But more often than not, the problem is in the ducts. Crushed, disconnected, undersized, or just plain missing \u2014 ducts are one of the biggest sources of inefficiency in any home. And I always take a look. I Check That Every Room Has a Source of Heating or Cooling During every inspection, I walk every room, closet, and converted garage looking for one thing: a supply register. There should be at least one heat or cooling source in every room that\u2019s considered \u201chabitable space.\u201d If there isn\u2019t? That\u2019s a big deal. The room may not heat or cool evenly\u2014or may not be compliant for its intended use (like a bedroom or office). Thermal Cameras Help Spot Hidden Problems I love using my thermal camera when checking ducted systems. If the HVAC is running, the camera can show me which vents are putting out air\u2014and which aren\u2019t. Sometimes the difference is obvious: one room is ice cold, the other is lukewarm. That usually means a disconnected or leaking duct, even if the attic or crawlspace hides it well. What I\u2019m Looking For\u2014And What I\u2019m Not \u2705 I\u2019m looking for: missing supply vents, airflow consistency, disconnected or damaged ducts, obvious airflow restriction, poor attic\/crawl insulation on ductwork. \u274c I\u2019m not looking to: cut open ceilings, pressure test the system, or run CFM airflow diagnostics. That\u2019s for ducting specialists or HVAC techs. Common Duct Red Flags I See All the Time Disconnected ducts \u2013 Usually found in attics or crawlspaces. Air ends up in the wrong place (like your attic). Crushed or compressed flex ducts \u2013 Poor installation or too much storage weight can restrict airflow. No return air path \u2013 Without a way for air to get back to the HVAC system, airflow suffers, and pressure builds. Dirty or moldy vents \u2013 Not just gross\u2014can indicate a filter issue, moisture problem, or lack of cleaning. How This Affects Comfort & Utility Bills If your ducts are inefficient, everything else suffers. Your HVAC system works harder. Your rooms stay uneven. And your bills go up. That\u2019s why I include duct issues in my report. Even if the system itself works fine, poor distribution undermines the whole setup. FAQs: Ducts, Vents & Airflow Should every room have a vent? Yes. Every habitable room should have a source of heating or cooling. Missing vents can affect comfort, resale value, and compliance. Can you tell if a duct is leaking? Sometimes. If there\u2019s no airflow at a vent and no visible damage, I may use a thermal camera to look for signs of heat or cooling loss behind the wall or ceiling. For exact location or pressure testing, you\u2019d need an HVAC pro. Do you check ductwork in the attic or crawlspace? Yes\u2014if safely accessible. I look for disconnected runs, insulation issues, or physical damage. I don\u2019t open sealed or inaccessible spaces. Do you test airflow pressure? No. That requires specialized duct testing tools. I use visual inspection and thermal imaging to document performance concerns. \u2192 Next up: Post 20: Water Heaters \u2014 What We Inspect (and What We Don\u2019t) \u2190 Previously: Post 18: Cooling Systems \u2014 Testing, Limitations, and What\u2019s in Scope Curious what it\u2019s like to schedule your own home inspection with us?","datePublished":"2025-07-02","dateModified":"2025-07-02","author":{"@type":"Person","@id":"https:\/\/homeinspectionsovercoffee.com\/author\/curtis\/#Person","name":"Kloc Curtis","url":"https:\/\/homeinspectionsovercoffee.com\/author\/curtis\/","identifier":6,"description":"Curtis Kloc is a U.S. Navy veteran and seasoned entrepreneur with over two decades of experience in business development, inspections, and technical systems.
