  • How Can I Tell if My Air Ducts Need to Be Replaced?

    Air ducts aren’t designed to last forever. Over time, normal wear and tear can affect comfort, air quality, and efficiency. The recommended frequency for duct replacement depends on the material quality, maintenance frequency, and environmental conditions.

    Here are some common signs that it might be time to replace your ducts:

    • Air ducts that are more than 15-20 years old.
    • Visibly damaged ducts, such as large holes or corrosion.
    • Uneven temperatures due to leaky or poorly insulated ducts.
    • Persistent issues, such as high energy bills or poor air quality.

    If you notice any of these warning signs, give us a call at (541) 250-3845. Our team uses high-quality materials to replace old or damaged ducts for improved performance and efficiency.
