The importance of air duct cleaning
Air duct cleaning has a lot of health and financial benefits to the homeowners. Dust and other debris that build up in the heating and cooling system encourage mold and bacteria growth if moisture gets in the system. This leads to health issues such as allergic reactions. Unclean air duct systems are less efficient and usually break down frequently unlike the sanitary systems which require less energy to operate hence reducing the cost of energy. The air duct cleaning process is simple; here is a brief guide how Air Tight Heating & Cooling Systems performs most air duct cleanings:
- Preparation: Before coming into the home, our HVAC technicians wear protective booties to protect the home’s floor. We also cover floors in the main walkways and any areas we might be working in, to further protect the home. Once in the home, the hvac technitian(s) inspect air ducts with a high definition camera to give the homeowner a visual of the inside of the air ducts, and ensure that the air ducts are in good working order for the air duct cleaning. We also inspect the air duct vents for any gaps between the vent and drywall. If necessary, the air duct vents are sealed to minimize any air loss into and out of the home.
- Cleaning: In some cases, a small hole is drilled into the return or supply plenum and vaccum brush is used to push through the ducts and disengage any remaining debris. Some objects can find their way into an air duct; this causes a blockage which affects the productivity of the systems cooling and heating. A scoping camera is used to find any blockages so that it can be removed. If the blockage is severe, the duct may need to be disassembled for removal.
- Finishing: After cleaning the ducts, and any blockages have been removed the vacuum is disconnected from the return or supply plenum and the plastic bags are taken off the vents. The duct cleaning process is completed with any holes that were made being carefully plugged to keep them airtight. Any ducts that were taken apart to clear blockages are put back together, and the hole in the furnace trunk is patched up with a large metal plate.
