Compressor Noise transfering into home

I have a new Bryant A/C unit in a new home. You can hear a awfull vibration in the lines comming from the wall inside the house. The installers came out and could not figure out the noise and it's not loose lines in the wall.. They took readings and everything is OK.They got with Bryant, came back a week latter and zip tyed some hard rubber onto the outside lines and left. Now it's worse than before and I can't get ahold of them. I think the compressor is bad.... Made in China or something... but I am no expert. I need help in order to tell them what's wrong because I am getting the run around !!!!!

Thanks !!!!

    Thank you for your experenced insite! I watched the home being built from the ground up and I checked the lines before the Brick and Drywall went up. I had heard of these problems before so I was on the lookout. There are no vibration pads under the unit and it sits on a cement pad. There are 2 units and only one does this. I will contact the builder and see if he can get ahold of the installer at which time I will relay the great advise you gave me to them. There is a lot to be said of 45 years experence !!!! Thank you ! Jim

This can happen if the unit was not evacuated and there are non-condensables in the system. Sometimes a line rubs against a floor joist. The compresor can put out a high freqency hum thru the lines. Change compressor. Make sure they evacuate the system. The pressures can be OK when you take them but when the unit reaches a certain pressure it start the viabration. Does the unit have viabration pads nder unit. It can be fixed. I just listed some things I have run into over the last 45 years of service. Rus

I have just purchased and installed a Samsung AQ12FEN. A qualified Airconditioner company installed the unit. The slpit unit installation is a back to back configuration It replaced a 8 year old split...

This could be caused by an installation problem. The system could be severly overcharged, causing the compressor to load up and can cause a failure. i would start there. Is your intaller qualified to install these systems? (does he know what he is doing?)
I recommend, checking the refrigerant pressures first. You can also check the Polarity of the high voltage in to the outdoor unit. If the compressor is an Inverter Drive compressor, and the polarity is reversed, the compressor can run backwards causing the noise and eventual failure. To correct a polarity problem, simply remove the 2 high voltage wires that feed power to the outdoor unit from the board or contactor. Then reconnect those 2 wires, in the opposite position. (say you take loose from the unit and the Black wire is on the right side, and the white wire is on the left side. Simply swap sides, reconnect the Black wire on the left side, and the White wire on the right side.

Hope this helps,

If the compressor is not clicking on then the relay or the capacitor is defective. Remove the unit out if the compressor is not working and check the relay unit , if the contacts are good , the check or replace the capacitor.
If however the comprssor is not holding on , the current drain must be checked using a clamp tester . if high the compressor can be faulty and might need an overhaul.

Air conditioner is only 2 years old. Outdoor fan is not working. Air is circulating inside house but not cool. Bryant Legacy line Model No. 123R Help - seems too soon for the compressor to go bad. What...

You said the outdoor fan is not running, can you hear the compressor running? If you can hear the compressor running then start by checking the fan capacitor. If you can't hear the compressor, then check the breakers or fuses or disconnect. One of these should be located near the outside unit. If you look at the contactor you can see the contacts. When the unit is off they should not be touching, when it is on then the moveable contacts should be pulled down and touching the stationary contacts. You can get some on at the thermostat while you watch the contactor to see if it moves when they change the thermostat to call for a/c. Let me know what you find and I can give you more advice.

Condenser the compressor vibrates bad and then it shuts down code on board says high thermal cutoff

Hi, what is happening is the unit is shutting off on high head pressure from the sound of it. Bryant units are top of the line! What you need to do is shut the main power off to unit. I dont no if you have a split system 2-part with a indoor unit and outdoor unit or a package unit all in one. It really makes no difference. Go to the outdoor coil, which is the condenser coil. Take a good water hose and wash this coil very good all around and inside where the fan motor is. These units are made for outdoor use but don't spray directly on the controls. Be careful not to mash the fins with to much pressure.If the fan motor outside is running up to a good speed, this will take care of the high head pressure, I know for a fact. Let me know the out come. If by some reason it does not cure this, we will go into it further. I will be waiting to hear from you.

Noisy Bryant Air Conditioner with Puron Regrigerant Model 113A

Steve, From your description you may have some debris on the inside of your A\C line. When you install a split system there needs to be a filter drier installed to collect any excess solder\brazing material or any other solid or moisture contaminents. A miniscual piece will lodge in the metering device then sometimes push through go through the compressor and make another pass. Making horrendous noise and sometimes tripping the breaker. A drier is usually a blue cylinder on the smaller line right before the indoor coil attached to your heater. Some Techs put one by the outside unit. If you dont have a drier it may void your warranty.

Haier ESA 3185 AC won't cool; makes escalating loud vibrating noise near front panel/ filter

Have someone check the run capacitor of this unit. If the run capacitor is bad over shorted it can cause the unit to run and short cycle on a current overdraw. This makes for an electrical imbalance in the compressor motor. Next step is the compressor is faulty.

Loud as Hell

Is it installed in a window? Check to make sure it is installed correctly. usually there is a felt or foam strip that is used to dampen vibration when you place it in the window. It also acts as seal to keep outside air and bugs out. If you place your hand at various locations on the unit does the sound go away? If it does then you know it is a vibration problem. Just add new foam or re-adjust the foam or gasketing it already has. If that doesn't work then try to locate the source of the noise. Use a mechanics stethoscope or even a cardboard tube from paper towels will work. Once you have located the source then you can tell the store what the problem is when you take it back and get a new one. Cheap air conditioners are noisy. Some more than others, it's why they are cheap. But your problem does sound like it could be a product issue.
