Finding out the reasons why your aircon is not cold is important. This is so you can know when it is also time to have a replacement. After all, you need your air conditioner to be circulating cold air efficiently to combat the overwhelming heat. 

 

Reasons Why Your Aircon Is Not Cold

Low on Aircon Gas

The coolant liquid that the AC’s compressor pumps into the evaporator coils is called a refrigerant. One of the benefits of getting a gas top-up is its ability to help cool the warm air in the room. This can be one of the causes for why your aircon does not seem to be cold enough.

Clogged Air Filter

One of the benefits of hiring a professional aircon servicing company is that they effectively clean the air filter from dust and debris. This is because cold air won’t travel easily through your air filter if it is blocked. A good air filter prevents dust and debris from accumulating on all the internal parts of the unit. A poorly maintained filter will contribute to wear and tear and may eventually require significant repair. Your aircon might need to be replaced one or two years earlier than expected.

Filthy Condenser Coils

If the condenser of your aircon is installed outside (e.g. Daikin iSmile Series (Inverter) – SYSTEM 3 AIRCON), dust and other residues may accumulate on it. This can result in poor performance and increased energy consumption. In severe cases, it could even cause early system or component failure. If cleaning your unclean condenser coils doesn’t increase efficiency, it might be time for a replacement.

Clogged Evaporator

A couple of things occur when the evaporator coil gets clogged. If debris gets in, airflow will be reduced, and the coil’s airflow rate will be slowed. Eventually, it can overwork the compressor and the blower motor, causing them to over-amp and possibly fail. This is a good reason why it is important to have regular aircon maintenance. If failed to do so, a costly replacement will be the only option left.

Leakage of Coolant or Refrigerator

It is possible that low air conditioning gas is not due to a low level, but rather to coolant leakage. This is an air conditioning emergency and must be managed quickly by a professional air conditioning company. A leak that took a long time to discover may have already inflicted damage on the compressor. When this happens, it may be necessary to conduct an aircon replacement. One model to consider would be the Mitsubishi Electric Starmex GN Inverter.

Faulty Thermostat

When there is a problem with your manual or programmed thermostat, your aircon won’t be able to adjust to the proper temperature. The thermostat controls how well the air conditioner works. As a result, your air conditioner can’t efficiently cool the room because it isn’t functioning properly. After an aircon servicing, and you still suffer such problems, it might be time for a Panasonic XS Series System 2 aircon replacement.

Faulty Capacitor

To start the compressor, most window air conditioners use a capacitor. The air conditioner may stop producing cold air and instead begin to blow warm air if the capacitor is faulty. It might be necessary to disassemble the unit to access this component because it is inside the unit. A maintenance check should always be done even if there is no obvious indicators of damage. 

Damaged Ductwork

Damaged ductwork is also one of the reasons why an aircon can’t blow out cold air. When this occurs, air may be delivered unevenly or possibly not at all.

Faulty Printed Circuit Board 

A damaged PCB can make the whole air conditioning equipment malfunction. Therefore, if it is damaged, it can cause your aircon to malfunction. Contact a licensed technician to deal with the issue as soon as possible.  

Damaged Thermistor

If your air conditioner has an electronic control system, look at the thermistor in the airflow passing by the evaporator coils. A new thermistor needs to be installed if the component exhibits damage or corrosion.

Damaged Compressor

A faulty compressor can also make it impossible for your air conditioner to produce cold air, though this is less common. This is because it prevents the condenser from spreading refrigerant between the inner and outer units.

Broken Fan

Your aircon’s fan could be broken if it can blow out cold air but doesn’t appear to distribute it in the right directions. Checking the interior unit and listening for any indications of buzzing might be a sign your aircon needs repair or replacement. You may also use a screwdriver to open it but make sure to not damage any other aircon parts. 

Frozen Condenser Unit

If the condenser of the unit is frozen, your air conditioner won’t function properly. This will make it feel like it isn’t cold enough. Engaging with regular aircon maintenance can help prevent this issue from happening.

Many people purchase air conditioning units without understanding how the unit’s size relates to the size of the room they want to cool. For instance, you bought a 1.5 hp split type Daikin (Inverter). A 1.5 hp aircon usually can cool a 22 to 25 sqm room. If you install the 1.5 hp aircon in a 26 to 28 sqm room, it will not be powerful enough to maintain the room at a cool temperature. Which causes most people to think their aircon is not cold enough. In addition, this causes your aircon to work too hard and degrade more quickly.

These issues contribute to the air conditioner not being cold. You may be able to resolve some of these issues on your own. The following steps can help you resolve some of the stated problems. They can also help in avoiding the same issues in the future.

 

How To Fix Your Aircon Not Cold Problems

Here are some methods to fix your aircon that is not cold enough.

Check If Aircon’s Thermostat Is Working Properly

Sometimes the aircon is not cold because the thermostat is not properly set. Check your aircon’s thermostat to adjust to your desired temperature. 

Inspect Your Aircon’s Circuit Breakers

Inspect the circuit box to see if turning on your aircon produces a power trip. Wiring issues can cause both the interior and outdoor equipment to fail to operate effectively. In that case, call an aircon maintenance company to do aircon wiring repair as soon as possible.

Clean Your Aircon Unit’s Filters

One of the main reasons why your aircon is not cold is dirty or clogged aircon filters. It can also result in other air conditioning problems, such as an air conditioner leak, which can increase power usage. 

Check for Signs of Ice Buildup Inside Your Aircon

Ice buildup inside the air conditioner is another potential cause of your air conditioner not being cold enough. Typically, this occurs when the fan blower belt degrades and sustains damage. If so, have an air conditioning company replace it so the problem is fixed.

How To Avoid Aircon Not Cold Issues

According to the majority of aircon manufacturers, aircon should be able to last for a long period of time. So, here are some strategies to make sure your unit is long-lasting:

  • Make sure the air conditioning unit has regular maintenance, ideally once per year. Standard air conditioning repairs, component replacement, and cleaning often make up such maintenance.
  • Even if your installed air conditioner is currently operating without any problems, make sure to get it maintained each month. It will be able to continue operating at its peak level in this manner.

 

When To Replace Your Aircon Unit? 

If Aircon Unit Is Over 10 Years Old

An air conditioner is designed to last for at least 10 years. This is the maximum number of years that it can effectively serve you. That is given the fact that you are performing regular maintenance on it. Thus, it is essential that you give your AC a break if it begins to malfunction after more than 10 years.

Always Needs A Repair

Repair services are not a negative thing, especially if they are actually required. But if your unit has been needing repair frequently, you better think it through. It might require replacement if it continues to have the same issue over and over again. Replacing it with a new one might be a good choice. Rather than spending your money more on repairs and higher power bills due to its inefficient cooling system.

High Electricity Bills

Consider taking your unit to a professional if you noticed an increase in your electricity expenses. If after the repair has been performed and your electricity bills continue to increase, it’s evident that you need a new aircon unit.

Extreme Increase In Humidity

The humidity in your home can be managed and balanced with the help of your air conditioners. A broken unit can cause moisture accumulation on your windows. If this happens, the high humidity level in your home can give you a sticky feeling. This issue can increase the possibility of mould problems. Both of which could create a harmful environment for your family.

Your Room Got Bigger

Your air conditioning systems’ sizes show how much space they can effectively cool and manage. As a result, it will work harder if you expanded your home or added extra rooms but didn’t add any AC units. Resulting in an inefficient system.
