Question about Haier Mechanical Air Conditioner HWF05XC7

Loud as Hell

Just got this new ac unit. IT does this weird buzzing noise and is so loud that it repeatedly wakes me up during the night. It only does this when the ac is on, not the fan. I can't sleep with ear plugs in, so that's not an option. Can I fix this? Is this normal? I've never heard an air conditioner so loud.

Re: Loud as Hell

As u said the noise comes when the unit at cool mode, it is clear that the unit makes vibration when compressor is on

I belive that the compressor is fitted with a Rotary compressor which makes more vibration then recip with a jerk.

The noise which is a hissing noise is coming from compressor and from the Tube -discharge line .

pl chk the tube are not touching anywhere, if touching pl clear it by pressing with hand slowly .
Add a weight (rubber) on the discharge to arrest vibrations

this will solve the problem of noise as the vibration.

Re: 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.

New A/C Unit makes loud noise when it starts up

It shouldn't be too loud. You don't explain where the noise is coming from? The air handler/furnace or the outdoor unit.

Buzzing Refrigerant Lines

Have someone check your pressures & temperatures in your refrigeration system. Also check the compressor amps with an analog meter to see if the amps fluctuating. There might be something wrong with the compressor.

The air conditioner makes a loud sound when the ac trys to kick in. When i put it under fan it works fine and makes no noise.

Sounds like your compressor is seized/stuck and the unit needs a new compressor. If this is the case it should make a loud buzzing noise for a while and then click when it stops trying.

A.C . makes a buzzing noise...

If you can make repairs yourself a motor is only about $40 and a capacitor about $10. Either could be the problem. If you have to pay someone to do it buy a new one.

I makes a very loud noise

Had same problem with Ge AC. Unplug take out of window and remove all cover screws. Pull up on cover and pull cover off ac, Remove front cover as well there are a couple screws in the front. When looking at front of ac, hit the Styrofoam housing towards your left (towards control panel). Spin fan blade to make sure that it is clear. Plug in to double check. I put a couple quarters between the styrofoam and the metal housing, so it would not slide back. Also tape the styrofoam between the seams this helps with better cooling. Use some good tape nothing cheap. I used black duck tape. It took about 20 mins. The hardest part is re installing the AC.
