A window air conditioner is a great way of keeping a room cool in the absence of central air conditioning. These window ACs come as a comprehensive unit that can be mounted on a window or even a specially designed aperture in a room. You do not need to install additional piping or separate condenser units. Installing them is also far simpler than designing and installing central air conditioner units. However, the biggest problem with window air conditioners is that they can sometimes be noisy. Here are some steps that you can follow to troubleshoot a window air conditioner that is excessively noisy or loud. If your window air conditioner has been operating at a steady noise level but suddenly starts making a loud noise, it’s possible a foreign object has fallen into it. This is quite common in these types of air conditioners because the outer part of the unit hangs outside your window, making it easy for small animals or flying debris to enter your air conditioner. If your room is on the ground floor, it’s possible that a ground dwelling animal like a rat or lizard may have made your window unit its new home.

Switch off your air conditioner immediately, unplug it, and open the front grill. Using a flashlight, peek inside the unit. Remove the foreign obstruction, fasten the front grill back in place, and start the air conditioner once more. In certain cases, the presence of an intruding object does damage that causes problems even after it’s been removed. The fan blades inside your window air conditioner, for example, can become bent if they strike an object that falls inside the unit. Check to see if the blades are straight. If not, straighten them until they are properly aligned. This can be done by hand or by using a strong pair of pliers if necessary. If you are not able to figure out whether the blades are bent or not, consider seeking professional assistance. Window air conditioner units are heavy, have lots of moving parts, and are precariously mounted in window frames. As a result, these units are prone to a lot of vibration if they have not been mounted correctly.

Touch the sides of the window frame on which the air conditioner is mounted. places that buy used ac unitsIf they are vibrating excessively, you should call the people who installed the air conditioner and ask them to fix it so that the vibration is minimized.ac unit too small for house The front grill of a window air conditioner needs to be removed on a regular basis to clean the filter. non window ac unitsThese grills are usually held in place by a simple locking mechanism. While a dirty filter is certainly problematic for the unit’s function, it won’t cause excessive noise. However, if the grill is not put back properly following a cleaning or the locking mechanism is defective or damaged, it can vibrate around and cause a lot of noise.

Remove the grill and set it back on properly to eliminate this noise. If the locking mechanism has been damaged, you may have to replace it. If the fan motor is not properly lubricated, it can result in a loud persistent noise. If this is the case, switch off the air conditioner to avoid damaging the motor. In the middle of heat wave, this cause is the worst one to discover at the root of your noise problem. Since most fan motors are sealed, you may have to call for professional assistance to lubricate the fan motor.Written Written Ah yes, this is a very annoying problem that I myself have had trouble with. I would recommend you stop running and unplug the unit until you fix this problem. Usually your ac unit is making this noise due to water build up, but there could be other problems with the unit as well. The compressor or condenser inside the ac unit could be on the fritz, there could be two wires touching making a malfunction, there could even be something inside your unit that is obstructing the fan.

Whatever the case may be, I would get in contact with an AC repair professional. He/she may be able to give you the exact answer you need, and this also will prevent you from any unnecessary harm. If you find out the problem is easily fixable only then would I recommend you save some time and money and do the repair yourself. I had to replace a fan blade on my unit, and I went to Air Conditioning Parts for an original manufactured replacement. Good luck and hopefully I have helped you out today!Written Written I agree, you must stop using the unit and keep it unplugged till a time when a HVAC professional has checked it out and given it a bill of clean health. Otherwise, your AC may be leading to heating up or too many fluctuations which may cause either a short circuit or the fuse to blow up. This could even lead to an electrical fire.Quite simply, your AC requires to be serviced which means that the filter needs to be cleaned and the AC needs to be checked inside out. In high moisture areas, particularly after a rainstorm like the one you’re talking about that happened, what happens is that there is water or moisture build up inside the unit which is causing this cracking and popping.

In extreme cases, this could be a malfunction due to some form of fault in the wiring. So, whichever way it may be, you need to get in touch with an HVAC Contractors, preferably through Bakers Brothers plumbing.Loud air conditioner, please hope me!
