Does a new HVAC system include ductwork? A new HVAC system might include ductwork if the existing ducts are compatible and in good condition. Otherwise, new ductwork might be necessary.
What are the best AC ducts? Metal ducts (sheet metal, flexible aluminum) are common choices for AC systems due to durability and fire resistance.
Is there a shortage of ductwork? Supply chain issues can occasionally lead to shortages in HVAC materials, including ductwork.
How can I make my old ductwork more efficient? Sealing leaks, adding insulation, and proper maintenance can improve the efficiency of old ductwork.
Is it hard to replace ducts? Replacing ducts requires specialized knowledge and skills. It can be a challenging task for someone without HVAC experience.
Is replacing ductwork messy? Ductwork replacement can be messy due to dust and debris from the removal of old ducts. Contractors take steps to minimize mess.
How often should ductwork be cleaned? Ductwork cleaning frequency varies. Typically, every 3-5 years is recommended, but it depends on factors like indoor air quality and usage.
How long does flexible ductwork last? Flexible ductwork’s lifespan is around 10-15 years, but it can vary based on installation quality and usage.
What is the most efficient AC ducting? Well-insulated, properly sealed metal ducts tend to be more efficient for AC systems.
Is spiral ductwork more expensive than regular ductwork? Spiral ductwork can be more expensive due to its manufacturing process and aesthetic appeal.
Is a duct booster worth it? A duct booster can help improve airflow in certain cases, but it’s important to address underlying issues causing poor airflow.
Is it better to clean or replace air ducts? Cleaning can help improve indoor air quality, but if ducts are old, leaky, or inefficient, replacement might be a better long-term solution.
What are the benefits of duct replacement? Duct replacement can improve energy efficiency, indoor air quality, and comfort by eliminating leaks and improving airflow.
