Your ductwork is one HVAC system component that you may not think about often. Since it’s hidden behind walls and ceilings, how can you know how dirty they are? Fortunately, there are easy-to-identify signs that tell you that professional duct cleaning is needed.
Indicators of Dirty Ductwork
If you recognize the following warning signs, contact a reputable HVAC professional to assess the condition of your ductwork and advise you whether duct cleaning can be beneficial.
- Mold growth – With the right levels of warmth and moisture, mold can thrive inside air ducts. Trouble signs can include a musty odor from vents or visible mold on the registers, the duct interiors or other HVAC components. Before you have the ducts cleaned, it’s important to have an expert confirm that mold is present. To prevent a recurrence, you’ll also need to solve whatever issues allowed mold to flourish.
- Excessive debris – If there’s a severe dust buildup on registers and visible particles waft out out every time the blower runs, it’s likely your ducts contain an unhealthy amount of dirt and debris. If you’ve had renovations done recently without properly sealing your HVAC system, a buildup of remodeling debris can also clog up ducts.
- Pest invasions – Given the opportunity, pests like rodents and insects can get into the duct system and find a cozy home. If you hear scampering noises or see any evidence of vermin infestation, call an exterminator to get rid of the invaders. Once they’re eradicated, schedule duct cleaning to remove any contaminants that can affect your air quality.
If your HVAC pro recommends duct cleaning, be sure to choose a contractor who follows the National Air Duct Cleaners Association (NADCA) standards. It’s also wise to look for well-trained technicians who understand the procedures to take to avoid contamination in your home and protect your costly HVAC equipment against possible damage.
