The refrigerant line in the wall of my guest bathroom running from the Lennox A/c condensor outside makes a loud buzzing noise when it is running. The supervisor of installation of the original installation company examined the unit thoroughly outside and up in the crawl space where the line runs and says the loud, irritating noise is normal. He claims that his unit makes the same noise in his house and that I am hearing the normal noise of the outside unit running inside the house. He explained
It may just be a loud condensor, otherwise, it could be a vibration from the unit housing and the noise carries. You could always replace the relay and see if it helps any. Also check unit pressure with pressure guage to make sure it is not over pump ... Air Conditioners
My recently May 3rd, 2010 purchased LG LWHD1009R Air Conditioner runs very well and cools great. Noise is not bad at lowest fan setting which is all I need really. My only complaint is the rattle buzzing type noise coming from the Air Intake or the Inlet Grille in the front of the AC. When you lower it the noise and rattle stop and the AC keeps running great. When I put it back up and connect both sides the rattle returns. I notice that if I put it back up but only connect one of the 2 prongs

I have a new furnace with a humidifier. Both work fine. The trouble is, the water running through the hose to the drain makes a LOUD dripping noise when it runs into the drain. Is there some way to stop the noise besides turning everything off..I have of tying a string to the hose and then the water will run down the string, but I am afraid the string might break and help clog the drain. any suggestions
Not seeing exactly what you have. I am guessing...does the humidifier have a trap on it coming out of the furnace?. Is this some type of over flow from the humidifier? If so...\015\012\015\012 I would suggest run ... Air Conditioners
I have new Samsung 1.5 Ton Window AC ( around one month old). Whenever AC is switched on in FAN or Cool mode the AC (probably FAn motor) make irritating Humming Noise. The noise slightly reduces after awhile. The noise level reduces when lower Fan speed is selected. This problem was not present in first few days of operation. Whether Compressor is on or off does not make any change in noise level. Noise level is same when AC is run in fan mode as well. We have contacted the manufacturer
It is possible that your AC is not getting the right voltage or frequency and hence is trying to scavenge in gettting the current. It will be good if you can check on the mains voltage or on the wiring for a good 15 amp supply line. If there is any r ... Maytag M6Q10F2A Air Conditioner
I have a Carrier Model# FA4BNF048, It just started making rattling noise and a thump sound like a car intake, the system is still cooling fine, its just the noise that is bothering us. I managed to get the cover off to listen carefully to the noise, that seems to be coming from the blower motor, I took it of with a few just bolts and wire diconnects, to ensure there were no loose parts in there, which I did not see or felt any. The system seems to be cooling still, but the noise after the au
Hi\015\012\015\012If your air conditioner is making a rattling noise, your fan is probably loose. Open it up and tighten the screw that is located in the center of the fan. You can also try a piece of plywood or Plexiglas that sits betwee ... Air Conditioners
A) I am trying to obtain a manual for a model #HWR12XC6-RB air conditioner. Can you send me one via email? B) Although it seem to run, the compressor only seems to run for a minute or two before shutting down for a time. Then it restarts. The temperature display seems to decrease while the compressor is running, and rises again when it is not running. The temperature never seems to aproach the set temperature. C) There are two types of noise I wasn't expecting. One seems to be a kind of klunking

1996 Coleman Model 7333C8876. Have 2 units on our Motor Home one day it was hot so I had both units running controlled by a Electronic Climate Control system.

The fan will not run on high and you can hear a slight noise coming from the unit. But the fan will not run on high.

I have a whirlpool quiet miser, ACE082XSO that is cooling fine, but makes quite a lot of tinnie rattling noise when I listen to it run on the outside of our bedroom. is there a fix for this noise problem and/or is there a place to purchase a new unit that will fit into this through-the-wall case? i'm suspicious that the unit is old and may fail soon.
Normally a sound like this is vibration or the fan making contact with the casing. If you pick up on the unit a press on it in different places and the sound goes away it i vibration. If its the fan there will be evidence on the edges of the fan blad ... Whirlpool Air Conditioners

I noticed some straining noise coming from my a/c unit today. The fan on top of the condenser runs fine but as soon as the compressor tries to kick on the fan stops for a split second and you get a kind of surging noise from the condenser unit. Then the fans kicks back on, the the process repeats itself every couple of minutes. Meanwhile no cold air is being produced inside the house. Any ideas?

Have a 5ton straight cool ac system. It's a Payne puron split sytem. metering device,txv. It will run for about 5 miutes during that time u can feel some cool back on the suction line. after that run time it will start to make a hissing noise. Over amp and shut off on internal overload. Any suggestions? Complete system is brand new and was put in around November.
Brand new systems won't require cleaning. Debris could get trapped inside the internal parts/lineset and break loose and cause a blockage which could cause high head pressure, hissing and over amp. It is possible that the charge requires readjustment ... Air Conditioners

I. The outdoor heat-exchanger fan runs at a low speed (with a humming noise), when the home temperature is below the set-point. ii. When home temp. in high, fan runs at full speed, like normal. iii. When A/C breaker is shutoff (in main switchboard), the fan stops. Need help diagnose the problem.
It could also be the contactor; basically an electrically-controlled switch that in turn controls the compressor and the condenser fan. If it's a 220 volt motor, and one side of the contactor has very high resistance, it'll be seeing 110 volts inste ... Air Conditioners

Turned on AC was running fine. 30 minutes later began to hear a strange noise. Opened AC/Furnance closet & heard a sound best described as air letting out of a tire. It seemed to be coming from copper pipe. Minute later sound stopped & air was suddenly hot. As if AC was turned on fan not cold. Went outside & neither fan nor motor was running. Turned fan manually. Ran for about a minute then stopped. Outside unit was making what could best be described as a buzzing sound.
