Got air conditioner repair issues?
Keep your air conditioner running smoothly with our expert tips on preventing and fixing common repair issues.
Sometimes, even the best ACs need repairs
Air conditioning systems are essential for maintaining comfort in modern homes, especially during Australia’s scorching summers. A well-functioning AC keeps your indoor environment cool and pleasant, but like any appliance, these systems are prone to wear and tear over time.
From minor annoyances like clogged filters to more serious issues such as refrigerant leaks or electrical failures, problems can develop if maintenance is neglected. Identifying these issues early is crucial—not only can it save you money on costly repairs, but it also helps extend the life of your system.
Some common air conditioner problems may start with subtle symptoms, such as reduced airflow or fluctuating temperatures, and if left unresolved, they can escalate into major malfunctions. Waiting until your AC breaks down can result in unbearable heat and expensive emergency repairs. Regular upkeep allows homeowners to detect warning signs, perform small fixes, and avoid larger complications.
Common air conditioner repair issues you need to know about
Refrigerant leaks
If your air conditioning system is blowing warm air or struggling to cool your home, a refrigerant leak could be the culprit. This issue often occurs due to cracked pipes, wear and tear, or poor installation, leading to reduced refrigerant levels. Not only does this impact cooling performance, but it can also damage the compressor over time. To prevent refrigerant leaks, it’s essential to schedule regular maintenance and get refrigerant levels checked by a qualified technician.
Clogged filters
Weak airflow and rising energy bills are often telltale signs that your air conditioner’s filters are clogged. Dust, dirt, and pet hair tend to build up over time, restricting airflow and forcing the air conditioning system to work harder. This not only decreases energy efficiency but also puts unnecessary strain on the air conditioner. To avoid this problem, it’s recommended to clean or replace your filters every one to three months, depending on usage or according to the manual.
Faulty thermostats
When your air conditioning system refuses to turn on or shows an incorrect temperature, the thermostat may be at fault. This issue can arise from dead batteries, incorrect settings, or worn-out sensors. Faulty thermostats not only waste energy but also make it difficult to maintain comfortable temperatures in your home. You can prevent these issues by checking the settings regularly and replacing batteries as needed. If problems persist, it may be time to replace the thermostat.
Dirty or blocked condenser coils
If your air conditioner is overheating or struggling to cool, dirty or blocked condenser coils could be to blame. Outdoor coils are prone to accumulating dirt, leaves, and debris, which restricts heat transfer and reduces cooling efficiency. This forces the system to consume more energy, shortening its lifespan. Cleaning the coils once a year—or more often if the unit is outdoors—will help maintain performance and prevent unnecessary wear. Also, consider clearing the area of foliage.
Drainage problems
Water leaks or puddles around your indoor unit are often signs of drainage problems. Clogged or disconnected drain pipes can block the flow of water, leading to water damage and potential mould growth in your home. Regular maintenance of your air conditioning system can help you catch these issues before they escalate into more serious issues. Additionally, checking the drain pipes for blockages ensures that the system can expel moisture efficiently and prevent further damage.
Electrical failures
Electrical problems are another common reason air conditioning systems suddenly stop working. Common electrical issues such as faulty wiring, blown fuses, or malfunctioning capacitors can disrupt the system and prevent it from running. Ignoring these issues can lead to more severe kinds of damage over time. Also, scheduling an annual electrical check with a licensed air conditioning technician ensures that all connections are secure and your system stays in good working order.
