Most people think that HVAC sanitization just means changing the filters. While cleaning the filters is part of HVAC disinfection, you should also think about the air ducts, fan coil units, and air handling units. Behind your HVAC is a huge system that can breed bacteria.

And it doesn’t stop there. HVAC disinfection should go hand-in-hand with overall cleaning. This means disinfecting surfaces around your HVAC system, looking out for molds and water leaks, and training staff to practice proper hygiene.

In older homes and basements, years of dust can collect between stone foundations and wooden panels, building up more debris in your HVAC. You will have to regularly clean the area using a powerful vacuum, to prevent dust from clogging your unit.
