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. If 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. The front grill of a window air conditioner needs to be removed on a regular basis to clean the filter. These 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.Whereas putting in a central air conditioning system typically requires a professional crew, installing a window air conditioner is a cinch. efficiency of an ac unitEven a self-described hopeless amateur ought to have little trouble here. central air conditioner parts storeIn fact, you’re likely to become somewhat of an expert on the process, being that most homeowners choose to remove window air conditioners at the end of the summer and reinstall the units the following year. average cost of an air conditioner unit

Bear in mind, however, that not all window designs are meant to accommodate such a large, unwieldy box. The following instructions apply only if you wish to install a window air conditioner in a sash or double-hung window. - Window air conditioner - Insulating foam strips Window air conditioners are sold in a variety of sizes, and each model has a different cooling capacity, rated in BTUs. Many online calculators exist to help you identify the number of BTUs needed to efficiently cool a room of a given size. BTUs aren’t your only concern, however. You also need to be certain that the unit physically fits in your window. Before you shop, measure the width of the window opening and don’t purchase any air conditioner whose housing wouldn’t leave about two inches of wiggle room on either side. Once you’ve purchased and unpacked an appropriately sized air conditioner, you’re ready to install it—but first, grab a friend. Two pairs of hands are best for all but the very smallest air conditioners.

Before you move on, attach any provided rails, flanges, or accordion-style panels (or wings) according to the manufacturer’s instructions, using the provided screws. Now your first step is an easy one: Open the window! Open it wide enough to accommodate the height of the air conditioner. Next, pick up the unit and rest it on the bottom of the window frame. Have your helper hold the unit in place while you see to the remaining tasks. Most window air conditioners are designed with two flanges—one that runs along the top of the unit, another along the bottom. These flanges facilitate the installation process and improve the air conditioner’s stability. After positioning the bottom flange so that it abuts the windowsill, proceed to lower the window sash (which you had raised in Step 2) until its bottom rail meets the top flange on the unit. The air conditioner should now be held in place by the top sash, but have your helper keep hold of it lightly until you’ve completed the next step.

Your air conditioner probably came with one or two small angle brackets that must be used to secure the two sashes together, preventing them from slipping apart or from being accidentally opened, either of which occurrences could cause the air conditioner to fall out of the window. Place the angle bracket against the top sash where it meets the top of the bottom sash. Mark where the screws should go, drill pilot holes, and tighten the screws using a screwdriver. Extend the accordion-style panels (which you attached in Step 2) and secure them to the window using the manufacturer-provided screws. At this point, make sure that all screws that came with the unit have been secured according to the instructions. The last step is to seal the opening between the upper sash and the lower sash, which has been raised to accommodate the unit. Your air conditioner should have come with a foam insulating strip. Cut it to length, then fit it snugly into the gap between the lower sash and the glass panes of the top sash.
