Bangladesh's Most Trusted HVAC Partner — Since 2005
For over 20 years, Cooltech Corporation has been designing, supplying, installing, and maintaining certified HVAC systems across Bangladesh — from factory floors in Gazipur to hospital theatres in Dhaka, from luxury towers in Gulshan to garment units in Chattogram.
Built on engineering excellence
Cooltech Corporation is a leading air conditioning company in Bangladesh since 2005. From the very beginning, we started our journey with the Residential Type Air Conditioner. Within a couple of years, we expanded our business and began to serve light commercial to Industrial Air Conditioning solutions to our valuable customers.
Cooltech has covered all aspects of work in the area of mechanical installations including HVAC systems. During this time Cooltech has become a specialist in planned preventative installation, testing, commissioning, and maintenance.
Our success is based on the continuous commitment our team gives to all our clients — continually updating and developing our cost-competitive pricing structure, and ensuring every client receives the best solution for their specific building and budget.
Today, our certified engineers operate across all 64 districts of Bangladesh, delivering projects that comply with the world's most demanding standards — AHRI, ETL, and ASHRAE 90.1.

Internationally certified. Locally trusted.
Every system Cooltech Corporation supplies and installs meets international performance, safety, and energy standards. These certifications are not optional extras — they are fundamental to how we select and recommend equipment.
AHRI Certified
Air-Conditioning, Heating & Refrigeration Institute
All chillers and AC units supplied by Cooltech are AHRI-certified, guaranteeing that rated performance figures are independently verified under standardised test conditions.
ETL Certified
Intertek Electrical Testing Laboratories
ETL certification confirms electrical safety and compliance. It is the North American standard for electrical equipment and is accepted as a mark of quality worldwide.
ASHRAE 90.1 Compliant
American Society of Heating, Refrigerating & Air-Conditioning Engineers
Our systems meet or exceed ASHRAE 90.1 — the globally recognised energy efficiency standard for HVAC equipment in commercial and industrial buildings.
The difference that matters
Certified Equipment Only
We never supply uncertified equipment. Every unit we sell carries AHRI, ETL, or ASHRAE certification — protecting your project and your investment.
End-to-End Delivery
From load calculation and system design through to installation, commissioning, and long-term maintenance — we handle the entire project, not just the sale.
Nationwide Coverage
Operations in Dhaka, Chattogram, Sylhet, Gazipur, and Narayanganj with service teams deployable to all 64 districts.
20+ Years Experience
Since 2005, our engineers have handled over 500 HVAC projects — from 1-tonne residential installs to 2,000-tonne industrial chiller plants.
24/7 Emergency Support
Annual Maintenance Contracts include 24/7 emergency response. Downtime in industrial cooling is costly — we prioritise rapid dispatch.
Green Refrigerants
All modern systems use environmentally responsible refrigerants with zero or low GWP, including R410A, R32, R134a, and HFO-R513A.
