Is your aircon not as cold as you’d like it to be? If so, there are a few reasons why that may be the case. This blog post will explore 14 possible reasons why your aircon isn’t working properly and how you can fix it. Keep reading to learn more!
1. Dirty air filter
Your air conditioning unit might not be blowing cold air because the filter is dirty. Cleaning or replacing the filter can solve this problem. This is one of the maintenance methods that you can safely and easily do from home but will significantly improve the overall performance of your air conditioner.
2. Leaky ducts
Ducts that are leaking air can prevent your AC from cooling the room properly. Leaks in your ducts can be caused by age, wear and tear, pests, or simply poor installation. Fixing any leaks in your ducts will help your AC run more efficiently and cool the room better.
3. Clogged evaporator coil
If the evaporator coil is clogged with dirt, dust, or pet hair, it will not be able to absorb heat from the surrounding air. Cleaning the coil is a simple and effective way to improve air conditioner efficiency. This may be a lot trickier to do by yourself, so it’s best to consult an aircon specialist about this.
4. Blocked condensate drain tube
When the condensate drain tube is blocked, your AC won’t be able to get rid of excess water. If left unaddressed, this can lead to mold and mildew growth in your home as well as damage to your AC unit. To fix this problem, you simply need a special cleaning tool that gets rid of any blockages in the tube. You can find this tool at most home improvement stores for around $30.
5. Worn out air conditioner compressor
If the compressor on your air conditioner isn’t working properly, it will not be able to circulate refrigerant properly. Replacing the compressor is a fairly complex repair that should be done by a professional.
6. Thermostat issues
If your AC isn’t blowing cold air, it could be because the thermostat is set to “heat” instead of “cool.” Another possibility is that the thermostat is not set to low enough. Set the thermostat to “cool” and turn it down to the lowest temperature setting. If this doesn’t work, you may need to replace the thermostat entirely.
7. Incorrectly sized AC unit
Another potential reason why your air conditioner might not be cooling your home effectively is that it’s not the right size for the space. An AC unit that’s too small won’t be able to cool the room properly, while an AC unit that’s too big will use more energy than necessary and may not dehumidify the air properly.
8. Dirty condenser coils
If the coils on your AC unit’s condenser are dirty, it won’t be able to dissipate heat properly. This will cause the unit to work harder and use more energy than necessary. To clean the coils, simply remove them (being careful not to damage them) and spray them with a hose. You can also use a coil cleaning brush or a commercial coil cleaner. Be sure to replace the coils when you’re finished.
9. Refrigerant leaks
Another potential cause of an AC unit not cooling properly is a refrigerant leak. Refrigerant is what helps your AC unit cool the air, so if there’s a leak, the unit won’t be able to do its job properly. A professional AC repair person can fix refrigerant leaks.
10. Fan problems
If the fan on your AC unit isn’t working correctly, it won’t be able to circulate air effectively. This will prevent the unit from cooling your home properly. You’ll need to replace the fan motor or blade to fix this problem.
11. Clogged filter
As we mentioned before, a clogged filter can prevent your AC unit from cooling the room properly. Cleaning or replacing the filter is a simple and effective way to improve air conditioner efficiency.
12. Dirty coils
If the coils on your AC unit are dirty, it won’t be able to dissipate heat properly. This will cause the unit to work harder and use more energy than necessary. To clean the coils, simply remove them (being careful not to damage them) and spray them with a hose. You can also use a coil cleaning brush or a commercial coil cleaner. Be sure to replace the coils when you’re finished.
13. Damaged ductwork
If your home’s ductwork is damaged, it can cause leaks that will decrease the efficiency of your AC unit. If the ductwork is damaged, you’ll need to have them repaired or replaced by a professional.
14. Improperly sized unit
If your AC unit isn’t the right size for your home, it won’t be able to cool the room properly. An air conditioner that’s too small won’t be able to cool the room properly, while an AC unit that’s too big will use more energy than necessary and may not dehumidify the air properly.

Using Your Air Conditioner Efficiently
While “aircon not cold” is one of the most common complaints of people, there is actually a better way to still stay comfortable with your air conditioner without necessarily overworking it.
- Use a programmable thermostat: A programmable thermostat can help you save money by automatically turning the AC off when you’re not home and turning it back on a few minutes before you arrive.
- Upgrade to an energy-efficient AC unit: If your AC unit is more than 10 years old, it’s time to upgrade to a newer, more efficient model. Newer units use less energy and can help you save money on your energy bill.
- Close the windows and doors: To prevent cool air from escaping, be sure to close the windows and doors when the AC is running. Using block-out curtains is also one of the tricks to keep your room cooler while saving on your energy consumption.
- Use fans: Fans can help circulate the cool air from the AC unit and make your home feel more comfortable. This will assist your air conditioner unit in facilitating blowing cold air.
- Keep the AC unit clean: As we mentioned before, a clean AC unit will work more efficiently than a dirty one and will prevent your air conditioning system from not blowing cold air. Be sure to clean the filters and replace it when necessary regularly.
Air Conditioner Maintenance
All these issues can be easily addressed by regular aircon service. This includes regularly washing your air filter, lubricating the outer parts of your AC, and having it cleaned by an aircon professional. Doing all these things can help increase the lifespan of your AC and ensure that it functions properly for many years to come.
There are a number of reasons why your air conditioner is not cooling your home effectively. These include thermostat issues, incorrect AC unit sizing, dirty coils, and refrigerant leaks.
Some of these problems can be fixed easily, while others will require the help of a professional. Regular air conditioner maintenance can also help prevent many of these issues and improve the lifespan of your AC unit.
