With winter here, if your HVAC system isn’t up to the mark in preventing the spread of flu and colds, the loss in productivity of your employees will hurt you. Due to COVID-19, it’s far more important to have your establishment running a proper commercial HVAC system with advanced filtering systems and other measures that help prevent the spread of viruses and flu. The financial burden of spreading COVID-19 around the workplace is significantly higher than spreading normal flu or cold.

Therefore, if your workplace has poor ventilation or an ill-maintained HVAC system, the chances of spreading flu and viruses increase substantially. And so, today, we’re going to look at some of the best practices involved when it comes to preventing the spread of COVID-19 along with other airborne diseases in your office with a commercial HVAC system.


Poor Air Ventilation

Before diving into the specifics of your commercial HVAC system, it’s worth remembering that the best thing you can do to prevent bacteria and viruses from overrunning your workplace is to improve the ventilation of your building or office.

Most modern buildings are tightly packed with each other and poorly furnished, thereby making the ventilation within them hard to maintain and leads to a lot of spread of diseases and flu. In most cases, the air quickly becomes stagnant and collects bacteria, mold, viruses, and other microorganisms which cause irritation and allergies. On top of this, if your HVAC system has poor filters, this stagnant air circulates through the building, along with all the microorganisms and disease-causing bacteria.

Without proper ventilation, viruses and bacteria quickly accumulate and grow in numbers eventually leading to low quality air circulating your workspace. Therefore, the first step towards a healthier workspace to prevent airborne diseases is to improve the ventilation.


Preventing Airborne Illnesses with a Commercial HVAC System

Once you’ve improved the ventilation in your workspace, you can rely on your commercial HVAC unit to handle the rest of the job. Here’s how your commercial HVAC system can help prevent diseases and how you can maintain it properly to ensure it does its job properly.

1.      Replace Filters Regularly

The filters in your commercial HVAC system serve as the first line of defense against harmful bacteria and other organisms. Your certified AC services & repair specialist can advise you on how often you should change your air filters and the types you should use.

Without the right filters, you might end up bringing down the efficiency of your heating and cooling system and end up damaging your equipment. Therefore, you should always consult with your AC maintenance & repair specialists before purchasing or replacing air filters.

2.      Schedule Regular Maintenance, Tune-ups, and Cleaning for Your Condenser and Gas Furnace

The condenser and gas furnace in your commercial HVAC system will get dirty over time. Due to the wet and damp environment around the condenser, it welcomes bacteria and mold growth. Therefore, you need to schedule regular maintenance and inspections to ensure that the air conditioning units are clean, and don’t end up becoming a spawn for bacteria and mold.

On top of this, you need to tune-up parts of your HVAC system and ensure everything is working properly, and efficiently. With a cleaner system, you will be able to keep pollen, dust, and mold out of the main system, and out of the air circulating your building. This reduces air impurities and helps prevent airborne illnesses.

3.      Air Duct Repairs and Air Duct Cleaning

Air ducts are yet another breeding ground for mold and bacteria. Therefore, to prevent the spread of airborne illnesses and to keep the air circulating in your workspace clean, you should invest in regularly cleaning your air ducts. On top of regular maintenance, you should keep an eye out for leaks and damages and get them fixed through hair duct repairs.

With clean, undamaged air ducts, you will bring down the chances of contracting airborne diseases due to stagnant or impure air significantly.

4.      Advanced Air Filtration and Purification Techniques

With the rise of COVID, we now have access to better air purification methods in the form of UV light filtration and bi-polar ionization. If you install any of these measures in place, you will be able to significantly reduce the risk of transmitting the COVID-19 virus in your workspace.



With all these measures in place, you can bring down the chances of airborne illnesses. Moreover, you can keep your employees from becoming sick due to workplace illnesses.
