Bryan, Thanks very much for making these podcast. I know it take a lot of your time but you are changing the hvac thought pattern one podcast at a time.
This is awesome stuff. A lot of these videos are somewhat remedial, which is not a bad thing. I always pick up something I didn’t know. But this is a very advanced discussion, I think. Very good listen for in between calls are with your coffee in the morning. Great job, thank you for doing this.
I have a 3 year old ameristar system giving problems. On ab90+ degree day, it wont keep up. 2 ton heat pump 14 seer brand new install about 1000 sq ft old house. 1960s about. Suction pressure was up around 170, head pressure like 240 or so. Its anpiston, so cant be bad txv. Tech said compressor was bad cuz it was pulling 4.6 amps, rated for 13.5. Replaced compressor, now pressure is better looking, still not keeping up. I'm thinking the reversing valve solenoid isn't going all the way over, thus freon bleeding thru. Any other suggestions?
My thoughts on the fully closed TXV. In A/C never happen as part of normal operations but in the other hand on refrigeration it will happen and that's were it is critical a good working TXV superheat. Just a thought 🤔
I work at an equipment manufacturer and I've probably brazed in hundreds of TXVs on these units. I can tell you that some brazers do better jobs than others and I worry about damaged txvs.

I listened to this podcast four times to grasp what Jamie said but didn’t click yet! Very interesting infos. Thanks Bryan .

This was very interesting, thanks
What would the symptoms of a plugged distributor line be?
Even if the coil is starting to freeze up will it still have a low to normal superheat?
Freezing up due to low air flow
Dang Brian, I need pictures.
hey quick question can i use stay brite soft solder to install txv or tev?
Staybrite 8 is often used although I don’t
I was taught to use staybrie # 8 when installing a TXV
How long have you used #8 staybrite ,have you experienced any issues ? all my peers used for 40 plus years they love it.
Learned alot
Nice!
Normal SC 10, 3SH Normal pressures. WHY IS NOT 10-15 SH?
Back in the day manufatures used Silver wire on txv
I work at an equipment manufacturer and I've probably brazed in hundreds of TXVs on these units. I can tell you that some brazers do better jobs than others and I worry about damaged txvs.
I think using silver is probably smarter.
Man.... this guy sounds just like Christian Slater, don't you think???
