alturascontractors.com/when-to-clean-your-air-ducts/
Your health is directly related to the indoor air quality around you. The presence of dust
particles, irritants, pollen or mold spores can be extremely dangerous to inhale.
Just like any other HVAC system, air ducts require regular maintenance to ensure
maximum efficiency. Here a question arises: When to Clean Your Air Ducts?
As a general rule of thumb, the National Air Duct Cleaners Association (NADCA)
recommends air duct cleaning every 3 to 5 years.
What is air duct cleaning?
Duct cleaning generally refers to the cleaning of various heating and cooling system
components of forced air
systems.
Air ducts are passageways that transport cooled and heated air throughout your house.
Just like any other HVAC system, air duct cleaning and regular maintenance ensure
maximum efficiency. If not cleaned timely, the accumulated dust and dirt gets filled with
contaminants and air pollutants that can not only harm your indoor air quality, but can also
cause your hvac system to work harder.
Consequently, this not only increases your energy bills, but it can also significantly
shorten the life expectancy of your system.
Your home’s cooling system will perform better with regular maintenance, and air duct
cleaning to ensure the longevity of your entire HVAC system.

If you are uncertain about when and how often to clean air ducts, here are some common
signs of dirty air ducts
Ducts clogged with dust and debris
In normal situations, air ducts do not expel visible dust or debris when the heating and
cooling system is switched on, and the air starts to flow through the ducts. Therefore, if
you see visible presence of dust is probably a clear sign of dirty air ducts.
Dusty surroundings
If you notice:
Your home or commercial area seems dusty.
Every surface is coated with dust immediately after cleaning the area.
If you notice dust coming out of the vents every time the HVAC system kicks on.
These are signs of dirty ducts. You probably need to have your ducts cleaned.
Remove a vent cover filter and take a look into the ductwork. If the metal is covered in
dust and you see dust and dirt both inside and outside your ducts most likely need to be
cleaned.
Make sure you replace your HVAC system air filters frequently to prevent future dust
buildups.
Ducts Infested with Insects

3. 3/5
Even the cleanest homes can have dirt, dust, pet dander, and all sorts of harmful
contaminants lingering in the air ducts. From time to time, mice, squirrels, rodents and
insects can make their way into your air ducts. They leave behind all sorts of bacteria and
droppings. This allows tiny fecal spores to sweep along the ducts. These spores can then
make their way into your home and contaminate the quality of the air you breathe.
Keep in mind that a bacterial infestation might require more than air duct cleaning. If the
issue is overlooked, it could lead to serious damage to the hvac equipment as well as to
the health. Moreover, an HVAC system that doesn’t work efficiently, leads to higher
energy bills.
Frequently clogged filters
No doubt filters need to be changed periodically however, they shouldn’t be clogged after
every few days of replacing them. If you have to change hvac filters every now and then
this could be an indication of a deeper problem. This is a sign that you need to check on
the air ducts.
Rising Energy Bills
Your heating and cooling costs should be relatively predictable from year to year. If you
notice that your electricity bill has suddenly sky-rocketed, dirty ductwork might be to
blame.
With the continuous use, the ductwork can get accumulated with too much dirt that air
can not flow freely and efficiently through your home’s hvac system. Thus both your
furnace and air conditioner are forced to work harder to maintain a comfortable indoor
temperature. This causes higher utility bills for you and your family.
Unpleasant odor from ducts
Another evident sign of the presence of debris in your commercial or industrial hvac duct
system is the ducts emanating unpleasant odor. It is a sign you should conduct serious
ventilation system cleaning. It is best to consult an expert technician who can inspect the
air ducts for anything that could be emitting the bad smell.
Strange and unusual noises in the ductwork
If you have lived in your home or owned a building or comercial area with an hvac system
installed, you definitely know how the hvac system sounds when it is operational. Your
ductwork shouldn’t make a lot of noise while operating. If you hear anything more than
the general motor sound, your ducts could be experiencing some problems.
Inadequate air flow

4. 4/5
Air that travels through the duct work should deliver relatively consistent airflow from
room to room. If you notice that a bathroom, bedroom, or other room in your home
doesn’t receive the same level of airflow as other rooms, inconsistency could be the
reason. Dirty air ducts, accumulation of debris in your air ducts, any leaks you have in
your ductwork ultimately decreases the efficiency and increase your energy bill.
All of this causes your system to have to work harder. Hiring an air duct technician to
clean your ducts won’t only remove harmful contaminants, but can also rule out potential
leaks.

Furthermore, an improper cleaning job could damage the ducts, resulting in expensive
repairs. We recommend scheduling regular air duct cleaning services from a professional
HVAC technician to keep your system in the best possible shape.
How often to clean air ducts?
Experts advise having your air ducts cleaned after every 2 to 3 years to prevent greater
problems before they start. However, homes with pets or children with allergies or
respiratory problems should have their air ducts professionally cleaned more frequently
than the recommended average.
