What You Should Know About Aircon Filters and Why They Matter

Learn why clean aircon filters matter and how regular aircon servicing Singapore can improve cooling performance, airflow, and system efficiency with AirconFairPrice.Sg.

What You Should Know About Aircon Filters and Why They Matter

A properly functioning air conditioner is one that most Singaporean homes will depend on, and it should not make any sound beyond a slight hum. Whereas the sound of the compressor or fan as they run is quite normal, abnormal vibration definitely is not. Therefore, when there's an unusual rattling, vibrating or shaking from your aircon, these signals that there's a possible malfunction. Not giving these warning signs due attention can make things get out of hand which will cost you more money for repairs, the comfort level will drop because aircon is unable to cool properly, and in the worst case scenario, the whole system might shut down.

Knowing the reasons behind your AC being so vibration-prone will enable you to spot the issue before it escalates further and causes big damage. The system could be either brand new, or has been used for several years but the basic first step is always to find out the actual source.

AirconFairPrice.Sg experienced technicians offer a whole range of services like professional aircon servicing Singapore to keep your aircond running in top condition, from repairs and maintenance to installation of aircon units for both residents and commercial areas.

The reason behind persistent vibrating aircon should never be one of the things we ignore

Bathroom and other household appliances naturally vibrate as they age. Although movement is expected to an extent, the shaking of the aircon is generally a sign of the mechanical or installation issue. By overlooking the vibrations you risk:

  • Pieces internal being unconnected

  • Accelerated aging of various parts

  • Higher consumption of electricity

  • Drop in effectiveness of the aircond system

  • Leakage of water

  • Damage to the compressor

  • Heavy repairs at short notice

Periodic checking and servicing of your AC can help find these kinds of problems early before the problem actually causes a breakdown of the entire system.

1. Loosening of installation fasteners or brackets

Loose fastening of the hardware of the air conditioner is by far one of the leading reasons for vibrations.

The indoor evaporator unit is fast and securely fixed to the wall bracket, on the other hand, the outdoor heat exchanger can be put on either metal bracket or a solid base of concrete. After a couple of years of using aircon units constantly, screws or bolts will become loose, and brackets will get loose, which is natural but also the first sign of possible issues.

The symptoms that you might get due to that would be:

  • Some kind of rattling

  • Visible shaking

  • Unit moving when it starts

  • Sound of metal vibration

Cutting down hardware loosening either through tightening or replacing worn-out hardware is a quick, effective solution.

2. A dirty blower fan

A dirty surface inside the blower fan will lead to the fan being out of balance, because of the weight of the dirt being heavier on one side of the fan.

Blower running at a faster rate can move a large amount of dust from your home. The dirt that clings to the blades of a blower wheel changes the center of mass of the wheel and therefore a vibration ensues.

You will mostly see symptoms like:

  • Air from the vents is weak

  • A lot of noise

  • Physical tremors inside the unit

  • Particularly after some period of time dust may be released from the vents

Regular aircon servicing Singapore is carried out in full professionalism, cleaning the aircon blower wheels, filters, coils, and also the drainage system to bring fresh and clean air from within.

3. Fan blade that is not in a balanced state

Thousands of times a few hours a day outdoor condenser fans make one turn.

The turning of the fan becomes very difficult to balance if one blade gets bent or broken, which causes an over vibration.

Majorly, this will be caused by:

  • Falling debris

  • Accidental impact

  • Rust

  • The result of continuous use after wear and tear

If you keep ignoring, it may eventually lead to wearing out of the motor's bearings.

4. Motor bearings are already worn

Floppy bearings present in fan motors enable the fan to move easily by providing support and reducing the friction.

Over time, if you don't take care properly that these parts don't wear out, you'll get the following symptoms:

  • The sound is quite like that produced by grinding

  • A very harsh squeal at a high pitch

  • Very strong vibration

  • Less efficient system

The motor itself will be replaced as a last resort only in case the bearing isn't separable from the motor.

5. Issues with the compressor refrigerant

Compressors can be seen as the soul of every aircon. These compressors are the most essential parts of aircons that Singapore property owners rely and trust.

Vibrations from compressor damages can be very intense. These can cause serious vibrations across your entire cooling system.

The reasons or factors may include:

  • Mechanical parts worn out

  • Mounts of a compressor loose

  • Refrigerant issues

  • Potential problems with the electrical aspect

Getting a timely aircon repair in Singapore can stop the failure of your compressor completely.

