Understanding Your Ductwork

The air ducts in your home play a crucial role in circulating heated or cooled air from your HVAC system. Proper maintenance of your air ducts improves indoor air quality and ensures even distribution of air, preventing the formation of hot and cold spots.

Signs It’s Time to Replace Your Ductwork

  1. Increasing Energy Bills: If you notice a sudden spike in your utility bills, your duct system might be to blame. Leaky or poorly insulated ducts force your HVAC system to work harder, leading to high energy bills.
  2. Poor Air Quality or Allergies: If your indoor air quality is deteriorating or if allergies are more frequent, it might be time for an air duct replacement. Old ductwork can accumulate dust, allergens, and other contaminants, affecting your air quality.
  3. Uneven Heating and Cooling: Cold spots or uneven temperature distribution could signify faulty air ducts. Properly functioning ductwork should distribute air evenly across your home.

The Age Factor: When to Replace Air Ducts Based on Lifespan

The typical lifespan of ductwork is around 15-20 years. Beyond this, your air ducts may become less efficient, impacting your HVAC system’s performance. In general, it might be time for a duct replacement if your system is nearing or has surpassed this age range.

Cost Considerations: Is It Time to Replace or Repair Your Ductwork?

Sometimes, an air conditioning repair or heating repair can extend the life of your ductwork. However, if the repair costs start nearing the price of new ductwork, it may be more beneficial to opt for a full air duct replacement.
