Traditional duct cleaning methods like vacuuming and HEPA filtration can do an effective job of removing contaminants from HVAC ducts.


Traditional duct cleaning methods like vacuuming and HEPA filtration can do an effective job of removing contaminants from HVAC ducts. However, over time dust, allergens and microbes will inevitably make their way back into ducts. Consequently, interior duct coating presents an innovative solution for duct cleaning in Ottawa that helps keep contaminants from readhering to duct surfaces.

How Duct Coating Works

Interior duct coating involves applying a thin layer of protective coating to the inside surfaces of air ducts. The coating material is specifically designed to create a barrier that makes it difficult for particles and microbes to adhere. Consequently, when air flows through coated ducts, contaminants tend to remain suspended in the air stream and pass through the system.

Typically, duct products consist of either acrylic or epoxy resin bases that are sprayed or brushed onto duct interiors. The coatings cure to form a smooth, mostly impermeable liner that resists contamination.

Benefits of Interior Duct Coating

Some key benefits of applying interior duct coating as part of duct cleaning in Ottawa include:

  • It helps trap contaminants. The slippery coating makes it hard for dust, pollen and microbes to adhere, encouraging more particles to be captured by filters.
  • Ducts stay cleaner longer. Since contaminants do not readily collect on coated duct surfaces, cleaned ducts tend to remain cleaner for longer.
  • Fewer contaminants recirculate. Less dust and microbes sticking to ducts means less re-entrainment and recirculation of contaminants back into the airstream.
  • Improved indoor air quality. When ducts stay cleaner for longer, less contaminants are released into rooms, leading to better indoor air.

In summary, applying an interior duct coating as part of a thorough duct cleaning process in Ottawa can help keep ducts cleaner for longer by creating a barrier that discourages contamination buildup. The advantages include less recirculation of contaminants, improved indoor air quality and potentially reduced cleaning costs over time. Therefore, incorporating duct into a duct cleaning strategy can provide longer-lasting results compared to traditional methods alone.
