Services
From a 5,000 sq.ft office fit-out to a 4 lakh sq.ft factory — the same partner signs your drawings, supervises your installation and answers your service calls.

Heat-load calculation, system selection, ducting design, installation and commissioning of chilled-water, VRF and DX systems for commercial and institutional spaces.

Class 10,000 – 1,00,000 cleanrooms, controlled environments and process cooling for pharmaceutical, electronics and food-grade facilities with full validation support.
Audit existing systems, identify energy losses and execute retrofits — variable-speed drives, EC fans, controls upgrades and refrigerant migration with measured payback.
Annual maintenance contracts with planned preventive visits, spares-on-call, and a 24×7 break-down desk. Average response time under four hours across NCR.
Engagement
We protect your timeline by being honest about ours. Most engagements move through four stages — and at every stage, you know the next milestone, the named owner, and the decisions waiting on you.
STAGE 01
Brief
Site walk, requirements, constraints — captured by a senior engineer, not a salesperson.
STAGE 02
Design
Heat loads, single-line diagrams, equipment selection and a transparent BOQ.
STAGE 03
Build
In-house teams execute under a named project manager with weekly photo-reports.
STAGE 04
Run
Commissioning, training, documentation, then a 12-month defect-liability and AMC option.
