How We Work

HVAC CONTRACTOR
PROCESS

From first site visit to final handover — here's exactly how Aloft delivers every project with precision and accountability.

🔍
01
Site Inspection

Our engineers visit your site to assess the building layout, ceiling height, insulation, occupancy patterns, and existing infrastructure. We document room-by-room dimensions and identify constraints like structural obstacles, utility access, and outdoor unit placement zones.

✓ Floor plan review & room dimensions
✓ Ceiling & void space assessment
✓ Electrical supply verification
✓ Outdoor unit placement survey
✓ Existing ductwork or system check
🧮
02
Heat Load Calculation

We perform a Manual J / ASHRAE-based heat load calculation to determine exactly how much cooling capacity each zone requires. This prevents undersizing (hot spots) and oversizing (humidity issues, high cost).

✓ U-value analysis (walls, glass, roof)
✓ Solar gain & orientation factor
✓ Occupant & equipment heat load
✓ Fresh air infiltration load
✓ TR / kW capacity per zone
Heat Load Formula
Q = U × A × ΔT + (Occupants × 100W) + Equipment Load + Solar Gain
📐
03
System Design & Duct Layout

Based on load calculations, our engineers design the complete system — selecting equipment, sizing ducts using velocity/pressure methods, and laying out the air distribution network for balanced airflow to all zones.

✓ Equipment selection & brand comparison
✓ Duct sizing (Equal Friction Method)
✓ Diffuser & grille placement design
✓ Refrigerant piping layout
✓ AutoCAD / schematic drawings
📋
04
Proposal & BOQ Submission

We prepare a detailed Bill of Quantities and transparent cost proposal — itemising every unit, fitting, duct section, labour, and material. No hidden charges. You know exactly what you're getting before we start.

✓ Itemised Bill of Quantities (BOQ)
✓ Equipment brand options & pricing
✓ Project timeline & milestones
✓ Warranty & AMC terms
🏗️
05
Installation & Fabrication

Our trained crew fabricates sheet metal ductwork on-site, installs units, runs refrigerant piping, electrical wiring, and drainage lines — following the approved design drawings and safety standards throughout.

✓ Sheet metal duct fabrication
✓ Indoor / outdoor unit mounting
✓ Refrigerant pipe brazing & insulation
✓ Electrical & controls wiring
✓ Drainage & condensate lines
🔬
06
Testing & Commissioning

Before handover, every system undergoes rigorous T&C — pressure testing refrigerant lines, measuring airflow at each diffuser, checking temperature differentials, and verifying BMS control sequences.

✓ Nitrogen pressure leak test
✓ Refrigerant charge & superheat check
✓ Airflow balancing at all diffusers
✓ ΔT verification (supply vs return)
✓ BMS/thermostat programming
Commissioning Target
Supply Air: 13–15°C  |  ΔT: 8–12°C  |  Airflow: ±10% of design CFM

LEARN ABOUT
DUCTABLE
MACHINES

Understand the technology behind modern centralised cooling — how ductable systems move air, condition it, and deliver comfort at scale.

AHU Air Handler SUPPLY DUCT DIFF DIFF RETURN → → → CHILLER Centralised Ductable System Schematic
📦
Package System
Package Unit (PAC)

A self-contained ductable unit housing the compressor, condenser, evaporator, and blower in a single cabinet. Ideal for large open spaces like malls, offices, and server rooms.

How it works: Refrigerant is compressed, condensed (releasing heat outside), then expanded and evaporated to absorb heat from indoor air. The fan circulates conditioned air through duct networks.

Air Handling Unit
AHU — Chilled Water

AHUs circulate and condition large volumes of air using chilled water from a central chiller plant. Used in hospitals, hotels, and large commercial complexes.

How it works: Warm return air passes over a chilled water coil, lowering its temperature. The conditioned air is then pushed through ducts to multiple zones simultaneously.

🔁
Variable Refrigerant
VRV / VRF System

Variable Refrigerant Volume systems use a single outdoor unit connected to multiple indoor units. The inverter compressor modulates refrigerant flow for precise zone control.

How it works: Refrigerant pipes carry variable amounts of refrigerant to each indoor unit independently, allowing simultaneous heating and cooling in different zones with up to 60% energy savings.

Inverter driven Simultaneous H&C 60% energy saving Up to 64 units
❄️
Central Plant
Chiller System

Chillers produce chilled water that is pumped to AHUs and fan coil units throughout a building. The backbone of large-scale centralized cooling in malls, hospitals, and towers.

How it works: A refrigeration cycle removes heat from water (chilling it to ~7°C), which is then circulated through insulated pipes. Return water at 12°C goes back for re-chilling.

Process

HOW DUCTABLE
SYSTEMS WORK

From refrigeration cycle to room comfort — here's the step-by-step engineering behind every Aloft installation.

01
Compression — Raising Refrigerant Pressure

The compressor draws in low-pressure refrigerant gas and compresses it to a high-pressure, high-temperature state. This is the energy input stage — the heart of every refrigeration cycle. Inverter-driven compressors modulate speed based on load demand for maximum efficiency.

02
Condensation — Releasing Heat Outside

Hot compressed refrigerant flows to the outdoor condenser unit where fans push ambient air across coils. Heat is expelled to the outside, and refrigerant converts from gas to a high-pressure liquid. This is why outdoor units blow hot air.

03
Expansion — Pressure Drop Creates Cold

Liquid refrigerant passes through an expansion valve (TEV or electronic), which dramatically drops its pressure and temperature — sometimes to -20°C. This phase change from liquid to a cold vapour-liquid mixture is what enables heat absorption indoors.

04
Evaporation — Absorbing Indoor Heat

Cold refrigerant flows through the indoor evaporator coil. The blower fan draws warm room air across this coil — the refrigerant absorbs the heat and evaporates back to gas. Cooled air is then pushed into the duct network to condition the space.

05
Air Distribution — Duct Network Delivery

Conditioned air travels through insulated sheet metal ducts — main trunks, branch ducts, and finally through diffusers and grilles into each room. Return air grilles collect spent air back to the AHU/package unit to be re-conditioned, completing the cycle.

06
BMS Control — Smart Automation

A Building Management System monitors thermostats, CO₂ sensors, occupancy sensors, and time schedules to automatically adjust cooling output. Energy consumption is optimised by running equipment only at required capacity — reducing electricity bills by 30–50%.
