Ensuring your Air Handler Unit (AHU) is installed correctly is critical for optimal performance, energy efficiency, and indoor air quality. Even minor installation mistakes can cause airflow issues, energy penalties, noise, vibration, or premature equipment failure. To help building managers, engineers, and facility teams quickly gather installation data, CFN-HVAC offers a free online Air Handler Installation Check-Up Form . This tool allows you to collect essential information about your AHU installation, including: Project details and client information Installation location, access, and vibration isolation Ductwork, airflow, and coil setup Filtration, condensate drainage, and control systems Operational observations and photo evidence Once submitted, the data can be analyzed by an HVAC professional for a comprehensive installation assessment. This tool does not replace a professional audit but ensures you have all the critical information ready for a paid review. Use the Free Tool ...

By Charles Nehme 80 pages • Professional & Technical • $35.26 on Google Play ( Google Play ) In a world where energy efficiency and environmental stewardship are no longer optional, Heat Recovery From All Processes stands out as a practical, engineer‑focused guide to harnessing energy that’s traditionally wasted in everyday systems. ( Google Play ) 🌍 The Big Idea: Turn Waste Into Value Every building, industrial facility, and building service system generates heat — but most of it simply escapes into the atmosphere. Whether it’s warm exhaust from a kitchen, heat from a laundry unit, server room cooling losses, or industrial exhaust streams, this wasted thermal energy represents a huge, under‑utilized opportunity. ( Google Play ) Charles Nehme’s book tackles this challenge head‑on. Instead of letting process heat escape, this guide shows how engineers and designers can capture, channel, and reuse it — reducing energy bills, lowering carbon emissions, and improving system p...
