1. Long Hours of Running

Your aircon might be running for over 24 hours which can result in overheating. Do give it a break to to cool it down.

2. Low Refrigerant

Low refrigerant levels cause the aircon to not function optimally, which can result in overheating. When the refrigerant level is too low or there is a leak in the system, your AC may struggle to remove heat from your home effectively. This extra strain can cause the compressor to overheat. If you have recently filled the refrigerant gas then possibly there might be a leakage which needs to be fixed by professional service.

3. Condenser Placement

The condenser must be placed outside your house in an open area, for the heat to be released to the atmosphere. Placing the condenser in a congested area can often cause overheating because the heat from condenser is not released efficiently.

4. Bad Or Dirty Air Filters

One of the most common reasons for air conditioner overheating is dirty or clogged filters. Air filters are responsible for trapping dust, dirt, and other particles, preventing them from entering the system. When filters become clogged, they restrict airflow, causing the air conditioner to work harder to cool the room. This increased workload can lead to overheating. Regularly cleaning or replacing air filters is essential to maintain proper airflow and prevent overheating.

5. Clogged Or Broken Evaporator Coils

The condenser coils in your outdoor unit are responsible for releasing heat absorbed from your home. When these coils become covered in dirt, debris, or vegetation, they can't effectively release heat, causing the system to overheat. Regularly cleaning the condenser coils or ensuring there is proper clearance around the outdoor unit can help prevent this problem.
