It’s a hot day in Singapore. You switch on your aircon, but instead of cool air, you feel warm air blowing out. Annoying, right? Don’t worry—you’re not alone. Many homeowners face this issue, and the good news is that it’s usually easy to fix. So, let’s go through the common causes and what you should do.
1. Dirty Air Filters
First of all, a clogged aircon filter is the most common reason. Dust and dirt block airflow, which makes your unit blow warm air instead of cool.
Fix it: Clean or replace your filters regularly. Moreover, in Singapore’s humid weather, once a month is best. If you don’t have time, you can always book aircon servicing in Singapore.
2. Low Refrigerant (Gas) Levels
Another common cause is low refrigerant. If your unit runs out of refrigerant, it can’t cool the air. This is often called an aircon gas top-up in Singapore.
Fix it: Therefore, call a professional aircon technician in Singapore to refill the gas and also check for leaks.
3. Dirty or Frozen Coils
In addition, coils can get dirty or even freeze if maintenance is skipped. When this happens, cooling stops.
Fix it: First, turn off your aircon and let the coils thaw. Afterward, schedule a professional aircon chemical wash in Singapore to prevent it from happening again.
4. Thermostat Problems
Sometimes, the problem isn’t with the aircon but with the thermostat. If it’s set wrong or faulty, you’ll only get warm air.
Fix it: To start, check that it’s set to cool mode and a low enough temperature. However, if it’s still not working, it’s best to book an aircon inspection in Singapore.
5. Blocked Outdoor Unit
Finally, don’t forget the outdoor condenser. It needs airflow to release heat. But if it’s blocked by dirt, leaves, or even furniture, it won’t cool.
Fix it: Keep the area clear. Meanwhile, for a deep clean, call an aircon cleaning service in Singapore.
