- Mechanical System EvaluationPrior to initiating any commercial cleaning activities, a DUCTZ professional or an independent Indoor Air Quality Consultant should determine the system cleanliness and economic practicality of undertaking restorative cleaning activities.This determination shall include a site survey of the building; a visual assessment of the HVAC system’s components; age of the components under consideration; and an economic assessment of HVAC system cleaning versus equipment/component replacement. Upon completion of the analysis, and in accordance with the clients’ needs, the criteria for level of cleanliness shall be established, documented and agreed upon by all involved parties. Visible contaminants within HVAC systems from rodent or insect infestation, storm or flood damage, water infiltration, fire and smoke damage, mold, construction or remodeling particulates, or general debris blowing out of supply registers or grilles are conditions necessitating implementation of this standard.
- HVAC System Cleaning DUCTZ commercial cleaning and restoration processes involve more than 127 identifiable and distinct tasks. During the cleaning and restoration process, various assortments of highly specialized and proprietary tools, machinery and supplies are used. In addition, DUCTZ uses patented processes, such as an exclusive metallic barrier in the air plenum of the furnace and in certain ductwork. This barrier eliminates fiberglass shedding and prevents the fiberglass from acting like an absorbent sponge, which collects dirt and moisture, creating a breeding ground for microbial growth, bacteria and fungi.
- Fire & Water Damage HVAC interior surfaces have the potential to collect particulate, smoke, moisture, gaseous emissions and other contaminants as the result of a fire or smoke event. This can occur even while the HVAC system is in a de-energized (non-operational) state. Deposition of these foreign materials may alter the HVAC system’s components, potentially affecting system performance, corrosion resistance, and the general hygiene of the HVAC interior surfaces. A standardized evaluation of the HVAC interior surface conditions is necessary to determine when HVAC interior surfaces have been impacted by a fire-related particulate.When addressing water related issues within mechanical systems DUCTZ strictly adheres to the institute of Inspection Cleaning and Restoration Certification (IICRC) S500 and S520 standards to assess and restore mechanical systems.
- Biological Growth DUCTZ processes control biological organisms, such as microbial growth and bacteria that form on cooling coils and other working parts of HVAC systems by mechanically removing the sources for growth. These organisms can interfere with the heat transfer process, causing reduced HVAC system efficiency. The DUCTZ microbial control cleaning process prevents corrosion often caused by sulfuric acid secreted by common bacteria. This process also prevents rust and corrosion, which can degrade the HVAC system forcing costly repairs and replacements. Our microbial control cleaning process also extends the useful life of HVAC systems while increasing overall energy efficiency by keeping fins, blowers and coils clean and running at peak operational performance.Indoor air quality can be adversely affected by the spread of harmful contaminants through the HVAC system. Contaminants in the HVAC system can cause odors, damage surfaces and secrete toxic byproducts to living and working areas. DUCTZ microbial control cleaning process improves indoor air quality at the source – the HVAC system. DUCTZ professionals take the necessary steps to protect from exposure to contaminants dislodged during the commercial cleaning process by using HEPA filtration on cleaning equipment and adhere to NADCA and other appropriate guidelines and standards.DUCTZ professionals use thoroughly researched processes and procedures, combined with appropriate products for the following applications: flexible ducts fabricated of metal or plastic, unlined sheet metal ducts, air handlers, cooling coils, fan coil units, condensate drain pans, humidifiers, dehumidifiers, registers, grills, diffusers, fans, fan housings, transfer boxes, turning vane, return ducts, plenums and rooftop units.DUCTZ professionals are certified, qualified and trained in microbial control cleaning processes and strive to improve indoor air quality and increase the operating efficiency of HVAC systems.
