What Is an HVAC System and Why It Matters in Dhaka
HVAC stands for Heating, Ventilation, and Air Conditioning. In Dhaka’s tropical climate, the heating part rarely gets used — but ventilation and cooling are non-negotiable for both homes and businesses. Your HVAC system pulls in fresh air, removes humidity, and distributes conditioned air through a network of ducts to every room in the building.
Most buildings in Dhaka that run HVAC systems use one of these setups: central air conditioning with sheet metal ductwork, ducted split AC units hidden above false ceilings, VRF or VRV systems popular in offices and shopping malls along Gulshan and Motijheel, or packaged units mounted on rooftops of commercial buildings.
When any component in this chain fails — compressor, blower motor, thermostat, duct seal, or refrigerant line — the entire building feels it immediately. That is exactly why R. K. Refrigeration Works Ltd. built a dedicated HVAC repair team that understands these systems from the ground up, not just surface-level AC repair in Dhaka.
Signs Your HVAC System Needs Immediate Repair
Most HVAC breakdowns do not happen overnight. They give warning signs for weeks before the system finally gives out. Catching these early can save you from a full compressor replacement that costs lakhs of taka.
1Uneven Cooling Across Rooms
Some rooms feel like a freezer while others stay warm. This usually points to duct leaks, blocked vents, or a failing zone control board.
2Strange Noises From Unit or Ducts
Banging, grinding, or whistling sounds mean something is loose, worn out, or obstructed inside the system. Ignoring this damages neighboring parts fast.
3Sudden Spike in Electricity Bills
If your monthly bill jumped 30-40% without adding new appliances, your HVAC is likely working harder than it should due to a failing component.
4Weak Airflow From Vents
When air barely comes out of the duct openings, the blower motor might be failing or the evaporator coil could be choked with dirt and ice buildup.
5Foul Smell Through Ductwork
Musty or burning smells mean mold growth inside ducts or electrical components overheating. Both situations need urgent attention for health and safety.
6Thermostat Not Responding
You set the temperature but the system does not follow. The thermostat itself might be faulty, or the wiring between it and the main board could be damaged.
7Water Leakage Around Indoor Unit
A clogged drain line or cracked condensate pan causes water to drip from the indoor unit. Left unchecked, this damages your false ceiling and walls.
8System Short Cycling Frequently
If your HVAC turns on and off every few minutes, it could be a refrigerant leak, bad thermostat, or overheating compressor — all of which worsen with each cycle.

Commercial vs Residential HVAC Repair
The approach, tools, and timeline for fixing a home ducted AC system are very different from servicing a 50-ton VRF setup in a Banani office tower. Here is a clear comparison so you know what to expect.
| Feature | Residential HVAC | Commercial HVAC |
|---|---|---|
| System Type | Ducted split, central AC | VRF/VRV, package units, chillers |
| Typical Capacity | 1.5 to 5 tons | 5 to 100+ tons |
| Ductwork | Simple single-zone layout | Complex multi-zone with dampers |
| Technician Required | 1 trained technician | 2-3 engineers with specialization |
| Response Time | Same day service | Within 24 hours |
| Spare Parts | Usually available locally | May need to order from supplier |
| Diagnostic Fee | 500 – 800 BDT | 1,500 – 3,000 BDT |
| Repair Starting Price | 1,500 BDT | 5,000 BDT |
Prices are estimated and depend on the specific problem, brand, and parts needed. We always provide a written quotation before starting any work.

Frequently Asked Questions About HVAC Repair
These are the questions our customers ask most often. If your question is not here, visit our full FAQ page or call us directly.
Simple repairs like thermostat replacement or gas refill take 1 to 2 hours. Compressor repairs usually need 3 to 5 hours. Full VRF system troubleshooting in a commercial building can take a full day. We always give you a time estimate before starting work so you can plan accordingly.
Yes, commercial HVAC repair is a significant part of our work. We service VRF and VRV systems in offices, shopping malls, hospitals, restaurants, and factories across Dhaka. Our engineers are trained to handle multi-zone systems from brands like Daikin, Mitsubishi, and LG that are standard in commercial setups.
Regular AC repair typically deals with wall-mounted or floor-standing split AC units that cool a single room. HVAC repair involves systems that cool entire buildings through ductwork — central AC, ducted splits, VRF/VRV, and packaged units. The components are larger, the duct network adds complexity, and troubleshooting requires understanding of airflow dynamics, zone control, and building load calculations. We handle both, but HVAC work demands specialized training and tools.
In Dhaka’s climate where HVAC systems run heavily for 8 to 10 months a year, we recommend professional servicing at least twice a year — once before summer starts in March and once before the monsoon season in May. Commercial systems that run almost year-round should get quarterly checkups. Regular cleaning and maintenance extends system life by 30-40% and keeps electricity bills in check.
We operate from 8AM to 12AM every single day, including weekends and public holidays. If your HVAC system fails during a corporate event, a restaurant’s busy dinner shift, or any critical situation, call us at 01859977692 and we will prioritize your job. For commercial clients with annual maintenance contracts, we offer the fastest response times.
It depends on the system’s age, the cost of repair, and its current efficiency. As a general rule: if the system is over 10-12 years old and the repair cost exceeds 40% of a new system, replacement makes more financial sense. If the system is under 8 years old and the issue is a single component failure like a compressor or fan motor, repair is usually the smarter choice. Our technicians will give you an honest assessment — we do not push replacements just to make a bigger sale.
We repair all major HVAC brands available in Bangladesh including Daikin, Mitsubishi Electric, LG, Samsung, Carrier, General (Hitachi), Toshiba, York, and Gree. Our workshop stocks commonly needed parts for these brands, which means faster repairs for you. For less common brands, we can source parts within 1-2 business days.
Yes, every HVAC repair carried out by R. K. Refrigeration Works Ltd. comes with a 30-day warranty. This covers the specific component we repaired or replaced. If the same issue recurs within 30 days due to our workmanship or the part we used, we will fix it again at no additional charge. For compressor replacements, we also pass through the manufacturer’s warranty which is typically 1 to 5 years depending on the brand.
