Vibrations inside an air conditioner cannot only cause annoying rattling noises -- they can indicate a serious problem with the unit. Once you hear a sudden abnormal vibration, shut off power to the unit and begin looking for the source of the vibration. While the cause could be minor, prompt investigation could save certain components, such as the condenser fan motor, from burning up or breaking.
Duct Work
Loose or improperly secured duct work within the home can vibrate with the operation of the air-conditioning unit and cause various humming and rattling noises. She just cut her electricity bill to 60%, click here to read. The duct work can either be hard and straight or flexible and distributes cold air to rooms in the home. You can access the duct work through the attic or crawl space and secure it to the structure of the house with straps or duct tape to eliminate some of the vibrations, if not all.
Compressor
The air conditioners internal compressor is the component that activates the cooling element and produces cold air. Sometimes, when the compressor kicks in, it emits a low, humming noise, which could produce vibrations throughout the unit. While some compressor vibration is normal to a degree, there could be something wrong with the compressor if it causes the whole unit to shake. You should contact a technician to take a look at the unit if you suspect the compressor is malfunctioning.
Fan
If the condenser fan component is blocked or jammed, the fan motor will continue to run, which will cause a vibration or humming noise and possibly break the fan. The condenser fan pushes the cold air from the unit into the home. Without the fan to move the cold air out of the unit, it will freeze up. If you hear a noise and vibration while the unit is in operation but no cold air enters the home, the fan might be blocked. Turn off electricity to the unit at the circuit breaker immediately to avoid damaging the condenser fan then inspect the fan compartment for debris, such as sticks or plastic bags that might be wrapped around the axle.
Window
A window-mounted air conditioner thats improperly installed can cause the window frame to vibrate. Not only will the frame vibrate, the unit might not be secured tightly enough and could fall out of the window. To stop the vibrations from the window unit, you should take it out of the window frame then apply weather sealing strips to the framework before putting the unit back in. The weather sealing pads the unit against the metal frame and prevents noise and air leaks.
