Keep reading for cool relief.

Key Takeaways

  • Dirty or blocked parts like air filters and condenser coils make your aircon work harder, leading to poor cooling. Regular cleaning can prevent this.
  • Low refrigerant levels, caused by leaks, reduce your aircon’s ability to cool. Professionals need to fix leaks and refill the coolant for better performance.
  • Choosing the right size of the aircon unit is important. Too small won’t cool enough, while too big can cause humidity problems and wear out quickly.
  • Electrical issues, including problems with wires, motors, or capacitors, can stop your aircon from cooling properly. Check these parts if there’s an issue.
  • Regular checks and maintenance by professionals like Billy Aircon help keep your air conditioning system running efficiently and can extend its lifespan.

Common Reasons for Inefficient Aircon Cooling



Your aircon might not cool well because it’s dirty or broken inside. Common issues include clogged filters, a faulty temperature control device, low coolant, blocked cooling fins, an old compressor, and holes in the airflow system.


Dirty Air Filters

Dust and pet hair clog air filters, making your aircon work harder. This means it doesn’t cool as well. Cleaning them every month keeps your air flowing right and your room cooler.

Faulty Thermostat

Your aircon isn’t cold, and you’re puzzled. A faulty thermostat might be the culprit. This device tells your AC when to cool and when to stop. If it’s not working right, your unit won’t know what to do.

It could run non-stop or not cool at all.

Imagine setting your thermostat to a chilly 22 degrees in Singapore’s heat, but the room stays warm. The problem? The thermostat’s settings are off or it’s broken. Whether the fan is stuck on ‘ON’ causing lukewarm air or it simply doesn’t kick start the cooling cycle – both scenarios mean trouble for your comfort.

Billy Aircon knows this well. They see thermostats causing no end-of-cooling woes across Singapore homes every day. Quick fix? Check if settings are correct: ‘AUTO’ for the fan ensures bursts of cold instead of continuous mild airflow; make sure set temperatures are realistic given our tropical climate.

Still no luck? Your AC may turn on but fail to deliver that refreshing blast of cold air you crave, signaling it might be time for a professional look at that stubborn thermostat – before Singapore’s next hot streak hits hard.

Low Refrigerant Levels

Low refrigerant levels spell trouble for your aircon’s cooling ability. Refrigerants are crucial because they absorb heat from the inside and release it outside, keeping your space cool.

If the level drops, caused often by leaks, this process slows down significantly. You might hear hissing or bubbling noises and see ice on the coils as signs of a problem.

Billy Aircon has fixed many units with these symptoms in Singapore since 2003. Their experts say spotting uneven cooling across rooms also hints at low refrigerant. To fix it right, a professional needs to find the leak, repair it, and refill to the correct level — tasks Billy Aircon handles daily.

Don’t let low refrigerant keep you sweating; getting help ensures your aircon cools effectively again.

Blocked Condenser Coils

Blocked condenser coils are a big reason your aircon isn’t cold. Dirt and debris stop the coils from doing their job – releasing heat outside. If these coils get clogged, your air conditioner works harder but can’t cool your space effectively.

Billy Aircon knows cleaning these outdoor unit parts is crucial for chilly air. Without regular cleaning, the dust makes it impossible for your aircon to work right. This leads to no cooling or weak cold air from your AC unit.

Keep those condenser coils clean to avoid a hot, uncomfortable room.

Worn Out Compressor

A worn-out compressor is a big reason your aircon does not cool. This part pumps refrigerant through the system, crucial for pulling heat out of the air. If it fails, your unit can’t make cold air.

You might notice your AC doesn’t feel as cold or stops cooling altogether.

Billy Aircon knows this issue well. They often fix compressors that don’t work right anymore. If your AC isn’t getting cold enough, especially on hot days, chances are the compressor might need checking or replacing.

Without a good compressor, your air conditioner just won’t do its job.

Leaky Ductwork

Leaky ductwork in your aircon system means cool air escapes before it reaches you. This makes your aircon not cold enough, even on hot days. At Billy Aircon, 25 years of fixing such issues show us this problem is common but fixable.

Professionals can repair damaged ducts to ensure proper airflow and cooling.

Leaks or holes in the ductwork force your AC to work harder. This leads to higher energy bills and a room that’s never quite cool enough. Our experts at Billy Aircon have seen cases where simple repairs made a big difference in cooling efficiency.

Ensuring no leaks are present is crucial for an air conditioner not cooling as expected. Fixing these issues brings back the chill you miss on those warm nights.

Choosing the wrong size aircon for your space can lead to big problems. If it’s too small, it won’t cool enough, making hot days unbearable. Your AC will work harder and use more energy, but still not reach the cool comfort you want.

This means higher electricity bills without the benefits of a well-cooled room.

On the other hand, an aircon that’s too big cools fast but doesn’t remove humidity properly. You’ll feel clammy instead of comfortable. It also turns on and off too much, which wears it out faster and hikes up repair costs over time.

So getting the right size is crucial for both comfort and keeping costs down.



