What does air duct cleaning include?
The scope depends on the home's duct layout and the provider's inspection. Ask the provider which accessible supply ducts, return ducts, registers, grilles, and HVAC components are included in the quoted work.
How do I know whether my ducts need cleaning?
Visible debris around registers, recurring dust after renovation, or an inspection finding can be reasons to ask about cleaning. Weak airflow or odors can also have causes outside the ductwork, so an inspection is useful.
Will duct cleaning fix weak airflow?
Not always. Weak airflow can be caused by a dirty filter, blocked register, duct damage, duct leakage, or an HVAC equipment issue. The provider can identify whether cleaning is relevant to the problem.
What should I ask before scheduling duct cleaning in California?
Ask what areas will be inspected, what the cleaning scope includes, and whether the provider finds any duct damage or moisture concerns. Confirm the provider's licensing and insurance information when applicable to the work.
Should I replace my HVAC filter before duct cleaning?
A clean filter helps protect HVAC equipment and supports airflow. Ask the provider whether to replace it before or after the inspection based on the condition of the system.
Can an air duct cleaning company work around my HVAC brand?
Independent providers can inspect the ductwork and accessible components connected to many common HVAC brands. The provider who comes out can identify the system and explain what can be cleaned without making changes to the equipment.
Do I need cleaning or duct sealing?
Ductwork cleaning removes dust and debris from accessible ducts. Duct sealing addresses gaps or disconnected sections that may allow air to escape, and a duct inspection can help distinguish between the two needs.
What is the difference between duct cleaning and dryer vent cleaning?
Commercial air duct cleaning or home duct cleaning concerns the HVAC passages that distribute conditioned air. Dryer vent cleaning concerns the exhaust route from a clothes dryer, where lint buildup can collect.
Can sanitizing or deodorizing remove mold growth?
Sanitizing and deodorizing are separate services that a provider may discuss after an inspection. If mold growth or mildew is suspected, ask the provider what was found, what work is proposed, and whether additional evaluation is needed.
