Does your aircon run for hours but still leave the room warm? Many people in Singapore face this problem. If your aircon isn’t cooling, it means something is wrong. Let’s look at the common causes and what you can do.
1. Dirty Air Filters
Dust and dirt block your aircon filters. This reduces airflow and makes your unit work harder. As a result, cooling slows down and power use goes up. With regular aircon servicing in Singapore, filters stay clean and cooling stays strong.
2. Low Refrigerant Gas
Your aircon needs gas to cool. If the gas level is low, the unit may run but not cool. Leaks are common in older systems. A quick aircon gas top-up in Singapore can fix this problem.
3. Clogged Coils
Condenser and evaporator coils can collect dirt. This stops heat from leaving the system. When that happens, cooling weakens, and warm air may come out. A simple cleaning is not enough. A chemical wash in Singapore or a full chemical overhaul clears the dirt and restores performance.
4. Wrong Aircon Size
If your aircon is too small for the room, it won’t cool well. For example, a 9,000 BTU unit is fine for a small bedroom but not for a big living room. An expert in aircon installation Singapore can help you choose the right size.
5. Poor Maintenance
Skipping service leads to blocked pipes, mold growth, and weak cooling. Many in Singapore wait until the aircon breaks down. This costs more in the long run. Book aircon servicing every 3 to 4 months to prevent major problems.
What To Do Next
If your aircon isn’t cooling after long use, don’t ignore it. Start by cleaning filters, checking gas levels, and making sure the unit matches the room size. For bigger issues like leaks, clogged coils, or repeated breakdowns, call an aircon repair Singapore service.
