Duct Cleaning Equipment: What to Buy
When it comes to duct cleaning equipment, size matters.
While portable cleaning systems cost less and are convenient, they lack the suction power to clean out dust and debris that gets trapped in residential duct work. On average, a portable system uses a small compressor to move 250 cubic feet of air per minute (CFM).
Larger duct cleaning systems mounted in trailers or vans usually rely on low horsepower engine compressors and generate more suction; usually 400 - 1,000 CFM. While that's an improvement over a portable system and might perform adequately for smaller homes, they are too underpowered for the average residential system.
Truck-mounted systems are best suited for most residential as well as commercial duct cleaning. These systems are powered by the truck's engine and develop up to 16,000 CFM. That kind of air flow provides A LOT of suction. You remove dust, dirt, and debris from the toughest residential duct systems. Truck mounted systems are also equipped with larger vacuum bags to capture all that dust. The bags fill the back of the truck. On some powerful units, the ceiling is retracted to allow the vacuum bags to expand above the roof.
Truck mounted cleaning systems are clearly superior to the other two options. The sheer power produces greater cleaning pressures that work consistently throughout the cleaning process. The result is an improved and more thorough cleaning that reduces harmful airborne contaminants and increases ventilation efficiency.
To keep your home energy efficient and reduce your energy costs, get your ducts professionally cleaned every 3 to 5 years.