6. Inferior Aircon Installations

Bad installations may be one of the leading causes of vibration.

A well-functioning brand new air condition unit may still have a high likelihood of vibrating if its installation was poor.

Here are installation errors that can lead to unwanted vibration:

  • Unbalanced mounting points on the wall

  • Weak base or platform

  • Support for pipes not given

  • Condenser position incorrect or off-center

  • Not properly levelled

With a properly installed aircon, Singapore professionals can make sure that all the elements of your cooling system are fixed correctly and properly adjusted so that it will run smoothly and be quiet.

7. Unfixed Internal Mechanical Parts

AC units are packed with numerous internal moving parts.

The fastening screws of following parts may get loose gradually, due to frequent usage of your AC over many years:

  • Fan motor components

  • Electrical control panels

  • Safety covers for coils

  • Drain tray supports

The loosening up of the fastening screws can lead to the vibration issue as the part is left freely moving about.

The early identification of such issues before they become a big vibration problem will significantly ease their resolution by routine checks and examinations.

8. Filters are Full of Dirt

The only thing which the blocked air filters cause to the aircon directly is the limitation in the airflow, not any noise.

The extra pressure on the blower motor can result in the motor's vibration or movement being passed through the unit in larger portions than normal.

Clogged filters may also lead to:

  • Coils freezing

  • Lesser quantity of air

  • Consuming higher amounts of power

  • Poor cooling performance

Cleaning and replacing of the filters regularly is one of the easiest ways to do maintenance and prevent problems, thus saving yourself from the hassle later on.

9. Isolation Pads of Rubber Damaged

Situated on rubber bases is an outdoor condenser unit which is very essential because it minimizes the level of vibration.

These pads may get affected as time goes on to such an extent that:

  • Cutting of the pads will be noticed

  • The pads become flat/uneven

  • The pads are so rigid that you need to use a tool to compress them

  • Wearing out

Your house, especially walls, floors, and metal brackets, would absorb the vibration when you have no rubber pad underneath to serve as a buffer. Thus, your room may start to shake.

The most affordable of the parts that should be replaced is the rubber pads on a regular basis as this would stop your aircon from shaking so much after a while.

10. An Aged Aircon System

Everyone and everything, including mechanical equipment such a refrigeration unit, come with an inevitable end or time limit when their functioning is at its maximum potential.

You can expect that the old air-conditioned system is going to have some problems like:

  • Motors get worn

  • Out of balance fans

  • A lot of unfastening

  • Compressed device becomes tired

If your HVAC system needs repairs on a regular basis (like once in every couple of months), then the aircon replacement in Singapore option might save you a lot of money in comparison to other alternatives.

Thanks to the development in technology and energy-saving features, today's cooling solutions have much noise control with the added benefits of being environment-friendly.

Maintenance that Curb Vibrations

Vibration problems tend to be very slowly developing issues that could result in very serious ones if unnoticed over the years or even years.

A maintenance plan that is carried out beforehand to identify such vibration-related issues before they escalate is an important factor in that:

  • Fastening of any hardware components that are loose

  • Removing dust or dirt that has built up in the rotating blades

  • Washing evaporator coil fins

  • Removing dirt or soot from condenser coils

  • Inspecting motors for problems

  • Ensuring refrigerant pressure is at the right level

  • Examining the integrity and tightness of electrical connections

  • Carrying out performance tests to confirm cooling effectiveness

Regular air conditioning technician visits in different areas around Singapore can greatly minimize the time you spend on troubleshooting while also guaranteeing that there will be no loss of the efficiency or working capacity of your AC unit.

Signs that it is Time to Get Help from a Repairman

Here are the signs that you may consider that there is an aircon breakdown in your unit and you need to get it fixed as soon as possible by an expert repair service:

  • Very noisy rattle

  • Persistent movement

  • The wall or other surface where the unit is attached vibrates

  • Not enough cooling

  • Water dripping

  • Smells

  • Switching off the entire circuit

  • The machine has become way more noisy

In most situations, these are warnings that there is a problem with the appliance which would require proper diagnostics.

Besides, you could even end up doing more damage by your own hands if you carry out maintenance involving parts with electricity and cooling agents. Therefore, you should be careful in these areas.
