How Often Should You Clean Your Air Ducts? The Signs You Need To Know

Clean Air Ducts

Your heating and cooling system’s air ducts are an essential part. They channel warm and cool air throughout your home. Your HVAC system’s performance can be negatively affected if your air ducts become clogged with dust and pollen. These problems can be prevented by regular duct cleaning.

We’ll discuss the best ways to clean your air ducts, as well as how to spot signs of dirty ducts.

How often should we clean air ducts?

Experts suggest that your air ducts should be cleaned every three to five years. Your HVAC system, location, and climate will all affect the frequency of cleaning.

If you live in an area with heavy rainfall, your ducts may need to be cleaned once every one to two years. You may need to clean your air ducts every year if you live in an area with a lot of dirt and dust.

What is Duct Cleaning?

A technician will clean your HVAC system from the inside out when you have your ducts cleaned.

  • Grilles
  • Diffusers
  • Heat exchanger
  • Condenser/evaporator coils
  • Blower motor
  • Fan
  • Condensate pans
  • Supply/return ducts

Technicians will clean your ducts using handheld scrapers and brushes. To loosen dirt from walls, the technician might also use a rotary cable system or an air vacuum. Cleaning air ducts can take anywhere from two to four hours.

Here are some signs you need to clean your ducts

Excessive dust

You should clean your ducts if you notice excessive dust or debris in your home. Your HVAC system will blow dust into the house as debris such as pollen, pet hair, and dirt builds up. Excessive dust can cause respiratory problems as well as other health issues like cold and allergy symptoms.

A moldy or musty odor

Mildew and mold thrive in dark, damp places like your air ducts. Your ducts can become clogged with water, which can lead to the growth of mold, bacteria, and other organic growth. Your vents can then emit a foul-smelling odor. To remove bacteria and mold from your ducts, professional duct cleaners will clean them.


Your dirty air ducts could be home to rodents and insects. You should call an expert if you find more bugs than usual or near the vents’ exterior. You can get rid of pests and clean up the surfaces.

Reduced efficiency

If your HVAC efficiency drops, it is another sign you should clean your air ducts. Dirty ducts and vents can make it difficult for your cooling and heating system to distribute the air. This can lead to cold spots and hot spots as well as increased energy bills. Your HVAC system will run more efficiently if your ducts are clean.

Pros and cons of duct cleaning

The EPA doesn’t give any advice about how often you should clean your air ducts and does not consider it a part of HVAC maintenance. Duct cleaning does have its pros and cons.


Improve HVAC Efficiency

HVAC performance can be negatively affected by excessive dust and dirt buildup in your ducts. Your furnace and AC will work more efficiently if your ducts are clean. Cleaning your air ducts will result in lower heating and cooling costs. It can also increase the lifespan of your furnace or air conditioner.

Get rid of mold/pests

Mold and mildew growth in your ducts can be quite common in areas with wet climates. You should clean your ducts and get rid of any visible mold growth.

Remove Odors

Bad odors can be caused by all kinds of substances that could get into your ducts. These bad odors can be eliminated by cleaning and sanitizing your pipes.


Not clear on the effect of air quality

There is no evidence to support the claim that regular duct cleaning can improve indoor air quality, despite many claims. Although it is possible for duct cleaning to reduce indoor air particle concentrations, the EPA does not provide any scientific proof. Duct cleaning can also remove mold and other harmful pollutants.

May Knock Fixtures Available

You can clean the inside of ductwork that has been damaged or broken with rough brushes. This will allow you to remove fixtures and push through walls. This type of damage can have a major impact on the performance of your heating and cooling systems. We recommend that you always hire a professional to clean your air conditioning and heating ducts.

Tips to Keep Your Ducts Clean

These are just a few of the simple ways you can maintain clean air ducts.

  • High-efficiency filters are recommended for furnaces. Most air filters do a great job of keeping dust and particles from your vents. You’ll be able to clean your vents less frequently if the filter is good.
  • Make sure to have your HVAC service performed at least once a year.
  • To prevent debris from falling into your home during renovations or repairs, temporarily seal off and block any vents.
  • To prevent dust and debris from getting into your vents, vacuum your home often.

To remove as much dust as possible from the air, use a high-efficiency vacuum cleaner.
