How Often Should You Have Your Air Vents Cleaned & How Often You Should Change Your Furnace Filters


The frequency of air vent cleaning depends on several factors such as the size of the home, the number of occupants, the presence of pets, and the level of air pollution in the surrounding area. As a general guideline, it is recommended to have your air vents cleaned every 3 to 5 years. However, you may need to clean them more frequently if:

  1. You have pets: Pet hair, dander, and other debris can accumulate in your air ducts, leading to poor indoor air quality.

  2. You or your family members suffer from allergies or respiratory issues: If you or your family members suffer from allergies or respiratory issues, cleaning the air ducts can help reduce the amount of allergens and irritants in the air.

  3. You notice dust and debris coming out of the vents: If you notice dust, debris, or other particles coming out of your air vents, it may be time to have them cleaned.

  4. You have recently renovated or remodeled your home: Renovations and remodeling projects can generate a lot of dust and debris, which can clog your air ducts.

It is important to note that air duct cleaning is not a one-size-fits-all solution and should be done on a case-by-case basis. Consult with a professional HVAC technician to determine if and when your air vents should be cleaned.


Now what about your furnace filters?


The frequency of changing furnace filters depends on several factors, including the type of filter you have, the level of air pollution in your area, and the frequency of use of your HVAC system. As a general guideline, it is recommended to change furnace filters every 1 to 3 months. However, some filters may last up to 6 months or even a year.

Here are some factors to consider when determining the frequency of filter changes:

  1. Type of filter: Different types of filters have different lifespans. Disposable fiberglass filters are the most basic and typically need to be changed every month. Pleated filters, electrostatic filters, and HEPA filters can last longer, from 2 to 6 months or more.

  2. Level of air pollution: If you live in an area with high levels of air pollution or have pets, you may need to change your furnace filter more frequently to maintain good indoor air quality.

  3. Frequency of use: If you use your HVAC system frequently, you may need to change the filter more often.

  4. Allergies or respiratory issues: If you or someone in your household has allergies or respiratory issues, you may need to change the filter more frequently to reduce the amount of allergens and irritants in the air.

It is important to check your furnace filter regularly and replace it when it appears dirty or clogged. A dirty filter can reduce the efficiency of your HVAC system and lead to higher energy bills. Consult your HVAC system manual or a professional technician to determine the recommended frequency of filter changes for your specific system.
