HVAC Duct & System Cleaning
Cleaning of an HVAC system is one of the best ways to improve indoor air quality and system performance. Our services will deliver a cleaner and more comfortable environment.
Our “source removal” method of cleaning removes dirt, dust, lint, mold, mildew, fungi or bacteria that are possibly being dispersed in to the areas you are occupying daily, and will produce a cleaner and more comfortable environment in your home or business.
Why it’s cleaned
According to the Environmental Protection Agency, Indoor pollutant levels may be 10 to 100 times higher than outdoor concentrations. These indoor pollutants come from a variety of sources, including occupants, pets, furniture, home cleaning activities and outdoor air. HVAC systems can distribute these pollutants and are a perfect breeding ground for biological contaminants, including mold, but cleaning your system will remove these contaminants before they enter the air you breath. A clean HVAC system may also perform at a greater level of efficiency and require less energy to function properly, which can lead to improved environmental comfort control, longer equipment life and reduced electricity costs.

Should You Have Your HVAC System Cleaned?
A system needs to be cleaned when a significant amount of debris or microbial growth is observed, the system discharges visible particulates or equipment is determined to have blockages that may cause performance to suffer. Guardian performs free, photo documented, inspections for all customers and has certified air system cleaning specialists on staff to help you determine if you or your system can benefit from cleaning. The National Air Duct Cleaning Association has created a guide and checklist for customers considering cleaning their systems.
Our Cleaning Process
Guardian uses the National Air Duct Cleaning Association's prescribed cleaning techniques to perform a total HVAC system clean. This includes using “source removal” methods to manually clean the air conditioning unit housing (indoor and outdoor), all ductwork, fans, coils, drip pans, grills and diffusers. This is the only method which ensures the entire system is clean and will not be re-contaminated immediately following cleaning. Guardian's cleaning process begins with a system assessment to determine the best cleaning methods to use in order to protect the building occupants and equipment. Protective plastic sheeting is used to cover all vulnerable surfaces and HEPA filtered negative air vacuum collection devices are connected to the system to prevent contaminants from entering occupied spaces. Our technicians access the system in a professional manner and use agitation devices, such as air whips and brushes, to remove contaminants and HEPA-filtered vacuums to collect these contaminants. Once the system is entirely clean, and with the owner's approval, the system is treated with a deodorizer to help eliminate odors and biological contaminants. All access points are re-sealed, per code, the system's performance is checked and our technicians remove all the plastic and clean up all areas serviced.
