hvacIt is the thorough cleaning of heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensation drain pans, fan motor and fan housing, and the air handling unit housing.

These components may become contaminated with particulate matter such as dust, dirt, smoke, pollen, or organic compounds if not properly maintained.

 If moisture is present, the potential for microbiological growth (ie: mold) is increased and spores from such growth may be released into the home’s living space. Some of these contaminants can cause allergic reactions or other symptoms in people when exposed to them.

It’s important for all components of the system to be cleaned. Failure to clean a component of a contaminated system can result in re-contamination of the entire system, thus negating the benefits.

Air Duct Cleaning Benefits:

Indoor Air Quality

Indoor air quality is a homeowners primary concern when deciding to have the air duct and HVAC system cleaned. Every day living in a six room house can annually generate several pounds of contaminants such as pet dander, allergens, dust and dust mites, debris, pathogens and chemicals. These contaminants are pulled into the HVAC system and re-circulated 5 to 7 times per day, on average. The re-circulation over time causes a build-up of contaminants in the Air Ducts and the HVAC system.

Dirty air ducts may be contributing to larger health issues or harboring contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders or some environmental allergies.

Energy Savings

Over 25% of your HVAC systems heating or cooling energy is wasted according to the U.S. Department of Energy. Contaminants in the heating and cooling system cause it to work harder and shorten the life of your system. Although filters are used, the heating and cooling system still gets dirty through normal use.

A clean air duct and HVAC system doesn’t have to work as hard to maintain the desired temperature resulting in less energy is used and leads to improved cost-effectiveness.

Air Duct Cleaning Process.

  1. Inspect and assess the Air Duct and HVAC system
  2. Discuss and document the work to be performed
  3. Perform cleaning and restoration procedures:
    1. Clean the supply and return registers and grills
    2. Clean the supply and return ducts
    3. Clean the Air Duct ventilation system
    4. Clean the HVAC system
  4. Cleanliness assessment
  5. Customer signoff

We use access tools to create entry points in the HVAC system to facilitate inspection and cleaning.  This allows tools such as the Predator and the AirSnake to move the debris to the vacuum collection device. The entry points are securely sealed upon completion.

We use several different cleaning tools including the Rotobrush system. The Rotobrush system works by inserting the 450 rpm rotating brush and combined vacuum hose inside the air duct to loosen the debris.  The vacuum intake port pulls the loosened debris into the High Efficiency Particulate Air bag leaving the air ducts debris free.

We use high powered vacuum collection devices to create negative pressure within the HVAC system, in order to remove the contaminants during the cleaning process. We use high powered air compressors with device attachments to clean other air duct and HVAC system components.

Additionally, we use the Flex-A-Lite fogging system to sanitize and disinfect. The Nok Out product we use eliminates biological and organic decay such as mold, mildew, bacteria, and fungi.

It does NOT contain chemicals harmful to the environment, and is fragrance free, biodegradable, non-toxic, non-corrosive, non-stating, non-masking and hypoallergenic. It is EPA registered and approved as an affective biocide, vericide and fungicide approved by the USDA for use in food processing areas.

Air Duct System Cleaning Schedule.

Many of our customers have the Air Duct and HVAC inspection and cleaning taking care of every 3 to 4 years. Our customers with pets or have low tolerance to allergens tend to have it done every two years. Home remodeling customers have an HVAC inspection and cleaning when the project is completed because air duct and HVAC components often collect a significant amount of debris and particulates during the construction activities.
