Hmmm. I seem to see alot of people who aren't qualified to do this kind of work giving alot of hard working people issues (can't say "hack" because i'll get in trouble again!) It gets me frustated in many ways.
Thank you Swariz. We contracted a reputable company for the install or thought we did. I took the first pro's advice after they sent 3 "hacks" and requested a supervisor. He is here as I type so we will see...... Connie
To ConnieB: your "tech" is not a tech, but a hack! Get someone out there that has a clue (would NEVER bypass a high pressure switch, for one...). To Matt: your terminology makes you sound like a DIY'er, and I just recently was in an accelerated training environment and we used the correct terminology there at all times. If you are that close to your "associates", you should know that switches apply to electrical (primarily) and "valves" apply to fluid or vapor movement. I have "valves" on the end of some of my hoses, and LLF's on the rest. There are no switches involved in a guage manifold (unless maybe a digital one, but don't have one yet). If pressures are "maxxing out" on the guages, they should have taught you in troubleshooting 101 what the cause would be. I am also a student, and just this year got my 608 universdal and 609 certs. but have been on the warmer end of hvac for about 15 years on and off. I don't work in the trades , but as a building "engineer" for a branch of the govt, and am receiving some excellent training from them. I have read this post in it's entirety, and you should go back and read markettech's ( http://hvac-talk.com/vbb/showpost.ph...74&postcount=1 ) post about 4 more times. I am also working on getting my post count up to apply for pro membership. These guys here really do know their stuff, but I appreciate them not just giving it out to every DIY'er that comes along. Respect them, do what they say, go pro, then your questions will be answered.
Unit If the tech's name is "Unit" then yes you might have a bad unit. You might want a second look at this new install.

The not even a week later (last night) the pressure went to 160/550 according to the installer the high pressure switch went out on it. He said he reset it to 150/375 and by passed the switch. And will have to come out tomorrow and install a new switch. Would it be possible for someone to tell me why a switch would go bad on a brand new unit not even a month old. I couldn't really understand (language barrier, don't speak spanglish) but it sounded like the installer told me that the air outside was TOO HOT so the compressor switched off??? It was late so I couldn't get anyone from the office (or manager) on the phone. Just trying to figure out if we may have a bad unit. Thanks for any input. Could be a multitude of things. If you do not have faith in the tech, call them and get a supervisor out.

Sounds like you have landed yourself a hack. Good luck.

is that when you turn on the switch????????????? Originally Posted by fotofx Let me point something out... Most analog gauges will read up to 500 psi on the high side. If the compressor was on thermal the pressures would equalize. Meaning that both low and high would have to be over 500. Unless this R22 system is Satan's I don't think he would have the required temp to equalize at over 500.
