Air duct cleaning companies offer a range of services beyond the traditional cleaning of air ducts. These services may include cleaning the dryer's ventilation grilles, installing an air purifier in the ducts, and restoring heating, ventilation, and air conditioning systems. Professional cleaning of the dryer ventilation grilles should be done annually to prevent clogs and potential home fires. Certified DUCTZ professionals follow all protocols established by the NADCA to clean air ducts.
The company's technicians are trained to efficiently and safely remove and clean all debris found in the air duct system, including system access points, fans, and coils. The company's thorough cleaning process includes the use of high-efficiency particulate air (HEPA) vacuums, negative atmospheric pressure, and sealing any holes with adhesive tape before turning the system back on. In addition to air duct cleaning, dryer vent cleaning should be done at least once a year. If signs of a rodent infestation are detected, an exterminator should be called before any further work can be done. Professional duct cleaning service providers may also offer sanitizing services to further preserve air quality.
The EPA does not recommend cleaning air ducts except when necessary due to continuing uncertainty about the benefits of duct cleaning in most circumstances. Cleaning and maintaining the oven or air conditioner itself will improve its efficiency and keep it running longer. If the air conditioner isn't cooling properly, the culprit is most likely a clogged filter than a dirty duct. The EPA recommends that the air duct system be cleaned only when really necessary or if the presence of mold is confirmed. In addition, there is no evidence that a small amount of household dust or other particulate matter in air ducts poses any health risk. Whether or not you decide to clean your home's air ducts, preventing water and dirt from entering the system is the most effective way to avoid contamination.
Once the cleaning is complete, clean and replace the boiler filters and other house filters, or talk to your technician about doing so to further preserve air quality. The resistance of sealants to deterioration over time has not yet been evaluated, which could add particulate matter to duct air.
