Transparent Fleet Pricing

No hidden charges — ever. Every fleet job gets a clear, itemised estimate before work begins. Call +91 8428000085 for honest fleet rates.

Common Bus AC Problems We Fix

Usually caused by total refrigerant loss (major leak), failed compressor clutch, or a tripped electrical fuse or relay. Our technicians systematically diagnose the exact root cause before recommending repairs — no guesswork.

Common in mini buses with dual-zone AC systems. Causes include a blocked rear evaporator, refrigerant imbalance, or faulty rear blower motor. We inspect both zones and restore uniform cooling throughout the passenger cabin.

Grinding, knocking, or squealing from the compressor indicates bearing failure, worn clutch, or internal damage. Early diagnosis prevents a minor bearing issue from becoming a full compressor replacement — contact us at +91 8428000085 as soon as you notice noise.

Water dripping from roof-mounted AC units is caused by a blocked condensate drain. Left unattended, it damages upholstery and electrical wiring. We clear drains and inspect drain trays as part of every bus AC service.

Keep Your Fleet Moving

A non-functional bus AC in Chennai's summer directly impacts your business — passenger complaints, driver fatigue, and route disruptions. Don't wait.
