The Right Repair Route
A service ticket works better when the fault is routed correctly from the start.
An in-warranty unit is normal work for us. On the brands HRS is authorised for, we log the claim through the official channel; on the rest, we diagnose the fault and keep your cover intact. Either way the spares that go in are genuine. Once the warranty ends, the same call gets you a convenient appointment and the right technician without a long brand-service workflow.
Repair versus warranty
The ticket is separated into chargeable, manufacturer-claim, AMC, or express support before the visit.
Fault urgency
Critical spaces move differently from normal home and office service calls.
Parts path
Genuine manufacturer parts only, on every brand we service, whether or not HRS is appointed for it.
Clear handover
Diagnosis, repair path, exclusions, and next steps are documented after the visit.
Service Routes
Choose the service route that matches the fault and urgency.
One-off repairs, warranty support, express response, and shifting work all need different information at booking.
Chargeable Repair
Best for: Homes, offices, and commercial sites that want a convenient appointment without a long manufacturer process.
HRS focus: One-call booking and, for standard requests, a visit within the week. Cooling faults, leaks, drainage, gas correction, PCBs, motors, compressors, and controls.
In-Warranty Support
Best for: Units still inside the warranty window, whether HRS sold them or another retailer did.
HRS focus: Brand-recognised diagnosis, genuine parts on every brand, claims logged directly on the brands we are authorised for, and clear claim routing on the rest.
Express Support
Best for: Hospitals, theatres, server rooms, cold rooms, restaurants, and urgent sites.
HRS focus: Priority routing by site criticality, equipment type, location, and likely specialist need.
Accessory Repair and Upgrades
Best for: Sites needing safer mounting, power protection, or outdoor-unit protection during service or relocation.
HRS focus: Voltage stabilisers, wall-mounted AC stands, AC floor stands, and cages for public-facing outdoor units.
Retrofitting and AC Shifting
Best for: Renovations, old-unit replacement, relocation, and route corrections.
HRS focus: Recovery, rerouting, recommissioning, drainage, electrical checks, and practical handover.

How This Work Runs on Site
How the job runs
- •We first separate the ticket type: chargeable repair, HRS-sold warranty support, AMC breakdown, or express emergency.
- •Urgent calls are triaged by site criticality, equipment type, fault symptom, location, and likely specialist requirement before routing.
- •The technician documents the diagnosis, repair path, warranty status, parts requirement, and next step so the client is not left guessing.
What is in scope
- •Chargeable AC and refrigeration repair, breakdown attendance, retrofitting, and AC shifting for the general public across major brands
- •Warranty-aware service for HRS-sold systems and authorised brand workflows where applicable
- •Accessory upgrades such as voltage stabilisers, wall-mounted AC stands, AC floor stands, and cages for public-facing outdoor units
- •Express routing for critical spaces such as theatres, hospitals, server rooms, cold rooms, restaurants, and retail operations
What stands behind it
- •HRS combines routine repair, warranty handling, AMC priority, and emergency escalation under one service route.
- •Authorised relationships with Carrier, Daikin, LG, and Midea support cleaner documentation, genuine parts access, and stronger service continuity.
- •Critical clients benefit from structured triage rather than a generic repair queue when downtime affects operations or safety.
Frequently Asked Questions
Do I need to have used HRS before to book a service call?
No. You do not need to have purchased the unit from HRS or to be on an AMC. We handle one-off repairs across all major AC and refrigeration brands, whether the unit is still inside its warranty period or well past it.
My AC is still under warranty but I did not buy it from HRS. Will you attend?
Yes. An in-warranty unit is normal work for us, not a call we push away. On the brands where HRS is the authorised partner, we log the claim through the official channel so the coverage continues undisturbed. On other brands, we attend, diagnose, and tell you plainly which part of the fault the manufacturer should be carrying and which part is chargeable, so nothing done on our visit puts your coverage at risk.
What is the difference between warranty service and out-of-warranty service?
Warranty service applies when the manufacturer is covering the fault, usually because the unit is still inside its warranty period and the failure is a covered defect. We handle that end-to-end for products HRS has sold and for the brands where we are the authorised partner, and we handle diagnosis and claim routing on in-warranty units from other brands. Out-of-warranty service is regular chargeable repair work, where parts and labour are billed normally.
How many services are included during the warranty period?
Across a standard two-year warranty period on an HRS-sold system, four visits are scheduled: three dry services and one wet service. A dry service covers filters, coil and blower inspection, drain and drain-pan checks, electrical connections and recorded performance readings. The wet service is the deeper visit where the indoor coil is chemically washed with the drain path properly directed. Keeping that schedule protects the coverage as well as the equipment, because neglect-driven failures are the ones a manufacturer is entitled to question.
What does 'express service' mean exactly?
Express is an upgrade on a normal service ticket. If your fault cannot wait for a routine slot, the call gets pushed up the queue and the nearest suitable technician is routed to you on priority. It applies to both warranty and out-of-warranty tickets.
Which brands and product types do you service?
We service major AC and refrigeration brands including Carrier, Daikin, LG, Midea, Voltas, Hitachi, Samsung, Panasonic, Toshiba, and Godrej. HRS is an authorised sales and service partner for Carrier and Daikin, and an authorised dealer for LG, Godrej, Toshiba, and Midea. In-warranty and out-of-warranty repair are both available across all of the above.
If HRS sold me the unit, what does the HRS guarantee add on top of the manufacturer warranty?
Any faults arising within 30 days of a successful repair or service will be corrected at no extra charge, subject to exceptions. Manufacturer warranty remains separate and follows the brand terms.
Is there a charge for site inspection or diagnosis?
No. Site inspection and diagnosis are free. Repair charges depend on part availability and the time and effort involved, and the repair scope is shared before work starts.
When will HRS respond to my request?
HRS provides an appropriate response within two business days. Visit and repair timing are confirmed after reviewing the request; any agreed contract SLA applies.
Are there cancellation charges?
No cancellation charges apply.
Can a service visit include stabilisers, AC stands, or outdoor-unit cages?
Yes. If the site needs safer support or better electrical protection, we can quote voltage stabilisers, wall-mounted AC stands, AC floor stands, or cages for public-facing outdoor units as part of a service, shifting, replacement, or retrofit visit.

Need AC or refrigeration service?
