There’s nothing worse than a hot, sticky day with your aircon just not doing its job. You sit there, feeling the heat, hoping that it’ll magically start working, but nothing happens. Don’t sweat it – aircon problems are more common than you think, and they usually have easy fixes. In this blog, we’ll walk you through some of the most common reasons your ac might not be cooling properly and what you can do to fix it. And if all else fails, we’ll let you know when it’s time to call in the pros for aircon repair.
Aircon repair reasons
1. Clogged air filters
One of the most common culprits of poor cooling is a clogged air filter. Over time, dust, dirt, and debris build up in your aircon’s filter, restricting airflow and making it harder for your system to do its job. When the airflow is blocked, your aircon will struggle to cool your space efficiently.
How to fix it: The good news is that this one’s a quick fix. All you need to do is turn off your aircon, remove the filter (usually located behind the front panel), and give it a clean. You can vacuum the filter or rinse it with water (just make sure it’s completely dry before putting it back). Aim to clean or replace your filter every 1-3 months, depending on how often you use your aircon. If the filter is really clogged or damaged, it might be time to get a new one.
2. Low refrigerant levels
Your aircon uses refrigerant to cool the air, and when the refrigerant levels get low, it can’t cool as efficiently. This can happen if there’s a leak in the system, or if the refrigerant hasn’t been topped up in a while. If your AC is blowing warm air or just not cooling at all, low refrigerant could be the issue.
How to fix it: Unfortunately, this isn’t a DIY fix. If you think your refrigerant levels are low, it’s best to call in the pros for aircon repair. A technician can check the refrigerant levels, top it up, and check for leaks. Low refrigerant can also cause other issues with your aircon, so it’s important to get this checked out sooner rather than later.
3. Dirty coils
Your aircon has two coils – an evaporator coil inside and a condenser coil outside. These coils play a huge role in cooling your home. Over time, both coils can get dirty, which reduces the efficiency of your ac and makes it harder for it to cool effectively.
How to fix it: To clean the coils, you’ll need to turn off your aircon and carefully clean the evaporator coil inside and the condenser coil outside. Use a soft brush or cloth to remove dirt and dust. If you’re unsure how to do this or don’t feel comfortable cleaning the coils yourself, give your local aircon repair expert a call. They can clean the coils professionally and get your aircon back to its best.
4. Broken thermostat
If your aircon isn’t cooling properly, it could be because the thermostat is malfunctioning. If the thermostat is set incorrectly or is broken, it won’t tell your ac to cool properly. Sometimes, your aircon may be running, but it just doesn’t seem to be cooling to the right temperature because the thermostat is giving wrong readings.
How to fix it: Check your thermostat settings first. Make sure it’s set to “cool” and the temperature is lower than the room temperature. If everything looks good but your aircon still isn’t cooling properly, it could be time to replace the thermostat. If your thermostat is outdated or faulty, a new one could make a big difference in how well your aircon works.
5. Blocked ducts
Blocked or closed ducts are another common reason why your air conditioning might not be cooling as effectively as it should. If there’s a blockage in the ductwork, the cold air won’t be able to reach every part of your home, leaving certain rooms feeling warmer than others.
How to fix it: First, check to make sure that all your vents are open and clear. Sometimes, vents get blocked by furniture or dust, preventing air from flowing freely. If you think there’s a deeper issue with the ductwork, it’s time to call in a professional aircon repair service. A technician can inspect your ducts for blockages, leaks, or damage and fix any problems to make sure your system is working at full capacity.
6. Faulty fan
The fan inside your aircon is responsible for blowing cool air into your home. If the fan is broken or malfunctioning, your aircon won’t be able to distribute the cool air effectively. This can make your aircon seem like it’s just not cooling well enough.
How to fix it: If the fan blades are damaged or the fan motor is faulty, you’ll need professional aircon repair. A technician can inspect the fan, repair any issues, and get your aircon blowing cool air again in no time.
7. Dirty condenser
The condenser unit (located outside) is responsible for releasing heat from the air, which is an important part of the cooling process. If the condenser is dirty or blocked by debris like leaves or dirt, it can’t release the heat properly, which affects your aircon’s ability to cool.
How to fix it: Turn off your aircon and inspect the condenser for any debris or dirt. Clear away any leaves, branches, or dirt that might be blocking the condenser. Be careful not to damage any of the components while cleaning it. If you’re not sure how to do this safely, give your aircon repair service a call. They can clean the condenser for you and make sure it’s running properly.
8. Aging unit
Like everything else, air conditioners have a lifespan. If your aircon is old and hasn’t been serviced regularly, it might just be time for a replacement. Over time, parts wear out, and it can become harder for your system to cool your home effectively.
How to fix it: If your aircon is more than 10 years old and you’re noticing consistent problems, it might be time for a replacement. A new, more energy-efficient model can cool your home better and save you money on energy bills.

While some of the issues mentioned above can be fixed with a little elbow grease, there are times when calling in a professional is the best option.
