   The negative air method is the best method of air duct cleaning. This means a separate vacuum is used to create negative air pressure throughout the entire duct system. In other words all the vents should be sucking air back to the negative air vacuum. The hose that is creating this situation is at least 8 inches or better 12 inches in diameter. If the vacuum hose fits in the register then they are not using negative air. Now once the vacuum is running the tech will choose the best tools to dislodge the dirt from the duct-work and push it back to the vacuum.
   Now with negative air there are 2 types of system - Portable and truck mount. Success can be achieved with either if done correctly. I prefer portable for the following reason. Portable equipment returns clean air back into the home so the home does not need to replenish the air from another source. With truck mount equipment any air removed from the structure will be replaced naturally. This is done because as air is pulled out fresh air is sucked in through any cracks crevices open windows etc. With a truck mount outside air is pulled into the home through voids in the structure bringing any contaminants in those voids along for the ride.
   I also like portable equipment because temperature in the home remains stable. With truck mount equipment since outside air is pulled in, the home quickly becomes the same temp and humidity as outside then it cost the homeowner money to heat or cool it back normal when the job is finished.

   There are a few techniques to clean ductwork in homes. You should be careful to make certain that the duct cleaner informs you of their methods prior to commencing work. Some are more efficient than others. Do not be fooled by low prices. The most informed and professional duct cleaners are also members in good standing of NADCA the HVAC Inspection Maintenance and Restoration Association.
