Aircon Not Cold?
Here are some reasons why
Aircon Not Cold
There are a variety of air cooling system problems we all commonly encounter. One of these problems is AC units that no longer efficiently fills in cool air in the entire room or perhaps is already blowing in lukewarm or hot air. This is an apparent problem that needs to be fixed as this no longer serves its main purpose and that is to provide cold air. There are several ways to be able to fix this problem and cool your space properly. Tackling this issue will require two different approaches in order to solve it. Some ways may be easy and can be handled by you but there are some instructions that on too complex to understand that needs the expertise of an AC technician. Most of the common causes of the air cooling system’s failure to produce cool air is due to dirty air filter, thermostat setting problems, and accumulation of dirt in the external part of the unit. On the other hand, too technical problems may arise like a faulty condenser fan motor, leaking refrigerant or an overall bad compressor that needs fixing or replacement. If you are able to assess the problem and evaluate that the problem is too complicated to solve by yourself then having a professional do it is better to avoid incurring further problems in the unit.

Checking for Signs of an Aircon that is not Cold
- Inspect the condenser fan motor
The very purpose of a condenser fan motor, which is one of the most essential part of a HVAC system, is to cool the refrigerant gas which then is transformed into cool liquid. That is why its role in the air cooling system is very essential. If the motor is not functioning very well, then the outdoor unit particularly its fan would not be able to scatter heat that eventually means it won’t be able to cool your space.
- Leaking Refrigerant
To be able to understand the problem, one must be able be familiar with the parts of the air cooling system and its process. The refrigerant in particular is a liquid that is responsible for absorbing the heat from the air circulating around the space. When there is an inadequate amount of refrigerant, then there would be inefficiency in absorbing the heat around in order to cool the air. This would be a reason to explain why the AC has an observable inadequacy to cool the room. A reason for the low levels of refrigerant is a leak found inside the system. Possible signs that could decipher that
there indeed is a leakage in the refrigerant are: ice buildup, hissing noise, inability of the unit to cool on hot days.
- Defective Compressor
The compressor is another part that plays an integral role in producing the cool air. It works hand in hand with the unit’s refrigerant which does the circulation between the outdoor and indoor unit. The entire idea concludes that if the condenser is damaged or is not working well then the AC cannot cool air at all. The condenser is a very expensive part, so taking good care of it and having a warranty is very important to avoid necessary expenses.
Solutions to an Aircon that is not Cold
- Temperature Control
If there are any problems with the air cool output produced by the AC unit then the first thing to inspect is its central temperature control which is the thermostat. This part of the AC detects the thermal state of the room and signals the compressor to be turned on or off. To enable to determine this problem, carefully inspect the thermostat, specifically its sensing bulb for any visible presence of bent or rupture. This apparent hardware defect will greatly affect its function to
evaluate the temperature therefore sending a wrong signal to the compressor.
- Fix or replace fan motor
The Fan motor could be another culprit to the problem of inadequate cooling air produced in an AC system. The primary role of a fan motor is to gather air from the cold evaporator coils and recirculate it into the room. If there is inefficiency of air flow output from the evaporator coils then frost formation could build up which eventually hampers further air flow. This can be inspected through opening the AC cabinet and do the necessary checks. Evaluate if the fan motor turns easily and that the blades do not have visible damage. If the damages are irreparable then replacing them is necessary.
- Clean the filter and outside unit
Cleanliness of the air cooling system is one of the reasons why the cooling process is disrupted. A dirty air filter causes several problems which reduces the airflow inside the AC. A clogged up air filter will prevent the circulation of cool air inside the space. This will also affect the evaporator coil which will eventually freeze the part. Another reason would be debris piling up from the condenser found in the outside unit. This would give the unit a hard time to dissipate heat. A solution to the reduction of cold air output is to simply regularly clean these parts in particular to increase the air cooling
