According to the US Department of Energy, 25-40% of the energy used for heating or cooling is wasted. In a situation where filters are built into a system, even during normal use, the heating and cooling system continues to clog. The contaminants present in the heating-ventilation-air conditioning system slow down the passage of air. The fans must then provide more effort and the life of the system is thus reduced.

On the contrary, when a heating-ventilation-air conditioning system is well maintained, it requires less energy to perform the same tasks. Therefore, if you use less energy, you increase the profitability of your business. Additionally, systems that are clean and perform better are less likely to fail, last longer, and are generally more efficient than dirty systems.

Research conducted by the U.S. Environmental Protection Agency (EPA) has shown that removing contaminants from the sensitive mechanical components of an HVAC system can allow them to operate more efficiently and consistently, at lower cost. .

NADCA members have signed a code of ethics stating that they will do their best to protect the consumer while following their association’s standards for cleaning HVAC systems to the best of their ability.

Air duct cleaning companies must meet very strict requirements to become a member of NADCA. Among these requirements, all NADCA members must be certified as Air System Cleaning Specialists (ASNS) after passing the certification exam. Passing the exam demonstrates in-depth knowledge of HVAC system design and cleaning methods.

Air system cleaning specialists are also required to continue their training by attending seminars to maintain their NADCA certification. You can view the NADCA Code of Ethics here. (link to the code of ethics page)

  1. Approach as many local entrepreneurs as possible.
  2. Invite them to come visit your home to inspect your system and present you with an offer of services. In order to narrow down the number of potential contractors, you can use the following criteria:
    has. ensure that the contractor is a member in good standing of the National Air Duct Cleaners Association (NADCA) and is certified by it to perform HVAC system cleanings;
    b. check if the company has been in business long enough to have acquired all the necessary experience;
    vs. ask for proof that the contractor is duly authorized and that he is sufficiently insured;
    d. make sure that the company will visually inspect and clean all the air ducts and all other components connected to the system;
    e. avoid ads such as “Special $119.99 for the whole house” and high-profile advertisements;
    f. check to see if the company has the proper equipment to do the cleaning effectively and if the contractor has done work on homes similar to yours. Ask for referrals from neighbors if possible.

Cleaning a heating-ventilation-air conditioning (HVAC) system can help prevent and solve several health problems:

  • Allergies or asthma
  • Colds, rhinitis, bronchitis, sinusitis, recurrent flu
  • Eye, nose and skin irritation
