Why Your Split AC Isn’t Cooling Properly and How to Fix It
When temperatures rise in the UAE, your split air conditioner becomes essential for daily comfort. But if your AC is running without cooling the room effectively, it’s more than just inconvenient — it’s a sign something needs attention.
Whether you use your unit at home, in an office, or a commercial space, understanding the common reasons behind low cooling performance can help you fix minor issues and know when it’s time to call an expert.
Let’s look at the most frequent causes of poor cooling and how to solve them — plus, when it might be time to consider upgrading to a Super General air conditioner system for optimal performance.
1. Dirty or Clogged Air Filters
Dust and sand are part of daily life in the UAE — and they’re also your AC’s biggest enemy. Over time, air filters collect dust and debris, restricting airflow and reducing cooling efficiency. A clogged filter forces the compressor to work harder, increasing electricity consumption while lowering performance.
How to Fix It: Clean or replace the air filters every 2–3 months, or more often if you live in a dusty area. This simple step can immediately improve airflow and cooling efficiency.
2. Low Refrigerant (Gas) Levels
If your AC isn’t cooling properly or takes unusually long to reach the desired temperature, it could be due to low refrigerant levels. Refrigerant leaks or insufficient gas pressure reduce the system’s ability to absorb heat, resulting in warm or uneven cooling.
How to Fix It: This requires professional attention. Have a certified technician check for leaks, refill the refrigerant, and ensure the system is properly sealed. Reach out to our team for support.
3. Weak or Failing Compressor
The compressor is the core of your air conditioner. It circulates refrigerant and maintains the pressure needed for cooling. Over time, compressors can weaken due to age, overheating, or electrical faults, causing your AC to lose its cooling power.
How to Fix It: If your compressor is making unusual noises or failing to start, contact a professional technician. In some cases, replacing the compressor or upgrading to a Super General inverter split unit may be more cost-effective than repair.
4. Blocked Outdoor Condenser Unit
Your outdoor unit releases the heat absorbed indoors. When it’s covered in sand, dust, or debris, heat transfer slows down, forcing your system to work harder and deliver less cooling.
How to Fix It: Check that the area around the outdoor unit is clean and unobstructed. Schedule a professional coil cleaning to restore efficiency, especially before summer.
5. Incorrect AC Size for the Room
One of the most common mistakes in AC installation is using an undersized unit for a large space. If the AC’s tonnage doesn’t match the room size, it will struggle to maintain temperature — leading to poor cooling, high bills, and faster wear on components.
How to Fix It: Ensure correct load calculation before installation. Super General offers a wide range of ACs:
• Wall Split Units for bedrooms and small offices
• Floor Standing ACs for villas, halls, and open areas
• Ducted Split Systems for large homes or commercial spaces
• Window ACs for compact rooms and budget-conscious cooling
Choosing the right model ensures consistent performance and efficiency. Contact our sales experts to guide you in selecting the right AC for your space.
6. Air Leaks or Poor Insulation
Cool air can escape through gaps in doors, windows, or poorly sealed ducts, forcing your AC to work overtime without cooling effectively.
How to Fix It: Inspect your room or ducts for air leaks. Sealing gaps and ensuring proper insulation can make a noticeable difference in performance and comfort.
7. Lack of Regular Maintenance
Regular servicing keeps your AC efficient and extends its lifespan. Ignoring tune-ups allows minor issues like dirt buildup, loose connections, or low refrigerant to escalate into costly repairs.
How to Fix It: Schedule bi-annual maintenance with a trusted service provider. Super General recommends professional inspection before and during summer to ensure peak efficiency in UAE’s extreme climate.
When It’s Time to Replace Your AC
If your wall split AC is more than 5 years old, frequently breaks down, or struggles to maintain temperature despite servicing, it may be time for an upgrade.
Super General offers a complete range of energy-efficient air conditioners, including:
• Wall Split ACs for homes and offices
• Floor Standing ACs for large villas and halls
• Ducted ACs for centralized cooling
• Window ACs for compact, cost-effective solutions
Upgrading to a Super General air conditioner means better cooling performance, lower DEWA bills with inverter technology, and long-term reliability.
Conclusion
If your wall split AC isn’t cooling as it should, don’t ignore the warning signs. From simple filter cleaning to complex compressor or refrigerant issues, regular maintenance is essential to keep your unit performing efficiently in the UAE’s extreme climate.
