Why is Spring the Best Time for Air Duct Cleaning?

air ductIt's finally warming up outside. You're spending more time in the sun and opening your windows to let the stale, dry winter air escape your home to make way for that fresh spring breeze. This weather makes you feel like cleaning — your car, garage, closet, and air ducts?

Air duct cleaning in spring may not be the first thing on your mind, but it's actually the best time of year to do so. Why? We'll tell you.

Dust + Humidity = Mold

You know how frequently you have to dust your furniture to keep it looking shiny and clean, so you can imagine what your air ducts look like after a year of use. But that dry dust that's accumulated in your ducts all winter gets sticky and can even cause mold when it's exposed to the spring and summer humidity. Cleaning your air ducts in spring, before they become a larger problem, is wise, especially if anyone in your family has respiratory issues.

Your System Needs a Break

As you transition from winter to spring (and then to summer), you're likely not using your furnace or air conditioner very often. Many people take this opportunity to open their windows instead. So, what better time to clean your air ducts than while you give your system a break from heating and cooling your home. That way, you won't have to worry about your system being turned off and your home growing uncomfortably cold or hot while your air ducts are being cleaned.

Improved Air Quality

When spring arrives, trees bud and flowers bloom, so there are a lot of pollens and allergens in the air. To avoid them getting into your home and wreaking havoc on your family's respiratory system, clean your air ducts.

Your pet's fur can also make its way into your ventilation system. And if someone in your home smokes, the chemicals from the cigarettes spread throughout the house through the vents, too.


Cleaning your air ducts regularly, no matter when you do it, will help you save money in the long run because your system won't have to work harder to heat or cool your home. Instead, it will work far more efficiently, resulting in a longer lifespan.

Best Days to Take Advantage of Duct Cleaning

Yes, spring is a great time to have your air ducts cleaned. But what types of days are best for this job?

  • Rainy days — Rain confines pollens to the ground or trees, and, in some cases, washes them away entirely. A rainy day, when pollens aren't floating through the air, is the perfect time to have your air ducts cleaned because fewer pollens will enter your home through your opened windows.
  • Cool temperatures — Hot, dry temperatures only make pollens worse. Check the forecast. If it predicts cooler temperatures, it might be a good idea to schedule an air duct cleaning.
  • End of spring — Anytime in spring is a good time for duct cleaning, but the end of spring is ideal. Most plants are fully bloomed, meaning there are fewer pollens in the air and fewer pollens to get into your home when your windows are open.

So, whether it's been several years since you last cleaned your air ducts, or just a few years, take advantage of this optimal time for cleaning. You'll have peace of mind knowing your HVAC system is clean and efficient.
