How Often and Why Should You Disinfect Your HVAC?

How often should you disinfect your HVAC?

It depends on your component, but ideally, you should have your HVAC cleaned annually. And, filters should be cleaned or replaced once a week.

Why you should disinfect your HVAC during the pandemic:

Indoor pollutants, mold, mildew, airborne pathogens, and bacteria can thrive inside your HVAC system. Not only will they affect the performance of your HVAC, but they can also spread harmful viruses. Maintaining a healthy indoor environment is vital for homes and offices, especially during the coronavirus outbreak.

  1. It improves indoor air quality and promotes health. When air flows through the ventilation system, it can bring allergens, mold, mildew, and other contaminants with it. While the air filters are designed to catch these particles, some of them still manage to pass through the space between the fibers in the filter. By cleaning your HVAC, you can get rid of these harmful particles, improving the quality in your office or residence.
  2. It maintains a comfortable temperature. When your HVAC is cleaned, debris is removed, and you’ll notice significantly better performance from your HVAC system. You’ll get better heating and air conditioning.
  3. It cuts costs on repairs. When your HVAC’s functionality is limited, more stress is put on your system, leading to early wear and tear. Save on costs for repair by regularly cleaning your HVAC system. If you keep postponing its maintenance, you’ll eventually have to pay a large amount of money for replacement parts, and in some cases, you might have to buy a completely new unit/system.


There’s no escaping it -- over time, your HVAC will collect dirt and dust, which will make the air around you unsafe. Keeping your HVAC’s air ducts and vents clean should be done regularly to breathe clean air and avoid potentially dangerous bacteria.

Having your HVAC system professionally sanitized by an HVAC engineer can improve airflow, decrease the risk of breeding harmful bacteria, save you from expensive repairs, and make the indoor environment feel more comfortable. By having your heating, ventilation, and air conditioning system disinfected, you also reduce the risk of getting infected with COVID-19.
