Commercial HVAC Projects
Commercial AC & Corporate HVAC Systems
Commercial HVAC on an SITC basis across Kerala: design, high-efficiency retrofits, chilled-water and refrigerant piping, clean-room support (ISO 14644-1 Class 5-9), testing, commissioning, and long-term service.
Load-first design
Commercial fit-out coordination
Post-handover service

First time here
You have reached Hitech Refrigeration Services.
Commercial AC & Corporate HVAC Systems 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.
Operating since 1999
Service lineage from Aircon India South, incorporated as Hitech Refrigeration Services Pvt. Ltd. in 2008.
Kerala-wide, from five bases
Head office in Pachalam, Kochi, a dedicated Bus and Reefer facility in Kalamassery, and branch support in Thiruvananthapuram, Kozhikode, and Thiruvalla.

The Commercial Difference
Commercial HVAC is a facility decision, not a tonnage shortcut.
A system can look acceptable on a quotation and still become expensive if the load, air distribution, service access, or fit-out coordination is weak. HRS treats the project as an operating asset from the first site review.
Load and zoning
Sizing accounts for occupancy, glass exposure, equipment heat, operating hours, and how each zone is actually used.
Interior coordination
Piping, drains, ducts, returns, grilles, and access points are coordinated before ceilings and finishes close.
Business continuity
Execution is planned around phased areas, shutdown windows, and live-site constraints where the facility cannot simply stop.
Serviceability
Outdoor units, AHUs, FCUs, dampers, and controls remain reachable after handover, with stands, catwalk access, or protective cages planned where the site needs them.
Scope Paths
The commercial requirement decides the service path.
Some buyers need a new office installation. Others need a careful retrofit, chiller-side support, or fit-out-linked air distribution. We quote each job after seeing the site, because each scope depends on it.
New Commercial Installations
Best for: Offices, banks, retail, hospitality, healthcare, and institutional spaces.
HRS focus: System selection, load logic, zoning, controls, commissioning, and handover.
Retrofit and Replacement
Best for: Existing sites where older units, routes, or layouts are no longer working.
HRS focus: AC replacement, shifting, route correction, refrigerant handling, and recommissioning.
Piping, AHU, FCU and Chiller Support
Best for: Larger facilities with chilled-water, refrigerant piping, or plant-room scope.
HRS focus: Access, insulation, leak testing, controls alignment, and long-term maintenance practicality.
Outdoor Unit Access and Protection
Best for: Public-facing condensers, tight terraces, wall-mounted units, and multiple outdoor-unit banks.
HRS focus: Wall-mounted AC stands, AC floor stands, catwalk stands for multiple outdoor units, protective cages, and voltage stabilisers where needed.
Fit-Out and Controlled Spaces
Best for: Clean rooms, server-adjacent rooms, healthcare, labs, and interior-linked projects.
HRS focus: Air distribution, ventilation, acoustic detailing, and coordination with ceilings and trades.

How This Work Runs on Site
How the job runs
- •We review usage profile, occupancy density, operating hours, and site layout before recommending equipment or system approach.
- •Load calculations, zoning logic, equipment selection, and installation planning are aligned before execution starts.
- •Project delivery proceeds with supervision, commissioning, and handover documentation for the client or facilities team.
What is in scope
- •System recommendation, equipment sizing logic, and commercial project execution planning
- •Installation, retrofitting, AC shifting, chilled-water and refrigerant piping, ducting coordination, ductable throw-count planning, controls alignment, and commissioning support
- •Outdoor-unit access and protection add-ons including wall-mounted AC stands, AC floor stands, catwalk stands for multiple outdoor units, protective cages, and voltage stabilisers
- •AHU, FCU, air-cooled chiller, and water-cooled chiller support where the facility scope requires it
- •AMC and after-sales support structure for ongoing uptime after handover
What stands behind it
- •HRS supports offices, banks, hotels, hospitals, and multi-site commercial buyers across Kerala.
- •Commercial work is handled with engineering accountability, phased execution, and after-sales continuity rather than one-time supply alone.
- •Authorised brand capability and statewide service support strengthen long-term operating reliability.
Frequently Asked Questions
How is commercial HVAC different from residential installation?
Commercial HVAC has longer operating hours, higher occupant load, more zoning requirements, and tighter expectations around controls, ventilation, compliance, and downtime. It needs proper engineering, not residential rule-of-thumb sizing.
Who carries out the site evaluation?
An HRS HVAC engineer, not a sales visit. The same engineering team that surveys the building, runs the load calculation, and checks access and services also sizes and plans the system, so nothing is lost between the quote and the design. Our engineers and technicians are trained by the manufacturers we represent, and HRS works to an ISO 9001:2015 quality system.
Can HRS handle multi-floor and phased commercial projects?
Yes. We support projects that need design coordination, staged execution, site supervision, testing and commissioning, and a handover process that works for live commercial environments. On multi-floor work the SITC scope is usually split by phase so each area is commissioned and handed over before the next one opens up.
How do you reduce disruption during installation?
Commercial projects are usually planned around business continuity. That can mean phased areas, after-hours work, shutdown windows, or tighter coordination with interiors, electrical, civil, and facility teams.
Do you provide post-installation maintenance for commercial accounts?
Yes. For many commercial sites, maintenance discipline is what protects the investment. We support post-handover servicing and AMC arrangements when you need uptime, predictable response, and cleaner long-term asset performance.
See our AMC packages →Can the system report energy use per tenant or per zone?
On current VRF and centrally controlled platforms, yes. Energy distribution reporting attributes consumption to each indoor unit rather than only to the outdoor bank, which supports tenant billing across a shared floor plate without installing a separate electrical sub-meter for every unit. The same controller layer carries BACnet IP and Modbus TCP/IP integration into an existing building management system. Both are far cheaper to specify at design stage than to retrofit after handover.
Can outdoor-unit stands, catwalks, cages, and stabilisers be included?
Yes. Commercial scopes can include wall-mounted AC stands, AC floor stands, catwalk stands for multiple outdoor units, protective cages for public-facing outdoor units, and voltage stabilisers where access, safety, or power quality requires them.
