Hello,
I have a central air/heat pump unit in my attic which cools the upstars portion of my home. There is a pair of copper lines which go to the fans unit outside. One is insulated and the other bare. I assume these are the coolant lines. When the A/C first starts running I hear the coolant running in these lines. I also hear a gurgling sound coming from the attic box blower unit. This is definetly coolant gurgling and increases in sound to that of a full boil. After a few minutes all of these sounds subside.
Are these noises normal? The coolant lines run inside of an interior wall down to the crawl space where they exit to the outside fan unit. I havent listened closely, but near as I can tell the larger unit which controls the lower level temp does not make these sound. That unit however is in the crawl space and not readily accessable.
Thanks
Matt
