Air Duct Cleaning questions, answered by experts

Healthy air change per hour, or ACH, rates vary by room, usage, average occupancy, and volume. The minimum ACH that's considered healthy averaged throughout the home is 0.35. However, in rooms where humidity is an issue, such as bathrooms and kitchens, healthy ACH levels are between eight and 15.

Air ducts should be cleaned every three to five years, though the frequency can vary based on factors such as household conditions and local environmental factors. For homes with pets, smokers, or high dust levels, more frequent cleanings every two to three years would be necessary to maintain optimal air quality. If you notice persistent odors, significant dust buildup, or signs of mold or rodent activity, schedule a cleaning sooner.

How often you change the filters in your return air vents typically depends on factors such as your indoor air quality, the type of filter used, and the specific needs of your HVAC system. Generally, checking your filters every 1-3 months is recommended. However, if you have pets or allergies or live in an area with high dust levels, more frequent replacements may be necessary. Regular filter changes ensure that your HVAC system operates efficiently, maintains good indoor air quality, and extends its lifespan.

You should pick ozone treatment to remove smoke odors because it’s a high-tech fire treatment that removes odor molecules from the air in each room of your home. It’s better at getting rid of smoke smells than many sprays and air fresheners because it oxidizes the actual material that’s causing the odor rather than just covering up the smell.

The cost for air duct cleaning is about $380, on average. However, costs can range between $270 and $500, depending on location, number of vents, duct accessibility, and how much cleaning is required. Additional factors can impact the cost of cleaning your air ducts, such as removing pests, mold and mildew, asbestos, and other unforeseen needs. Any repairs will also add to the cost of the job.
