Frequently Asked Questions About Air Duct Repair

Homeowners aren’t alone in having questions—SumZero Energy Systems is here with clear, trustworthy answers to help you navigate every step of air duct repair.

Why choose SumZero for air duct repairs?
Is duct repair noisy or disruptive?
We aim for minimal disruption. Our team works quickly and cleanly, often completing repairs without interrupting your daily routine.
Can I add insulation to improve duct performance?
Absolutely. Insulating ducts—especially in unconditioned spaces—can improve efficiency and reduce energy loss.
Do you work with flexible and metal ductwork?
Yes—we repair and seal both flexible and rigid metal duct systems in basements, attics, and walls.
Will fixing my ducts improve indoor air quality?
Yes. Properly sealed and clean ducts reduce dust, allergens, and moisture buildup, making your home healthier and more comfortable.
How long does air duct repair take?
Most duct repairs are completed in 2–4 hours, depending on accessibility and the extent of the damage.
Can ductwork be repaired, or does it always need replacement?
Many duct issues can be repaired—like sealing leaks, tightening connections, or replacing damaged sections—without needing a full system replacement.
What’s included in your ductwork inspection?
Our $99 diagnostic includes a full evaluation of airflow, pressure imbalances, connection points, insulation, and visual inspection of the duct layout.
Can leaky air ducts really affect my energy bills?
Yes—leaky or damaged ducts can waste up to 30% of your heated or cooled air, leading to higher utility costs and uneven comfort.
How do I know if my air ducts need repair?
Look for signs like inconsistent airflow, high energy bills, musty odors, rattling noises, or visible gaps or damage in exposed ductwork.
