10 Signs Your Air Ducts Need Cleaning

odour sign ducts need cleaning

There are some tasks you know you need to take care of right away. Others, you may be able to put off until later.

But it is the tasks you cannot see that tend to get put off the longest, because you don't even know they need doing!

Air ducts tend to fall into this third category for obvious reasons.

But sometimes those same air ducts can get creative in letting you know they need your attention, which is what we will address in this post.

10 SOS Signs Your Air Ducts May Be Sending You

If you have noticed any of these 10 signs happening in your home or workplace, it may be your air ducts sending you an SOS!

1. Dust

When your HVAC system kicks on and air starts to flow, and you see a small initial puff of dust come out of your air registers, this is a good indication there is more dust where that puff came from.

Normally, air ducts will not emit any visible dust or debris when the HVAC unit cycles on and air starts to flow through the ducts.

Visible dust could also be due to very dusty air registers. However, if you remove and clean the air registers inside and out and the problem remains, it is likely due to trapped interior dust instead.

2. Odour

One telltale sign there may be debris lurking inside your air duct system is odour.

When something in your home smells "off" and you’ve checked every possible place but you can’t find anything amiss, the culprit might be inside your air duct system.

You can try to do a test by getting right up close to one or more air registers and giving them a good sniff—you may be able to verify your suspicions this way. Another way is to have your HVAC technician take a look inside your air ducts to check for trapped debris, mould, or mildew that might be emitting the same odour.

3. Mould or mildew

Sometimes, it is possible to actually see black or grey/brown mould or mildew growing on and/or around the outside of your air registers.

Unfortunately, when this occurs, it usually signals a more extensive problem with mould or mildew that may represent an extensive remediation project.

However, if the mould or mildew is found to be contained completely within your air ducts themselves, the process of vacuuming them out, sanitizing, and deodorizing them can literally save you from having to take apart your home to clean the mould out.

4. Visible debris

If you take off an air register and see that dust, pet dander, and other debris has built up inside the end of the duct, this can indicate that your air ducts have become clogged.

The best way to tell is to try to remove just the dust and debris you can see. If more appears again later, it is probably time to call in the pros for a professional air duct cleaning.

5. Clogged air filter

One solid indicator that dust and debris has begun to build up in or around your HVAC system is a filthy disposable or reusable air filter from your HVAC or furnace system.

If you catch this early and get on a regular rotation of cleaning or replacing your air filters, sometimes this can nip the issue in the bud and prevent the need for a full air duct cleaning.

6. Dirty A/C coil and interior parts

If your air conditioner’s coil and interior parts are packed with dust, debris, mould, mildew, and/or other detritus, this is a good indication that dust trapped somewhere else in the HVAC system has begun to travel through the air ducts to impact external or peripheral system components.

You will definitely want to give your HVAC a thorough cleaning, but if the dust quickly returns, you may need to clean the entire system to take care of the problem once and for all.

7. Uneven air flow

When the air seems to flow with good strength from some air registers in certain rooms, but there is not much air pressure flowing out of registers in other rooms, this may be caused by dust and debris blockages forming inside your air duct system.

It could also be caused by leaky ducts that have become ripped or degraded, so be sure to ask your HVAC technician to check for both during your HVAC inspection.

8. No record of prior air duct cleaning

It has only been within the last several years that modern air quality technology has really become a part of public knowledge.

So if you have an older home (10 years or older) and you possess no record from the prior owner(s) that the air duct system has ever been cleaned professionally, it probably hasn’t ever had this service.

9. Your home or workplace gets really dusty

When it seems like every time you check, a thick layer of dust has accumulated on interior surfaces yet again, this is a good indication of a greater amount of dust and debris that is getting pushed out through your air duct system every time your HVAC system cycles on.

10. Your health is poorer than normal

Sometimes the first sign you will get that your air ducts are clogged appears in your own respiratory system.

Sneezing, coughing, wheezing, feeling fatigued or mentally foggy, continually battling allergies, increased asthma attacks, and similar symptoms can all indicate the presence of recirculating debris and toxins in your indoor air system.

Want Cleaner, Purer Indoor Air? Get it for Less This Month!

Save on duct cleaning this month

Indoor air quality has come a long way over the last decade or two. And it is a good thing, too, because overall air quality has been on a downhill slide for even longer.

