​HVAC FAQs – Frosty’s Answers Your Home Comfort Questions
How long do air ducts last before they need to be replaced?
Most duct systems have a service life of 10-15 years, and most HVAC professionals recommend starting inspections once ducts reach about 20 years old
What are the signs that my ducts are damaged or failing?
Homeowners will notice inconsistent room temperatures, weak airflow, unusual noises, musty odors, or a sudden rise in energy bills when ducts are deteriorating. If you notice bacterial build up starting to form on any of your hvac supply or returns.
In Texas heat, how often should ducts be replaced?
Due to air‑conditioning systems running longer and harder in Texas, some contractors advise replacing ducts every ten years rather than waiting 15 years; the general guideline is 10‑15 years depending on wear.
Can I repair leaky ductwork or does it have to be replaced?
Small leaks and minor corrosion can often be repaired, but heavily damaged or outdated ductwork should be fully replaced. If minor leaks are a result of aging we recommend replacing the HVAC duct system to improve the air quality, enhance home comfort and long term efficiency.
What duct materials are available and which is best?
New ducts may be made from galvanized steel, aluminum, fiberglass board or flexible plastic, each with different cost and performance characteristics
How do I know if my ducts are properly sealed?
Signs of leaks include visible cracks, loose connections or unexplained increases in energy bills; HVAC technicians may perform smoke tests to detect hidden leakage
What can I do to improve duct efficiency and indoor air quality?
Sealing leaks, insulating ductwork, optimizing the duct layout and reducing dust buildup will improve airflow and efficiency. Keeping ducts clean also prevents dust and contaminants from restricting airflow and raising energy use
