We give you the necessary information to understand why the air conditioner does not cool enough and what to do to solve it.

There are several reasons why an air conditioner does not cool, not only the problem is the gas. In fact, it sometimes happens that the air conditioning does not cool and it has gas.

The first thing that is usually checked for this problem is the gas, but there are many reasons why an air conditioner does not cool. In this article, we will tell you why a split air conditioner does not cool enough or does not cool at all and how to fix it.

In addition, we give you information about this same problem but in portable air.

Why does the split air conditioner not cool enough?

Many times this device usually works well for a while but suddenly we notice that it begins to have cooling failures. We tell you why the air conditioning no longer cools as like as before.

Lack of gas

It is one of the main causes of the lack of cold in an air conditioner; this may be due to a leak from an error in the installation or a problem in a line.

Faults in the external exchanger

When the air conditioning does not cool, it is important to check the external unit of the device. It may happen that the exchanger is clogged by accumulated dirt and does not allow the proper functioning of the equipment.

When this is the problem, we notice that the air conditioning does not cool well or its temperature is lukewarm. It is recommended to clean this element during season changes.

Start Capacitor

In case of compressor or fan failures, the air conditioner will not cool well. When there are problems with the fan, we can easily tell because it doesn’t move.

Impeller

When there are faults in the compressor condenser, the fan runs correctly but the compressor stalls. In these cases, we observe that the air conditioning does not cool and only ventilates.

Indoor or outdoor fan

Faults in these elements are usually due to damage to the condenser (which prevents the fan from moving) or breakage in the fan, which produces vibrations and, as a consequence, the air conditioning does not cool sufficiently.

On the other hand, it may be a fault in the fan motor and, in this case, it must be replaced or checked that it is not stuck.

Dirty filter

Another answer to why the air conditioner does not cool well can be the dirt accumulated in the filters. This causes a decrease in gas compression and, in turn, the vent begins to operate incorrectly.

When this happens, the electrical consumption increases and the equipment can stop. For this reason, it is important to maintain the air conditioner regularly, using a brush, detergent and water (don’t forget to let it dry before replacing it).

Dirty indoor fan

When the filters are not cleaned regularly, the fan tends to collect dirt. This alters the operation of this element and therefore the air conditioning does not cool properly.

As we have seen, the answers to why the air conditioner does not cool well are diverse. There are other causes (although these occur less frequently) such as compressor failure, expansion valve failure, damage to the electronic board, wrong remote control configuration.

In any case, it is always better to contact a specialist to identify why the air conditioner is not cooling and find the best solution.

How to fix a split air conditioner that does not cool?

As we said, it is advisable to contact a technician to find a solution when a split air conditioner does not cool enough or does not cool at all.

In any case, it is essential that you review the configuration of the remote control and, if in doubt, refer to the user manual. Many times the problem can be fixed with something very simple. You can check also how to use the air conditioning in winter

On the other hand, keep in mind the cleanliness of the filters of the device: due to its dirt, the air conditioning does not cool well and only ventilates. It is important that you maintain the appliance properly and regularly: you just have to open the casing of the appliance, remove the filters, wash them with soap and water and let them dry in the open air before replacing them.

In addition to these two tips, it is important that for good home air conditioning you take into account other points:

  • Proper insulation of the house, keep windows and doors closed to prevent cold air leaks. On the other hand, it is important to check the sealing of windows.
  • Close blinds and curtains in the hottest hours to prevent the heat of the sun from increasing the temperature in the home. In this way, we increase the performance of the air conditioning.
  • Maintain a constant temperature, it is convenient that you are not raising or lowering the temperature of the device continuously.

Why does the portable air conditioner not cool enough?

When a portable air conditioner does not cool well, the causes are usually similar to those of the splits malfunctioning.

Lack of gas charge

When the portable air conditioner draws air but does not cool, it may be due to a lack of refrigerant gas.

Dirty filters

As in the splits, the portable air conditioner does not cool well if its filters have accumulated dirt and dust. With its clean filters, the motor is not overloaded, energy consumption is lower and the air is much cleaner and cooler.

Dirty Fan

When the filter is dirty, it can cause dirt in the fan.

Dirty exchanger

This part may have dust accumulation and, in this case, the portable air conditioner does not cool enough and only ventilates. Regular maintenance is important to prevent failure.

Start capacitor

When there is a fault in the capacitors that make the appliance work, it stops cooling.

Device with low frigories

The air may have lower frigories than those needed to air-condition the environment. When buying one, take into account the dimensions of the room to be cooled, the lighting, the number of doors and windows, etc.

How to repair a portable air conditioner that does not cool enough?

If the portable air conditioner does not cool properly, check its filters and clean them, if necessary.

Also check the insulation of the refrigerated room: sometimes a good seal or weather stripping on doors and windows can solve the problem. Another factor to take into account (and not a minor one) is the remote control, since the new air models tend to be more sophisticated and have more options.

This means that we do not understand some modes of air configuration and the cooling of the environment is hindered. Finally, pay attention to the number of air coolers, as sometimes they are not enough for the room we want to cool.

If the problem is not related to dirty filters, the amount of frigories in the appliance, poor insulation from the environment or errors in the remote control configuration, you should contact a specialist to identify why the portable air conditioner does not cool.
