Are there any health benefits that come from HVAC system cleaning?
Heating, ventilation, and air conditioning (HVAC) systems have been shown to act as a collection source for a variety of contaminants that have the potential to affect health, such as mold, fungi, bacteria, and very small particles of dust. The removal of such contaminants from the HVAC system and home should be considered as one component in an overall plan to improve indoor air quality.
How often should residential HVAC systems be cleaned?
Frequency of cleaning depends on several factors, not the least of which is the preference of the home-owner. Some of the things that may lead a home-owner to consider more frequent cleaning include:
Smokers in the household.
Pets that shed high amounts of hair and dander.
Water contamination or damage to the home or HVAC system.
Residents with allergies or asthma who might benefit from a reduction in the amount of indoor air pollutants in the home's HVAC system.
After home renovations or remodeling.
Prior to occupancy of a new home.
What criteria should I use when selecting an HVAC system cleaner?
You should interview as many local contractors as possible. Ask them to come to your home and perform a system inspection and give you a quotation. To narrow down your pool of potential contractors, use the following pre-qualifications:
Make sure the company is a member in good standing of the National Air Duct Cleaners Association (NADCA).
See if the company has been in business long enough to have adequate experience.
Get proof that the company is properly licensed and adequately insured.
Verify that the company is certified by NADCA to perform HVAC system cleaning.
Make sure that the company is going to clean and visually inspect all the air ducts and related system components.
Avoid advertisements for "$99 whole house specials" and other sales gimmicks.
Ask if the company has the right equipment to effectively perform cleaning, and if the company has done work in homes similar to yours. Get references from neighbors if possible.
Why should I choose a NADCA member to have my air ducts cleaned?

Our source removal process begins by removing and cleaning all supply and return registers. Air handlers and all components of the HVAC system are cleaned (dampers, blowers, drain pans & coils).
Vacuum collection devices are used to place the HVAC system under high negative pressure throughout the cleaning process, to remove and contain all contaminants. Mechanical agitation devices (rotary brushes, high pressure air whip scrubbers, etc.) are used to dislodge debris adhered to interior HVAC system surfaces, and convey them to the vacuum collection devices. Proper care and specialized tools are used where duct liner is present, to thoroughly clean without damaging liner.
Existing service openings are used wherever possible. Additional openings needed to gain adequate access for cleaning will be created and closed in accordance with industry standards and codes. Proper containment procedures are used where necessary to prevent cross contamination. All visible contaminants will be removed. And all work will be done with minimal disruption.
ClearVent meets all certifications and safety requirements necessary. All work will comply with NADCA ACR

Why should I have my air ducts & HVAC system cleaned?
By ClearVent, Inc. May 14, 2014
First and foremost, an air duct and HVAC system should be cleaned for health and hygiene. Over time, air ducts and HVAC systems get dirty and like anything else in your home or workplace, it needs to be cleaned.
Second, a system should be cleaned for maintenance and energy efficiency. A clean system does not have to work as hard so it uses less energy to do the same job. A clean system lasts longer and has lower maintenance costs.
After an air duct and HVAC cleaning, many of our customers notice less dust in their homes, fewer odors and some allergy relief.
