Mesothelioma in HVAC Technicians and Asbestos Exposure
HVAC workers have a higher risk of mesothelioma from asbestos exposure. Asbestos was used in insulation, ductwork, gaskets, and other HVAC components in buildings until the late 1970s. Many older buildings still contain asbestos, putting technicians at risk during repairs or maintenance.

Asbestos Exposure for HVAC Technicians
The construction industry used asbestos in nearly every building component in commercial and residential structures until the late 1970s, when the government began passing asbestos laws and regulations restricting its use. Today, the industry uses alternative materials in all building products, but HVAC workers who were exposed to asbestos 20, 30, or more years ago are still developing mesothelioma. HVAC technicians also risk continued exposure when working in buildings constructed before 1990.
Asbestos exposure occurs during cleaning, maintenance, repair, installation, or removal of HVAC systems and disposal of HVAC products that contain asbestos. HVAC technicians must often work in tight spaces with poor ventilation, such as attics and crawl spaces, increasing the concentration of airborne asbestos.
Asbestos in HVAC Insulation
Due to its superior temperature and fire resistance, asbestos was a primary component in various insulation materials used in HVAC systems. It insulated HVAC system parts that generated high heat, such as heating elements. Any components used to prevent fires, such as fire blankets and fire panels, were also made of asbestos.
Workers may have been exposed to asbestos in pipe wrapping, boiler insulation, fire blankets, and fire panels. Asbestos becomes dangerous when fibers become airborne, which can occur when a worker damages a material containing it. HVAC technicians may have been exposed to asbestos in insulation while doing the following:
- Cutting pipes with asbestos insulation or fire wraps
- Installing boilers
- Repairing or replacing boiler doors, covers, and piping
- Installing, cutting, or removing fire blankets
- Repairing or replacing heating elements
Asbestos in HVAC Machinery
Asbestos has qualities that make it valuable in numerous machinery parts. It is non-conductive to electricity, resistant to corrosion, flexible, strong, and waterproof. These qualities made it useful for improving the performance of gaskets and seals, preventing leaks, and insulating against electricity. As a result, HVAC technicians may have experienced occupational asbestos exposure while performing the following duties:
- Repairing boilers, condensers, and furnaces
- Installing, removing, or replacing gaskets and seals
- Cutting, disconnecting, or removing electrical wiring
- Installing or replacing motors, compressors, sensors, and thermostats
Asbestos in Ductwork
HVAC technicians can experience significant asbestos exposure in ducts when working on older HVAC systems. Metal ductwork was often lined with asbestos paper as insulation. Workers applied asbestos paper to ductwork while wet to conform to the ductwork and form a tight seal. Wetting the asbestos can inhibit it from becoming airborne, but once dry, it can easily become airborne if touched or cut. Workers who cut paper-lined ductwork while repairing, removing, or installing ductwork may have been exposed.
In some older houses, ductwork was made of asbestos cement. Cutting, removing, sanding, or drilling into asbestos cement can release significant concentrations of asbestos fibers into the air, causing significant asbestos exposure.
Duct tape held ductwork together, and it contained asbestos. HVAC technicians may have been exposed to asbestos in duct tape while cutting, applying, or removing it.
Asbestos is an effective soundproofing material. Air handlers can cause loud noises from the vibration that occurs when air travels through ductwork. Thus, the HVAC industry used asbestos in vibration dampers between metal ductwork and air handlers. HVAC technicians were exposed while installing, removing, or repairing them.
Asbestos in Building Construction
HVAC technicians may also encounter asbestos outside of the HVAC system in the following building components while cutting into walls, ceilings, and floors to install vents, ductwork, and electrical components:
- Asbestos floor tiles and underlayment
- Asphalt roof shingles and roofing felt
- Drywall, drywall tape, and joint compound
- Paint
- Wall or ceiling insulation
- Popcorn ceilings
- Adhesives

Legal Options for HVAC Technicians Diagnosed With Mesothelioma
The companies that mined, manufactured, and sold asbestos and the products made with it knew asbestos was harmful but continued selling the products without informing workers of the danger. Many of the asbestos product manufacturers knowingly concealed the truth about asbestos for decades. You may be entitled to compensation through multiple avenues if you or your loved one has developed mesothelioma as a result of asbestos exposure while working as an HVAC technician.
Wrongful Death Lawsuits
If your loved one has died from mesothelioma caused by asbestos exposure while working as an HVAC technician, you may be entitled to economic, non-economic, and punitive damages through a mesothelioma wrongful death lawsuit. These damages may include the following, depending on the laws of your state:
- Loss of your loved one’s income
- Funeral and burial expenses
- Your loved one’s medical expenses
- Loss of companionship
- Loss of love and affection
- Loss of parental guidance
- Emotional distress
Asbestos Trust Funds
By the time the general public learned what the asbestos industry knew all along about the dangers of asbestos, millions of people were suffering from deadly asbestos-related illnesses, including mesothelioma, lung cancer, and asbestosis. Many asbestos product manufacturers declared bankruptcy in response to the many lawsuits against them. Bankruptcy laws required these companies to establish asbestos trust funds to compensate asbestos-exposure victims.
If the companies responsible for your asbestos exposure filed for bankruptcy, you may be entitled to file a claim with the asbestos trust funds for your medical expenses, lost wages, and pain and suffering. Our experienced mesothelioma lawyers can determine whether you qualify and help you file your trust fund claims. You may be able to receive compensation within 90 days of filing your trust fund claim.
VA Compensation
If you were exposed to asbestos while working as an HVAC technician in the military, you may be entitled to VA disability benefits. VA benefits for mesothelioma include free medical care and monthly disability compensation.
