HVAC Quick Reference Cards for Refrigerant Charging and Troubleshooting!

In this HVAC Training Video, I Explain how our HVAC Quick Reference Cards can be used while Refrigerant Charging and Troubleshooting! I go over the 6 sides of the 3 cards to discuss what is included. These cards are made from flexible polystyrene and are 5.625" high by 8.85" wide. These polystyrene cards compliment the book and can be used as an easy and quick reference in the field!
