JAKARTA, KOMPAS.com – Air conditioners are the most reliable equipment to cool and cool the room, especially during hot weather.
However, when the air is hot, AC it doesn’t work properly, aka it doesn’t cool the room. Of course, this condition is annoying and makes the atmosphere uncomfortable.

There are several reasons why the air conditioner is not cold, from refrigerant problems to outdoor or outdoor units. Therefore, it is urgent to repair the air conditioner to make it cold again and prevent greater damage.
Quoted from Rhythm of the Home, Monday (22/5/2023), here are the reasons why the air conditioner is not cold and how to fix it.

Check the setting on your thermostat. If it’s set to “auto”, try setting it to “on” and see if it makes a difference.
When set to “auto” the thermostat sometimes runs the fan without cooling the air so it blows warm air instead of cold.
If nothing changes, a simple reset will do the trick. Different models have different reset procedures, so consult the manual or search online for the procedure.

AC air filter clogged
Furthermore, the cause of the AC not cooling is a dirty or clogged air filter, which blocks the flow of air into the house.
Dust, stuffiness and overall decrease in air quality are the main symptoms to look out for if the air filter is clogged.
If the dirty air filter is not replaced, the evaporating coil will freeze, which slows and eventually stops cold air from entering the house.
Always check filter condition AC and replace every 30-90 days, depending on the condition.

Dirty condenser (outdoor unit)
If the condenser is dirty, you will have the same problem with a clogged filter. Restricted airflow can cause the outdoor unit to work too hard resulting in overheating, which is why the air conditioner is not cooling.
Excessive heat will also increase energy bills without getting cool air.
To fix this, rinse the condenser AC use a gentle spray. Add detergent to the water and use a soft cloth to remove stubborn dirt.
Rinse gently while being careful not to damage the fragile aluminum fins. Remember a clean condenser will perform optimally so it cools faster and provides longer service life.
Also, remember to cover it with weather-resistant material when not in use.

If until now the air conditioner is still not cold, it’s time to contact an HVAC specialist. Below are some possible AC malfunctions that require professional technical skills to repair.
The airway is damaged
Damaged air ducts are also the reason why the air conditioner is not cold. A damaged duct will expel cold air before it reaches your ventilation duct.
HVAC specialists use special tools to diagnose leaky air ducts by measuring the different air pressure levels in the ducts.
Possible causes of leaky air ducts include normal wear and tear, rodents, even poor construction techniques.

Mechanical problem
Condenser AC exposed to harsh conditions and requires regular maintenance to operate optimally.
The condenser fan spins for hours at a time and is usually the first mechanical part to fail. When damaged, the condenser loses its ability to dissipate heat and cool the house.
Another common problem is compressor failure. The compressor’s job is to circulate the refrigerant throughout the outdoor and indoor units.
If damaged, the refrigerant remains inactive so cooling cannot occur. Both parts are too sensitive for self repair.

Refrigerant level

Refrigerant is circulated through the indoor and outdoor units bringing hot air in and replacing it with cold air.
Refrigerant is not meant to be refilled. If the level drops, it is most likely a leak in the refrigerant line, which is ultimately the cause of the air conditioner not cooling.
Here are some ways to detect a leaking refrigerant line:
- Bubbling or hissing sound when the air conditioner is on.
- Ice buildup in refrigerant lines.
- A general decrease in cold air.
- Difficulty cooling the house so it takes longer.
Turn off AC and call a professional if you see these signs. This will prevent damaging the compressor. Leave it to trained professionals and special tools to detect, repair, or replace leaking refrigerant lines.

How to maintain air conditioning units
Keep the AC unit in top condition to avoid things that cause the AC not to cool by following these maintenance tips:
- Cover with weather-resistant material when not in use.
- Replace air filter every 30-90 days.
- Clean the units AC outdoor regularly to prevent clogging of the aluminum fins.
- Keep the area around the condenser neat and clean. Clear bushes and trim overhanging branches.
