Your home’s vents and ducts work around the clock to keep air flowing—but when was the last time you gave them a second thought?

If you're not sure, you’re not alone. The good news? With just a few simple steps, you can check your airflow, identify common problems, and even perform a light DIY clean to help your HVAC system run more efficiently.

What Do Ducts Actually Do?

Your ductwork is the delivery system for clean, climate-controlled air throughout your home. It also plays a key role in removing dust, allergens, and other particulates from the air you breathe.

When working properly, this system quietly supports your comfort and health. But when neglected, it can contribute to everything from musty odors to recurring allergies—and even rising energy bills.

How to Maintain Your HVAC System (Between Cleanings)

A full professional duct cleaning is the gold standard—but routine care goes a long way. Use these quick tips to keep your HVAC system performing at its best:

  • Dust and wipe all accessible vents.
  • Check that vents aren’t blocked by furniture or clutter.
  • Vacuum regularly—especially if you have pets.
  • Change HVAC filters as recommended (typically every 1–3 months).

When to Check or Clean Your Ducts

Certain life moments call for a closer look at your duct system. If any of these apply to you, consider scheduling an inspection or light cleaning:

  • You’ve just moved into a new home.
  • You’ve completed renovations or remodeling.
  • Your energy bills are unusually high.
  • You notice persistent odors or indoor allergies.

Bonus tip: Run a DIY home energy assessment or check your thermostat settings to boost energy efficiency year-round.

Signs You Should Call a Professional

While basic maintenance is helpful, some issues require expert attention. Contact a professional if you notice:

  • Visible mold growth near or inside your vents
  • Rodent activity, such as droppings or scratching sounds
  • Heavy dust buildup that returns quickly, even after filter changes