As we explain in more detail in this post, sometimes all that is standing in between our fragile lungs and all the toxins circulating in the air are the protections we choose to put in place.

These protections—such as more powerful air filters, air duct cleanings, purification, and ventilation systems—are currently optional.

But if you are living with seasonal allergies, asthma, chronic illness, or serious disease, these optional protections can literally change your family's quality of life for the better.

Here at Clean Air Solutions Hamilton, we are eager to help you enjoy the cleanest, purest indoor air possible, and we are willing to slash our own prices to help you do it! Read on to learn about two extra-special offers for this month and how they can clean and purify your indoor air.

June Savings: Get $50 Off Any Duct Cleaning Package

Clean Air Solutions Hamilton was founded by our sister company, Shipton’s Heating & Cooling, to address the growing need in the Hamilton and surrounding areas for effective, efficient, affordable indoor air quality solutions.

Our signature product is now and has always been the professional air duct cleaning packages we offer. While more information is now being publicly distributed about the benefits of having your air duct system professionally cleaned, the number of homeowners who have had this service performed are still in the minority.

This also means the vast number of homes have anywhere from one to three or more decades’ worth of dust, debris, pollen, mould, detritus, toxins, and other pollutants trapped inside their air duct system.

Unless the previous homeowner gave you a record of a prior air duct cleaning service, it is unlikely your home's air ducts have been serviced. This is why we believe that, before you install any air purification equipment or take other measures to clean up your indoor air, you should start with an indoor air duct cleaning service.

Then you can proceed to add the best indoor air quality equipment for your family’s specific health and wellness needs.

You can also take steps to keep your air clean by choosing which house cleaning products, craft supplies, and personal care products you use inside your home.

The average indoor air duct cleaning service will take between three and five hours, depending on the size of your space. We currently offer three different professional indoor air duct cleaning packages:


With this package, we will professionally clean and vacuum out your air duct system (both supply and return air ducts), clean your air registers, and then deodorize and sanitize your entire air duct system.


With this package, we will do everything in the Bronze package PLUS clean your furnace fan compartment and your air conditioner coil.


With this package, we will do everything in the Bronze and the Silver packages PLUS complete a 21-point inspection and maintenance check on your furnace.

To redeem your $50 Off Duct Cleaning discount, contact us at 905-544-2470 or just fill out this easy online form.

Breathe Clean Event: 20 Percent Off Indoor Air Quality Equipment

As it sounds, our Breathe Clean Event is all about ensuring pollen, dust and mites, mould and mildew, vehicle emissions, airborne toxins, volatile organic compounds, and other pollutants are made unwelcome in your home.

Once these types of airborne pollutants get inside your home, they are added to your indoor air supply and re-circulated again and again through your air duct system. Some may take up residence in your carpeting or draperies. Others may make themselves at home in your pillows, mattresses, and bed linens.

Some may get trapped inside your air duct system and get continuously blown back out through your air registers when your air conditioner or heater cycles on.

But regardless of how they get in and trapped inside your home, our efficient, effective, and affordable indoor air quality equipment can get them out.

This month, save 20 percent on each of the following appliances:

  • Whole Home HEPA Filters. A whole home HEPA filter can trap and remove 99.97 percent of airborne toxins, including tiny particles the size of 1/100th the width of a single human hair!

  • Whole Home UV Purification Systems. Using ultraviolet light to purify your indoor air destroys even the smallest toxic particles right at their source. Best of all, these units are self-cleaning and self-maintaining and come in a variety of sizes to suit any size space.

  • Heat Recovery Ventilators. A heat recovery ventilator, or HRV for short, puts an impenetrable barrier between outgoing stale air and incoming fresh air. It also takes toxins, pollutants, and excess moisture out of the air as it comes into your home, purifying it on the spot.

  • Whole Home Humidifiers. There are two kinds of humidifiers: bypass flow-through and steam-based. Either can be installed to keep your home humidity-balanced for optimal health. This becomes especially important in transitional wet-dry seasons and in dry seasons.

To redeem your 20 percent Breathe Clean discount, contact us at 905-544-2470 or fill out this easy online form.

Is it Time to Get Your Air Conditioning Serviced? 5 Ways to Tell for Sure

time to service air conditioner

Here at Clean Air Solutions Hamilton, we take our role in the local community very seriously indeed.

