“Vaccination is vital,” says AIRAH CEO Tony Gleeson, M.AIRAH. “But for reopening to succeed, we must support it with other measures. Now that there is consensus that SARS-Cov-2 is airborne, why aren’t we doing more to address ventilation? This is particularly important in buildings such as schools, nursing homes, offices, shopping centres, cafés and restaurants.”
“There is no evidence that COVID-19 can be spread through HVAC systems, however having your HVAC system set to allow more air circulation in common areas and limiting or not using recirculated air and increasing outside air intake, if possible, may help minimise the risk of COVID-19 spreading in your workplace.”

Before workers return to work and the HVAC system has been temporarily shut down, you must abide by the health and safety regulations to ensure your HVAC system is inspected, serviced and maintained.
A qualified HVAC technician should provide you with a letter of inspection to ensure ongoing building compliance is met.
CFM Air Conditioning can provide you with a letter of inspection if we attend your premises and inspect, and or service your heating, ventilation and cooling system.

The HVAC system in my workplace was shut down during Covid-19 restrictions. What Are the health risks to health once restarted?
HVAC systems that have been shut down temporarily should be correctly maintained and inspected by CFM Air Conditioning technicians in-line with the building HVAC regulations and standards.
Cooling towers and condenser water systems can build up corrosion, water can become stagnant, bacteria can grow and indoor air quality compromised.
It is important offices and building managers ensure HVAC systems are serviced prior to restarting.

Preventative Maintenance is also required for insurance purposes.
Short-term exposure to carbon monoxide usually results in flu-like symptoms: nausea, headaches, dizziness, fatigue. Long-term exposure can eventually lead to unconsciousness or death. If you are concerned contact CFM Air Conditioning and we can test the unit for you.
1. The age of the current system. Today, any system that is more than ten years old is probably behind the times in terms of efficiency.
2. Does the existing system provide the level of comfort that you want? There is a growing difference between “builder grade” and consumer choice in what a system can offer in terms of comfort and convenience.
3. How much will the repairs cost, and how many more repairs will you need in the future? Is keeping an older system operational worth the time, the money and the inconvenience?
4. Replacing older equipment with new technology can typically have a payback of less than 5 years.
Here are problems to watch for, and tips for maintaining indoor air quality:
• Check for wet spots and condensation in your building. Mould grows rapidly in a wet environment, so scrub and dry wet areas within 48 hours.
• Keep indoor humidity low.
• If you notice condensation, reduce moisture levels.
• Repair leaks, increase ventilation if outside air is cold and dry. Dehumidify, if outdoor air is warm and humid.
• Raise the surface temperature through better insulation or by increasing air circulation.
• Clean the heating, ventilation, and air conditioning drip pans.
• Perform routine repairs and cleaning of your HVAC system.
• Is the HVAC system well-maintained? Clean dirty coils, which reduce cooling and dehumidification. Clogged pans may hold standing water. Leaks in the mechanical system let moisture enter the building.
• Is the indoor air quality system being operated properly? Make sure the cooling fans run at a moderate speed. Sometimes air velocity is set too high, because spaces are not adequately cooled. But the result can be higher humidity levels in a building.
Preventive maintenance is a good investment and it is your assurance that your HVAC system will function properly. On a regular basis, heat pumps and air conditioners should have a tune-up by professionals. Gas-fired equipment function with greater efficiency should be maintained every other year. Inspections on boiler and furnace systems should include ductwork, pipes, dampers, valves, the chimney, registers, radiators, pumps, blowers, fuel lines, the gas meter, oil tank and every part of the actual furnace and boiler.
Meanwhile, heat pump and air conditioning unit inspections should also include inspections of the fan, compressor, indoor coils, outdoor coils and refrigerant lines. It is required to ensure compliance to relevant standards and is an essential services code requirement.

Today’s modern central air conditioners are significantly more efficient than old models. Part of this is due to the federal push for Australian energy independence and a drive to reduce greenhouse gases. The federal Energy Star program mandates that the models you look at when upgrading an air conditioner have met MEPPS Minimum energy performance criteria, this is easily obtainable, you will conserve natural resources and lower atmosphere-fouling emissions.
This efficiency extends to the new refrigerant, R-410A, which provides impressive cooling power while not chipping away at the ozone layer. Modern equipment built to handle this newer coolant (as opposed to the old, discredited R-22/Freon) will deliver ample cool air with greater energy efficiency than your old system.
