A range hood can run loudly and still fail to capture smoke. Use this symptom-first diagnostic sequence to separate poor capture from weak airflow before cleaning, repairing, redesigning, or replacing the hood.
Range Hood Height Above Stove: A Practical Mounting Guide
Mounting a range hood too high can weaken capture, while mounting it too low can create clearance, heat, and usability problems. This guide shows how to find the permitted height using the hood manual, cooking-appliance instructions, and project-specific requirements.
Range Hood Makeup Air: 7 Critical Rules Beyond 400 CFM
A range hood above 400 CFM does not create the same makeup-air requirement in every house or jurisdiction. Learn how exhaust capacity, combustion appliances, pressure balance, local code, and makeup-air design fit together before installation.
Range Hood Duct Size: Diameter, Length and Elbows Explained
A powerful range hood can still perform poorly when the duct behind it is too small, too restrictive, or badly routed. Learn how to verify diameter, material, elbows, route length, and outdoor termination before the installation becomes expensive to change.
How Many CFM Does a Range Hood Need? A Practical Sizing Guide
A bigger CFM number does not automatically make a better range hood. Learn how to size kitchen ventilation using hood width, placement, capture, ducting, noise, and makeup-air checks.
