The quality of the air we breathe indoors has become an increasingly important environmental concern. Studies have shown that two out of three indoor air quality problems involve the HVAC system. Dust, dirt, smoke, allergens, animal dander and 
other contaminants circulate throughout every room of your home each time your furnace or air conditioner runs. Over time, these particulates can build up in your duct system and may become a breeding ground for mold spores, bacteria, mildew and other microbes.
How do you know if it’s time to have an air duct cleaning?
There are several indicators that will help you determine the best time to have your duct system cleared and sanitized. Follow this simple checklist:
- Air ducts should be cleaned every three to five years. If it’s been longer, it’s time.
- Rapid accumulation of dust shortly after you clean doesn’t necessarily mean you’re bad at housekeeping – it may indicate a dirty air duct system.
- Notice an increase in allergies or respiratory problems? Duct cleaning decreases pet dander and other contaminants that may float around your home and cause reactions.
- Construction and remodeling also create more dirt and debris, so make air duct cleaning your final step in any construction project.
- If you live near an unpaved road, it’s recommended to have air ducts cleaned every two-and-a-half to three years.
- If you’ve purchased a home and don’t know its air duct cleaning history, consider cleaning. Odds are, they haven’t been touched in years.
Proper air duct cleaning can not only lead to better air quality, it will increase the efficiency of most furnaces and reduce your energy costs. Remember, make sure the company you choose cleans your entire duct system – not just the openings you can see.
