Read MoreMini Split units or PTAC units are wall or ceiling mounted heating and cooling systems that allow you to control the temperature in individual rooms. They have little to no ducts but still require routine cleaning.
A mini split/PTAC unit should be on a regular maintenance schedule like most home appliances. These units should be cleaned annually as mold builds up quickly and is very prevalent due to the excessive moisture, porous material and food source available.







First, the technician will remove the filter and outside covering.
Next, the technician will set up a split unit cleaning device to catch all contaminants and water released during the cleaning process.
The technician will hand-vacuum off the coils found in the split unit.
Then, the technician will chemically treat the coils, fan blades and blower wheel to break down and loosen mold and containments.
The coils, fan blades and blower wheel are wet washed with water to remove contaminants.
Following, an antimicrobial treatment is applied to the coils, fan blades and blower wheel to help prevent mold build up.
Finally, the technician will clean and treat fitler with an antimicrobial followed by the reinstallation of the unit.
Michael BennettWe had such a great experience with NJ-Advanced-Air Duct! Their technicians arrived right on time, wore shoe covers, and treated our home with so much respect. They explained everything they were doing and showed us before-and-after photos of the vents. The air in our home feels so much fresher now, and we’ll definitely be booking them again next year!

As a general rule, for every dollar spent on preventative maintenance, you will save at least five dollars in subsequent expenses. Studies by General Motors and 3M both state that spending one dollar on preventative maintenance could save you anywhere from 7-35 dollars including but not limited to: lost production, added inventory, labor, parts duplication and equipment redundancy.
“An ounce of prevention is worth a pound of cure” Benjamin Franklin
