Professional HVAC Repair & Maintenance Service in Dhaka
Reliable AC Service Ltd. provides certified HVAC repair, installation, and maintenance across Dhaka city. Whether your central air system, duct unit, or VRF system needs urgent fixing or a scheduled tune-up — our trained technicians respond fast and fix it right.
Understanding HVAC Systems — Heating, Ventilation & Air Conditioning
HVAC stands for Heating, Ventilation, and Air Conditioning — the complete system that controls your building’s indoor temperature, air quality, and humidity. In Dhaka’s hot and humid climate, a properly functioning HVAC system is not a luxury; it is a necessity for homes, offices, hospitals, shopping malls, and industrial spaces.
Unlike a standard split AC, a full HVAC setup manages entire buildings through centralized ducts, air handlers, and sometimes VRF (Variable Refrigerant Flow) systems. When any part of this network fails, it impacts every room — which is why you need a specialist, not just a general AC repairman.
- Central AC & Air Handlers — cools large floor areas evenly through ductwork
- Ventilation & Duct Systems — keeps air fresh and prevents toxic build-up
- VRF / VRV Systems — energy-efficient, multi-zone commercial cooling
- Chiller & Cooling Tower Units — used in large commercial and industrial buildings
- Thermostat & BMS Controls — automated climate control for smart buildings

Call for Emergency8 Signs Your HVAC System Needs Repair Right Now
Catching a problem early saves you from a full system breakdown. If you notice any of these signs in your Dhaka home or office, call Reliable AC Service Ltd. before the damage gets worse.
Weak or Warm Airflow
If your HVAC blows air but the room stays warm, the compressor may be failing or refrigerant is low. Do not delay — this often signals a bigger system issue.
Unusual Noises — Grinding, Squealing, Banging
Strange sounds from your unit often mean loose components, a failing motor bearing, or debris stuck in the fan. Ignoring this leads to expensive part replacements.
Sudden Spike in Electricity Bills
When an HVAC system is struggling — dirty coils, blocked filters, or low refrigerant — it runs longer to maintain temperature, pulling extra power and inflating your BPDB bill.
Frequent On/Off Cycling (Short Cycling)
If your unit turns on and off every few minutes instead of running in steady cycles, there is likely an issue with the thermostat, refrigerant charge, or the compressor itself.
Water Leaking Around the Unit
A small amount of condensation is normal, but active water pooling around your indoor unit signals a clogged drain pipe, a frozen coil, or a refrigerant leak — all needing immediate attention.
Bad Smell from Vents
Musty smells indicate mold growth inside your ducts or drain pan. A burning smell could mean electrical faults or overheating components — a serious fire risk that needs same-day inspection.
Uneven Cooling Across Rooms
If one room is cool and another feels like an oven, your duct system may have leaks, blockages, or an undersized air handler. Our technicians will balance the airflow correctly.
System Over 5 Years Without Servicing
In Dhaka’s dusty and humid climate, HVAC systems need servicing every 6–12 months. A system that has not been maintained in years is likely operating at 30–40% less efficiency.

What Dhaka Customers Say About Our HVAC Service
Hear from real customers across Dhaka who trusted Reliable AC Service Ltd. with their HVAC systems.
Our office HVAC completely broke down in the middle of summer. Reliable AC Service Ltd. sent a technician within two hours. He found a faulty compressor, explained everything clearly, gave me the price before touching anything — and had it running by evening. Really professional work.
I booked an annual maintenance contract for 4 AC units in my apartment. The team arrived on time, cleaned everything thoroughly, topped up the gas, and checked all electrical connections. My electricity bill actually went down after the service. Highly recommended for HVAC maintenance in Dhaka.
We run a small garments factory in Mirpur. Our duct AC system stopped cooling properly. Reliable AC Service Ltd. did a full duct cleaning and gas refill. The difference was dramatic — temperature dropped to normal within the first day. Fair pricing, honest team. Will use them again.

HVAC Repair Dhaka — Frequently Asked Questions
Got questions about HVAC repair or maintenance? Here are the answers to what Dhaka customers ask us most.
A standard AC service covers a single split or window unit — cleaning filters, checking gas, and basic maintenance. HVAC repair is broader and involves central air conditioning systems, ducted networks, VRF/VRV multi-zone setups, and air handling units. HVAC work requires advanced training because the systems are larger, more complex, and serve entire buildings rather than a single room. Reliable AC Service Ltd. handles both regular AC servicing and full commercial HVAC system repairs across Dhaka.
HVAC repair costs in Dhaka typically range from ৳1,500 for minor fixes to ৳25,000+ for compressor replacement or major component repairs. Diagnosis alone costs ৳500–৳1,000 and is adjusted if you proceed with the repair. Gas refills cost ৳1,200–৳3,500 per unit depending on the type of refrigerant. We always provide a written quote before starting any work — no hidden charges, no surprise bills. Call 01824-283141 for a free assessment.
Yes. Reliable AC Service Ltd. operates every day of the year from 8AM to 12 midnight across Dhaka city. If your HVAC system breaks down urgently, call 01824-283141 and we will dispatch a technician as quickly as possible. We do not charge extra for evening calls — our service fee is the same regardless of time.
In Dhaka’s hot, humid, and dusty climate, HVAC systems should be serviced at least every 6 months — ideally before summer (March–April) and again mid-year. Commercial systems running continuously may need quarterly servicing. Skipping maintenance leads to reduced cooling efficiency, higher power bills, and sudden breakdowns at the worst possible times. Our Annual Maintenance Contract (AMC) covers all of this for you with scheduled visits.
Our technicians are trained to repair all major HVAC brands available in Bangladesh, including Gree, Midea, Samsung, General, Carrier, Daikin, LG, Panasonic, Haier, Hisense, Toshiba, Chigo, York, and Trane. Whether it is a residential split system or a commercial ducted HVAC setup — we can handle it.
Yes. Reliable AC Service Ltd. offers Annual Maintenance Contracts (AMC) for offices, garment factories, hospitals, hotels, shopping centres, and other commercial properties in Dhaka. The AMC includes scheduled servicing visits, priority emergency response, cleaning, gas top-up checks, and full system inspections. It is the most cost-effective way to protect your HVAC investment. Contact us at 01824-283141 to discuss an AMC tailored to your property.
This is one of the most common HVAC complaints we receive in Dhaka. The usual causes are low refrigerant (gas leak), a dirty or frozen evaporator coil, a failing compressor, blocked air filters, or duct leaks losing cooled air before it reaches the room. Sometimes a faulty thermostat is misreading the temperature. Our technicians will inspect every component and identify the exact cause. Do not delay — running a system with low gas damages the compressor over time.
Yes. Reliable AC Service Ltd. handles new HVAC system installations for residential apartments, commercial offices, hospitals, and industrial spaces in Dhaka. We assess the space, recommend the right system capacity and type, supply the equipment, and complete the full installation and commissioning.
