HOMEOWNER CRIES FOR HELP...

QUESTION:
When insulating an expansion valve bulb after securing to the suction line, anyone know if there's a critical way to insulate it?

Do I just wrap them both together, or try to cover as much copper as possible on each without wrapping in between the two?

Maybe it doesn't matter as long as you've insulated? I've tried to cover as much as the copper as I can without separating the two with insulation where they meet, but was wondering if I could be interfering with the temperature sensing.

Maybe I am over-thinking this?

ANSWER: Sounds like it is in the right position and yeah you are probably over thinking it, if you just wrap it with foam tape or over wrap it with a larger piece of pipe insulation you should be fine.

You are just trying to keep the temperature of the ambient air from interfering with the pipe temperature the bulb is sensing.

Hope that helps.
