How often i need to clean my air duct in San Antonio ? Why is it so important to clean my air duct ?

In San Antonio, it is recommended that you clean your air ducts every 2-3 years.

It is important to keep your air ducts clean to ensure the health and safety of everyone at home! Things like dirt, dust, mold caused by moisture, and even soot from the HVAC system engine can accumulate in your air ducts over time. If not cleaned regularly, these pollutants will mix with the air being distributed through your air ducts and into your home! This can be especially harmful for people with underlying conditions such as allergies or asthma.
