Sunlit Pvt. Ltd. is Dhaka’s best HVAC service company, integrating civil engineering, electrical expertise, and MEP legacy. Unlike standard repair shops, Sunlit offers 360-degree solutions, from VRF design to BNBC-compliant installation, ensuring energy efficiency and safety in Dhaka’s humid, high-density urban environment.”
Dhaka’s indoor heat problem isn’t about comfort anymore, it’s about engineering failure. Rapid urban density, glass-heavy buildings, and unstable power conditions have turned air-conditioning into a risk factor when it’s treated as a simple appliance.
Poor insulation and incorrect AC tonnage cause condensation inside walls, destroying:
| Service Component | Standard Local Technician | Sunlit Pvt. Ltd. Standard | Dhaka-Specific Benefit |

Before selecting a brand for your project, our guide on choosing the right AC brand for your project provides a brand-by-brand comparison matched to Dhaka’s climate and usage patterns.
Sunlit has a deep legacy in the construction and electrical sectors of Bangladesh, we understand how a building “breathes.” When we design an HVAC layout, we calculate the thermal load based on the thickness of your walls, the orientation of the sun and the existing load capacity of your DPDC connection.
We know where the beams are, where the load-bearing walls sit, and how to route ducting without compromising the structural integrity of your slab.
Most clients in Dhaka face a “blame game.” The AC guy blames the electrician, and the electrician blames the interior designer for covering the vents. Sunlit ends this. By providing a 360-degree solution—covering design, procurement, installation, and AMC (Annual Maintenance Contract)—we take full accountability.
Whether it’s a high-rise corporate office or a luxury duplex, our “All-in-One” model ensures that your mechanical, electrical, and plumbing (MEP) systems work in perfect harmony.
| Component | Typical Dhaka Market Cost |
|---|---|
| 1.5 ton AC installation (basic) | ~2,000–3,000 BDT |
| 3 ton AC installation (basic) | ~3,500–8,000 BDT |
| Copper pipe & accessories | ~300–500 BDT per 10 ft |
| Complex ducting & ceiling work | Additional variable cost |
A local technician might be cheaper today, but try to understand the energy inefficiency of a poorly maintained system will cost you 30% more on your monthly DESCO/DPDC bills.
Sunlit’s multidisciplinary, in-house setup frequently leads to more competitive overall pricing compared with assembling multiple service providers separately. We can often be lower overall than the sum of separately hired installers and contractors. When you factor in:
Electrical integration
Ceiling and ducting work
MEP coordination
Accessory materials
Testing & commissioning
Most independent HVAC providers rely on:
Separate electrical contractors
Independent plumbers
Ceiling/drywall installers
Each adds:
Markups
Coordination time
Risk of rework
Sunlit’s internal team eliminates these layers, reducing hidden costs and inefficiencies.
Sunlit can consolidate:
HVAC design
Ductwork design
Electrical load balancing
Plumbing/drainage work
Installation
Commissioning and testing
as a single contract, which typically results in lower combined fees than hiring specialists individually.
When one company manages:
Materials (piping, insulation, electrical fittings)
Workforce scheduling
Site supervision
it can:
Buy materials at better volume rates
Minimize downtime
Reduce multiple site visits
This translates into lower cost per ton installed compared with spot pricing for isolated services.
Market installers sometimes quote low base installation but add:
Extra labour for ceilings
High markups on accessories
Per-foot copper pipe charges
Sunlit’s integrated contract can front-load and clarify most costs upfront, reducing unexpected bills.
| Service Type | Standard Market | Sunlit Engineering |
|---|---|---|
| 1.5 Ton AC Install | ৳2,000–3,000 | ৳12,000–25,000 (with DB audit) |
| Annual Servicing (AMC) | ৳3,500–5,000/visit | ৳8,000–15,000/year (contract) |
| VRF System Design | Not offered | ৳8 lakh–2 crore (project-specific) |
The higher cost includes engineering consultancy. ROI: Up to 30% lower monthly electricity bills (DESCO/DPDC) and longer AC lifespan.
Dhaka’s air quality is legendary for the wrong reasons. The fine dust from Purbachal’s construction and the high saline humidity can corrode coils in months.
