HVAC Troubleshooting Part 2

In another class from our training series from Polar Bear Air Conditioning, Bryan Orr presents Part 2 of HVAC Troubleshooting fundamentals. Learn about the critical relationship between suction pressure and evaporator temperature, liquid pressure and condensing temperature, and how subcooling indicates liquid stacking in the condenser. Bryan explains why common practices like running continuous fan operation can worsen humidity issues in humid climates, and shares practical diagnostic approaches including isolation diagnosis for electrical issues. This session includes valuable insights on delta T measurements, the impact of humidity on system performance, and how to properly diagnose transformer and fuse problems. Key topics: Temperature and pressure relationships Humidity effects on system performance Isolation diagnosis techniques Low voltage troubleshooting Delta T considerations in humid climates #HVAC #HVACtraining #Troubleshooting #HVACtech #hvacschool You can find more on Polar Bear Air Conditioning at their Youtube channel:    / @polarbearky   Buy your tickets or learn more about the 6th Annual HVACR Training Symposium at https://hvacrschool.com/symposium.