Electrical Issues



Electrical troubles might be why your aircon’s cooling power has dropped. These can range from small wire problems to big issues with your aircon system’s motors or capacitors. Wires can become loose, frayed, or damaged over time.

Motors and capacitors help start the unit and keep it running. If they fail, your unit won’t cool properly. It’s smart to check these parts if your air-con struggles on hot days…

Frozen Evaporator Coils

Your aircon is not cold because of frozen evaporator coils. This happens when air cannot flow properly, making the system work harder and causing ice to form on the coils. Signs include frost on the outside tubing and less cool air in your home.

Your energy bills might go up too.

To fix this, turn off your AC to let the ice melt. Check for clogged air filters or blocked airflow – these often cause freezing. For leaks or constant short-cycling problems, call Billy Aircon experts.

Regular checks can prevent future freeze-ups, keeping your space cool and comfortable all year round.

Aging Aircon System

An aging aircon system loses its cooling power due to worn-out parts. Parts like filters, ducts, and compressors gather dirt or wear down with time. This makes your AC less cold. Your system might also leak water or make strange sounds.

Regular cleaning helps but can’t fix all the problems in an old air conditioner.

Billy Aircon knows that older systems struggle on hot days more than newer ones. Sometimes, your room won’t cool down enough no matter how long the AC runs. These signs mean your aircon is too old and might need a check-up or maybe it’s time for a new one.

Troubleshooting Your Aircon Unit

Your aircon unit might not be cooling your room as it should. This can be frustrating, especially on hot days. Here’s how you can troubleshoot your aircon to find out what might be wrong.

  1. Check the thermostat settings first. Ensure it’s set to “cool” and the temperature is lower than your room’s current temperature.
  2. Inspect the air filter next. A clogged filter restricts airflow, making cooling difficult. If it looks dirty, clean it or replace it with a new one.
  3. Clear any debris around the condenser unit outside. Leaves, dirt, and other obstructions can block airflow and affect performance.
  4. Look at the refrigerant levels. Low refrigerant means your aircon can’t cool air effectively. You’ll need a professional from Billy Aircon to refill it.
  5. Examine the condenser coils for blockage or damage. Dirty or damaged coils struggle to release heat from your system.
  6. Test the compressor by listening for unusual noises or checking if it’s running hotter than usual.
  7. Inspect ductwork for leaks or tears where cool air might escape before reaching your room.
  8. Show sizes matter for aircon units too small or too large for a space won’t cool efficiently.
  9. Find frozen evaporator coils? This could mean airflow problems due to issues like dirty filters or low refrigerant.
  10. Age plays a role—older systems may not cool as well due to wear and tear over years of service.

If after these steps your AC still doesn’t cool enough, calling in professionals from Billy Aircon ensures you get expert help fast and efficiently. They have the tools and experience needed to diagnose and fix more complex issues beyond basic homeowner troubleshooting abilities, helping keep your home comfortable all year round

The Lifespan of Your Aircon



Your aircon won’t last forever. Knowing when to fix it or get a new one is key. Billy Aircon can help figure out the best step for you.

Repair or Replace: Making the Right Choice

Figuring out if you should repair or replace your aircon can save you a lot of money and trouble. If your AC isn’t cooling well, seems less cold than it used to be, or isn’t producing cold air at all, first consider its age.

Air conditioners last about 10-15 years in Singapore’s climate. Repairing might be the way to go for newer units experiencing minor issues like dirty filters or a faulty thermostat.

Big problems like a worn-out compressor or leaking ductwork in an older unit suggest it’s time to replace.

Cost plays a big role too. A simple guideline—calculate if repair costs are more than half the price of a new unit. High expenses on old systems aren’t worth it when modern aircon offers better efficiency and lower electric bills.

Thinking about upgrades? Today’s models suit Singapore homes better by matching room sizes precisely and adjusting to our hot weather without overworking themselves.

1. Why isn’t your aircon cold?

Your AC might not be cooling well for several reasons like it’s full but not cold, there’s a lack of maintenance, or the unit is old and inefficient. In Singapore’s heat, even after cleaning, if your LG air conditioner or any other brand isn’t cooling enough on hot days, it could signal a serious issue.

2. What causes an air conditioner to stop cooling?

Several factors can cause your aircon to blow warm instead of cool air: blocked filters, low refrigerant levels, faulty compressors, or even electrical issues. Each problem stops the AC from producing cold air effectively.

3. How do you fix an AC that isn’t cooling enough?

Start by checking if it’s something simple like a dirty filter or settings error. If these don’t work and your split AC still isn’t cooling enough—or worse—your new unit suddenly stops working; calling in professionals like Billy Aircon ensures you get back to enjoying cool air quickly.

4. When should you repair vs replace your aircon?

Compare costs and benefits carefully… A rule of thumb? If repair costs exceed half the price of a new system—or if your unit is over 10 years old and constantly needs fixes—it might be time for an upgrade.

5. Can regular servicing prevent my AC from not getting cold enough?

Yes! Regular checks keep everything running smoothly; they can spot issues before they escalate into bigger problems where your ac turns on but no cool air comes out… It saves money in the long run too!
