To ensure your home is cozy and safe this winter, it’s important to invest in HVAC maintenance, including air duct cleaning. Air ducts are responsible for transferring warm air throughout the home. However, when they’re obstructed with clogs or infestations or dirty with mold, dust, or grime, they can decrease system efficiency and endanger your health. 

When Should You Schedule Air Duct Cleaning?

1. Spike in Energy Usage 

If you’ve noticed an unexpected spike in your energy bills, an issue with the system is likely to blame. Clogs, which decrease efficiency, are common culprits. When there’s a clog, the system has to work twice as hard to keep the home warm, resulting in more energy consumption and higher bills. Call an HVAC repair technician to inspect the ducts and clear obstructions. 

2. Signs of Pest Infestation

Rodents and other pests may make their home in your air ducts, particularly in the winter as they seek shelter from the cold. If you see signs of an infestation, have your ducts cleaned right away. Infestations aren’t just unpleasant, but they can also present a health hazard and result in damage to the system, as pests chew and claw holes in the ducts and reduce system efficiency. 

3. Persistent Allergy Symptoms

If you or other members of your household are experiencing unexplained allergy symptoms or respiratory issues, dirty ducts may be to blame. Dirt, dust, and debris can get caught in the air ducts and cause allergic reactions. Mold and mildew may also accumulate in the ducts and cause respiratory problems. If you and your family are sneezing, coughing, or developing asthmatic symptoms, clean your HVAC system as soon as possible. 

4. Foul Odor

If there’s a persistent, foul odor you can’t place, it may be a sign of a pest infestation or moldy ducts. Dirty ducts, clogged with pest droppings, debris, mold, mildew, or grime, can permeate the home with an unpleasant smell. Rodents can also sometimes get stuck in the ducts and cause a foul odor after death. Have an HVAC technician inspect and clear the system to remove the smell and any potential health hazards.
