When done correctly, HVAC cleaning is a very beneficial service for your home or business. NADCA’s dedication to quality assurance helps ensure and promote a higher standard of performance for all of its members.
A company must meet strict requirements in order to be a member of NADCA. The company must:
have at least one NADCA certified Air Systems Cleaning Specialist (ASCS) on staff
maintain general liability insurance
agree to clean according to ACR, the NADCA Standards and comply with NADCA's Code of Ethics. If a company is not going to clean according to NADCA's standards, this must be communicated to the buyer at the time of sale.
These requirements were established to provide a higher level of assurance to consumers.
Finding a Qualified Contractor
When speaking to a contractor, make sure they can show proof of NADCA membership and certification.
Make sure the contractor will conduct a thorough inspection of your HVAC system and alert you to any problems.
Make sure the contractor will clean all of the HVAC system components including, at a minimum: air ducts, coils, drain, registers, grills, air plenum, blower motor and assembly, heat exchanger, air filter and air cleaner.
