HVAC Cleaning and Restoration

HVAC System Cleaning, Decontamination and Restoration

Air Restore (NZ) Ltd is a high-tech HVAC cleaning, decontamination and restoration company. Duct cleaning is a misleading term, as it implies just the ducting network of the HVAC system is cleaned. To yield positive results, total system cleaning, decontamination and restoration of all ductwork, fans, coils, internal insulation and other components may be required.

Equipment and Procedures

To protect your occupied space and building occupants from contamination, the actual cleaning and decontamination process is conducted under negative air pressure. The contaminants are drawn into a large HEPA (high efficiency particulate arrestive) filtration machine that is 99.97% efficient at 0.3 microns. The source removal of contaminants without the use of negative air machines poses a risk of cross contaminating the building and increasing the risk of occupant exposures to contaminants found in the air handling system.

To validate the effectiveness of cleaning and decontamination projects we follow the guidelines laid out in NADCA Standard ACR 2006 Assessment, Cleaning, and restoration of HVAC systems. We take before and after photographs of all systems cleaned and provide a comprehensive maintenance report with each project.

Our Guaranteed Results:

  • Eliminate the risk of IAQ related problems from contaminated HVAC systems and components such as coils, condensate drain trays, internal insulation etc.
  • Cooling coils heat transfer ability is restored and the pressure drop across the coil is reduced resulting in a saving on fan energy.
  • Overall system performance will increase and energy consumption will be reduced.
  • Control system components (sensors & dampers) will respond better which is particularly important in the event of a fire.
  • The best HVAC refurbishment NZ services, bar none.

Kitchen Exhaust Cleaning

Kitchen Exhaust Cleaning

Kitchen hoods, ducting, and fans gather grease during the cooking processes that accumulates. This accumulation of flammable grease is the cause for most kitchen fires and poses many potential risks to building owners and managers.

Why clean kitchen exhaust systems?

  • To reduce the risk of fire hazards – prevention of high grease buildup.
  • To adhere to fire, health and safety guidelines – a legal obligation to promote building safety.
  • To increase the efficiency of the exhaust system – a clogged system requires more energy to run, and is inefficient.
  • To save energy whilst running the system – a system which is extremely clogged would not be able to draw air efficiently, and would be running inefficiently.
  • To provide a cleaner and healthier environment – removal of grease and dirt reduces the growth of bacteria and promotes a cleaner air flow.
  • To provide a safer and more comfortable workplace – the removal of odours and fumes leaves the air cleaner to breathe.
  • To save money – the cost incurred in cleaning the system on a one-off basis, is a long and involved process, whereas to clean a system which has been regularly serviced, is a quicker and easier job.

Why Choose Us?

Air Restore (NZ) Ltd provides kitchen exhaust cleaning services with our client’s needs in mind. We understand that there are many implications to consider such as conducting the work around the operational hours of restaurants. We therefore provide a cleaning and maintenance schedule that suits our client’s individual needs and budget.

HVAC Hygiene Audits

HVAC Hygiene Audits

Heating, Ventilation and Air Conditioning (HVAC) system hygiene is an important issue for all building owners and managers. Maintaining acceptable levels of HVAC hygiene reduces the potential for a degradation of the Indoor Air Quality which is essential for enhancing occupant health in any built environment.

Air Restore (NZ)Ltd understands all of these issues. We offer an audit service for our clients that essentially assesses the clients HVAC systems hygiene and quantifies the associated risk of identified problems.

Our HVAC Audits Covers:

  • Identify issues to be addressed to ensure compliance with the relevant standards such as AS/NZS3666.2:2002, Air-Handling and water systems of buildings-Microbial Control, Part 2: Operation and Maintenance. Compliance indicates due diligence.
  • To conduct a risk assessment based on the findings including the understanding of risk relative to the occupied use of the areas served by the system.
  • To identify HVAC systems and components in need of cleaning, decontamination and restoration to reduce risk including financial loss.
  • Identifying issues before they become problematic and costly.
  • Prepare budgets for work requiring attention either immediately or down the track.
  • Based on the assessment we can advise on future inspection schedules for ongoing risk management.

Hygiene and Healthcare Facilities

HVAC Hygiene and Healthcare Facilities

The overall risks associated with HVAC system cleaning, decontamination and restoration projects in healthcare facilities depends on patient risk factors as well as various processes and procedures that take place during the course of the project. The patient risk with the greatest consequence is infection followed by allergic reaction or irritation.

The importance for assessing the risks and developing appropriate contaminant control procedures is highlighted by the fact that patients in health care facilities whose immune systems function poorly because of disease or medication are particularly vulnerable to airborne viable particle contaminants.

The primary concern during HVAC decontamination and cleaning projects in health care facilities is the dissemination of airborne contaminants, especially fungal spores, e.g. Aspergillus. Fungal spores, while harmless to most, can lead to serious morbidity and mortality in immune suppressed populations. Implementing infection control measures during these projects is imperative to reduce the risk of airborne and environmental contamination. Identifying strategies necessary to eliminate this type of contamination should be a major focus of all infection control staff at health care facilities and to those hospital engineer’s conducting and managing the project.

One of the major requirements of a successful project is adequate planning prior to the commencement of the project and continuous communication between the hospital engineers, infection control staff and the hospital staff in the occupied areas being served by the systems being decontaminated.

Contaminant control strategies selected for use during any HVAC decontamination and cleaning project depend on several factors: project size, type and potential amount of contaminants, building occupancy characteristics and consequences of patient/occupant and equipment exposure.

Air Restore (NZ) Ltd is more than just a duct cleaning company. We can help clean, decontaminate and restore your HVAC systems without compromising the air quality in the areas they serve.
