- The indoor air quality characteristics of the house
- Previous duct repairs

When Should You Inspect Ductwork More Often Than Once a Year?
While annual professional ductwork cleaning isn’t always required for every house, there are some house conditions that may warrant more frequent ductwork cleaning.

- You have issues with heating up or cooling down that aren’t making sense to you.
- Large repair jobs have been performed on the HVAC system.
- You’ve remodeled an area containing ductwork.
- You think you’ve damaged ducts.
- A continuous problem in your home is ventilation.
- You have seen an unusual spike in energy costs.
- There are signs of moisture around ducts or HVAC equipment.

What Are the Warning Signs That Your Ductwork Needs Inspection?
There are a number of indications you can get from your HVAC system that something has gone wrong with the ductwork.
Watch for:
- Decreased ventilation
- Unusual dust build-up
- Loose or damaged parts
- Unusual odors

What Happens During a Professional Ductwork Inspection?
Professionals inspect ductwork much more thoroughly than by observing the ductwork system alone.
The technician can verify:
- Insulation
- Registers and grilles
- Airflow
- Leaks and/or damage apparent to the naked eye
- Evidence of moisture
- Tolerate some signs of pests or debris
- The state of equipment and accessible ductwork
The technician can also inspect duct interaction with the HVAC system. Broken or leaky ductwork can reduce effectiveness in how it circulates air throughout the house and can cause home cooling and heating systems to perform less effectively.
Should Ductwork Be Cleaned During Every Inspection?
An inspection determines if there are issues to be addressed, and cleaning eliminates particles of dust and debris or other issues when cleaning is appropriate. A regular ductwork inspection frequency can also help with knowing when to clean the system.

- Evidence of pests
- Suspected contamination
