Hello all I am about at my wits end....We had a 2 ton 14 seer Ruud heat pump installed at the end of last year. The biggest problem I am having is in heat mode when it goes into defrost it makes a loud almost helicoper sound for about 20-60 seconds, wakes you up that's for sure. When I have had the company that installed it come out I can never get it to do it for them and I even tried recording it. We have had a multitude of problems I believe mostly stemming from the company that installed it.

On 7/18/06 I purchased a 2 1/2 ton 13 seer AC and coil. The day it was installed I had to call for service as it was not working. The technician found a connection has failed to be made. Last year, when the unit was only 2 years old, it started to make an very loud noise that could be heard inside the house. When the technician came out, he said he could not hear any unusual noise. This year, now the unit is 3 years old, it started to make the same noise which keeps me awake when the air cu

We have a 2000 Winnebago Adventurer with basement air, "true air". Yesterday our AC unit started making a loud buzzing noise about every 90 seconds. Like maybe the second compressor was trying to start up and couldn't. We turned the AC off for awhile, and when we started it up again the noise started immediately. It buzzes for maybe 10 seconds. What can we try ? Should we leave it turned off ? It is over 100 degrees here in Texas and we need help fast!!! Thank you. Pam

I have a 10 SEER heat pump about 16 years old, yesterday I notice that the outside unit was making a loud click noise in the heating mode. It's very close to the defrost electrical curcuit board. The unit still was putting out heat inside but decided to turn off the unit and use the emerg. heating. What could that loud clicking sound be? concern, Gilbert


Depending on make and model sounds like a check valve clicking. It can sound like it is coming from that area. You say your unit is 16 years old. Honeywell did servey on unit 10 years and older and found out they loose 25% effeicency after 10 years. ... Air Conditioners

I recently got an Iron Cleer system; 3 tanks total. It is installed in a downstairs little utility room, with a door, along with the water tank/well pump. My problem is the compressor on top of the Iron-Cleer. Outside of nightly regeneration, it goes off 4 times a day for 10 minutes apiece. When it goes off, it is SO LOUD you can't hear TV that good upstairs; the firrst time it happened I jumped up on the second floor; didn't know WHAT the heck that loud noise was. Anyway, the only solution

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

I have an Amana PTAC that was just installed two weeks ago. I am starting hear a moderately loud warbling sound when it is in operation but not all the time.

Other times it goes all day without making this noise. I'm sure it does this when I'm away and I never know. This is only when the heat is on. Could the AC compressor be kicking on? If so, that's