As we see it, our job is to do our utmost to make sure you and your loved ones have the cleanest, freshest, purest indoor air to breathe.

To do this, we are constantly researching the latest cutting-edge services and products to control your indoor air quality to the level your family requires.

From ventilation, purification, filtration, and humidifier/dehumidifier solutions to indoor air duct cleaning and dryer vent cleaning services, we aim to serve as a one-stop resource for any air quality issues you may be experiencing.

But there is one thing you can do to maximize the results of any air quality solution we provide to you, and that is to take the time annually to ensure your HVAC and furnace systems are in tip-top condition.

In this post, learn how to know it may be time to get your air conditioner serviced.

5 Signs Your Air Conditioner Needs to be Serviced

No one loves scheduling their appliances’ annual maintenance tune-ups.

Of course, we don’t tend to love going to the dentist or having our annual wellness doctor check-up either, but we do these things because they provide us with peace of mind as well as the chance to catch any major health issues in the early stages.

The same model works just as well when applied to your air conditioner. Yes, having your A/C inspection and tune-up appointment annually will require a little of your time and money. But it can (and often will) prevent much more costly and inconvenient major repair issues or outages later on.

Here are five common signs that you can watch for to indicate your air conditioner should be serviced soon:

Sign 1: You hear strange sounds (and you are pretty sure your house isn’t haunted)

Air conditioners that are in good working order should make predictable noises. For instance, you may hear the slight sound associated with your A/C unit cycling on and off. But loud pops, bangs, rattles, buzzes, or clanks are neither normal nor healthy.

If you hear these sounds, it is time to call in the pros to take a look around and see what may need tightening, lubricating, repairing, or replacing inside your air conditioner.

Sign 2: You get sticker shock every time your cooling bill arrives

This may not be readily apparent in “transitional” months, when the outside weather leaves you poised in between cool and warm temperatures. But wait until summer arrives in earnest and you compare this year’s cooling costs with last year’s. Then you will have a clearer picture of whether it is costing you more to cool the same space.

When this happens, it might indicate something as simple as a clogged filter and air vents. Or it could mean your A/C unit is approaching the end of its useful efficient life and a replacement may be in your future.

Sign 3: You and your family seem more prone to spring allergies or breathing issues than usual

Dirty air registers, ducts, and vents can all be implicated in this type of seasonal issue. Over time, the system of air registers, ducts, and vents that your air conditioner relies on to do its job can get dirty, dusty, and clogged with all kinds of debris.

As well, in winter, insects and small animals might have found your indoor air ducts a handy refuge where they could shelter from the cold, leaving behind debris, shell sheds, feces, and other unwelcome calling cards.

As this matter gets pushed out into each room of your home, it can result in you getting sicker quicker. You might think new spring pollens are all to blame, but chances are quite good your immune system was already compromised from fighting the toxins already present in your air duct system.

Sign 4: You hear the A/C cycle on, but the airflow through the air registers seems weak from room to room

Here, there are two potential issues at work. The first issue is referenced in Sign 3 and is most likely due to clogged air ducts that are making your air conditioner work too hard to try to push the air through to each room.

The second issue relates to an entirely separate repair need in the air conditioner’s compressor. As the compressor begins to fail, it will not work as effectively to push out temperature-controlled air. Here, the earlier you catch and fix this issue, the less likely you will need to replace additional worn-out components, or, worst of all, the entire HVAC unit.

Sign 5: You find moisture leaking out around or underneath your unit

Moisture might be condensation. It might also be refrigerant. Either way, this needs to be fixed pronto before a more serious issue presents itself. Excess condensation that pools near or beneath the unit could indicate a blocked drainage issue. Left unaddressed, you might end up with mould or mildew or—even worse—water damage inside your house from a major leak.

Refrigerant is a known toxin; if it’s leaking out of your air conditioner, it can cause damage to both you and your pets, and to your air conditioner itself.

Why Schedule Your Air Conditioning Inspection & Maintenance Service Call Now

The main purpose of having your HVAC unit inspected and maintained annually is to ensure your air conditioner is working safely and efficiently. Secondary benefits include early detection of small repairs before they become major expenses.

Spring is the perfect time to schedule your HVAC inspection and also have your air ducts cleaned.
