When is the last time you had your air ducts cleaned? If the answer is never or several years ago, your air ducts are probably filthy. Over time, dirt, debris, dust and allergens from outside enter your home or business through the doors and windows.
When your HVAC system activates, it pushes those particles through your ducts, where some of it collects. The rest of it becomes airborne where it can be inhaled and/or land on furniture and flat surfaces. This can result in the need to dust and clean your home or business more often, and it can lead to an increase in allergy symptoms and breathing difficulties in individuals with asthma or other chronic health problems.
There are 3 major parts to a residential air system that need to be cleaned and sanitized:
The supply and return grills.
The interior surfaces of the supply and return duct works; including all the main branches or main ducts coming out of the air unit.
The furnace/air conditioner air handler. This could be located on the roof, in the garage, the attic, or a closet.
All 3 components must be properly accessed and cleaned using the right procedures and equipment to ensure the best result. If only one or two of the components are cleaned, the contaminates from the 3rd component will rapidly contaminate the pieces that were cleaned. Be wary of companies who claim differently, they may be trying to give you a run for your money.
