Your air conditioner is a central component of your Summer; in Windsor/Essex, the midday heat can be overwhelming, and it only makes sense that you’ll rely on your air conditioner to get you through the day. Air conditioner maintenance is an important part of homeownership, as you need to take steps to prevent your HVAC unit from malfunctioning or underperforming. Occasionally, you may experience troubles with your air conditioner, such as the unit making unusual or loud noises.  Should problems arise, here are a few explanations as to why your air conditioner is making loud or strange noises:


Excess Debris:


Due to your air conditioner being uncovered and exposed in your backyard, there is a pretty good chance that there is a foreign object inside the unit that is creating a rattling noise. It is incredibly possible that leaves, sticks, stones, and other types of outside debris have fallen into your air conditioner and should be removed by an HVAC specialist as soon as possible.


Untightened Screws & Bolts:


The screws & bolts that help keep your unit intact need to be retightened occasionally, to ensure they are not losing their grip. If any screws or bolts are not adequately tightened on your unit, you will undoubtedly hear a rattling sound, which is likely the side panels moving while the unit is operating. If you can locate the source of the rattle, you can attempt to refasten the bolt or screw yourself, or you can call an HVAC specialist for further assistance.


Loud Compressor:


Over time, your air conditioner’s compressor may begin to make a loud noise. This noise could be indicative that your compressor is starting to wear out but does not implicitly mean that it is close to breaking. Therefore, you can leave your compressor in your air conditioner, if you’re okay with the noise it is making. If the sound perturbs you it is making, reach out to your local HVAC company for further diagnosis to ensure that is only is your compressor.




Another reason that air conditioning maintenance is imperative is that eventually, the lubrication that is applied to moving parts runs out. Even a filthy fan blade could create a scraping noise as it rubs against the unit casing. The noise that you hear from your air conditioner unit while the fan blades are dirty could be a squeaking or grinding sound.




If you are hearing a hissing noise coming from your air conditioner, it is essential that you contact your local HVAC specialists immediately. The hissing sound could be caused by leaking refrigerant, which could be dangerous to your family as well as the unit itself.


Preventative maintenance is the best kind of maintenance. It ensures that you are taking the necessary steps to preserve the condition of your air conditioner. Although you can attempt to repair these issues by yourself, it is recommended that you enlist the help of your local HVAC company, so that your unit receives the care it requires.
