1. Return Ducts
Return ducts pull indoor air back to the air handler for conditioning. Because they draw from every room, return ducts capture the widest variety of contaminants — dust, pet dander, pollen, cooking residue — making them the component with the heaviest debris load.
2. Evaporator Coils
The evaporator coil cools and dehumidifies incoming air. Moisture condenses on coil fins during operation, and dust accumulates on the damp surface, reducing heat transfer efficiency and providing ideal conditions for mold growth.
3. Blower Fan
The blower fan circulates conditioned air throughout your home. Debris on fan blades unbalances the assembly, creating vibration, noise, reduced airflow, and increased energy consumption.
4. Heating Chamber
The heating chamber can accumulate dust, soot, and combustion residues that reduce heating efficiency and create fire hazards when left untreated.
5. Plenum Box
The plenum box is the central distribution chamber where all duct branches meet the air handler. It is the highest concentration point for contaminants because air from every return converges here.
6. Supply Ducts
Supply ducts deliver conditioned air to registers in each room. Particles settle on interior surfaces and redistribute during operation.
7. Register Boxes
Wall and ceiling cavities housing your registers are cleaned to eliminate accumulated dust and debris.
8. Grills and Vent Covers
All covers are removed, washed with soap and water, dried completely, and reinstalled.
The average residential cleaning takes approximately 7 hours because each component receives individualized, thorough treatment.