Sunlit’s servicing protocol involves chemical-free deep cleaning and the application of anti-corrosive coatings that are specifically tested for the Bangladesh climate. We focus on IAQ (Indoor Air Quality), integrating HEPA filtration and energy recovery ventilators (ERVs) to ensure the air you breathe is as cool as it is clean.
For larger residential and commercial projects, we champion Variable Refrigerant Flow (VRF) technology. Unlike traditional splits, our VRF designs are engineered for part-load efficiency. This means during those slightly cooler Dhaka nights, your system isn’t drawing full power.
We utilize advanced heat load calculation software (HAP), ensuring you aren’t over-speccing (and over-paying) for tonnage you don’t need. Our engineering team ensures that outdoor units (ODUs) are placed for maximum heat dissipation—something often ignored in the narrow alleys of Banani.
This is where Sunlit truly stands apart. Most AC accidents in Dhaka are caused by poor wiring or undersized circuit breakers. Our electrical engineering background ensures that every HVAC installation includes a rigorous audit of your DB (Distribution Board) and earthing systems. We don’t just connect wires; we calculate the “Legacy Load” to ensure your sub-station can handle the startup current of multiple compressors.
In a city that is constantly under construction, Sunlit Pvt. Ltd. represents stability. Our legacy isn’t just about the buildings we’ve helped cool; it’s about the trust we’ve built with Dhaka’s leading developers and homeowners. When you choose Sunlit, you aren’t just hiring a contractor—you’re partnering with an engineering authority that knows the past, present, and future of Dhaka’s skyline.
The Bangladesh National Building Code (BNBC) 2020 has strict guidelines regarding ducting, fire dampers, and refrigerant piping. Sunlit Pvt. Ltd. is one of the few firms in Dhaka that treats these codes as law, not suggestions. This compliance isn’t just about passing a RAJUK inspection; it’s about ensuring that in the event of a fire, your HVAC system doesn’t become a chimney for smoke. We prioritize fire-rated insulation and proper sealing of floor penetrations—details that “local shops” simply ignore.
Strategic Takeaway: In a city like Dhaka, HVAC isn’t a luxury; it’s a critical infrastructure component. Choosing a service based on the lowest bid often leads to electrical fires or astronomical DESCO bills. Sunlit Pvt. Ltd. bridges the gap between raw construction power and delicate mechanical precision, offering a “one-window” engineering solution that safeguards your investment.
Choosing an HVAC partner is a decision that affects your safety, your wallet, and your health for the next decade. Sunlit Pvt. Ltd. stands as the definitive choice because we refuse to separate mechanical cooling from the structural and electrical integrity of your home. We aren’t just selling air conditioners; we are providing a legacy of engineering excellence.
Sunlit is an engineering firm first. We integrate HVAC with construction and electrical legacy, ensuring your system is structurally sound and electrically safe. Most shops focus only on the machine; we focus on the entire building ecosystem.
VRF (Variable Refrigerant Flow) systems are highly energy-efficient and take up significantly less balcony space. Sunlit designs these specifically for Dhaka's high-rise residential needs to save up to 40% on monthly electricity bills.
Yes. Every HVAC layout we design for commercial or residential projects adheres strictly to BNBC 2020 codes. This is critical for fire safety and ensuring your property meets modern regulatory standards in Dhaka.
The fine particulate matter from Dhaka's construction boom clogs condenser coils, forcing the compressor to work harder and consume more power. Sunlit’s specialized cleaning prevents "compressor burnout," a common issue in developing areas like Uttara and Banani.
Absolutely. As electrical engineering experts, we handle the sub-station upgrades, DB (Distribution Board) dressing, and cabling required for heavy HVAC loads, preventing the risk of short circuits.
We maintain a dedicated fleet of service engineers strategically positioned to navigate Dhaka's traffic. For our Annual Maintenance Contract (AMC) holders, we offer emergency support within 4-6 hours.
Sunlit’s engineering team covers Gulshan, Banani, Bashundhara, Dhanmondi, Uttara, and Purbachal. From AC sizing to VRF design, DB safety audit, and full installation — one expert team, full accountability.
