It is the peak of summer in Muscat, and your AC unit is running, but the air coming out is warm. This is a frustrating and all-too-common scenario in the Sultanate.

At Rubo Al Hail International Enterprise, we understand that in our climate, a working AC is essential for survival, not just comfort. If your system is blowing warm air—or no cool air at all—the problem often lies with a specific component that needs replacing. Here is a guide to the most common culprits and the parts you need to fix them.

1. Low or Leaking Refrigerant (Gas)

Your AC relies on refrigerant (gas) to absorb heat. If the levels are low due to a leak or poor maintenance, the unit cannot cool the air.

• The Fix: You likely need to locate the leak and top up the gas.
• Our Stock: We supply premium quality Refrigerant Gases (R22, R410A, R134a) to ensure your system reaches the correct pressure and cooling capacity immediately.

2. Faulty Capacitor or Compressor

Often, the indoor fan runs, but the outdoor compressor does not kick in. This is frequently caused by a weak or dead capacitor.

• The Fix: Replacing a capacitor is a quick and affordable fix that often restores cooling instantly.
• Our Stock: As a leading HVAC wholesale dealer in Oman, we carry a massive inventory of capacitors for all major brands, as well as high-performance compressors (Rotary, Scroll, and Reciprocating) for when major repairs are needed.

3. Dirty or Clogged Air Filters

The dust in Oman is relentless. A blocked filter restricts airflow, which can cause your evaporator coil to freeze up or the compressor to overheat and shut down.

• The Fix: Check your filters monthly. If they are gray or clogged, wash or replace them.
• Our Stock: We offer a variety of filter media and cleaning chemicals to keep your airflow unobstructed.

4. Dirty Condenser Coils

The outdoor unit (condenser) releases the heat. If the coils are covered in dust and sand, the heat cannot escape, and the cooling cycle fails.

• The Fix: The coils need to be chemically cleaned to restore heat transfer.
• Our Stock: We sell specialized Coil Cleaners (Acid and Non-Acid based) that cut through grime and salt deposits, restoring efficiency in minutes.

5. Thermostat Issues

Sometimes the machinery is fine, but the “brain” is confused. A faulty thermostat might not be sending the signal to the compressor to turn on.

• The Fix: Recalibrate or replace the thermostat.
• Our Stock: We stock a range of digital and manual thermostats compatible with most window, split, and central units found in Oman.
