Truck & Machinery AC Services in Hunter Valley & Central Coast
When a dozer cab hits 45°C mid-shift or a Kenworth’s AC quits on the Pacific Highway approach to Gosford, the cost isn’t just operator discomfort — it’s lost productivity, WHS obligations and, in some cases, a machine that can’t legally run a full shift. Truck and machinery AC service in the Hunter Valley and Central Coast is what RAM Auto Electrical specialises in. Our fully equipped service vehicle carries recovery and recharge machinery, electronic leak detection gear, and the refrigerant types used across heavy plant — R134a and R404A — so we can complete most jobs in a single visit without waiting on parts. Plant hire businesses that need documented, reliable repair records for fleet auditing or insurance purposes get a plain written summary of exactly what was found and fixed. For broader mobile electrical work on civil machinery, see our

Machinery AC Regas
R134a and R404A refrigerant regas performed at your site with calibrated recovery and recharge equipment.
Leak Detection & Repair
Electronic sniffers and UV dye pinpoint refrigerant loss in high-vibration heavy plant environments before compressor damage occurs.
Compressor Diagnosis
High-capacity compressor clutch, bearing and internal faults assessed and replaced to restore full cab cooling on trucks and plant.
Cab Climate Diagnostics
Blend doors, pressure switches, blower motors and control units tested across the full cab HVAC circuit — not just a pressure check.
System Pressure & Output Test
Post-repair pressure testing and vent temperature verification confirm the system is performing to specification before we leave the site.

Built for plant hire operators, civil contractors & fleet managers across Hunter Valley & Central Coast.
A plant hire business running a mixed fleet of excavators and graders can’t afford to truck machines to a workshop every time the cab AC fails — especially mid-contract on a civil project near Cessnock or Wyong. RAM Auto Electrical comes to the machine, quotes the repair before starting, and provides a written record of what was done. That documentation matters when you’re managing assets for a rental fleet or need to demonstrate maintenance compliance.
