In reply to comment: You're obviously NOT an engineer (see in situ)

you and mad23 have a LOT in common......

you both talk down to me....

so, does the "cold" pipe on your A/C really have the heat in it?
and if so, care to try and explain that?
hint,
it has to do with latent heat of vaporization. (that would be the A/CR part of HVACTech)

combustion is a way more interesting topic for me.
what do you know about combustion? (that would be the H in HVACTECH)

are you both sockpuppets?

please notice, we have not even begun to speak of the "V" in HVACTech

and without knowledge of it....

I would be a HACTech
