HVAC systems are known to collect mold, fungi, bacteria, dust particles and other contaminants. Cleaning your HVAC system removes these contaminants and improves your indoor air quality. Frequency of cleaning depends on several factors, not the least of which is the preference of the homeowner. Consider more frequent cleaning for:

  • Allergy or asthma sufferers
  • Smokers in the household
  • Pets that shed high amounts of hair and dander
  • Water contamination or other damage to the home or HVAC system
  • Recent home renovations or remodeling
  • Prior to occupancy of a new home

In your home or business, you are surrounded by dust. It collects on your furnishings, on drapes and window treatments, in your carpets and worst of all, in your Heating Ventilation and Air Conditioning (HVAC) system. Over time normal accumulations of dust, dirt, and debris can build in the ductwork of your system allowing these contaminants to then be distributed throughout your home or business. This can cause unsafe air quality that can lead to unhealthy conditions. Regular maintenance such as simply changing the air filter can help to reduce the air quality issues, however a regular cleaning is still needed to remove contaminants from the system and ductwork.

As a certified member of the National Air Duct Cleaners Association (NADCA) Cunningham Duct Cleaning Co. follows a high standard in order to meet stringent requirements set by NADCA. Typically our Truck Mounted Vacuums are used to clean your HVAC system–during cleaning, the entire HVAC system is connected to our truck and placed under continuous negative pressure to prevent the spread of contaminants. This allows the system and ductwork to be brushed and cleaned removing particles as they become airborne. This process delivers a clean passage of particles from your ductwork directly out to our truck without contaminating your home. See Residential Air Duct Cleaning.

Commercial services are usually provided through a process known as “contact cleaning”. This process employs a Truck Mounted Vacuum or a portable HEPA vacuum to provide negative pressure in the HVAC system, as cleaning is taking place. Contact cleaning is done by creating service openings as required to physically vacuum all surfaces of the ductwork. At the completion of our services all openings will be closed as per industry standards, providing an air tight enclosure. See Commercial Air Duct Cleaning.
