Awesome quick reference👍
Really handy to have in the tool bag. Well made. I put a large key ring on them through the provided holes. Colour coded PT charts including the A2’s 👍

These Cards contain so much valuable information for both new and seasoned technicians. Straight and to the point, no fluff. I love it.

Essential HVAC info
Lots of important info packed into these 3 cards. Especially good for new techs or DIY'ers. Even pros will find something new and useful. PT charts are handy, although digital gauges have the database built-in. Cards are plastic, clearly printed both sides in color. I will be keeping mine in a zip-lok bag to prevent scratching in my toolbag. A good troubleshooting reference - worth the money!

Better than advertised
A must have for HVAC Technicians. The troubleshooting guide is an added bonus, but it’s nice to have some thing that I can put in my case with my gauges as a reference tool.
