3 Types of Loud AC Noises and How To Fix Them
Sometimes your AC will not shut down immediately when facing an issue; it will give you signs. One sign indicating a problem will be loud noises when you start your AC.
If you are worried about these loud noises and want to solve the basic issues yourself instead of calling a professional, we will be helping you out with this.
Let’s discuss “three common AC noises when starting it”. You will not only find out the reason behind the Noise but also be able to fix it on your own.
1. Banging Noise
A loud banging sound from the AC can indicate two main problems:
- Something is Stuck – A loud banging or hammering sound from your AC can represent if something is stuck in it. It can be any junk or other scrapes. This junk can block the air passage of your AC and thus make a sound every time you turn it on. Remove the junk and clean your AC to see the desired results.
- A Loose Fan – If you fail to find the junk in your AC, the banging sound might represent a loose fan. Use a screwdriver to tighten up the flaps of the fan to see the sound disappear.
2. Screeching Noise
A screeching noise can sound like a metal being rubbed against a metal. If you detect a screeching noise in your AC, it can represent an issue with the fan’s motor.
Typically, when the bearings of the AC fan motor wear out, they produce a screeching noise as soon as you turn on the AC.
Since the damage is irreversible, replacing the fan motor is the only solution to avoid Noise.
3. Clicking Noise
If you hear a clicking noise from your AC on turning it on, it represents an issue with the wiring of the AC. Especially if you turn the AC, it makes a clicking noise but doesn’t start working.
The electrical issues can involve a faulty thermostat, a poorly working compressor, or a fused capacitor. Instead of resolving the issue on your own, it is advised to report the problem to a specialist for a proper checkup of the unit.
How To Stop AC From Making Loud Noises
To stop loud noises from your AC, you can take the following actions into account. Your air conditioner will thank you for these favors by behaving in a sensible polite way.
Tighten Up the Loose Screws
The screws inside the air conditioner might loosen over time and produce weird noises. Moreover, they can also make a risk of breaking the machine parts free, leading to more problems in the future.

Clean Up the Coil Fins
As dust accumulates over the coil fins, it can deteriorate the performance of your AC over time. Use a brush extension with your vacuum to collect the dust settling over the coil fins.
Straighten Up the Bent Blades
Since the fan blades help remove the hot air inside the room to be evacuated outside, they can get bents and curls over time due to several factors.
Use a fin comb to straighten up the bent blades carefully. Make sure they are also tightened and not just hanging over the fan.
Clean Up the Junk Inside
Open the AC at least once every six months for its thorough cleaning. Sometimes, debris and junky items might get stuck inside, deteriorating the AC’s efficiency and producing loud noises.
Regular cleaning can help maintain the health of your AC at its best.
Lubricate the Motor
