Your family comfort and health with energy efficient cooling and heating done right the 1st time in your home

Design & Engineering

Since 1994, we have been developing a client portfolio including developers of large commercial-industrial-residential-retail projects, so you can be assured that our engineers have the right skills to custom-design the right HVAC system. One which will best meet your energy efficiency and temperature environment requirements, and budget.

We design for new construction projects, refurbishments and upgrades:
• Ducted systems
• Multi-head systems
• Multi-split and split systems
• Variable Refrigerant Volume (VRV) systems
This is the first stage of our “Single Source Supplier” offering in which the one team is responsible for design, installation, servicing and preventative maintenance.


No two installations are the same. Having installed complex ducted systems for shopping centres, high-rise office blocks and residential towers as well as industrial facilities, J&J Metro Air Conditioning has the experience to professionally manage and install all HVAC configurations in any type of building.

We have long standing relationships with the world leaders in air conditioning technology (eg. Actron, Daikin, Fujitsu, Hitachi, Samsung and Temperzone) to source the right equipment at competitive prices.

Our engineers and technicians are skilled in new building starts as well as refurbishments which require new equipment to be connected to the existing system.

For compliant and quality assured design and installation for your commercial air conditioning and HVAC needs


Regular servicing is “cheap insurance” for any HVAC system. It ensures workers or residents enjoy consistently comfortable temperatures in your building and the equipment is operating efficiently, thereby extending its life expectancy.

J&J Metro Air Conditioning is familiar with all brands and models of HVAC systems and offers the flexibility of 3, 6 and 12 month service schedules. These are complemented by our Quick Response service crews and Emergency Breakdown call-out teams.

All of our work is covered by a 5 year warranty for complete peace of mind.

Preventative Maintenance

J&J Metro Air Conditioning provides a comprehensive preventative maintenance service which keeps systems running at peak performance, extends the life span of equipment and prevents unnecessary increases in costs. Our service includes:

• Replacement of air filters
• Replacement of drive belts
• Inspection of relays and contactors
• Lubrication of bearings and rotating components
• Checking the refrigerant

Preventive maintenance is essential to the proper functioning of air conditioning and heating equipment. If preventive maintenance is not performed regularly or if it is done haphazardly the equipment will require extensive and costly repairs at a later date and and lose reliability in the process.

Preventive maintenance includes regular inspections each year during which proper operation of the equipment is checked and verified. All mechanical equipment is designed to operate within certain limits. Air conditioning and heating equipment is no exception and, if not properly maintained, it will exceed its design limitations with the result being equipment failure.
