Iv had that happen before made the whole system leak a lot of water and glad I told my coworker like hey just bear with me and open that coil door and glad I did

Nice. Very good Info Dude. 👍🏻👌🏻✌🏻🖖🏻❄️🔥 Subcool 10, chart says 10, tech adds refrigerant because suction is low. Uh-oh we got ourselves a parts changer. R410a I’m not sorry it’s going away. 410a suck ball. I hope next one is lower pressure like R22. But no, now mildly flammable. A lot of techs don’t flow nitro for braze, now you have to or 💥 KaBoom🔥

Subcool shows condenser, subcool shows indoor side of the system. Always measure both , it's two separate readings.

I've seen issues with A coils with the point of the A towards the furnace causing high temp cut out during heat mode. The top of the A coil blocks alot of air as soon as it leaves the furnace. I know some of those say bi-flow but got to be careful on that.

Good Catch

Thank you for sharing, you have probably saved me an exuberant amount of money from those money hungry guys!

Time for a new unit lol
