What Duct Cleaning Involves
Duct cleaning involves cleaning out dust, debris, and allergens from your HVAC system’s ductwork. Duct cleaning typically consists of inspecting the ducts, employing specialized tools like vacuum systems, and disinfecting surfaces to improve air quality.
When You Need Duct Cleaning
You should evaluate duct cleaning if you see high dust accumulation in your home, experience respiratory issues, or have newly completed a renovation. However, if your ducts are free of debris, frequent cleaning is often unwarranted.
The Cleaning Process
The duct cleaning process typically follows these steps:
- Assessment of the duct system
- Preparing the workspace to protect your home
- Using powerful vacuums to extract debris
- Cleaning return registers and grilles
- Applying antimicrobial treatments to prevent mold growth
This whole process typically lasts 3-6 hours, depending on the extent of your system.
