Asbestos Furnace & Duct Cleaning FAQ

Asbestos is a toxic mineral and was used in building materials from the 1950’s to the 1970’s. If your home was constructed during that time, it is possible that asbestos has been used in insulation or in insulative tape (as seen below). If your ductwork has white tape on it, it is almost guaranteed to contain asbestos.

If your system contains asbestos tape, we are now able to safely clean your furnace in most cases without requiring prior removal.

While our cleaning equipment does put pressure on your heating system, we have implemented a specialized safety process to protect your home. Our technicians now utilize a professional-grade “lockdown” sealant (Fiberset PM) that encapsulates the tape. This creates a flexible barrier that prevents microscopic fibers from becoming airborne during the cleaning process.

This procedure allows us to maintain strict health and safety standards for you and our technicians while ensuring your cleaning is completed without delay.

Asbestos containing products that have not been distrubed and are still in good condition are not a direct health hazard. These products become a potential health hazard when they are disturbed and fibres are released. 

First of all, don’t panic. Asbestos becomes dangerous when it is friable (easily crumbles and releases fibers) and disturbed.

Previously, the presence of asbestos tape meant we could not proceed with furnace and duct cleaning. However, we have updated our safety protocols to help you. We now utilize a specialized “lockdown” sealant called Fiberset PM. This professional-grade coating encapsulates the tape, creating a flexible barrier that locks in microscopic fibers and prevents them from becoming airborne.

This process allows our technicians to safely clean your system without disturbing the asbestos. While we do not perform full asbestos removal (abatement), this safety measure means we can complete your cleaning in most cases without requiring you to hire outside professionals first. If the material is too severely damaged, we will still refer you to abatement specialists, but for the majority of homes, we can now get the job done safely and immediately.
