Asbestos in HVAC Systems: What Every Contractor Should Know.
The Hidden Asbestos Risk in HVAC Systems
For decades, asbestos was commonly used in HVAC systems across Southern California. It can be found in duct insulation, mastic, duct boots, and transite piping. These materials were valued for their heat resistance — but today, they’re a major liability if disturbed.
When contractors start HVAC replacement or repair without first testing for asbestos, they risk worker exposure, regulatory fines, and costly project delays.
Where Asbestos Is Most Common in HVAC
Duct insulation & tape – Older systems often used asbestos wraps.
Duct boots & connections – Frequently contain asbestos mastic.
Transite (asbestos cement) piping – Used for HVAC exhaust and furnace flues.
Mechanical rooms – Asbestos may be present in gaskets, insulation, or sealants.
Why HVAC Contractors Can’t Ignore It
Regulatory Compliance: South Coast AQMD Rule 1403 and DIR requires licensed asbestos contractors to properly remove asbestos.
Project Delays: Discovering asbestos mid-job can halt work until a licensed abatement contractor is brought in.
Improper Removal: May cause harm to employees and clients it may also cost your company thousands in damages.
Health Risks: Cutting or disturbing asbestos ducting releases microscopic fibers linked to lung disease.
Client Confidence: Homeowners and building managers expect safe, compliant solutions.
