What Duct Cleaning Involves
Duct cleaning is cleaning out dust, debris, and allergens from your HVAC system’s ductwork. It typically entails inspecting the ducts, employing specialized tools like high-powered vacuums, and sanitizing surfaces to boost air quality.
When You Need Duct Cleaning
You should consider duct cleaning if you notice high dust accumulation in your home, experience respiratory issues, or have newly completed a renovation. However, if your ducts are well-maintained, constant cleaning is often unwarranted.
The Cleaning Process
The duct cleaning process usually follows these steps:
- Pre-cleaning evaluation of the duct system
- Setting up the workspace to protect your home
- Using vacuum systems to pull out debris
- Cleaning supply registers and grilles
- Disinfecting to prevent mold growth
This whole procedure typically lasts 3-6 hours, depending on the extent of your system.
