When it comes to guaranteeing that a duct repair has been done correctly in Pembroke Pines, FL, duct testing is the most reliable way to go. This process involves sealing off the entire ventilation system and pressurizing it to determine how airtight it is. Professionals measure the amount of air pressure that is leaking from the ducts and then identify the areas that need to be sealed or repaired. DP tests can be conducted on-site during the roughing up of the duct network before the building is finished.
Final testing can also be done once the building is complete but before occupancy. This is especially useful if the duct system is located in an attic or small space and the duct testing equipment is installed within the main space. Two types of duct testing are available: pressure or leak testing (DP) and outdoor leak testing (LTO). During a pressure test, the flexible duct of the duct test fan is usually taped to the main return pipe without a filter.
This allows technicians to determine if the duct system meets current building code standards. Once duct testing is complete, experts will know precisely what needs to be fixed and how to handle those repairs. The most common type of duct test performed on new construction and existing homes is a total duct leak test, which measures all leaks in the duct system, both inside and outside of the conditioned space. When using a smoke emitter to fill a duct system, never use a duct inspection fan to extract smoke through the duct.
Instead, a fan door should be used to match the pressure of the interior space with that of the duct system while the duct tester fan is operating.
