Cleaning main duct access
The main air duct proves to be the place with the most dirt buildup, and cleaning it will help keep your air filter and smaller air ducts clean. You will need to remove the end caps from the duct work to gain access. Once you have access to the main duct, take your vacuum hose and vacuum out the main duct and the end caps. In a basement, the duct work will contain registers that need removed as well. Ensure that you have replaced all parts and they are secure and in the proper place when finished.
Reducing dust and moisture
To reduce dust in your ventilation systems, use a high - efficiency air filter, change the filters on a regular basis, check for clogs, and ensure you have an adequate amount of filters to use. When a technician services your heater or air conditioning unit, ask the technician to clean the cooling coils and be sure to drain the pans. Keep dust to a minimum when renovating or remodeling your home. Cover the vents with plastic before beginning. Dusting and vacuuming on a regular basis, and cleaning air vents will help with this process. Prevent the air ducts from getting wet as moisture could add to the growth of mildew and mold. Repair any leaks or water damage.
The cooling coils are designed to remove the water from the air and can be a source of moisture contamination. This extra moisture will contribute to mold growth, and the pan needs to be able to drain properly to avoid mold build – up. The ducts need to be properly sealed and insulated in all attics and crawl spaces to prevent extra moisture from entering the ventilation system.
Extra dust will make your system work harder and can cost more money. A buildup of these dust particles, moisture, varmints, and pollen can weaken your air conditioning and heating system. This can eventually add extra wear and tear on your air vents. Moisture causes mold spores which can be released into your home and can cause allergic reactions and respiratory illnesses. It is suggested to apply chemical biocides to kill the mold inside of the ductwork and ensure your air is safe. There are benefits to cleaning your air ventilation system on a regular basis. Keeping them clean will help avoid musty smells as well.
