Do not run the HVAC system if you know or suspect that it is contaminated with mold. If you suspect that it may be contaminated (it is part of an identified moisture problem, for instance, or there is mold growth near the intake to the system), consult EPA's guide Should You Have the Air Ducts in Your Home Cleaned?(4) before taking further action (see Resources List).
