Facts And Functions Of Your Aircon Unit Condenser

What is an aircon condenser?

A condenser or aircon condenser is the outdoor portion of an aircon unit or heat pump that either releases or collects heat. The purpose of the condenser is to receive the high-pressure gas from the compressor and convert this gas to a liquid. It does it by heat transfer or the principle that heat will always move from a warmer to a cooler substance.

Why is an aircon condenser important?

An aircon condenser unit helps you to manage the humidity and temperature in your home. It enables you to keep things cool especially on hot summer days in Singapore. Among all aircon unit services, homeowners most often need maintenance and repair of an aircon condenser unit to keep their homes cool.

An aircon condenser unit essentially dissipates the heat carried to the outdoor unit. This allows the cooling process to continue. The condenser is one of three primary elements in your aircon unit. The other two, the evaporator and compressor, are also important.

How long does an aircon condenser last?

An aircon condenser unit that’s installed by experienced professionals and receives regular maintenance checkups should last as long as the aircon unit itself. Depending on the model, this can be anywhere between 10 to 20 years.

That being said, accidents, irregular maintenance, and normal wear and tear can still cause one or more components inside your aircon condenser to fail or become less efficient over time. Some malfunctions can be easily repaired, while others require complete replacements.

What will happen if something goes wrong with your aircon condenser?

A faulty aircon condenser can cause a number of problems. Such as:

1) Your aircon unit may not be able to produce as much cool air as it used to.

2) Continuous usage of your aircon unit with a failing condenser may result in higher energy bills for you despite less efficiency and comfort.

3) It may also be a sign of a compressor issue or a refrigerant leak.

4) There are weird noises coming out of your aircon unit.

5) Electrical malfunctions can lead to serious damage to your aircon unit.

Pro 338 Reminder: If you feel that something goes wrong with your aircon unit, immediately call your nearest professional aircon servicing company. This will help you avoid more costly repairs and will even allow you to make more time being productive rather than thinking about what to do with your ‘not-so-cooling’ aircon unit.

Reasons why you have a faulty aircon condenser:

1) Abnormal discharge pressures

If the aircon unit develops abnormal discharge pressures or fails to maintain the required pressure, it may lead to aircon unit failure. Also, if the compressor’s pressure does not maintain the level stated in the manual, it may lead to a condenser failure.

2) Refrigerant leaking within the aircon condenser

The condenser is linked to the indoor unit through a line that allows the refrigerant to circulate. If the coolant begins to leak through cracks or holes, the compressor will have difficulty pumping the refrigerant through the lines effectively. A professional aircon servicing company should be contacted immediately for service. Adding too much or the wrong type of refrigerant may destroy the compressor, and refrigerant sales to non-licensed individuals are restricted. Therefore, it should always be handled by licensed professionals.

3) Electrical system failure


Malfunctioning electrical components within an aircon compressor can cause it to stop working. The condenser powers the motor, fan, and compressor using electricity. If the aircon unit makes a hissing or clicking noise after it turns on, the electrical relay switch may have worn out. Having the switch replaced will get your air conditioner back in action.

4) Dirty coils and clogged suction lines

When dust, debris, and other pollutants accumulate on the condenser coil, the condenser cannot adequately discharge heat. This forces the compressor to run continuously to cool the home. When the aircon unit’s refrigerant suction lines get clogged, it is essential to have a professional aircon servicing company correct the aircon issue. If the problem is not handled, the compressor’s increasing pressure and temperature levels will cause overheating, and the aircon compressor may fail.

When to repair your aircon condenser?

1) Dirty condenser

If your condenser is covered with dirt or plants, give it a thorough cleaning, removing anything that’s blocking or interfering with the aircon unit.

2) Bad condenser relay switch

Typically, an easy fix is swapping out this broken part of the aircon unit with a new one.

3) Bad run capacitor

Another easy repair maybe swapping out this faulty component.

4) Faulty Motor

If the motor is faulty, it will need to be replaced but check your manual for the correct replacement product; otherwise, you risk your aircon unit experiencing more damage.

5) Dirty Coil

Cleaning debris or dirt from the coil is another simple fix that can improve your unit’s capability.

When to replace your aircon condenser?

1) Damaged coil

Repairing a damaged coil can take a significant amount of time and labor, which makes it quite expensive unless your coil is still under warranty. If not, it’s usually recommended that you replace the entire aircon unit.

2) Blockage

Any blockage within your aircon unit means there’s a major aircon issue and that your condenser needs to be replaced. Though depending on the damage caused by this blockage, you may have to replace more than the condenser itself.

3) Leaks

Since it’s not possible to replace condenser seals or tubes, you’ll need to replace the entire condenser, should it be leaking excessively.
