ChipR Posted February 27, 2004 Author Report Share Posted February 27, 2004 I am just happy to have received some attention. I have been a carpenter building residential homes for the past 25 years. I have been looking at the HP's and now recognize the reversing valve. However, I have only seen a small liquid line and the large gas line, never have I seen both of them the same size. I have seen 3 lines, 2 small and one large. One of the small ones had a small barrel looking thing attached. I would like somebody to explain the purpose of that device.

mcramer Posted February 27, 2004 Report Share Posted February 27, 2004 The lines on a heat pump will be the same as an air conditioner. One large. One small. The barrel thingy is a drier. It's put on when the system is opened, like to put in a new compressor. It filters out contaminants. Look at the ends. They rust and leak. If you see oil on the rust, that's a leak.

Jeff Hardesty Posted March 10, 2004 Report Share Posted March 10, 2004 Originally posted by ChipR The house was warm and cozy. It had electric heat. It was difficult to tell if it was a heat pump or a air conditioner since the label was faded. I would like to now how I can tell the differance between heat pumps and air conditioners when it can't be read on the label? Chip Chip, Look inside the compressor (outside unit). A heat pump will have a visible reversing valve that will look like a solenoide with refrigerant piped into and out of it and conducors that control direction.
