Mechanical ventilation bringing air into occupied spaces.

Keep on top of the inspections, maintenance and records your building needs. We help Auckland building owners, property managers and facilities teams look after their SS9 mechanical ventilation and air conditioning systems.
Warm It & Cool It is an Auckland Council-approved Independent Qualified Person (IQP) for SS9 systems, excluding cooling towers. We work to your building’s Compliance Schedule and explain what needs attention.
The exact checks depend on the systems listed in your Compliance Schedule.
Mechanical ventilation bringing air into occupied spaces.
Extract fans and associated kitchen, toilet or general ventilation systems.
Commercial heating and cooling equipment. All systems, all brands.
Fans, motors, filters and associated components.
Relevant ductwork, air pathways and ventilation outlets.
Checks on the condition and operation of the specified equipment.
Your Compliance Schedule tells us which systems need checking and how often. We use it to plan the relevant SS9 visits, maintain your equipment and keep a record of the work.
Managing more than one building? We can also organise ongoing SS9 inspection and maintenance across your property portfolio.


If an inspection finds an issue, you need a clear way forward. Our air conditioning and ventilation technicians can investigate the fault, explain the work needed and help with repairs within our services.
A failed fan, blocked filter or control fault doesn’t always mean replacing the whole system. We look at what’s causing the problem and discuss a practical solution.
Your building’s annual Building Warrant of Fitness (BWOF) relies on the required procedures being completed for its specified systems. We provide SS9 support for the systems within our IQP scope.
Form 12A can be issued only when the relevant inspection, maintenance and reporting procedures have been fully completed over the previous 12 months.
We provide the appropriate certificate for SS9 systems within our scope. Your building may also need certificates for other specified systems.
Clear inspection and maintenance records help you, your property manager and your BWOF provider keep track of completed work.
Clients choose us to provide HVAC maintenance, and stick with us.
Helpful answers
Plain-language answers for building owners and property managers arranging SS9 maintenance.
SS9 refers to mechanical ventilation and air conditioning systems listed as specified systems on a building’s Compliance Schedule. A normal air conditioning service focuses on the equipment. SS9 work follows the inspection, maintenance and reporting procedures recorded on the schedule, with IQP involvement where required.
Send us your building address and a copy of the current Compliance Schedule. Recent inspection reports, maintenance records and the BWOF due date are also helpful. We’ll review the information and confirm what we can cover within our IQP scope.
The required procedures and frequencies are set out in your building’s Compliance Schedule. We plan the relevant SS9 visits around that schedule rather than applying the same interval to every property.
For SS9 systems within our IQP scope, we can issue Form 12A only when the relevant inspection, maintenance and reporting procedures in the Compliance Schedule have been fully completed over the previous 12 months. It supports the building owner’s annual BWOF process; other specified systems may require separate certificates.
We explain the issue, record what needs attention and discuss the work required. Our HVAC team can help with repairs and maintenance within our services. Certification still depends on the relevant Compliance Schedule procedures having been fully completed.
We can review your Compliance Schedule and existing service records to establish the requirements within our IQP scope. If you’re changing providers or taking over a property, contact us early so we can discuss the required inspections, records and any outstanding work.
Tell us about your building and the SS9 work you need. We’ll review the requirements and help you organise the next step.
Have your Compliance Schedule and BWOF due date handy if you can.
