Do you sometimes notice that the air curtain is running, yet hot air and dust still enter as if nothing has changed? In Saudi Arabia, extreme summer heat, dust, and frequent door openings in retail stores and commercial entrances mean that even a small issue can quickly turn into cooling losses, customer discomfort, and higher energy bills.
The problem is not always a weak unit. In many cases, it comes down to improper installation, incorrect settings, or neglected maintenance. Even worse, some faults start with a small sign—such as an unusual noise or odor—and gradually develop into a complete shutdown.
If you want to understand the most common air curtain problems in Saudi Arabia and how to solve them in a practical, no-guesswork way, keep reading—you will notice a clear difference in performance.
What Are the Most Common Air Curtain Problems in Saudi Arabia?
Air curtain problems often appear due to the Saudi climate and the heavy use of commercial entrances. High temperatures, constant dust, and long operating hours mean that without correct adjustment or regular maintenance, the air curtain can shift from being an effective solution to an operational burden that affects HVAC efficiency and customer experience.
Below are the most common issues faced by air curtain users in Saudi Arabia, with an explanation of each problem and its impact:
Weak or Interrupted Airflow
This issue is usually caused by dust buildup on filters, reduced performance of the internal fan, or incorrect airflow power settings. Weak airflow leads to the loss of the air barrier, allowing hot air to enter and reducing indoor cooling efficiency.
Loud or Unusual Operating Noise
Some noise during operation is normal, but an increase or change in sound often points to a mechanical issue. Identifying abnormal noise early helps prevent the problem from escalating into a major fault.
Outside Air Leakage Despite the Air Curtain Operating
This problem is commonly linked to incorrect vane angles or selecting an air curtain with insufficient power for the entrance width and height. The issue is more noticeable in large commercial entrances that require precise air distribution.
The Air Curtain Does Not Operate at All
The cause is usually electrical, such as circuit breakers, wiring issues, or a control board fault. Random interference with the unit is not recommended, as some faults carry safety risks and require professional inspection.
Unpleasant Odors from the Air Curtain
Odors typically result from dust accumulation combined with moisture, which is common in the Saudi environment. This issue directly affects customer experience and leaves a negative impression of the space.
Vibration or Unit Instability
Vibration is often caused by installation errors or unbalanced mounting. Over time, vibration accelerates component wear and reduces the overall lifespan of the air curtain.

Practical Solutions for Air Curtain Problems (When to Self-Fix and When to Call a Specialist)
Solutions for air curtain problems usually start with simple steps that quickly reveal the cause, especially when related to dust, settings, or poor maintenance. Some cases, however, require an air curtain specialist when electrical or mechanical fault indicators appear and affect safety and cooling efficiency.
Solutions You Can Perform Yourself as Initial Steps
Basic air curtain maintenance, such as regularly cleaning filters, checking correct settings, and adjusting fan speed, helps restore airflow and reduce dust infiltration. If the issue persists, performing a system reset can resolve temporary operational errors without dismantling the unit.
Solutions That Require a Specialized Air Curtain Technician
Professional intervention becomes necessary when there is suspected damage to the internal fan or when adjusting the air discharge angle to match entrance type and height for effective air sealing. Repeated vibrations or electrical faults should also be handled by a technician to avoid premature damage or risks related to wiring and the control board.

Common Mistakes That Make Air Curtain Problems Worse
Most air curtain issues in Saudi Arabia start with a hidden cause: a small mistake in selection, operation, or installation that allows the unit to run without creating a true air barrier. With heat, dust, and frequent door openings, these mistakes turn into recurring faults, weaker cooling, and higher energy consumption. Common mistakes that worsen air curtain problems include:
Selecting an air curtain that does not match the entrance height or width, leading to external air leakage even during operation.
Operating the air curtain at unsuitable power or speed, which weakens airflow or increases noise and disrupts performance.
Neglecting regular maintenance and filter cleaning, resulting in dust buildup, odors, and reduced HVAC efficiency.
Relying on non-specialized installation without proper adjustment of air angle and mounting height, increasing vibration and shortening the unit’s lifespan.

Frequently Asked Questions About Air Curtain Problems
1. How do you reset an air curtain?
Resetting is usually done by switching the unit off from the circuit breaker for 1–3 minutes, then turning it back on, or by using the Reset button if available on the control unit. If the problem returns after resetting, it is best to have the settings and control board checked by a specialist.
2. What is the expected lifespan of an air curtain?
The typical lifespan ranges from 7 to 12 years and may vary depending on unit quality, operating intensity, installation quality, and adherence to regular maintenance in the Saudi environment (dust and heat).
3. Why does the air curtain not work even though power is available?
Possible causes include a tripped internal breaker, control board fault, blown fuse, or an issue with the switch or remote control. Having power does not necessarily mean it is reaching the control unit correctly, so electrical inspection by a technician is recommended.
4. Can air curtains operate continuously?
Yes, they can run for long periods if designed for commercial use and set correctly, with regular cleaning in place. Continuous operation with dirty filters or incorrect power settings accelerates faults and increases energy consumption.
5. When is maintenance better than replacement?
Maintenance is the better option when the issue is limited—such as cleaning, air angle adjustment, or replacing an internal component at a reasonable cost—and the unit is still within its normal lifespan. Replacement is preferable when faults are frequent and costly, performance remains weak despite maintenance, or the unit has exceeded its expected lifespan and become inefficient.
