Each time heating and cooling equipment is used in the office, any dirt, allergens, and debris in the ductwork could flow through the vents and registers and contaminate the air supply. Investing in regular HVAC service will prevent the likelihood of this happening. To be better prepared to care for the needs of your workspace, here are the answers to a few common questions about commercial duct cleaning. 

What You Need to Know About Duct Cleaning

How Often Should Ducts Be Cleaned?

An HVAC service technician should inspect your property’s ductwork annually for cleanliness. They will remove the vent covers and use flashlights to check the filters, as well as the ducts, for dust, pollen, and dirt buildup. If it’s been more than five years since your ducts were last cleaned, having your equipment serviced will improve ventilation and help reduce energy costs. 

What Cleaning Products & Equipment Should Be Used?

HVAC service specialists use commercial-grade vacuums to remove debris from ductwork. As the vacuum pushes air through the channels, the pressure helps dislodge debris clinging to surfaces. If mold, bacteria, or viruses are present, the technician might wash down the ducts with antimicrobial chemicals to disinfect the system. 

How Long Does It Take to Clean Ductwork?

How long the service will take greatly depends on the size of your space and how many ducts are installed. A technician will have to find access points to the ducts and disassemble different components to place the vacuum in the channels. Typically, you can expect the HVAC service appointment to last between four and six hours. 

What Could Happen Without Regular Duct Cleaning?

If the ducts aren’t cleaned, it increases the chances of employees, clients, and anyone else who visits the space getting sick. When ducts are covered in dust, mold, and additional grime, microscopic pores could get pushed into the air. Breathing in the allergens could cause asthma attacks, sinus problems, headaches, and additional discomfort.
