Air Duct Cleaning questions, answered by experts

You can do simple maintenance to keep it clean and operating in peak condition. Start by replacing the furnace air filters as directed–often, this is once every month or every three. Next, clean your air vents once a month, as they can help you see how much dirty air filters through. If you notice them becoming dirtier, you should have your ducts cleaned. With flexible ducting being more susceptible to tears, you’ll want to hire a pro to do the work for you. 

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.

If you discover a dead animal in your air ducts, address the issue promptly to prevent unpleasant odors and potential health hazards. Turn off your HVAC system to prevent further spread of contaminants and contact a professional HVAC technician or pest control specialist to remove the animal and clean the affected area. They have the tools and expertise to handle the situation, including removing and disinfecting contaminated ductwork. The technician will inspect the ducts for any damage or other issues that might have allowed the animal to enter.

Most smoke odors will subside over time if you air out the materials holding onto them, but they often won’t completely go away on their own. If you’re dealing with stubborn smoke odors on furniture and building materials, begin by deep cleaning and deodorizing with baking soda or activated charcoal. You may need to repeat treatment. If that doesn’t work, hire a smoke damage restoration company for help.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.
