Why is suction power and negative pressure necessary?

Without sufficient suction power, the HVAC system cleaning company cleaning your house or building can’t get your system clean. In the parlance of the industry this is called capture velocity. If they don’t have sufficient suction power there is a substantial chance of cross contamination. When your house is cross contaminated filthy debris won’t be totally removed from the part of the system being cleaned and portions can end up in other parts of the system or inside your home or building.

There needs to be enough negative pressure so that when dislodged it will be removed from your system and not enter your house or building. There is a large percentage of HVAC cleaning companies that don’t meet NADCA’s minimum standards.

For those companies that passed the NADCA certification test, and know what capture velocities are required to get your system cleaned, why doesn’t their equipment meet even minimum NADCA standards? How can they protect you against cross contamination with the underpowered equipment they use?

Don’t waste your money. Make certain the company you use exceeds 4,500 cubic feet per minute escape velocity. Monster Vac’s Trucks idle at 21,000 cubic feet per minute.(Back to top of page)

Poor indoor air quality can cause
or contribute to the development
of chronic respiratory diseases such
as asthma and hypersensitivity
pneumonitis. People who already have respiratory diseases are at greater risk.
