Many homeowners are curious about the maintenance of their HVAC system’s ductwork. In particular, they wonder if the ducts need to be cleaned on a regular basis. Although you may not need to have a scheduled routine duct cleaning every year, there are some circumstances that may be improved through an air duct cleaning. If you live in a home with smokers, people suffering from asthma, or pets with lots of dander or shedding, you may experience improved air quality through achieving cleaner ducts. In addition, if your home has suffered water damage or undergone recent remodeling, you may want to have an HVAC professional inspect your ductwork to make sure there is no clogging or damage to the system.
It’s not uncommon or dangerous for air ducts to collect some dirt and debris over time. But if this amount becomes excessive, it can affect your home’s air. According to the National Air Duct Cleaners Association (NADCA), over 40 pounds of dust collects in your home each year through everyday living. Now think about what your ducts are circulating. Although having dirty air ducts doesn’t necessarily mean you’re inhaling unhealthy air, a person with respiratory issues or allergies to dust or pet dander likely won’t benefit from those contaminants continuously wafting through the air. Having your air ducts and AC filters cleaned will allow your system to run more efficiently while improving your home’s air quality in the process.
Another reason to clean your air ducts? Mold. According to the U.S. Environmental Protection Agency, if there is visible mold growth in your ductwork or other components of the system, you should probably have your heating and cooling system cleaned. Although some substances may look like mold or mildew growth to the untrained eye, if you’re unsure it’s better to have this issue addressed by a professional. Mold growth isn’t as common as some experts may have you think, but it does happen. If you do have mold in your ducts, an HVAC specialist can determine the best solution and possibly pinpoint the cause of the mold growth, such as a water leak. You’ll want to find out the root of the problem because if the conditions causing mold aren’t changed, the mold will keep returning.
Finally, if your ducts are infested with rodents, insects, or other vermin, a duct cleaning is certainly worth considering. When it comes down to it, is air duct maintenance something you need have done every single year? Probably not. But if you’re experiencing any of the above situations or noticing dusty air, call a professional air conditioning company to have your heating and cooling system evaluated.
