When you invest in a brand-new air conditioner, the last thing you expect is for it to fail in keeping your home cool. After all, new AC units are supposed to be efficient, powerful, and capable of delivering that sweet chill during Dubai’s scorching summer heat. But what if your new AC just isn’t living up to your expectations?
If your new air conditioner is underperforming, you’re not alone. Whether you’re in Dubai, Sharjah, or Ajman, several people experience the same frustration. Let’s dive into the possible reasons why your new AC isn’t cooling like it should—and when to call the Best AC Repair in Dubai at +971 050-3338786 or visit Al Bahlool Services.
1. Incorrect AC Size for Your Room
One of the most common issues is installing the wrong size unit for your space. If your AC is too small, it will struggle to cool your room, leading to poor performance and overworking. If it’s too large, it may cool the room quickly but won’t remove humidity, leaving the air feeling sticky and uncomfortable.
Tip: Always consult a professional before buying to calculate the right BTU capacity for your space.
2. Poor AC Installation
Even the most high-end AC unit can become inefficient if it’s installed improperly. Faulty ductwork, improper placement of the indoor and outdoor units, or incorrect refrigerant levels can prevent your AC from working as intended.
Residents across Dubai, Sharjah, and Ajman should only trust licensed professionals like the Best AC Repair in Dubai for proper installation.
3. Thermostat Issues
Your thermostat might be the real culprit. If it’s not calibrated correctly or placed in the wrong location (like near a heat source or window), your AC won’t receive accurate temperature readings, causing it to either undercool or overcool the space.
Fix: Make sure your thermostat is functional and ideally positioned.
4. Blocked Air Filters
A clogged air filter reduces airflow and forces your AC to work harder. This can prevent it from cooling effectively. If your new AC was installed with an already dirty filter or hasn’t been cleaned post-installation, cooling problems are inevitable.
Make a habit of checking your air filter every month—especially during peak summer.
5. Refrigerant Leaks or Low Levels
Refrigerant is the lifeblood of your air conditioner. If there’s a leak or insufficient refrigerant level due to poor installation or manufacturing defects, your AC won’t cool properly.
Don’t try to fix this yourself—contact the Best AC Repair in Dubai at +971 050-3338786 to inspect and recharge your refrigerant safely.
6. Dirty Condenser Coils
Even if the AC unit is new, the condenser coils (located outside) can quickly accumulate dust, dirt, and debris in areas like Dubai, Sharjah, and Ajman. When these coils are dirty, they can’t release heat efficiently, affecting the unit’s ability to cool your home.
Schedule a coil cleaning service every 3–6 months to avoid performance dips.
7. Electrical or Sensor Problems
If your new AC unit is showing erratic behavior—like switching on and off frequently—it could be an electrical problem or faulty sensor. These are often the result of installation errors or internal manufacturing issues.
It’s best to let a professional technician from the Best AC Repair in Dubai examine your system.
8. Poor Insulation or Room Sealing
Sometimes, the problem isn’t with the AC—it’s your home. If the room isn’t properly insulated or has gaps around windows and doors, cool air will escape, and warm air will enter. This makes your AC run longer to maintain the desired temperature.
Consider sealing leaks and improving insulation for better efficiency.
9. AC Set to the Wrong Mode
Surprisingly, many people forget to switch the AC from ‘Fan’ or ‘Dry’ mode to ‘Cool’ mode after installation. Double-check your settings to make sure your AC is actually trying to cool the air.
Also, set the temperature to at least 24°C for optimal performance and energy savings.
10. Manufacturer Defects
Yes, it’s rare—but not impossible. Sometimes a brand-new unit could have a manufacturing defect that affects its cooling ability. If you’ve tried everything else, consider contacting the manufacturer for a warranty claim.
Meanwhile, expert diagnostics from the Best AC Repair in Dubai can help you determine whether a replacement or repair is needed.
