Ten Maintenance Suggestions For Your Air Vents

Submitted by: Walter Thomas

Maintaining clean air ducts can contribute to cleaner air in your family’s home. Regardless of whether you get your air vents professionally cleaned, a regular maintenance plan can help cut down contamination of your air ducts. Duct preventative cleaning revolves around two components, limiting the volume of foreign particles (insects, pollen, rodent droppings, insect droppings, dust, pet dander) that goes into your air ducts, heating and cooling system and prohibiting moisture from entering your air vents.

Tips to limit the volume of foreign particles in your system:

1.Use the highest efficiency air filter you can afford as recommended by the manufacturer of your HVAC.

2.Change air filters regularly. How often varies based on on where your house is, whether you have a pet, if anybody smokes in your house and how how much your system is used.

3.Be certain all filters are in place (various heating and cooling systems use multiple filters) and that they fit properly such that air is prevented from getting around the air filters.

4.If you get your HVAC serviced, have the service technician clean the coils and drain pans.

5.Refrain from operating your HVAC system and block the return and supply vents during significant home renovations that will generate a considerable amount of dust.

6.Dust and vacuum your home regularly. Ideally use a high efficiency (HEPA) vacuum and the highest efficiency filter you can afford.

Moisture in air ducts is never a good thing. It can bring about mold, bacteria and fungi growth which may create health problems. Moisture in ductwork is not all that uncommon and can be caused by HVAC or by other elements such as leaks in pipes or a leaky roof. Research indicates that condensation on or near cooling coils in air conditioners is a considerable contributor of moisture in air ducts. Condensation is standard and is caused when the temperature of air in the HVAC system is below the dew point temperature of surrounding air. Newer HVAC, when operating properly, are meant to remove this condensation without any contamination of the airducts. Improperly installed heating and cooling systems, improperly serviced systems and malfunctioning systems make it more likely that condensation will do damage to the system.

Suggestions to prevent moisture from getting into your system:

1.Repair all water leaks and water damage swiftly and diligently.

2.Condensation coils, when functioning correctly, remove moisture from the air and drain pans extract the water from the HVAC. Both cooling coils and drain pan should be inspected routinely. Drain pans should drain completely so standing water in the pan can means the pan is not operating correctly. The drain pan should be free of debris that may impact its ability to drain adequately.

3.Airducts should be sealed and insulated whenever they are in areas that are not cooled such as attics, crawl spaces or garages. This will help reduce condensation by reducing the temperature difference between the air within the ducts and the air directly adjacent to the ductwork.

4.When replacing an air conditioner be sure the new unit is suited for your size house. An air conditioner that is too big will tend to cycle on and off more frequently which diminishes its ability to remove moisture from the air.

Waiting to get your air ducts cleaned until there is an issue such as presence of mold frequently means your family has already been exposed to the health hazard. For this reason regular upkeep of your airducts is critical, whether by a professional air duct cleaner or by preventative maintenance taken by the homeowner.
