Air Duct Cleaning Guide – When to Clean Your Furnace & Air Ducts


When was the last time you had your HVAC system cleaned? While it could be the last thing on your list of regular maintenance, it must be noted that keeping your furnace and air ducts clean is crucial to ensuring that you and your family breathe fresh, healthy air. Over time, air ducts accumulate dust, mites, mold, and other debris that can hinder airflow and cause your furnace to overheat. In the worst-case scenario, your HVAC system could start or contribute to a fire!

To ensure your family is kept safe and in good health, it’s crucial to have your furnace and ducts professionally cleaned. Given that the costs can seem rather high, many homeowners skip this process. Nevertheless, regular cleaning could prevent more consequential expenses down the line by catching minor issues before they become major replacements. 

Cleaning is recommended if you notice the following signs:

Your family members are showing symptoms of allergies and illness

A clean air duct helps safeguard your respiratory system. If you or someone in your family has been showing more allergy symptoms or getting ill more frequently, your HVAC system could be the culprit. Once you notice any symptoms indicating allergies or asthma or any other respiratory problem that doesn’t seem to go away, consult your doctor immediately. Your doctor will be able to rule out the symptoms and recommend the next course of action. 

Should you find that your family’s health problems have something to do with the air inside your home, schedule a thorough cleaning as soon as possible. You’ll often find that symptoms can diminish quite rapidly once the air is clean!

You’ve just finished a renovation

Renovations can be messy and leave dust and debris flying about in your home, which could be filtered through your furnace. Over time, this could create inefficiencies in your system, resulting in your HVAC unit working overtime. As your unit works harder to spread cool or warm air, it uses more energy. If left unattended for a long period of time, the dust could put a strain on the entire system and result in its early demise.

To avoid a costly replacement and high energy bills, make a point of scheduling routine air duct cleaning.

Your unit is expelling debris whenever it’s first turned on

Another sign that your air ducts need cleaning is when you notice your unit expelling visible particles such as pet hair and dust whenever it is turned on. A little dust in the furnace is still considered normal, but when your unit starts to discharge debris, you’re going to need a cleaning ASAP.

You’ve got a possible vermin infestation

The last thing any homeowner wants to deal with is creepy crawlers taking over their living spaces. If you suspect that unwanted vermin have infiltrated your air ducts, contact a professional duct cleaning company immediately.

You notice mold growing in the vents

Once in a while, it’s a good idea to remove the cover of your air ducts and give it a sniff. If your vents are constantly exposed to wet conditions, there is a high chance of mold growth, which can be dangerous for you and your family. If there is a distinct musky smell or any signs of mold, clean a certified HVAC cleaner right away.

It’s time to call for professional duct cleaning!

Although there is no hard-and-fast rule for how often your furnace and air ducts should be cleaned, the general consensus is that you should bring in a professional every three to five years. If you notice any of the indications above, however, move up your schedule and call your local air duct cleaning experts. Keep in mind that if your household contains pets, someone with allergies or asthma, or smokers, cleaning should be conducted more frequently.
