It’s hard to enjoy your summertime with a noisy air conditioner. The sound can be driving, grating and clicky or just plain loud for some people who live in apartments where they are one of the few sounds that penetrate from outside their homes into interior spaces.
If you hear any of the following noises coming from your air conditioning system, this could be an indication that it’s time for repairs or replacement. To help diagnose what’s wrong with their unit and how best to fix them, here are some common air conditioner noise causes that should never go unnoticed by homeowners!
Humming Noises
Two reasons can cause the humming noise on your air conditioner. Humming noise can often be heard when there is a loose part or an issue with refrigerant. It may also create the vibration that produces these humming sounds, causing electrical interference and what you hear!
One more serious cause of the humming sound might be that a defective contactor relay switch may damage your air conditioning unit. This component is designed to start the outdoor condenser when it receives the signal from the thermostat.
Still, if you have issues with electricity in your system, then this will cause severe damage and expensive repairs for central refrigeration units. In this case, you need to contact a technician right away.
Banging Noise
The banging noise your air conditioner is making could be an indication that something’s wrong with the compressor. This part of AC systems distributes refrigerant throughout to remove excess heat from homes, so it can become loose over time. Sometimes, the parts of your air conditioning system will become detached while you’re using it.
This means that they are hitting against something inside and making a noise like someone beating on metal with a hammer or clanking together pieces of equipment because there isn’t anything else around for them to resonate off to!
If this is constantly happening, we recommend getting in touch as soon as possible with an air conditioner technician who can come out and fix things up before any more damage gets done to your air conditioning units.
Buzzing Noise
With so many possible causes for an air conditioner’s buzzing noise, it’s best to leave this matter in the hands of professionals.
The most common ones include loose parts or debris inside your air conditioner unit; faulty fans blades on their own, which can be caused by dirt getting lodged between them as well.
On a more serious issue, buzzing noise may be an indication that there’s something wrong with the copper lines which connect to it. The most severe issue can cause the buzzing sound and result in refrigerant leaks, so don’t ignore any noise and hire a technician immediately.
Screeching Noise
The most common issue of an air conditioner making a screeching or squealing noise is the malfunctioning fan motor in your outdoor condenser unit. Centralized cooling systems feature fans that are designed to remove heat from refrigerant; if yours sounds like it’s causing you some trouble, there could be something wrong with these motors!
The fan motor is one of the most important parts of your house because it helps keep you cool by distributing air throughout each room. If this machine starts making an unusual noise or screeching, there may be something wrong with its blades, so make sure to contact an air conditioner expert immediately.
Rattling Noise
If you’re hearing a rattling noise coming from your air conditioner, it could be because there are some loose sticks or dirt in the outdoor ac unit. You can take care of this by taking off pieces and cleaning out any leaves that might have gotten stuck during the winter months!
However, it can also mean a serious problem; the damaged electrical contractor may cause the rattle of your air conditioner. If you notice a malfunctioning worker, this should not go ignored as the consequences can lead to significant issues.
Clicking Noise
Although clicking noise is normal when you first turn on an air conditioner, continuous clicking sounds from your air conditioner may indicate a malfunctioning thermostat. It’s not easy to remove and install new ones, so call someone who can help you with the process!
Bubbling Noise
If you hear a bubbling noise coming from your air conditioning system, it could be because of excess moisture in the drainage line. This type of problem can happen due to blockages or cracks that form when too much pressure builds up behind them and then releases suddenly – which causes these openings! You might want to take care of this by cleaning out any clogs.
Hissing Noise
If you hear a hissing noise coming from your air conditioning system, this could indicate a moderate to severe duct leak in the house. The sound may also result when one or more components fail, such as expansion valves and air filters, which should lead professional helpers for inspection before anything else happens!

Common Noisy Air Conditioner Fixes You Can Do
Check for Fan Blades Placements
Rotate the air conditioner’s fan blades to be correctly positioned. If you find any of them angled awkwardly or not in line with each other, don’t try to fix it yourself! Instead, call for professional help as soon as possible because this will lead to more serious problems.

The first thing you should do when your air conditioner starts making noise is to look at all the screws and bolts on its exterior. Maybe something is blocking one or two, preventing them from turning properly.
