A noisy air conditioner can be frustrating to deal with, and it can also be a sign of a serious problem. If your aircon has been making loud noises, you’ll want to get to the bottom of the problem as quickly as possible. These tips will help you to quiet your unit down.
Dealing With A Noisy Fan
If your air conditioner is making loud rattling noises, there’s a good chance that your fan is the culprit. It’s important to make sure that your fan is cleaned and well-maintained. If the area around the fan is dirty, is won’t be able to function properly. This could lead to buzzing or humming noises, and it could also have an impact on the performance of your unit.
Before you can deal with these issues, you’ll have to locate your fan. You should be able to find it quickly once you open up your aircon’s cabinet. Once the fan is visible, you should clear away any dust or debris that you see around the fan’s blades.
If there’s no visible debris, you shouldn’t assume that the fan isn’t the source of the problem. It’s also possible that the fan blade is loose. Thankfully, this is an easy fix. All you’ll need to do is tighten the blade with a screwdriver.
You should also examine the blades of the fan to see if any of them are damaged or bent. If there are bent blades, the fan doesn’t necessarily need to be replaced. Instead, you can gently straighten these blades by hand.
Issues With Loose Screws
Rattling noises can also be a sign of a loose screw. This is a common problem. Air conditioners vibration when they are running, and these vibrations can cause screws to loosen. If your unit has gradually been getting noisier, you’ll want to grab a screwdriver and get to work.
When you’re looking for loose screws, one of the first places you’ll want to check are the screws in the panels of your unit. These are the screws that are most likely to come loose. Turn off your unit, tighten the screws, and then turn the unit on again to see if the problem is resolved.
Friction From Moving Parts
There are many of small moving parts inside your air conditioner. If these parts aren’t properly lubricated, they can produce friction. Not only can this make a lot of noise, but it can cause parts to be damaged, which can eventually lead to costly repairs.
This is another problem that has a fairly simple solution. If these parts are periodically lubricated, there will be less of an issue with friction. This will put a stop to the noise, and it will protect the parts as well.
With that said, you’ll want to be careful when choosing the best type of lubricant to use with your unit. Usually, SAE 10 oil is recommended. You may want to consult your unit’s manual to see if there’s a particular type of lubricant that it recommends.
Clogged Coil Fins
Your coil fins can become clogged by dirt, dust, or other types of debris. This can cause an air conditioner to be very noisy, and it can also have a major impact on efficiency. If this is the case, you should actually be able to take care of the clog on your own.
A vacuum cleaner with a brush attachment can be used to clear away debris. It’s also a good idea to take a closer look at the coil fins. If you notice that any of them are bent, you’ll want to straighten them out. Taking this step should be able to solve problems like a humming sound coming from your air conditioner.
Dealing With Loose Parts
Your aircon’s fan and screws aren’t the only part that can become loose with time. Many of the parts that keep your unit running could become loose or out of balance. If this happens, you’re likely to hear a clanking sound.
Once a part is loose enough, it’s likely to stop working entirely, which means you’ll have to repair or replace that part. You can check for loose parts by opening up your unit. In some cases, you’ll simply be able to secure a part by tightening a screw, but in other cases, you may need the help of a professional.
Watching Out For Debris
It’s possible for debris to get inside your air conditioner. This is especially likely to happen with an outdoor unit. Once inside, this can cause a host of problems, and it can also lead to a lot of noise.
You can keep debris from becoming a problem for you providing that you regularly clean the area around your outdoor unit. It’s good to dust and clean around your indoor unit as well, especially if it’s in a part of your home you normally don’t visit, such as the loft.
As mentioned above, you can get rid of dirt and dust with a vacuum cleaner attachment. Make sure your unit is off when cleaning it this way. You can also open up your condenser unit and remove any pebbles or leaves that you see.
What To Do When You Can’t Solve The Problem
While many of these issues have easy solutions, you won’t always be able to take care of this problem on your own. Sometimes, a noisy air conditioner is a sign that the unit is due for replacement. In other cases, it may be necessary to replace certain parts.
If you’ve tried the suggestions above, and you haven’t been able to take care of the noise, the best thing you can do is call for professional help. Professionals will be able to examine your unit, diagnose the problem, and provide the needed aircon repairs.
A noisy air conditioner can be a problem, but luckily, it’s an issue that’s very solvable. If your aircon has been making noise, take a look at these suggestions and see if you can get to the bottom of the problem. It is also one of the common problems even after you have done your aircon servicing. Addressing these problems quickly can protect your unit and keep your home cool.
