This is an ongoing clash amongst myself and some of my coworkers. I believe gauges should be on every time and one manager insisted if everything else checks out there is no need. I can assure you...

So for clarity, your purging vapor through your charging hose when you hook up, then bleeding your liquid side/charging hose back Into the suction side when your finished?

I'm really not trying to give you a hard time personally, as I'm sure many guys do this. As its being explained, I'm just really having a hard time digesting this as being "according to best...

So are you filling it with liquid also before sucking it back in through the suction side?

Ok... I've always had one question regarding bleeding over like that. So, I've hooked up, my low and high side are now pressurized. I close the ball valve on my liquid hose and let it pull back into...

Since I would only be able to afford one for now, then how do you address dealing with multiple refrigerants without cross contamination? Do I have to nitrogen purge them every time? Use different...

I was actually looking at an SMAN4 manifold today as well. So then whats the procedure when servicing 410/22 units with one manifold and hoses? Isn't there concerns of cross contamination?...

Those of you who already own an STA-2, I've been considering buying one for accurately measuring residential total CFM. Would you consider it sufficient and accurate at doing so? Thanks.

Alright, thanks Chops. I'll look further into it.

I registered for some upcoming seminars with RSES. I was also looking at their memberships. Could you help me understand what I'm getting by such a high cost of membership if you are a member? Feel...

Thanks.

Fair enough. Where could I find the best practices your citing to learn more?

Fellas, this may sound like a dumb question, forgive me. I've been considering the SMAN4 but how do you use one manifold/hose set with the various refrigerants and not cross contaminant? Does that...

I also have been using the hs36 for the last couple years and love it. I also use many of the various head attachments and have really enjoyed such versatility of the meter. If it broke I would...

I have also seen a fan run this way due to shorted compressor windings... I'd guess, with the info we have, thats your issue or you have power "trickling" somewhere and finding its way in that fan...

Forgive me, I just realized I missed that water was running out. Sounds like you have unconditioned air entering the unit as a possibility. You should call your local reputable HVAC guys and have it...

Just curious, if you had no outward signs of condensation, why would you otherwise go inside of the air handler?

A good service tech can apply what he knows and also do an install. He will be slower then a seasoned installer and typically more anal about the thoroughness of the install. In my experience, every...

Coincidentally, I also started another thread on this same subject today. I also confirmed today with both trane and carrier, if this stuff or dye is found in a system, it voids any warranty.

My...

Am I the only on who feels like a lot of these responses are trying to be "politically correct"?

So long as they have no affiliation with my employer, I would go do it myself. I own all of my tools and would go in my vehicle, on my time and purchase my own parts. Side work and my employer must...

Exactly! The irony in it all is the folks who are in support of performing tune ups with these half **s practices are the same ones who feel a tune up is ripping people off! Ironic isn't it?!

But that's the point, you don't know if its working properly otherwise. The only way you can know whats occurring inside the line set and coils is to observe your SH and SC, which require hooking up...

@ mgenius33, I would agree. There seems to be a strong "anti-business" sentiment throughout out this thread. I emphasized doing things with integrity many times so wont revisit that but asked some of...
