Ductwork Replacement & Repair in St. Louis

Providing Duct Design & Fabrication for Maximum Efficiency

Although they are essentially static, non-moving components, the air ducts in a home are critical to the performance of an HVAC system. Ducts that are damaged, loose or poorly-insulated can waste up to 40 percent of the green used for heating and cooling, while ducts that are undersized can restrict airflow, making the HVAC system run inefficiently, and ducts that are oversize may not cool or heat effectively. If your ducts are not properly sized or have major damage, it may be time to consider duct replacement.

At Classic Aire Care, our HVAC professionals can design, fabricate and install a duct system that will meet the heating and cooling needs of your home, as well as your HVAC system. Since 1926, our team has been providing quality heating, air conditioning, plumbing, and home comfort services to both residential and commercial customers throughout the St. Louis Area. Our technicians are NATE certified, follow all ACCA procedures, and are extensively experienced with all common types of heating and cooling systems.

Common Duct Problems in St. Louis Homes

As they heat and cool, ducts will expand and contract, leading to metal fatigue, wear and loosened connections. Over many years, this process can start causing duct failures, especially in combination with extraneous forces, such as a poor initial installation. Some common duct problems include:

  • Damaged or missing insulation
  • Loose fasteners
  • Loose joints
  • Missing foil tape or mastic at joints
  • Improper support along the duct’s length
  • Crushing or puncturing from poor installation or careless remodeling
  • Improper use or installation of flexible ducts
  • Contamination with mold, bacteria, or pest droppings
  • Undersized or oversized ducts

To determine if your ducts have any of these problems, contact us today for an inspection!

Immediate response. Had new system I stalled within 48 hours of first contact. All staff members were professional, courteous and very knowledgeable. Everything was perfect. They just came out this week to make sure our ac was good to go due to winter install. No cost…

An extremely professional company, from the person who sold us the unit to the gentlemen who installed the unit. They were on time and completed the work in the time they said, and cleaned up. We will use this company again. Highly recommend them.
