Always go by your subcooling to check charge (superheat will vary based on current load). A sight glass will flash sometimes at half capacity, it will also flash at first when a system has been off...

So. I've never seen this before, and hopefully never will again.
I began a maintenance on a 1 year old BAC closed loop cooling tower, upon opening it up I was taken back by what I thought was a...

Thank you for the info...

whats a "good" vacuum? and do you know this because he told you or you witnessed it? thats a blocked drier not a carrier issue. A good vacuum, if any at all was pulled. Either that or it was an...

Ok, I see now, I haven't seen those Eaton style high flow valves before, interesting.....appreciate the information....I am amazed though that the tool for that is $500. thanks

No, its ok, you didnt read the post right. Someone had come out saying the coil needed replaced because there was a restriction "in" the system, condensor side. But what I found was there was only a...

Whoever told you this doesnt know what they're talking about, try $35 made by JB, I got some .com stock I wanna sell ya

Ok, I'm confused, just to see if were on the same page.....all the refrigerant leaked out of this "schraeder port" well if this was a typical schraeder port then you could get this at any supply...

Funny story about that, had a customer came to me wanting a second opinion/quote on replacing her 10 ton rtpu. Said she had a company come out and told her the condenser coil was "restricted", and...

You shouldn't need a new coil, just the headers with the orifices that come off the header. Also, confused with the diagnosis, you say the bottom of the coil wasnt getting cold, then you said you...

This may not be conventional, but we had a system with a couple of chilled water coils had burst due to the unit being turned off and OA still coming in, one of the suggestions was to fill it with...

Oh thats my bad then, I've been told it's a phase out of the manufacturing of r-22 all together by 2010. My apologies.......bad information

I've never heard it talked about much on here, but I think its a good conversation piece.

How heavily do you think the complete phase out of r-22 in 3 years is going to affect our industry. I mean...

Just put one in the other day, the capacitors blew in them, found out from the office that this is the third one put in in 4 years. The motor took this one out, a 20hp internally shorted, it must...

Anyone here have problems with Yaskawa VFD's, specifically the P7??

He's asking how to use his meter and your going to tell him to Meg out a motor??

Anyways,
If your testing a compressor for example and your going between r s and c, if your meter reads 'OL' or...

Thanks Busta thats a good site.....another question, the VFD that blew today is a Yaskawa P7, it's was only a year old.....would these capacitors have contained PCB's in them? Not sure on the EPA's...
