When is the Best Time to Do Furnace & Duct Cleaning?

Whether you’re trying to get a jump on your spring cleaning or you’ve just finished renovations, furnace & duct cleaning is an important part of maintaining a clean home and indoor air quality. But you might be wondering – is there a certain time of year that is best to get it done? While many people lean towards the fall months to get their furnace & ducts cleaned, this is a service that is offered year round to homeowners and property managers alike. In this week’s Dear Keven letter, Keven & Tami talk about the indicators that you’re due for a furnace & duct cleaning and share some tips for keeping your HVAC system in tip-top shape.

How Do I Know If I Need My Ducts Cleaned?

Keven mentions a few things that you can do to see if your home is due for a furnace & duct cleaning:

  1. Take out your furnace filter from the filter cabinet and peek in with a flashlight – is there a build-up of dust & debris?
  2. Take the front cover off of the furnace – does it look dusty & grimy?
  3. Remove a few floor vents and cold air returns – do you see lots of dust, debris, or crumbs?
  4. Do you find yourself changing your furnace filter more frequently?

If you answered yes, to any of these questions, you’re probably due to get your furnace & ducts cleaned.

Other Factors that Can Impact the Timing of Your Duct Cleaning:

Allergies & Asthma:

Some people with allergies or asthma may notice that they have a harder time breathing, sneeze frequently, or be more bothered by the air quality in the home if the ducts haven’t been cleaned in a while. These individuals may benefit from getting their ducts cleaned more frequently – every one or two years – than other homes.


If you’ve recently done renovations where a lot of construction dust was created, it’s a good idea to get your vents cleaned. This being said, we recommend you wait a week or two after your renovations are complete before booking your duct cleaning, so that all of your construction debris has a chance to settle.

Neighborhood Construction:

Depending on the nature of the construction in your area, there is often a huge amount of construction dust, dirt, and other debris that is made airborne in the process. Especially in the instances of road or sidewalk construction, this dirt and debris can find it’s way into your home, decreasing your home’s air quality and dirtying up your duct system.
