Safety-Focused Service
Machinery air conditioning
If the air conditioning in your machine has stopped cooling, Wilsons Plant can come to the machine in Southern Highlands. We diagnose, regas, repair and rebuild cabin air conditioning on plant, heavy vehicles and machinery, and most regas and leak detection jobs are done in a single mobile visit. We service machines for rural civil, agricultural and quarry operators across Southern Highlands.
A working cab air conditioner is a safety and productivity item, because heat related fatigue is a real risk on civil and mine sites. We treat an air conditioning failure like any other critical breakdown. Standard breakdown response is next business day, with contracted clients getting same day attendance where the route allows, and scheduled servicing can be pre booked into the fortnightly Highlands route. Call (02) 4285 5297 or send us the details, and we aim to send a quote back within the day for regas and leak detection jobs.
Fast response repairs and preventative maintenance for plant, fleet and heavy machinery. It suits operators who want to reduce downtime and manage breakdowns across all industries and environments.
Cab air conditioning servicing, regassing and repairs for plant and heavy machinery. Mobile support is available for cooling problems, operator comfort and system performance in harsh working conditions.
Vehicle fit-outs designed for mine site compliance, including battery isolators, fire extinguishers and safety signage, so your fleet is ready for approved site entry on NSW mining and civil projects.
Tell us the machine, the fault and where it is working in Southern Highlands. Most regas and leak detection jobs are done in a single mobile visit.
ON ARRIVAL
The technician tests for leaks with electronic sniffers, UV dye and pressure tests, and checks the compressor, condenser, evaporator and controls.
DURING THE VISIT
Refrigerant is recovered, the system is evacuated and recharged to manufacturer specifications, with R134a and R1234yf both handled. Compressor, condenser, evaporator, expansion valve, drier and hose repairs are carried out as needed.
AFTER THE VISIT
The system is leak tested before the machine goes back to work. Where a system is beyond economical repair we supply and fit a complete replacement sized to the cabin and duty cycle, and service sheets, photos and recommendations are sent within 24 hours.
Local servicing
We know the route from Picton up the range, the back roads into Robertson and the access into the larger Highlands properties. Our technicians are used to rural site safety expectations and to working around livestock and agricultural cycles, with extra coverage in peak servicing seasons, typically pre winter for civil contractors and pre harvest for agricultural clients.
Pre season air conditioning servicing lets fleets catch leaks before the heat hits and avoid the November scramble for compressor stock. For machines on a scheduled route, the air conditioning check can be booked into the same visit as other servicing.
About Southern Highlands
The Southern Highlands is a region about 110 kilometres south west of Sydney that takes in the Wingecarribee Shire. The major towns are Mittagong, Bowral, Moss Vale, Robertson and Bundanoon, the Shire is crossed by the Hume Highway and the Southern Highlands railway line, and the region is considered a wine region.
Agricultural and civil machines here often work long seasonal days on rural properties, and a cab air conditioning system that is checked before the warm months can save a mid season breakdown.
Our mobile technicians service machinery air conditioning in these Southern Highlands towns and villages: Alpine, Aylmerton, Avoca, Balaclava, Balmoral Village, Belanglo, Berrima, Bowral, Braemar, Bullio, Bundanoon, Burradoo, Burrawang, Canyonleigh, Colo Vale, East Kangaloon, Exeter, Fitzroy Falls, Glenquarry, High Range, Hill Top, Joadja, Kangaloon, Manchester Square, Mandemar, Medway, Meryla, Mittagong, Moss Vale, Mount Murray, New Berrima, Paddys River, Penrose, Renwick, Robertson, Sutton Forest, Wattle Ridge, Welby, Werai, Wildes Meadow, Willow Vale, Wingello, Woodlands, Yerrinbool.

A sealed air conditioning system should not lose refrigerant in normal use, so regular topping up is usually a sign of a leak rather than routine servicing. If the cab is not cooling as it used to, have the system tested for leaks before it is regassed. Many fleets book a check before summer so leaks are found before the heat arrives.
Common signs are weak cooling, air that is only cool rather than cold, and a compressor that cycles on and off or does not engage. These can also point to other faults such as a failing compressor, a blocked condenser or an electrical problem, so a diagnosis is worth doing before gas is added.
The usual causes are low refrigerant from a leak, a failed compressor or clutch, a blocked or damaged condenser, a faulty expansion valve or drier, or an electrical or control fault. We diagnose with electronic sniffers, UV dye and pressure tests, then repair the cause instead of only adding gas.
The cost depends on the machine, the size of the system, the refrigerant and whether a leak needs repairing first, so we do not quote a fixed figure without knowing the machine. Send us the details and we aim to return a quote within the day for regas and leak detection jobs. We run a fortnightly route into the Highlands, and clients can book air conditioning work into it.
Most modern bulldozers, excavators, loaders and other plant are fitted with enclosed cabs with air conditioning, and aftermarket systems are available for many older machines. If your machine has a system that has stopped working we can service it, and where a system is beyond economical repair we supply and fit a replacement sized to the cabin and duty cycle.
Yes. Wilsons Plant sends mobile technicians to machines in Southern Highlands, and our units carry recovery, vacuum, regas, leak detection and pressure testing equipment. Standard breakdown response is next business day, with contracted clients getting same day attendance where the route allows, and scheduled servicing can be pre booked into the fortnightly Highlands route. Call (02) 4285 5297 to book.
Yes. Our mobile units carry the equipment for refrigerant recovery, vacuum, regas, leak detection and pressure testing, so cab air conditioning on tractors, plant and heavy vehicles is normally serviced at your site.
Leaks are found with electronic sniffers, UV dye and pressure tests, and the system is then repaired at the source, evacuated and recharged. Regassing without finding the leak only delays the next failure.
R1234yf is a newer refrigerant with a much lower global warming potential than R134a and is used in newer systems. The two are not interchangeable, and a system needs the refrigerant it was designed for. Our technicians are certified to handle both.
The compressor circulates refrigerant around the system and raises its pressure so the system can move heat out of the cab. If it fails the system stops cooling, and the failure can send debris through the rest of the system, so the cause is worth finding.
