Q: What is the difference between general pressurisation and smoke exhaust systems?

We fix it free and credit $200 off your next invoice.Pressurisation systems (e.g., stair pressurisation) keep smoke out of safe areas.Smoke exhaust systems actively remove smoke from fire zones to improve visibility and reduce heat. Both must work in coordination with your fire detection system to provide effective smoke control.

Q: What standards govern HVAC and fire safety maintenance?

The main standard is AS 1851-2012 – Routine Service of Fire Protection Systems and Equipment. For HVAC systems specifically, compliance must also align with the Building Code of Australia (BCA), National Construction Code (NCC), and Australian Standards such as AS 1668 (mechanical ventilation and smoke control).

FREQUENTLY ASKED QUESTIONS

FAQ’S

What is AFSS and why does it matter for my building?

The Annual Fire Safety Statement (AFSS) is a legal requirement that confirms your building’s fire safety measures have been inspected, tested, and are compliant. Both fire protection systems and mechanical/HVAC systems play a role in ensuring occupant safety.

How do HVAC systems relate to fire protection?

Your HVAC system connects directly with fire systems through interfaces such as smoke detectors, dampers, and fans. During a fire event, these systems need to work together seamlessly to control smoke and allow safe evacuation.

Why do I need interface testing?

Interface testing checks that your fire and HVAC systems “talk” to each other properly. For example, when a fire alarm activates, we confirm smoke exhaust and stair pressurisation fans start, supply fans stop, and fire dampers close. Without proper testing, these critical safety functions may fail and occupants may be left in an unsafe building.

What is stair pressurisation and why is it important? 

Stair pressurisation systems are designed to keep stairwells smoke-free during a fire by maintaining higher air pressure in the stairwell compared to the fire-affected areas. This ensures occupants have a safe escape path and firefighters have clear access. These systems must be routinely tested in line with AS 1851-2012.

Pressurisation systems (e.g., stair pressurisation) keep smoke out of safe areas.
Smoke exhaust systems actively remove smoke from fire zones to improve visibility and reduce heat.
Both must work in coordination with your fire detection system to provide effective smoke control.

Why are fire dampers and smoke dampers critical to HVAC safety?

Fire and smoke dampers automatically close when fire or smoke is detected, preventing the spread of flames and smoke through ductwork. Without them, HVAC ducts can become a pathway for fire, compromising the safety of the entire building.

What is a VSD (Variable Speed Drive) and why does it matter in HVAC?

A VSD controls the speed of motors in fans and pumps. This improves energy efficiency, reduces wear, and ensures systems can ramp up or down during fire mode (e.g., smoke exhaust fans moving to full speed). Testing VSD response is part of compliance.

Can 2020 HVAC undertake mechanical air handling maintenance AND fire protection?

Yes. With 2020 Fire Protection and 2020 HVAC Services working together, we streamline your AFSS process. Instead of coordinating multiple contractors, you get one integrated team who understands both sides — saving time, cost, and reducing compliance risks.

Does this make my AFSS easier?

Absolutely. Having both fire and HVAC testing under one roof means less scheduling hassle, fewer delays, and a smoother sign-off process. Our goal is to give you a complete, compliant, and headache-free AFSS experience.

What standards govern HVAC and fire safety maintenance?

The main standard is AS 1851-2012 – Routine Service of Fire Protection Systems and Equipment. For HVAC systems specifically, compliance must also align with the Building Code of Australia (BCA), National Construction Code (NCC), and Australian Standards such as AS 1668 (mechanical ventilation and smoke control).

What’s the difference between essential services maintenance and general HVAC maintenance?

Essential services (e.g., stair press, smoke exhaust, fire mode dampers) are legally required to be tested and reported for AFSS compliance.
General HVAC maintenance (e.g., filters, coils, refrigerant, belts) ensures comfort, energy efficiency, and equipment life.
Both are necessary, but only essential services impact your AFSS compliance directly.

How often should my air conditioning system be serviced?

We recommend routine servicing every 6 months, depending on the type of system and how heavily it’s used. Regular servicing helps extend the life of your equipment and ensures maximum efficiency. Some system maintenance is required by AS 1851-2012, and we can tailor your maintenance program to match both your operational and compliance needs.

What are the risks of not maintaining my HVAC system?

Neglecting maintenance can lead to higher energy bills, poor air quality, breakdowns, and costly repairs. It can also impact compliance with workplace health and safety standards and lead to an unsafe building for your occupants.

How does poor HVAC maintenance affect indoor air quality (IAQ)?

Dirty filters, blocked coils, and poor airflow can increase CO₂ levels, spread dust, mould, and bacteria, and cause occupant discomfort or illness. Regular servicing ensures your system provides clean, fresh, and safe air.

Do I need to keep service records for my HVAC equipment?

Yes. Keeping accurate maintenance records not only helps with warranty but also ensures compliance with industry standards and building regulations.

How much does HVAC servicing cost?

The cost depends on the size, type, and condition of your building and system, as well as the legislated service requirement. We provide clear, tailored quotes so you know exactly what to expect.

You say you provide “less headaches”—what happens if I don’t feel that’s the case? 

Our aim is to deliver clear communication, reliable service, and minimal disruption. If you feel we’ve fallen short, we want to know so we can make it right and ensure your experience is better than the last provider. Every communication will have the opportunity for you to give live feedback direct to our senior management team.
