Air duct cleaning can help improve your home’s air quality by removing dust, debris, bacteria, mold, and allergens from your heating and air conditioning system. However, many people don’t truly understand how professional duct cleaning is actually performed.
To begin, professionals first inspect your entire HVAC system to determine the best air duct cleaning method. This includes assessing vents, grills, ducts, returns, and other components. Furthermore, technicians determine if any repairs are needed before cleaning can commence.
Areas of the ducts that can be accessed are opened.
This commonly entails removing vent covers and wall access panels. In some cases, parts of the ductwork itself may need to be cut open to gain entry. Any compromised or damaged ducts are repaired or replaced at this stage.
Subsequently, the actual air duct cleaning process begins. Firstly, a special vacuum with a high-powered suction is utilized to remove as much debris and dust as possible from the ductwork. These vacuums are built specifically for air duct cleaning and contain massive filters to trap contaminants.
Secondly, specialized duct cleaning brushes may be inserted into ducts, plenums, and air handlers to physically dislodge additional debris. Rotating brush heads scrape particles loose from the interior surfaces of the ductwork. Then, the vacuum sucks up any remaining debris.
Moreover, powerful air jets are employed in some situations. Compressed air is forcibly injected into air ducts to literally blow contaminants loose. The rushing air also breaks up accumulated dust bunnies and clumps. Once again, a vacuum ultimately collects all particles.
Lastly, anti-microbial disinfecting treatments may be applied to clean duct surfaces. These sprays kill mold, bacteria, and other potentially harmful microbes harboring in your HVAC system. Some disinfectants also leave behind a protective coating to retard future mold growth.
Once the ducts have been thoroughly vacuumed, brushed, blown out, and disinfected, all vents and access panels are reinstalled. Finally, filters are replaced and the entire system is tested to verify proper air flow.
In conclusion, professional air duct cleaning involves a multi-step procedure utilizing multiple pieces of specialized equipment. Though somewhat intricate, the process effectively removes built-up dirt and contaminants from your HVAC system to enhance indoor air quality. Regular cleaning and proper filter usage can help keep your ducts clean between professional services.
