The AC condenser units are among the main parts of cooling AC systems. It is the outside unit that usually sits on a roof or in a yard. Many issues may affect how an AC condenser works, with all of these problems affecting how the AC system functions.
This article will explain all the things you should know to make sure your AC condenser is working, along with what you should do when it starts experiencing problems.
What Is an Aircon Condenser?
An AC condenser or condenser is an outdoor part of a heat pump or air conditioner that collects or releases heat (depending on the time of the year).
Both the heat pump and split-air conditioner condensers feature the same main or basic parts. The condenser cabinet houses a compressor, condenser coil, a fan, and various controls. The condenser coils are either made of all-aluminium tubing, which allows for rapid heat transference, or copper tubing.
What Role Does an Aircon Condenser Perform?
The condenser in an AC system receives high-pressure gas from a compressor, converting the gas into a liquid. This is made possible by heat transfer, which relies on a principle whereby heat will move from warmer to cooler substances.
When the refrigerant starts flowing through a condenser, the fins in the condenser allow heat transference to the “surrounding air”. The condenser also features a fan over the top that makes sure the heated air is cooled off quickly, enabling these processes to continue. Once the refrigerant temperature drops below its “saturation temperature”, it will turn back into a liquid.
What Occurs When An AC Condenser Is Not Functioning The Way That It Should?
A malfunctioning condenser can result in several problems. One of these examples includes when the AC stops producing enough cool air, which results in an increase in energy bills and less comfort and efficiency. It is important to note that this could also be an indication of a compressor issue or even a refrigerant leak. If you are suspecting either, make sure you call our technicians as soon as possible.
If the condenser is blocked, it can result in something known as short-cycling, where the system cycles off and on rapidly, which means the AC system cannot function properly. This eventually leads to a lot more wear-and-tear that the system can withstand, often leading to a complete yet premature breakdown.
When you expect cooled air, and instead your aircon is blowing out lukewarm air, the AC condenser needs to be checked for a defect or blockage to find out what is causing a restriction in airflow.
If the flow of liquid or gas is interrupted, your system can no longer operate at optimum efficiency. When the system can no longer release heat, your AC system will build up and eventually cause the rest of the parts to increase in temperature to a stage where the components start to burn and emit a foul smell when you turn your AC on.
This is one of those serious issues which may result in having to replace several parts in the system since they may have melted and no longer operate.
What Should You Do Next?
There are 2 primary procedures used to detect gas leaks in A/C condensers. The first is used by a mechanic at a dealership, while the other procedure is used in homes. Since we know you probably do not have the tools and equipment to diagnose the problem professionally, here are the methods you can use that do not involve leak detectors.
If the condenser has stopped running altogether, only skilled technicians will diagnose whether it is a motor or compressor problem and if parts need repairs or replacements. For any of your condenser issues, contact a qualified technician and have experience with air-con repairs.

Tips To Prevent Air Condenser Breakdown
Regular maintenance by a professional AC specialist is one of the best ways to keep your system protected from potential problems such as a “bad condenser”. During AC maintenance, the technician will inspect and clean the system. The fins on a condenser that distribute the heat from your refrigerant often get bent. A qualified technician will straighten the fins and clean out the coils. From here, the technician can advise you if any other issues require attention.
