Which bus A/C problems do we fix?
Bus AC not cooling at all
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.Uneven cooling, front cool, rear warm
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.Loud noise from bus AC compressor
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 88893 60888 as soon as you notice noise.Water dripping inside the bus cabin
Water dripping from roof-mounted AC units is most often a blocked condensate drain, which we confirm before any repair. 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
