What Duct Cleaning Involves
Duct cleaning involves removing dust, debris, and allergens from your HVAC system’s ductwork. Duct cleaning typically entails inspecting the ducts, employing specialized tools like vacuum systems, and sanitizing surfaces to boost air quality.
When You Need Duct Cleaning
You should evaluate duct cleaning if you notice significant dust accumulation in your home, experience respiratory issues, or have newly completed a renovation. However, if your ducts are clean, constant cleaning is often unwarranted.
The Cleaning Process
The duct cleaning process generally follows these steps:
- Pre-cleaning evaluation of the duct system
- Preparing the workspace to protect your home
- Using vacuum systems to extract debris
- Cleaning return registers and grilles
- Applying antimicrobial treatments to prevent mold growth
This whole procedure can take 3 to 5 hours, depending on the scale of your system.
