We Raise The Bar on Clean

Why Air Duct Cleaning Matters.

Duct Cleaning is an important service to ensure your home and family are cared for. Benefits include…

  • Healthier indoor air environment.
  • Energy Savings with a more efficient system.
  • Increase the performance and longevity of your furnace.
  • Reduce odors, smells, and allergens that could lead to respiratory issues.

Did you know, an average of 40 lbs of dust can accumulate annually. Allergens and contaminants in your system are recirculated 5-7 times each day. Additionally, buildup in your ductwork is a fertile condition for bacterial growth.

Because of this, it’s so important to keep your air ducts clean and regularly maintained to ensure your environment is a healthy one for you and your family. In addition to the health risks that come with not cleaning your air ducts, the Department of Energy estimates a 25-40% loss of cooling and heating energy is wasted each year.

Core Value Co’s technicians are experienced and trained in the latest procedures and use the most effective cleaning tools. The methods and equipment we stand behind are catered to meet the specific needs of your home or business.

Duct Cleaning Preparation (PREP)

Core Value Technicians, use a systematic approach for Air Duct Cleaning, ensuring every customer receives equally excellent service.

  1. Protect the floor from your entryway to furnace with clean drop cloths. In addition, we use corner guards to protect doorways and corners.
  2. Route our 8-inch vacuum hose to your furnace along the drop cloths and compressed air lines to the first point of cleaning.
  3. Establish collection points into the main trunk-lines, where we insert our vacuum hose. While near the furnace, we’ll prevent dirt from making its way into the furnace cavity with barriers.
  4. Produce a negative air pressure by covering all supply registers and return grills. This also prevents dirt and debris from escaping into the living space.

Our Duct Cleaning Process


Our duct cleaning truck produces more than 12,000 cubic feet per minute of vacuum force (a contractor grade Shop Vac is under 200 cfm). To achieve the greatest quality, we use negative pressure, agitation “whips” or brushes and compressed air. This is in compliance with National Air Duct Cleaners Association standards.

When negative pressure created through a system, the primary force of suction is focused at each point we have opened. We use various agitation tools to break loose build-up and compressed air to push it towards a collection point. This ensures every inch of the duct is cleaned. If any flex duct is found, we only use compressed air to not damage the airway.

Return Air Ducts

This is the starting point of our process and follows the flow of air through any system. Most cleaning companies do not clean the return ducts. We understand the principle of circulation; put simply, the return air will become the supply air.


Included in our cleaning is air washing the furnace blower motor, furnace filter compartment and hand cleaning the exterior.


Each branch and register of the supply will be cleaned using agitation and compressed air.

Main Trunk Lines

Once we’ve pushed all the debris to the main lines. We continue the same process of agitation and forced air all the way to the 8” vacuum hose, removing all contaminants from your system.

Hand Cleaning

Each register and boot are hand washed with an all-natural cleaning agent before reinstalling it.
