Common Strange Noises Your Air Conditioner Can Make: Know What They Mean
Understanding the type of sound originating from your air conditioner and recognising its source are two vital tasks for timely repairs. Thus, you can detect whether your noisy air conditioner requires some DIY or expert intervention.
Let’s unfold the mystery of air conditioner noise types and why they happen in the first place.
Humming
Is your AC making humming noises lately? According to AC Repair in Dubai experts, a damaged contactor relay switch might induce a humming sound. The contactor relay switch is designed to initiate the outdoor condenser unit after receiving a signal from the thermostat.
Unlucky for you, there’s no DIY solution for an aircon unit that makes a constant humming noise. Get your AC unit checked by a certified technician immediately. Otherwise, you might have to face expensive and irreversible repairs.
Hissing
Is it a central air conditioning unit that has been making a hissing sound? If yes, look out for air duct leaks. Also, an incompatible air filter or malfunctioning expansion valve might be the culprit for hissing noises.
For a compact or slit air conditioner, the hissing noise can stem from the refrigerant leakage. Neglecting such noises can have a toll on the compressor. Moreover, consider repairing air conditioners whenever you notice such noises.
On a related note, the technician will recharge your aircon unit with the compatible refrigerant to the safe limit.
Banging or Clanking
In case your noisy air conditioner sounds like banging or clanking, chances are that its parts are loose or broken. For instance, it could be anyone from the following components:
- Loose fan blade
- Bent motor mount
- Compressor
However, debris inside the noisy AC unit can be the source as well. As a quick fix, you can shut down the unit and inspect it for further damage that is visible. If you can’t spot a problem, it’s better to contact an AC Repair Dubai technician.
Screeching
Nothing can be more annoying than a continuous screeching noise from your functioning air conditioner. As per experts, an AC unit typically makes a screeching sound because of the defective fan motor in the condenser unit.
Additionally, a broken motor inside the compressor unit can generate a screeching or squealing sound. If you are handy with tools and minor AC repairs then you can check the fan and motor. Look out for worn-out bearings or a slipping belt.
In addition, you can lubricate moving parts if needed. Otherwise, call an expert if you are not sure how to proceed.
Buzzing
Don’t you dare to ignore a buzzing noise from your noisy AC unit. Typically, buzzing noises indicate unbalanced or loose fan blades in the outdoor condenser unit. Besides this, buzzing noises can signal issues with the components below:
- Outdoor fan motor
- Condenser coils
- Loose electrical parts
- Capacitors
Additionally, you can check the copper lines for obstructions before repairing air conditioners. If you don’t find anything suspicious, consider calling AC Repair Dubai pros and make your haven a safe space again.
Clicking
Many air conditioners start with a clicking sound but you should be alert if the sound persists throughout the cycle or until you turn the unit off. According to aircon technicians, a malfunctioning thermostat can generate clicking sounds.
To be honest, removing the outdated thermostat and installing a new one on your own can be challenging. Hence, consider professional intervention to deal with clicking noises.
Bubbling
According to reliable sources, your air conditioner may be exhibiting a bubbling noise because of excessive moisture. Probably, a crack, blockage, or hole in the drainage pipe of your noisy air conditioner is the reason.
So, inspect the drainage line if you are comfortable with disassembling the unit and repairing air conditioners. Or else, contacting a skilled air conditioner fixer along with the best tools will be sufficient.
Rattling
Generally, rattling noises from an air conditioning unit indicate debris or loose parts. For instance, examine the outdoor unit and see if anything bothers it. However, you might have to disassemble the condenser unit to bring out the debris and inspect the internals.
On the other hand, the rattling sound can stem from a damaged electrical contractor too. If you don’t take steps immediately, the issue can spread to the compressor. Hence, get in touch with a trusted AC repair technician and experience the difference.
Why a Noisy Air Conditioner Matters
Ignoring strange noises can contribute to bigger problems. Indeed, unusual sounds may signal that your air conditioner is working harder than it should. As a consequence, repairing air conditioners and facing sarong electricity bills become unavoidable.
Save your air conditioner in the schvitzing summer of Dubai from potential trouble with regular preventive maintenance.
Maintenance Tips to Reduce Noise
Want to maintain an efficient air conditioning system? Nothing works better than caring for your noisy AC unit. Whether your AC making humming noises or it keeps clanking, try the following steps to avoid such strange sounds after fixes. Also, you can extend your AC’s longevity with grace with a maintenance routine.
Filter Changes
Dirty filters prevent airflow and cause the aircon unit to work harder. Also, this can lead to enhanced noise and wear. So, change your filters every 1 to 3 months to keep up with the desired efficiency.
Outdoor Unit Cleaning
Outside, the condenser unit has to struggle with debris. As a result, you experience a noisy air conditioner. However, cleaning the outdoor condenser unit can keep obstructions away and your unit functional.
Duct Insulation
Are you sure that your ductworks are properly insulated? Or else, your ductwork can make excessive noise that might appear to be alarming. So, pay attention to insulating ducts and reduce sound transmission throughout your home.
Professional Maintenance
Additionally, an annual check by a professional AC Repair Dubai company can catch issues before they give you a headache. So, opt for regular maintenance to keep your system running efficiently and quietly.
