Air Conditioner Not Cooling? Here Are 5 Tips to Help

Although air conditioners are one of the most reliable appliances to beat the heat, these appliances can get into a lot of trouble, too. And nothing is more inconvenient than having an air conditioner that does not release cool air in the middle of a very hot day.

Some cases may be temporary and can be easily resolved within minutes, but if this is a common problem with your air conditioning system, it could already be caused by other pressing reasons.

Here are the top reasons why your air conditioning unit is not blowing cold air.

1. Air conditioner is not receiving enough power

Is the aircon not cold? There could be something wrong with how your air conditioning unit was installed in the first place. The power source is one of the first and most common reasons for failing your air conditioning unit to not release cold air. Unfortunately, this problem is not easily detected if you are not a qualified electrician or aircon specialist. Temporarily, you can first check if your AC unit is properly plugged into the outlet. Otherwise, it’s best to simply contact your aircon servicing company to check your power source and whether it is causing your aircon to not blow cool air.

2. Thermostat problems

The thermostat is the brain of your air conditioning system. If it is not working properly, it can cause your aircon unit to malfunction. To check if your thermostat is the problem, set it lower than the current room temperature and see if the air conditioning unit turns on. If it does not, then there might be something wrong with your thermostat that needs to be checked by an aircon specialist. It’s also important to make sure your indoor unit is installed away from direct sunlight. This will help your air conditioning unit cool the room faster.

3. Low refrigerant levels

If you have been using your air conditioners for a long time now, it is likely that their refrigerant levels have already depleted. You will usually see early signs of this in your aircon’s evaporator coil. Ice will usually build up around that area.

When this happens, air cannot properly circulate inside the unit which then results in warm air being released instead of cool air. This problem can only be resolved by qualified aircon specialists as they are the ones who know how to properly handle and recharge air conditioners with refrigerants.

4. Dirty air filter

One of the most common reasons for ACs not blowing cold air is a dirty air filter. When air filters are filled with dirt and dust, air cannot flow smoothly and efficiently inside the air conditioner. As a result, your air conditioning unit has to work double-time which then causes it to overheat, and eventually break down. To avoid this from happening, make sure to regularly check and clean your air conditioner’s air filters at least once every month.

5. Clogged drainage pipe

Your air conditioning unit has a drainage pipe that helps remove water condensation from the unit. But over time, this pipe can get clogged with dirt and other particles which can cause water to build up and leak inside the air conditioner. When this happens, it can damage the aircon and cause it to malfunction. To avoid this, make sure to regularly check your air conditioner’s drainage pipe and clean it as needed. You can likewise call an aircon servicing company for an aircon chemical wash, especially if it has been a while since your aircon was thoroughly cleaned.


How to make air conditioning unit cooler?

If you air conditioner is not blowing cool air, there are a few things that you can do to try and fix the problem.

1. Check the air filter and clean it if needed

Cleaning the air filter is pretty simple to do at home. Just remove the air filter from the air conditioner and wash it with soap and water. Once it is clean, make sure to dry it completely before putting it back in place.

2. Check the thermostat settings

As mentioned earlier, the thermostat is the brain of your air conditioning system. So if it is not working properly, it can definitely affect how your air conditioner functions. The first thing that you can do is to check if the thermostat is set to cooling mode. If it is, then try adjusting the temperature setting and see if that does the trick.

3. Inspect the air conditioner for any dirt or debris

If there is dirt or debris blocking the air vents, it can definitely prevent air from flowing properly. So make sure to check the air conditioner unit and clean it as needed.
