Your HVAC system may harbor many allergens, especially your air ducts. Moisture in the home can cause mold and mildew which can hide in the air ducts and spread throughout the home. Air ducts are also a great place for dust to build up and cause allergies. If you have pets, smoke cigarettes, or have a humid house your air ducts may need to be cleaned more often than other homes.
If you’ve had a home remodel where carpet and tile were disturbed you will definitely want to follow up with an air duct cleaning as the dust from a remodel will travel to the air ducts which may potentially make you ill.
If you do have allergies you will want to make sure to have your air ducts cleaned regularly to keep your family healthy. Simply having your air ducts cleaned can help to keep the need for medications down.
