Instructor Bryan Orr dives deep into the nitty gritty details of compression ratio in HVAC systems in this HVAC School video. He touches on the answers to the following questions: What exactly is the compression ratio? Why does it matter? How is it calculated, and what impacts it?

Bryan covers all of this and more using realworld troubleshooting stories and examples to reinforce key concepts. He examines compression ratio in different system types, from air conditioners to heat pumps to refrigeration. The class learns how condenser coil size, evaporator temperature, multistaging, and even airflow affect ratio.

Most importantly, Bryan shares tips for properly diagnosing and troubleshooting compression ratio problems in the field. What causes a low compression ratio? What are the consequences? How do you identify issues with the compressor, reversing valve, or metering device? The Kalos team gets crucial knowledge they can apply to every job.

HVAC professionals at any experience level will benefit from the information in this video. Join the class and take your understanding of compression ratio to the next level!
