Although there is currently no research that supports that Covid-19 (Coronavirus) can be directly transferred through air conditioning systems, there is similarly no research to say that it can’t.
What we do know is that HVAC systems can help control the spread of the virus.
A study published in the New England Journal of Medicine, shows that the virus could survive in droplets for up to three hours after being coughed out into the air. Fine droplets between 1-5 micrometres in size – about 30 times smaller than the width of a human hair – can remain airborne for several hours in still air.
This means that the virus circulating in unfiltered air conditioning systems will only persist for a couple of hours at the most, especially as aerosol droplets tend to settle on surfaces faster in disturbed air.
In addition to the benefits of unfiltered air movement, airborne contaminants can be minimised, if not eliminated, by proper and effective filtration and regular cleaning and maintenance of hvac systems. A clean hvac system is an essential part of a healthy building and it is highly recommended that any air conditioning systems are cleaned to industry best practice as a preventative measure during these uncertain and unprecedented times.
Here at Torr we are offering a 2 stage deep cleaning treatment using the 2 most effective cleaning products as recommended by air conditioning manufacturers and suppliers alike. These products are:
- Antiviral
- Antibacterial
- Antifungal
- Germicidal
The process requires significant dismantling of the air conditioning indoor units to provide unhindered access to the heat transfer coil. Depending on the type of air conditioning system, the treatment can take between 1-3 hours per unit. After the final treatment and rinsing, the air conditioner is left with a pleasant lemon smell and can be used immediately.
This deep cleaning process can be done as one off treatment before staff return to their workplaces, at predetermined intervals during the coronavirus pandemic or as part of an ongoing preventative planned maintenance (PPM) agreement.
