What is an AC Annual Maintenance Contract?
An AC Annual Maintenance Contract (AMC) is a service agreement where Greenzone takes full responsibility for the upkeep of your commercial HVAC system throughout the year. Instead of calling for service only when something breaks — which usually happens at the worst possible time — an AMC ensures your system is regularly inspected, cleaned and tuned before problems develop.
For commercial establishments in Patna, Ranchi, Gaya and across Bihar and Jharkhand — banks, hospitals, hotels, schools and corporate offices — HVAC downtime is not just uncomfortable, it is costly. A Greenzone AMC eliminates that risk.
