Engineered Environmental Control for High-Performance Spaces.
We design, install, and maintain commercial and premium residential HVAC systems across Greater Sydney. Demanding environments require uncompromising technical precision.
This is an example site built with TradesPro. Your HVAC business can have a site like this, live in 48 hours. Your $1,750 credit covers the build, then it's $47/mo.
The Precision Diagnostic Audit
We don't guess. We measure. Our proprietary audit process utilizes advanced diagnostics to baseline your current environmental performance before proposing engineering solutions.
Thermal Imaging Analysis
Infrared scanning of ductwork, insulation, and building envelopes to identify thermal bridging and efficiency loss.
Dynamic Load Calculations
Precise calculation of sensible and latent heat loads based on architectural specs, occupancy, and solar gain.
Air Quality Profiling
Particulate measurement (PM2.5/PM10), VOC sensing, and CO2 monitoring to ensure healthy indoor environments.
Rooftop Plant & Central Systems Engineering
We architect and deploy heavy-duty VRV/VRF systems, large-tonnage chillers, and central air handling units for tier-1 commercial facilities. Our focus is on redundancy, energy efficiency, and BMS integration.

Energy Efficiency Audit
HVAC systems typically consume 40-60% of total building energy. Our forensic efficiency audits identify precise power consumption inefficiencies through data-logging and load profiling.

Smart Zoning & Automation
Achieve granular control over your environment. We engineer multi-zone systems integrated with leading automation platforms to ensure optimal comfort precisely where and when it's needed, eliminating energy waste in unoccupied spaces.
Mobile & Remote Access
Full system visibility and control via secure iOS/Android applications.
BMS Integration
Native connection with Modbus, BACnet, and central building management architectures.
Air Purification Science
Beyond temperature control, we engineer pristine indoor air quality. Our medical-grade filtration and sterilization modules actively neutralize pathogens, VOCs, and micro-particulates.
HEPA Filtration
True HEPA (H13/H14) filters capturing 99.97% of particles down to 0.3 microns.
UV-C Sterilization
In-duct ultraviolet germicidal irradiation (UVGI) to destroy viral DNA and mold spores.
Ionization
Bipolar ionization technology to agglomerate fine dust and neutralize odors.
CO2 Purging
Automated fresh air intake dampers driven by real-time CO2 sensor data.
Acoustic Engineering: Designing for Silence
In premium residential, library, and executive office applications, mechanical noise is unacceptable. We utilize advanced acoustic lining, vibration isolators, and variable speed compressors to achieve NC (Noise Criterion) levels as low as NC-20.
Custom Ductwork Fabrication
Off-the-shelf components often compromise airflow dynamics. We operate an in-house sheet metal fabrication facility to manufacture bespoke ducting, transitions, and plenums optimized for static pressure and laminar flow.
- Galvanized steel and aluminum construction
- Internal acoustic and thermal insulation
- Precision plasma cutting for complex geometries
The 'Apex 100' Quality Checklist

What Clients Say
4.9 from 87 Google reviews. Commercial plant managers and homeowners alike.
"They retrofitted our 4-storey office tower's VRF plant in 6 weeks without a single day of downtime. The energy audit found 31% in savings. Exceptional engineering."
"Our data centre's CRAC units needed precision cooling at 19 degrees. Apex Air hit every SLA in two years of service. The 24/7 fleet is the real deal."
"The acoustic work in our Mosman home is incredible. You cannot hear the outdoor unit at all. Worth every dollar."
