A close-up view of a heavily dust-coated HVAC air duct, highlighting the need for thorough cleaning to improve air quality.

Your HVAC system works hard to keep your home comfortable year-round—but when your air ducts are dirty, leaking, or damaged, your indoor air quality and system efficiency can suffer. At Eco Property Services, we specialize in air duct cleaning and repair for homes in Bay Area and nearby areas. Here are the top 5 signs it’s time to give your ductwork some attention.

1. 🌬️ Uneven Heating or Cooling

If some rooms in your home feel hotter or colder than others, your ducts might be:

• Leaking air before it reaches certain rooms

• Clogged with dust or debris

• Poorly connected or deteriorating

Professional duct inspection and repair can restore balanced airflow and improve comfort.

2. 🤧 Increase in Allergies or Respiratory Symptoms

Dust, mold, pet dander, and other allergens collect inside your ductwork over time. When your HVAC system kicks on, it can blow these pollutants into your living space—making allergies worse.

Air duct cleaning helps create a healthier indoor environment, especially for homes with pets, kids, or asthma sufferers.

3. 💨 Visible Dust Coming from Vents

If you see dust blowing out of your vents when the system runs, or if the vent covers are covered in buildup, your ducts likely need a deep clean. It’s also a sign your air filter may be clogged or not functioning properly.

4. 💸 Higher Energy Bills Without Explanation

When air ducts are leaking or blocked, your HVAC system has to work harder to maintain the set temperature—resulting in increased energy consumption and higher monthly bills. Cleaning and sealing your ducts can improve HVAC efficiency by up to 20%.

5. 🐀 Pest Infestations or Strange Odors

Rodents, insects, and mold love dark, dusty ductwork. If you smell musty odors, hear scratching in the vents, or notice droppings near your air returns, your ducts may be infested or contaminated.
