Great Experience
“Great experience! Chris was amazing at everything. He did a thorough job diagnosing my plumbing issues and described various estimate options. He was not pushy for anything I wasn’t comfortable with. He completed the work efficiently and triple checked his work to ensure quality service.”
Knowledge, Professionalism & Dedication
“Miguel, HVAC technician from Cardinal Plumbing Heating & Air, came to my home to inspect the HVAC system and vents. I had recently bought the house and had no prior HVAC history, so I wanted to ensure everything was in good condition. Following the inspection, Miguel provided me with solid recommendations. His knowledge, professionalism, dedication to quality work, and comprehensive report gave me peace of mind. I was so impressed that I signed up for Cardinal’s $9.99 monthly service contract. “
Experienced, Comprehensive, and Very Courteous
“Cardinal just completed their routine customer care of the plumbing in our multilevel single family home. The lead plumber was experienced, comprehensive, and very courteous. He explained his findings and recommendations and gave practical advice without pushing costly improvements.

Cardinal clearly stakes their reputation on providing onsite expertise. This is why we continue to stick with Cardinal.”

Frequently Asked Questions About Air Duct Replacement
Knowing when your air duct system only requires simple repairs can save you time and money. Signs to look out for when a repair is needed include leaky air ducts, poorly insulated systems or imbalanced ductwork. Eventually, all air ducts will need replacement. The age of your air ducts and damage caused by smoke, water or rust are the most common causes for air duct system replacements.
The time it takes to replace air ducts in a house depends on the size of your home and the complexity of the duct system. Most residential jobs can be completed within one to two days. During our initial assessment, we’ll provide a more accurate timeline based on your specific situation.
At Cardinal Plumbing Heating & Air, we use a proven process to deliver top-quality ductwork replacement services. Here’s what you can expect when you work with our team:
- Inspection and Assessment: Our process begins with a thorough inspection of your current ductwork.
- Customized Ductwork Replacement Solutions: Once we’ve completed our assessment, we’ll create a customized plan to replace air ducts in your home.
- Expert Installation: Our experience will carefully install your new ducts, ensuring all connections are properly sealed to prevent air leaks and maximize efficiency.
- Post-Installation Testing and Support: After the air duct replacement is complete, we conduct a final round of testing to ensure everything is working as it should.
In some cases, it may be possible to replace just a damaged section of your ductwork rather than the entire system. However, if your ducts are outdated or the damage is extensive, a full ductwork replacement is often the most cost-effective solution.
Air duct replacement typically costs between $2,500 and $15,000, depending on the amount of ductwork being replaced, the number of runs, sizing requirements and duct accessibility. We provide an upfront flat-rate price before approved work begins.
