Conditions Requiring Cleaning
According to ACR, HVAC system cleaning must be performed when any of the following conditions are found in the cleanliness inspection:
→ Significant accumulations of contaminants or debris are visually observed within the HVAC system, and/or evidence of microbial growth is visually observed or confirmed by analytical methods.
→ The HVAC system discharges visible particulate into the occupied space, or a significant contribution of airborne particles from the HVAC system into the indoor ambient air is confirmed.
→ Heat exchange coils, cooling coils, air flow control devices, filtration devices, and air-handling equipment are determined to have restrictions, or contamination deposits that may cause system performance inefficiencies, air flow degradation, orthat may significantly affect the design intent of the HVAC system.

Our Cleaning Methodologies:
1) Vacuum Collection
2) Brushing
3) Compressed Air Washing
4) Hand or Contact Vacuuming
5) Hand Washing
6) Powerwashing

As a NADCA member we abide by the NADCA code of ethics:
NADCA Code Of Ethics:
→ We will serve our customers with integrity and competence.

→ We will perform our work using source removal methods. In order to eliminate or prevent the delivery of airborne pollutants into indoor air spaces through HVAC ductwork, we will remove the dust and others contaminants from the system. Thus, we pledge to administer source removal methods, cleaning the system ductwork as thoroughly as possible, before applying any coatings or treatments, including deodorizers, disinfectants, and/or sealants

→ We will be honest and forthright in our advertising.

→ We will provide our clients with accurate inspections and evaluations of the cleanliness and physical condition of their HVAC systems, using this information to determine the type of cleaning and maintenance services required, if any.
We will provide only necessary and desired services to our clients, and will not use furnace/air duct cleaning as a means of selling unnecessary or unwanted products or services.

→ We will provide services only after completing the necessary bonding and licensing procedures.

→ We will utilize the services and products of those who possess specialized skills, tools, or trades not possessed by us when circumstances call for work to be done which we are unable to perform.

→ We will require that all employees of our firm practice furnace/air duct cleaning in accordance with NADCA Guidelines and the Code of Ethics.

→ We will perform our services in accordance with the current published standards of the Association. If I will be unable to clean in accordance with NADCA standards, I agree to disclose this limitation to my customers at the point of sale, in advance of any cleaning.

The Ethics Committee shall hear and investigate charges of unethical conduct between concerned parties ,and will make recommendations to the Board of Directors concerning the resolution of those charges.


Guidelines For Selecting a Qualified Contractor
Asking prospective contractors the following questions will assist consumers of commercial HVAC system cleaning services in selecting a qualified contractor.
1. Can the company show proof of NADCA membership and certification? Please visit www.nadca.com.
2. How long has the contractor been in the commercial HVAC system cleaning business?
3. Can the contractor provide you with evidence of the current Worker’s Compensation and General Liability Insurance coverage? (Ask for Certificate of Insurance)
4. Does the contractor posses the proper licenses that are required by your city or state to perform the work they are proposing? (Not all cities or states require licenses – visit www.nadca.com to find out).
5. Can the contractor provide you with 3 to 5 customer references with phone numbers for projects of similar size and scope of work which they provided service in the last year?
6. Does the contractor have written safety, respiratory, and confined space programs in addition to OSHA compliance reports?
7. Will the contractor provide you with a means to conduct a visual inspection at any time during the cleaning? (Mirror and flashlight, camera or other remote visual systems)
8. Will the contracting company actually do the work? (Some companies subcontract the work to independent contractors. You will want to apply these guidelines for subcontractors as well.)
9. Will the company be assigning an Air Systems Cleaning Specialist (ASCS) to your project that will be responsible for the complete project?
10. If there is any remediation of mold or other biological contamination does the company have a Ventilation System Mold Remediator (VSMR) on staff.
