How Often Should Air Ducts Be Cleaned?

Your heating and air conditioning system keeps your home comfortable all year long, regardless of the weather outside. Many may not know this, but maintaining the air ducts that transport warm or cold air throughout your home is an important part of keeping your HVAC system in top condition.

Over time, dust and other allergens can build up in the ducts and reduce the overall efficiency of your system. Not only that, but enough buildup can become a fire hazard if left untreated. Regular air duct cleanings can keep your home safe and clean.

How often should you have your air ducts cleaned? Blake Brothers has years of experience in the HVAC industry, and we’re happy to provide some insight. To help you diagnose HVAC issues in your home, we have created an outline that illustrates the importance of ductwork cleaning and summarized the main signs of dirty air ducts.

Is Ductwork Cleaning Necessary?

Your HVAC system circulates all of the air throughout your home using air ducts, meaning that dust, pollen, and other allergens in the air can build up over time. This reduces the overall air quality inside your home, leading to an increase in allergy symptoms and respiratory issues.

Having a professional deep clean your air ducts every few years reduces the amount of contaminants in the air while keeping your home safe. Dust is quite flammable, and a buildup in the ducts can increase the risk of a fire. Clear ducts also mean your HVAC system can run more efficiently, reducing your energy bill each month.

Signs Your Air Ducts Need to Be Cleaned

You don’t see the inside of your ducts on a daily basis, so it can be tough to tell whether or not you need professional cleaning. While you may not be able to see the dust levels in your ducts, other clues around your home can help. Keep an eye out for these warning signs that it may be time to get in touch with a professional HVAC technician:

1. Changes to Your Home

It’s exciting to move into a new home and begin a new chapter in your life. If the previous owners smoked, owned pets, or didn’t service the air ducts in the last three years, it may be a good idea to clean them as part of the move-in process.

A professional duct cleaning service may also be beneficial for current homeowners after a serious renovation. Building a brand-new kitchen or adding an extension to the home is exciting and new, but it can also create a ton of dust and sawdust.

All of the construction work kicks up a ton of dust and contaminants that can filter into your ducts and clog them up, and a duct cleaning can reduce contaminants and keep your home clean.

2. Mold Growth or Strange Odors

Mold thrives in humid, dark areas, and the inside of an air duct is the perfect spot. Your air ducts can have higher moisture levels than other areas of your home, and mold will take advantage of that.

If you notice visible mold in areas of your home, smell a musty odor in the air, or notice physical symptoms such as throat irritation and coughing, it could point toward mold in your ducts. An experienced HVAC technician can find the source of the mold, safely clear it out, sanitize the area, and perform professional air duct cleaning services to prevent mold from coming back in the future.

3. Pest Infestation

Small critters and creepy crawlies can sneak into your ducts and make themselves at home. Not only do they now have a series of tubes to crawl through and spread throughout your house, but they also spread their own debris and contaminants throughout the ducts.

If you see an increase in critters near your vents or notice an odd smell coming from your air ducts, you could have a bug highway in there. A professional air duct cleaning can evict any unwanted guests in no time.

4. Dust and Debris

Dust naturally accumulates on your cabinets and tables over time. However, a consistent layer of dust that always seems to come back no matter how often you use the duster is a cause for concern.

As more dust builds up inside the ducts, additional dust is spread throughout your home and into the air. Dust, pet dander, dead skin cells, and other contaminants can decrease your air quality and lead to respiratory symptoms. If you notice a substantial amount of dust in your house, this is an indicator it’s time to have your air ducts cleaned.

5. Air Filters Are Clogged

Your heater and air conditioner have a series of filters that help collect dust and other contaminants before they can travel through your ducts. These filters can fill up quickly, and this can cause dust to build in the ducts. Regularly replacing your filters and cleaning off your vents can reduce the overall contaminants in your air and help keep your ducts clear.

6. Poor Airflow in the House

Although there is no definitive answer regarding how often you should have your air ducts cleaned, poor airflow is a clear sign of ineffective ductwork in your home. As dust builds up in the air ducts, it can interfere with airflow and impact the efficiency of your system.

When your system starts up, you should feel a strong current of air coming from your supply vents. If you notice a weaker airflow or inconsistent heating and cooling in different areas of your home, it could indicate a buildup of dust and other debris.

7. High Heating or Cooling Bills

If your HVAC system can’t run at full efficiency, it needs to work harder to maintain the desired temperature in your home. This can lead to an increase in your heating and cooling bills each month.

While it’s normal for your bill to fluctuate slightly from month to month depending on the weather, a sudden increase could be a sign of a dust clog in the air ducts.

8. Strange Noises

As your heating and cooling system pumps air through your home, all you should be able to hear is a faint humming from the system and a gentle rush of air from the vents. Hearing odd noises such as whistling can indicate a problem with the air ducts.

9. No Records of Previous Air Duct Cleaning

How often should HVAC ducts be cleaned? No matter how long you’ve lived in your current home, there should be a written record of all maintenance services performed on the property. Take a look at any records you have and see when was the last time an HVAC technician cleaned the ducts.

If there’s no record of any cleanings, or the last cleaning was more than 2 or 3 years ago, it may be time to schedule an appointment.
