Air Duct Cleaning FAQs, answered by experts

If you have a fresh air intake as part of your HVAC system, the interior vents should be near your furnace or other gas appliances inside your home. From the outside of your property, your HVAC fresh air intake location is usually near the ground (although it may also be higher up, like on the roof or attic).

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

The best location for return air vents is strategic to ensure balanced airflow and temperature control. In most homes, placing them in central, open areas like hallways or large living spaces is most effective. Ideally, they should be located across from a supply vent. Climate is also a factor: in warm climates, place vents high on the walls to help remove rising hot air, while in colder climates, lower placement is better. It's also important to ensure that vents placed low on walls are not blocked by furniture. The optimal placement ultimately depends on your HVAC system's design, your home's specific heating and cooling needs, and the accessibility of the ductwork.

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.
