If it is indeed a true vibration, it could be a number of things. I have seen bad bearings do this off and on as the cooler runs. Could be something going wrong with the blower motor. There are several things that need to be checked to properly evaluate the problem you are describing.

I have a MasterCool evaporative cooler on the roof of my house. Its making a loud squeaky sound when I turn it on. Maybe something is rusted because my cover blew off during a storm and I didn't...


If you were to stand at the condenser for let's say 30 minutes, would the sound be constant throughout or would it go away and come back and few times. If it goes away and come back, it may be caused by your compressor. If it's constant, it may be the condenser fan. Now, if you're convinced that both are fine, then the squealing is probably caused by vibrations from the chassis. The fact the you have a makeshift cover may give you hints as to where the sound is coming from.

Air conditioner isn't blowing cold! Fan works okay but air isn't cool. Can hear hissing sound that sounds like normal compressor function. Do I need a coolant recharge?


You will need the condenser coils repaired before you can charge it. These come from the factory sealed and they should not ever need a charge unless you have a leak. The hissing sound is more likely air in the system being pumped by the comressor and it is coming out a hole in the coils.

When the wind blows my motor stalls and blows the breaker. Please reply slowly as my english in not so good.


The horse power of the motor is either to small or you can also adjust the motor pulley, loosen the allen set screw on the motor pulley, turn it in one or two full turns. The readjust the belt, there will be less airflow, but the amprege draw on the motor will be reduced.
Have a great day.
Sincerely,

Works fine but started making a blowing sound kind of like a rush of air


Maybe the unit has switched to a higher speed, does it have a thermostat that changes speeds automatically?
Make sure the pads are not plugged up. Make sure you do not have a damper somewhere that has partially closed.

Make sure you have enough exhaust openings in the house. Turn on the unit with an outside door open and see if the result is the same. To me it sounds as if you have too much back pressure and not enough ventilation.

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.
