In the UAE’s intense climate, HVAC systems are not just an amenity—they’re mission-critical. Yet, many commercial buildings suffer from avoidable issues that compromise comfort, safety, and efficiency. At Zahrat Alhibaa Technical Services LLC (ZATS), we’ve seen how these mistakes can quietly drain budgets and shorten equipment lifespan.
Here are the top five HVAC mistakes made in commercial facilities—and what you can do to steer clear of them.
1. ❌ Poor System Design & Sizing
The Mistake:
Installing an HVAC system that’s too large or too small for the space.
The Impact:
Oversized units cycle on and off frequently, wasting energy. Undersized systems run constantly, driving up costs and failing to meet cooling demands.
How to Avoid It:
Hire experienced HVAC professionals (like ZATS) who perform accurate load calculations and design systems that fit your space, occupancy, and usage.
2. 🛠️ Skipping Regular Maintenance
The Mistake:
Waiting until the AC breaks before calling a technician.
The Impact:
Reduced system efficiency, unexpected breakdowns, and costly emergency repairs.
How to Avoid It:
Schedule preventive maintenance. Our AMC packages at ZATS include regular inspections, cleaning, and performance checks to keep your HVAC running efficiently year-round.
3. 🌬️ Ignoring Airflow Imbalances
The Mistake:
Not balancing air distribution between zones or floors.
The Impact:
Uneven temperatures, cold/hot spots, and energy waste.
How to Avoid It:
Perform airflow assessments and duct balancing. ZATS offers duct optimization and zone control solutions to ensure comfort and energy efficiency throughout your building.
4. 🧼 Dirty Filters and Coils
The Mistake:
Failing to replace air filters and clean condenser/evaporator coils.
The Impact:
Reduced airflow, poor indoor air quality, and overheating of components.
How to Avoid It:
Replace filters monthly and clean coils during regular service visits. We include these steps in all ZATS HVAC maintenance plans.
5. ⚡ Neglecting Automation & Controls
The Mistake:
Relying on outdated thermostats or ignoring building automation.
The Impact:
Wasted energy, poor control over zones, and missed savings.
How to Avoid It:
Upgrade to smart controls or integrate HVAC into your Building Management System (BMS). ZATS can recommend and install systems that improve control, tracking, and performance.
