Aircon blowing hot air? This experience is confusing because air conditioners are supposed to keep your rooms cool and the air pure. Fundamentally, your air conditioner should not be blowing hot air. There are a few reasons why this might be, and it’s important to understand the causes and take the necessary steps to ensure that the problem doesn’t persist.
This article will answer the question: why is your air conditioner blowing hot air?
Should I be worried about hot air?
Yes. If your aircon is blowing hot air, this is indicative that something is wrong with your air conditioner. The problem could be easily fixable or a sign that something more severe is happening. To understand what could be wrong with your air conditioner, you should ensure that you have followed the maintenance recommendations.
Why is my aircon blowing hot air?
One of the main reasons your aircon may be blowing hot air is that maintenance has not been as regular as it should be. Maintenance, as with any appliance, is key to ensuring that it works optimally for as long as possible. Maintenance doesn’t necessarily need to be carried out by a professional. There are steps that you can complete yourself, including paying attention to your air filter.
- Incorrect air filter maintenance
The air filter in your air conditioner is the component protecting those in your space from harmful particles. Keeping your air purified is one of the primary functions of an air conditioner, so it is vital to ensure that the filter in the air conditioner is clean.
Your air conditioner will arrive to you with a filter provided, which may be reusable. So you should monitor the condition of the filter as you use it. Surveying the filter before first use is a way to gauge what your filter should look like, so you can identify when it needs changing in the future.
It is recommended that your air conditioner filter is cleaned once a month to ensure that your air conditioner works as it should. This can vary depending on the conditions you live in. For example, if you live in an area with a surplus of dust, you may need to change your filter more regularly.
As stated above, you should endeavour to clean or replace your air conditioner filter once a month to keep the air clean and the machine working properly. But additionally, the air conditioner may start blowing hot air if the dirt is left to build up. This is because the dirt, dust, and allergens will clog your air conditioner and force it to work harder than it should. This will cause your system to overheat. Your air conditioner blowing hot air may be a result of improper maintenance or complete lack thereof.
- There’s something wrong with the condenser coils
Another reason for your aircon blowing hot air could be that the coils have gotten into bad condition. Dirty or blocked condenser coils can have your aircon blowing hot air thanks to interrupted airflow.
- The compressor is damaged
A damaged compressor is the worst-case scenario and should only be repaired by a trained professional. This, rather than causing your system to try and push through dirt in the filters or coils, can cause your system to lose its ability to cool itself. Aside from your aircon blowing hot air, you may also notice it is making odd noises and struggling to start and maintain airflow. These are indicative symptoms that should not be taken lightly and should be addressed immediately.
Ignoring a possibly damaged compressor could cause your system to run continually without cooling your home. This can increase your energy bills considerably if left unchecked.

- The refrigerant is leaking
The refrigerant is another integral component of your air conditioning unit, as it is responsible for absorbing heat and transforming it into cool air for your room. You may have noticed a small amount of water or condensation dripping from your air conditioning unit drain. It should be noted that this is normal. However, if you notice an increase in condensation from the ceiling space or outlets, the refrigerant is probably leaking. This will result in your air conditioner blowing hot air and struggling to generate cold air.
You should hire a professional to evaluate the situation and conduct the necessary repairs if you think your refrigerant is leaking.
Essentially, there are plenty of reasons your air conditioner might be blowing hot air. So it is important to ensure that your air conditioner is regularly maintained and that you contact a trained professional if the issue is more severe.
