Corrosion on electrical connections creates dangerous conditions. Dubai’s humidity accelerates this corrosion process.
Control panel errors or unresponsive controls suggest electrical system problems that need expert diagnosis and repair.
Refrigerant and Water Leaks
Puddles of water around the unit indicate drainage problems or coil issues. These leaks can damage building structures and create mold conditions.
Ice formation on coils during operation suggests refrigerant problems or airflow restrictions. This condition reduces efficiency and can damage equipment.
Refrigerant leaks are both expensive and environmentally harmful. They also prevent proper cooling and dehumidification.
Condensate backup can flood mechanical rooms and damage other building systems. Proper drainage is essential for safe operation.
Performance Issues That Signal Maintenance Needs
Inadequate Cooling and Dehumidification
When your FAHU can’t maintain desired temperatures despite running constantly, major components may be failing. This problem is especially noticeable during Dubai’s hottest months.
Rooms that used to stay comfortable now feel warm or humid. This change indicates declining system capacity or efficiency.
The system takes longer to reach target conditions after startup. Delayed response suggests worn components or control problems.
Some areas of your building stay uncomfortable while others feel fine. This inconsistency points to distribution or capacity issues.
Filter and Airflow Problems
Filters that get dirty much faster than usual suggest system problems or increased contamination sources. This change requires investigation.
Reduced airflow from vents indicates blockages or fan problems. Poor airflow affects both comfort and air quality.
Dust accumulation near vents or on building surfaces means filtration isn’t working properly. This issue affects occupant health.
Pressure imbalances between different building areas suggest airflow distribution problems that need professional attention.
