Multi-Zone Split Systems
One outdoor unit serving many indoor units, each with its own controller. The practical answer for a building with rooms that are used at different times.
Up to 4 indoor units per outdoor- Home
- AC for Commercial
AC for Commercial
Commercial cooling designed around how your building is actually used, installed as one coordinated scope.
Commercial air conditioning is not a bigger version of a home split. A building has more people in it at different times, more glass, more heat gain from the structure, and far more to lose when the system is down.
We design and install the full HVAC scope for office buildings, clinics, retail floors, showrooms, hotels, schools and industrial facilities across Kochi and Ernakulam — load calculation, equipment selection, duct and pipe routing, electrical, controls, commissioning and handover, handled as a single contract so there is no gap between suppliers.
Systems
Commercial systems we install
Each of these suits a different building. The right one depends on layout, occupancy and hours of use.
VRF / VRV
True variable refrigerant flow with a single refrigerant circuit running long distances. Up to 64 connected indoor units with high-level energy efficiency at part load.
Up to 64 indoor unitsCommercial Cassette
Four-way ceiling cassettes with individually controlled vanes. Standard for office floors, retail spaces, restaurants and showrooms.
3.6 - 14 kWDucted Split Systems
High-static ducted units feeding grille outlets in the false ceiling. Suits showrooms, halls and any space where visible units are not acceptable.
5.5 - 22 kWPackaged Units
Floor-standing package units that need no false ceiling work. Common in shops, clinics and workshops where ceiling height is limited.
7.2 - 22 kWAHU & Ventilation
Air handling and ventilation equipment for fresh air intake, filtration and exhaust in commercial and industrial spaces.
Fresh air & exhaust
By sector
Different buildings, different problems
We design around the actual constraints of the sector rather than a standard specification.
Offices & IT
Server rooms and cabins need dedicated cooling with tight temperature control and filtration, not shared comfort cooling.
Retail & Showrooms
Glass-fronted showrooms trap heat and need higher capacity plus considered distribution to avoid hot spots.
Hospitals & Clinics
Temperature and air quality are clinical requirements, so zoning, filtration and redundancy drive the design.
Hotels & Restaurants
Guest room comfort, kitchen heat removal and cold storage all have to work at once during service.
Educational Buildings
Large volumes, long operating hours and a hard budget make part-load efficiency the deciding factor.
Industrial Facilities
Process heat, dust and high ambient temperatures need equipment specified for continuous duty.
For building owners
Running cost is where the money is
An oversized or poorly zoned system spends most of its life at part load, which is exactly where it is least efficient.
Part-load efficiency
Variable capacity systems hold their efficiency far better at low load than a fixed-speed system, which is where most commercial buildings spend much of the year.
Zoning that matches use
Rooms used for two hours a day should not be conditioned on the same schedule as the whole floor. Independent zone control is usually the fastest payback on a commercial upgrade.
Serviceable design
We specify equipment whose components a technician can actually reach, so a fault does not become a day of downtime waiting on a crane or a sealed cassette.
FAQ
Commercial AC questions
Answers to the questions building owners and facility managers ask most.
We calculate heat gain room by room: floor area, orientation, glazing, external wall exposure, ceiling height, occupancy, lighting load and equipment. That produces a load figure per room, which we then map onto indoor unit capacity and air distribution rather than simply dividing the building area by a rule of thumb.
In most cases yes. We will survey the installed equipment, identify the make, capacity and refrigerant, and quote a like-for-like replacement or a properly matched upgrade. If your existing system is already efficient, we will say so rather than sell you a replacement you do not need.
We handle commercial breakdowns for buildings we installed and, where the equipment is within its serviceable life, for systems installed by others. We understand that for a clinic or a retail floor a cooling failure is an operational emergency, so response time matters as much as the repair.
Yes. Indoor distribution board upgrades, control wiring, earth bonding and integration with building management or BMS systems are all within our scope, which means one contractor rather than three.
Yes, and for an occupied building we usually recommend it. Phasing lets each floor be commissioned and occupied before the next begins, so the building keeps running throughout.
