The photo was taken a few days ago by one of our professional team members.
Owner is shocked when the technician presents him this photo. Even though the evaporative cooling system is currently working, he said he would never think the cooler unit can be such disgusting inside. Dust and dirt accumulated everywhere, include the ducts, return air ducts and the unit, and the system is keeping blowing the air through the dirty system into every corner of his house via the air ducts, and ultimately into your lungs.
Don’t delay the service to your heating and cooling system and the ducts, even if they are currently working “fine”, the dust and germ growing inside of the unit and ducts are affecting your health and also keep damaging your heating and cooling system. Act now before paying extra for fixing or replacing the system, also for your own family’s good.
