Poorly maintained HVAC systems harbor bacteria, mold, fungi, and other pollutants that easily circulate into your space. These pathogens are transferred faster through the air ducts and can cause harm to humans and animals, hence the need for frequent duct cleaning.
It is crucial to know how often you should clean air ducts to improve air quality, maintain a healthy space, and reduce the maintenance cost of equipment. While you should clean them every 3–5 years, here are warning signs to help you know when your ducts are overdue for immediate cleaning.
Visible Mold and Strange Smells
How often mold develops in ducts determines how often duct cleaning should be done. Air ducts are damp and humid, making them the perfect places for mold to grow. Immediately after you spot mold and perceive a musty smell in the air, it is best to call a professional to help. During cleaning, the ducts will also be sanitized to prevent future growth.
Dirt and Debris
If your ducts look dusty and dirty, that should tell you that they need cleaning. With time, contaminants flow through them and build up in the system, and you will see that as dust. The dust keeps circulating through the air, and you know how detrimental that is to your health. It can trigger allergic reactions and cause other respiratory illnesses unless cleaned out.
After Remodeling or Renovating
If the building has recently undergone construction work, it is a sign to have your air ducts cleaned. Such projects can be messy, and debris will be left when the project is done, which will find its way into your ductwork. You don’t want to risk carcinogens and other toxins being left in your space, so you should call professionals to clean out the ducts. The same applies to moving into a new home; it is best to service the ducts, especially if there is no record of previous ductwork maintenance.
Spikes in Energy Bills
A drastic spike in your energy bills may indicate that your HVAC has efficiency issues, sometimes caused by dirty ductwork. The more dirt builds up, the more the system blocks and has to overwork to run efficiently. When you clean out the ducts, the HVAC won’t have to work as hard, using up less energy and saving you money in the long run.
