How to diagnose running water sounds in refrigerant piping at the air conditioner, heat pump, or refrigerator What causes running water sounds or burbling or gurgling noises heard in the refrigerant piping or tubing in an air conditioning or heat pump system Gurgling noises in HVAC or refrigeration equipment is often traced to an improper refrigerant charge, refrigerant gases in the liquid refrigerant line.

Reader Question I have a 4 ton heat pump that hisses when it shuts down in 4. The frig. lines run in the wall near bedroom. Sounds like freon running back to or from compressor, Only in heat cycle. Question Just this morning I noticed when my heat unitpump was running it sound as if water was draining through pipes. The out side connections to the pumpinside unit run over head in my laundry room So far theres been no other issues. Any idea what this could be Should I be concerned Once the heat shuts off this draining sound quits. Ruth 12. 51. 2Question I live in a 1st floor apartment. When the AC of the resident on the 2nd floor turns on, there is a sound like cascading water in about 1 minute intervals and lasts for 1. This continues under the unit turns off. Alcatel Omnipcx Office Small Software Download here. I have been told by maintenance that its the freon rushing through the pipe and that its normal. I have lived in several apartments and have never heard this before. Invariably, for some reason, condenser units are always just outside bedroom windows. So, my question is, is this indeed normal Anonymous 2. Reply causes of running water, bubbling sounds or burbling gurgling noises in HVAC equipment. Under charged refrigerant or a problem originating at the condensercompressor might cause running water sounds in the high pressure refrigerant line on an HVACR system, though usually complaints are traced to these second condition we state next. See UNDER CHARGED REFRIGERANT, EFFECTS for more details. Visual Basic 6.0 Video Tutorial 40 Videos. Bubbling in the refrigerant piping is discussed at REFRIGERANT LEAK REPAIR and may indicate a refrigerant leak, though bubbling sounds on split systems at the indoor wall unit may be normal for some products. Refrigerant floodback noise can occur at any time not just at startup. Floodback noises are likely to be heard in the suction line of the HVACR system. Running water sounds, bubbling, burbling, gurgling noises in the air conditioning or refrigeration system suction line may be due to liquid refrigerant in the suction line on the low pressure side of the system. Floodback happens in the suction line when liquid refrigerant is burbling along where we expect to find only refrigerant in a gas state. That might be caused by a problem with the refrigerant metering device or by an HVACR system that has been overcharged too much refrigerant has been added to the system. Watch out. A severely overcharged system compressor can have floodback when running and this can lead to compressor failure from oil being flushed from compressor or broken valves in reciprocal compressors. Tommy 11. 52. 01. Equalizing refrigerant pressures at shut down or at a heat pump when the reversing valve operates or when the system reverses direction for defrost during a heating cycle can cause whooshing sounds that are normal. But at this point you may also hear gurgling or bubbling sounds in that case check for low refrigerant. Ruth,Also check for running water sounds traced to drain piping that receives air conditioner or heat pump condensate from a condensate pump. Level Up Conqueror Of All Worlds Game. Because the condensate pump only runs when its reservoir is filled, the pump on off cycle will be irregular, but the pump may be sending water into a building drain that, because of its material plastic and location not through sound insulated space could show up as a running water or gurgling sound. Anonymous Normal to some techs is problem to others it depends on exactly whats going on. For example, insufficient charge of refrigerant or air contaminants in the system can cause one to hear refrigerant burbling along in the high pressure line where normally the line is full and silent. If my guess is right, ultimately the 2nd floor resident will have no cooling and the system will have to be repaired properly. Reader follow up evacuate and re charge the system with refrigerant Question. Would evacuating and recharging the system be a course of actionAnd is this an expensive process Or is the way to look at it do this and you wont have to replace the compressorReply fix the refrigerant leak, install the factory specified volume of refrigerant charge. Yes. And yes. But the cost to properly charge an HVACR system is certainly significantly less than wholesale replacement of the compressorcondenser. Im unclear on why someone has suggested that compressor replacement is needed for this problem. Keep in mind that anybody diagnosing a complex system by e text is unable to see onsite clues that would shout loudly to any competent expert who is on site. Assuring that the system is properly charged is a step techs take to address the running water sound problem were discussing as would be appropriate for a low refrigerant charge for any reason. Some HVACR systems include a sight glass on the refrigerant line that allows the tech to actually see the refrigerant gas bubbles but most residential systems dont. Returning to the question of refrigerant charge vs. A tech whos trying to guess at the refrigerant charge on a running system will measure temperatures on the high and low lines, but all that tells you is that there is enough refrigerant to cool the coil, not that the full measured charge called for by the manufacturer has been placed into the system. Its an expensive and low quality but very common repair to simply add enough refrigerant to get the system cooling. That is very likely to be less than the charge volume specified by the manufacturer and profitable for the service company. If there is an ongoing refrigerant leak, the system will ultimately stop cooling again, perhaps first icing the coil then stopping cooling entirely. A proper and best repair when the refrigerant charge is low is to find and fix the refrigerant leak, then place a proper charge in the system, charging with the quantity of refrigerant specified by the manufacturer. Most HVACR systems other than very small ones include a receiver that buffers a charge of refrigerant that is larger than simply the bare minimum needed to fill the tubing and compressor. Question running fluid noise in the pipes after the fan stops refrigeration pipe gurgling soundAug 3. The air sending unit continues to make a running fluid noise in the pipes after the fan shuts. The weird thing is that a loud noise will stop the running water noise in the air sending unit. It makes no sense.
