"Nasir arrived on time, which to me is a huge plus. So many contractors schedule time and either arrive late or are no show. He did an excellent job cleaning the dryer vent and his price was very competitive. So I decided to hire him to clean the air ducts as well."

Air Duct Cleaning questions, answered by experts

No, not all houses have ducts. It would be safe to say, however, that most modern houses do. The reason is that older houses had boilers in the basement that heated from the bottom up and often vents weren’t built into the house. Another reason is that older homes don’t have air conditioning (because it didn’t exist) and use radiators for heating. Since radiators don’t require ductwork, it wasn’t built.

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.

Return air ducts should generally not be installed in rooms with high humidity, contaminants, or strong odors. This includes bathrooms, kitchens, garages, closets, attics, and furnace or boiler rooms. Placing vents in these areas can draw moisture, fumes, odors, and potentially hazardous gases like carbon monoxide into your HVAC system, which can damage ductwork, promote mold growth, and compromise your home's indoor air quality and safety. According to the International Code Council, there are some exceptions. For example, a return duct may be placed in a kitchen if it is at least 10 feet away from cooking appliances and serves only that room. Similarly, a garage can have a return duct if it is part of a dedicated forced-air system that only serves the garage. For optimal performance, prioritize installing return air vents in central locations and rooms with consistent temperature needs, such as bedrooms and living spaces. If you are unsure, consult a professional duct installer for guidance.

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.

No, because closing air vents could damage your HVAC system. Closing a vent will only keep the air in the duct, not redirect it to a room or zone where you’d prefer it to be. That air will become trapped within your ductwork, creating a buildup of pressure that can damage the ducts and cause leaks.
