Does duct cleaning remove mold?

Yes, professional duct cleaning can remove mold growth inside your ducts, but it’s important to address the source of moisture at your air-con units to prevent recurrence.
How much does duct cleaning cost in the UAE?

The cost varies depending on the size of the system, but it typically ranges from AED 500 to AED 2,000.
What is included in a professional duct cleaning service?

A professional service typically includes cleaning supply and return air ducts, registers, grilles, diffusers, coils, and the air filter on handling units (AHU).
Can duct cleaning reduce energy costs?

Yes, clean ducts improve airflow, allowing your AC system to operate more efficiently and reducing energy consumption.
Is duct cleaning necessary if I have a new AC system?

While new systems may not need immediate cleaning, it’s still important to inspect and clean ducts if there’s construction debris or dust from installation.
What is the process of duct cleaning?

The process involves inspecting the ducts, using specialized tools to dislodge debris, and vacuuming out the contaminants with a high-powered vacuum then applying a disinfectant fog to the ducts.
Can duct cleaning help with pest infestations?

Yes, duct cleaning can remove pest droppings, nests, and debris, but you may also need pest control services to address the root cause.
