Expert HVAC Repair Service in Dhaka – Central AC, Chiller & VRF Specialists
When a central air conditioning system breaks down, it affects your entire building. Hoque Refrigeration And Engineering Works Ltd. provides fast, commercial-grade HVAC repair in Dhaka for offices, hospitals, restaurants, and large residences.
Commercial & Residential HVAC Systems We Repair
HVAC covers far more than a standard split AC. We service the complex cooling and ventilation systems that keep large buildings running comfortably across Dhaka.
Central Air Conditioning
Complete diagnostics and repair for ducted central AC systems, including AHU (Air Handling Units), FCU (Fan Coil Units), and chilled water pipelines.
Chiller Systems
Repair and maintenance for air-cooled and water-cooled chillers. We handle compressor replacement, refrigerant charging, and control panel troubleshooting.
VRF / VRV Systems
Specialized repair for Variable Refrigerant Flow multi-split systems. We fix communication errors, inverter board failures, and refrigerant leakage across Daikin, Mitsubishi, and Toshiba VRF units.
Ducted Split Systems
Repair for concealed ducted units providing whole-home or whole-office cooling. We fix airflow issues, thermostat faults, and frozen evaporator coils.
Package Units
Roof-top and ground-mounted package AC units used in commercial spaces. We repair compressors, fans, and control boards for all major brands.
Ventilation & Exhaust Systems
Repair and cleaning of fresh air systems, exhaust fans, and kitchen ventilation hoods for restaurants and commercial kitchens across Dhaka.
Common HVAC Problems We Fix in Dhaka
Large cooling systems show specific warning signs before a total breakdown. If you notice any of these issues, call for professional HVAC repair service immediately.
Uneven Cooling Across Zones
Some rooms are freezing while others stay warm. This usually indicates a faulty zone damper, an imbalanced duct system, or a failing FCU that needs professional recalibration.
System Running Non-Stop
If the compressor never cycles off, the thermostat may be malfunctioning, the refrigerant may be low, or the building insulation is compromised. We diagnose the root cause quickly.
Strange Noises from AHU or Ducts
Banging, screeching, or rattling sounds from the air handling unit or ductwork mean loose fan belts, failing bearings, or debris inside the blower wheel. Ignoring it leads to costly compressor failure.
High Electricity Bills
An unexplained spike in energy usage often points to an inefficient HVAC system working harder than it should due to dirty coils, low refrigerant, or aging components. We restore peak efficiency.
Poor or Weak Airflow from Vents
Weak airflow makes the building feel stuffy. Causes range from clogged air ducts and dirty filters to a failing blower motor. We trace the restriction and fix it.
Refrigerant or Water Leaks
Puddles near the indoor unit or ice on the refrigerant lines signal a leak. Left unfixed, it damages the compressor. We locate the leak, seal it, and recharge the system.
Our HVAC Repair and Maintenance Process
Commercial HVAC systems require a systematic approach. Our four-step process ensures accurate diagnostics and long-lasting repairs.
Site Assessment
Our engineer visits your property, inspects the HVAC layout, checks the chiller/AHU status, and reviews error codes on the controller.
Diagnostics & Report
We identify the fault using professional tools and provide a detailed report with the exact problem, required parts, and a transparent cost estimate.
Professional Repair
Our technicians carry out the repair — whether it is a compressor swap, board repair, gas top-up, or ductwork sealing. We minimize downtime.
Testing & AMC Setup
We test the full system under load to verify the fix. We also offer Annual Maintenance Contracts (AMC) to prevent future breakdowns.
