As the demand for services increases and fleets extend the lifespan of their assets, the significance of air conditioning and HVAC maintenance is rising. Equipment managers are focusing more on preventive maintenance, making the cab climate system a top priority.
“The goal is to get that truck out quickly and efficiently to avoid it coming back,” stated Kyle Gordon, technical support supervisor at MAHLE Service Solutions. “These technicians are on tight schedules, and no one wants to waste time troubleshooting the same problem multiple times.”
The Necessity of Maintaining Cool Temperatures
Consider the functionality of the HVAC system from an uptime standpoint. For vocational and regional-haul fleets, particularly those operating in high-temperature areas or featuring sleeper cabs with both front and rear A/C units, HVAC reliability is crucial. A comfortable driver translates to enhanced productivity.
The complexity of HVAC systems has grown significantly.
“We aim to assist technicians with diagnostics,” said Gordon. “Accelerating the service process without compromising quality benefits everyone — from the workshop to the driver on the road.”
Advanced diagnostic tools and machines, like those offered by MAHLE, provide live pressure assessments to help heavy-duty technicians quickly identify leaks and pressure issues.
Don’t Neglect Fluid Maintenance, Especially ATF
Just like ensuring driver comfort and productivity, it’s vital to keep all system components functioning efficiently. Take transmissions, for example. Gordon points out that many fleets neglect automatic transmission fluid (ATF) changes, mistakenly believing that modern systems are maintenance-free.
This belief can be costly.
“New fluid is always superior to old fluid,” Gordon emphasized. “Despite advancements in transmission technology, wear and tear from friction and clutch material buildup can hinder performance.”
To streamline the service process, MAHLE has launched the ATX 280, a fluid exchange machine that tracks flow through dipsticks or cooler lines, providing various service mode options.
“Whether in pan-off or dipstick mode, the machine guarantees that fluid flows properly,” he added. “Smooth gear transitions depend on clean fluid. Neglecting this can lead to rough shifts, limited flow, and eventual failure.
“Fluid is relatively inexpensive. Repairs can be quite costly these days. Investing a bit more in maintenance now can save thousands later, which benefits you, your technicians, and your fleet.”
