Ductable & Cassette AC — What is the Difference?
Both ductable AC and cassette AC are central air conditioning solutions for large commercial spaces in Bihar — but they work differently and suit different types of buildings. Greenzone installs and services both types across Patna, Ranchi, Gaya, Muzaffarpur and all major cities in Bihar and Jharkhand.

Frequently Asked Questions
Which is better — ductable AC or cassette AC for offices in Patna?
It depends on your office size and layout. For large open-plan offices (2000+ sq ft), ductable AC gives better uniform cooling. For medium offices with separate cabins, cassette AC is more flexible. Our engineers will recommend the best option after a free site survey.
How long does ductable AC installation take in Bihar?
A typical ductable AC installation for a 3000-5000 sq ft commercial space in Patna takes 5-10 working days including duct fabrication and civil work coordination.

Can cassette AC work without a false ceiling in Bihar?
Cassette AC units require a false ceiling for flush mounting. If your space in Patna or Bihar does not have a false ceiling, a ductable system with surface-mounted ducts or a VRF system with wall-mounted indoor units may be more suitable.
