Tariqul Islam Chowdhury
Homeowner • Dhanmondi, Dhaka
"Outstanding service by ATC team! Called their 24/7 hotline at 11 PM because my bedroom inverter AC stopped cooling during humid weather. Technicians arrived promptly from Elephant Road. Professional jet wash and gas leak repair solved the issue immediately. Very polite and honest pricing!"
Farhana Rahman
Operations Manager, FinTech Office • Gulshan-2, Dhaka
"We signed an Annual Maintenance Contract (AMC) with ATC for our 18 cassette AC units. Sahed Nobel and his team are exceptionally punctual and thorough. Their preventive maintenance saved our server room from overheating twice. Highly recommend for corporate setups in Bangladesh."
Engr. Mahmudul Hasan
Resident • Uttara Sector 7, Dhaka
"I purchased a certified 2nd-hand Gree 1.5 Ton AC from ATC. Honestly, I was skeptical about used ACs, but ATC's 1-year replacement warranty and factory test report gave me confidence. It runs like brand new, ice cold cooling, and saved me over ৳30,000 compared to showroom price!"
Kazi Ashraful Alam
Managing Director, Textile Export House • Motijheel C/A, Dhaka
"Purchased 6 units of brand new General 2.0 Ton ACs directly through ATC's warehouse channel. Received 100% genuine units with original manufacturer warranty cards at significantly lower rates than marketplace stores. Seamless core-cutting and installation."
Dr. Nusrat Jahan
Consultant Physician • Mirpur DOHS, Dhaka
"The master jet wash service is phenomenal. Our old AC had bad mold smell and poor airflow. The ATC technicians disassembled the unit properly, washed it chemically without messing up my walls or curtains, and left the room spotless. Truly exceptional HVAC service in Dhaka."
