gas top-up, leak testing, and refrigerant correction
• AC replacement, AC shifting, refrigerant recovery or gas discharge handling where relocation requires it
• PCB, sensor, capacitor, fan motor, or compressor replacement
• Inverter board faults and error-code diagnosis
• Chiller, AHU, and FCU breakdown attendance for commercial sites where the scope fits our service team
• Cold-room and refrigeration repair where the system is not under brand cover
• Reefer and bus AC repair outside the original warranty window

We service major brands including Carrier, Daikin, LG, Midea, Voltas, Hitachi, Samsung, Panasonic, Toshiba, and Godrej. Genuine spare parts are used where available, and substitutes are clearly flagged when they are not.

Pricing is shared upfront once the technician has done the on-site diagnosis. There is no bundled subscription you have to commit to in order to book a single repair.

Warranty Service for HRS-Sold Systems

When you buy your AC or refrigeration system from HRS, the warranty side is handled in-house instead of routed through a third party. That matters because the team that installed the unit is the same team responsible for any covered fault that appears during the warranty period.

For HRS-sold systems, warranty service includes:

• Brand-recognised diagnosis using genuine procedures and tools
• Genuine OEM spare parts from the official manufacturer supply chain
• Manufacturer-accepted documentation entered into the service portal where required
• Refrigerant handling and inverter or VRV control diagnostics in line with brand procedure
• A clean, continuous service history on the unit

On top of the brand warranty, HRS places its own installation and service guarantee on the system. The brand warranty covers the product. The HRS guarantee covers everything around it: the install quality, the commissioning, and the service relationship over the equipment's life. If something goes wrong inside the workmanship layer, that is on us, not on you.

Authorised Brand Partnerships

HRS is an authorised sales and service partner for Carrier and Daikin in Kerala, and an authorised service dealer for LG and Midea. For warranty work on these brands, the claim is logged correctly so the unit's warranty status remains intact and auditable.

For other brands, our trained technicians can still carry out service work, but that is handled as out-of-warranty service rather than authorised warranty support.

Express Service: Upgrading a Ticket for Emergencies

Express service is not a separate product. It is an upgrade on a normal service ticket, available on both warranty and out-of-warranty calls, used when the fault cannot wait for a routine slot.

Mission-critical environments we support on express

For some sites, an AC failure is not an inconvenience: it stops trade, halts a procedure, or threatens stock and equipment within hours. Express response is built around exactly these situations:

• Cinemas, theatres, and auditoriums where a screening or event is in progress and the audience is already seated
• Hospitals, clinics, and diagnostic centres with operating theatres, ICUs, MRI rooms, and pharmacy storage that have to stay inside a defined temperature band
• Banks and ATM networks where overheating drives equipment shutdown and customer-facing downtime
• Server rooms, IT closets, and equipment rooms where temperature alarms can trigger asset risk within minutes
• Cold rooms, walk-in chillers, and reefer vehicles where temperature drift turns into stock loss
• QSRs, restaurants, and hospitality floors during peak service hours, where ambient comfort directly affects continued trade
• Retail outlets, showrooms, and supermarkets where extended downtime affects footfall and frozen inventory
• Manufacturing and process areas where ambient or process cooling is tied to production continuity

If the issue sits inside a technical room, cold-chain operation, or larger commercial site, the express ticket may be routed through our precision cooling, cold room, or commercial HVAC team instead of a generic AC repair route.

If you operate any of the above and want a structured response path before something goes wrong, an AMC contract makes that path materially faster.

When any ticket is worth pushing into express

Beyond the mission-critical list, the express upgrade also makes sense whenever:

• cooling has failed completely in an occupied or operating space
• a cold room or reefer unit is drifting outside safe temperature
• an AC system is repeatedly tripping power
• water leakage is threatening stock, ceilings, or electrical points
• a business cannot stay open or functional without fast attention

When you flag a call as urgent, we triage it on the phone, match the right technician or division (residential, commercial, cold-chain, bus AC), and aim to restore operation on the first visit wherever the fault allows. If the fault needs parts or a follow-up intervention, we define the next step clearly instead of leaving you waiting.

Express coverage runs across our service network. If you have an AMC with us, you move through the queue faster because your equipment history, site access notes, and fault history are already on file.

How a Typical Service Call Works

1. Booking and triage. You share the brand, model, location, and a short description of what is going wrong. We confirm whether the call is warranty or chargeable, and whether you want the express upgrade.
2. Technician routing. The nearest suitable technician or specialist division is assigned based on the equipment category and location.
3. On-site diagnosis. The technician identifies whether the fault is electrical, refrigerant-related, airflow-related, control-related, drainage-related, or a larger component issue.
4. Quote and approval. For chargeable work, the cost of parts and labour is shared before any repair is started. For warranty work, the claim path is explained.
5. Repair and restoration. Where possible, the unit is restored on the same visit. Where parts or a deeper repair are needed, we book the follow-up clearly.
6. Handover. You get a summary of what was done, what was replaced, and any preventive notes for the future.

Before You Call

You can speed up diagnosis by keeping a few details ready:

• Brand, model, and serial number
• Approximate purchase or installation date
• Error code or a photo of the symptom (water leak, ice buildup, display code)
• Site address and access details (floor, parking, lift)
• What changed just before the fault appeared

For commercial sites with multiple units, mention whether the issue affects one unit, one zone, or the whole installation. That lets us send the right technician and likely spares on the first visit.

When Warranty Does Not Apply

Even on units inside the warranty window, manufacturers do not cover every reason an AC can stop working. The most common exclusions are:

• Electrical surge or unstable power damage
• Physical damage during shifting, renovation, or water ingress from external causes
• Pest or rodent damage to wiring and insulation
• Prior third-party repair work that breaks the service chain
• Neglect-related failures where basic operating conditions were not maintained

If a unit falls outside warranty for any of these reasons, the call simply moves to chargeable service. We will still diagnose it and give you a clear repair path using genuine parts where available.

After the Repair

A breakdown visit fixes the immediate problem, but recurring failures usually point to something larger: dirty coils, weak refrigerant charge, drainage problems, voltage issues, or simply a unit that has not been properly maintained for a long time.

If the same fault keeps coming back, the smarter next step is usually to move from reactive repair into a structured maintenance plan. Pair regular service with an AMC contract so the system is documented, monitored, and easier to route quickly when issues do appear.
