6 HVAC Problems and How to Fix Them

Have you ever been called to a building where the air conditioner is running, but the occupants are still uncomfortable? In many cases, the HVAC equipment isn't actually broken. The real problem may be hidden somewhere else in the system. In this video, we'll explore six of the most common HVAC problems found in commercial and residential buildings and explain the root causes behind each one. You'll learn why evaporator coils freeze, how dirty condenser coils reduce efficiency, what causes airflow restrictions, why humidity problems occur even when temperatures seem normal, how short cycling damages equipment, and why energy consumption suddenly increases. Whether you're an HVAC technician, facility manager, building engineer, estimator, contractor, or simply someone who wants to better understand how HVAC systems work, this video will help you identify common problems before they become expensive failures. Topics Covered: ✔ Frozen Evaporator Coils ✔ Dirty Condenser Coils ✔ Airflow Problems ✔ High Indoor Humidity ✔ HVAC Short Cycling ✔ Excessive Energy Consumption ✔ Root Cause Analysis ✔ HVAC Troubleshooting Basics Understanding how airflow, refrigeration, heat transfer, humidity control, and system operation work together is the key to diagnosing HVAC problems correctly. 📚 Learn More at MEP Academy: https://mepacademy.com 🎓 Online HVAC, Plumbing & Electrical Courses: https://mepacademy.com/courses 📥 HVAC & Plumbing Estimating Spreadsheets: https://mepacademy.com/shop 👍 If you found this video helpful, please LIKE, SUBSCRIBE, and turn on notifications so you don't miss future HVAC training videos. #hvac #AirConditioning #HVACTroubleshooting #HVACTraining #CommercialHVAC #HVACTechnician #FacilityManagement #BuildingEngineering #HVACMaintenance #MechanicalEngineering 📘 WANT TO GO DEEPER?
